1/4. Rising CO2 levels improve plants' water use efficiency and drought resilience, through reduced stomatal conductance. Simply put, plants need to process less air to get the carbon they need for growth, and thus they lose less water to transpiration.
x.com/ncdave4life/st…

That's one of the reasons that catastrophic famines no longer happen. For all of of human history, until recently, famine was one of the great scourges of mankind: the "Third Horseman of the Apocalypse." But widespread famines are fading from living memory, and rising atmospheric CO2 concentration is one of the reasons for that.

That's a very, very Big Deal. For comparison:

● COVID-19 killed about 0.1% of the world's population
● The catastrophic 1918 flu pandemic killed about 2%
● WWII killed 2.7% of the world's population
● But the nearly-worldwide drought and famine of 1876-78 killed about 3.7% of the world's population.

3/4. I asked ChatGPT about that benefit of CO2 emissions and rising CO2 levels:

"With reference to the agronomy literature, quantify how elevated CO2 helps plants use water more efficiently, and increases crops' drought resilience, by reducing stomatal conductance and water loss through transpiration."

ChatGPT replied with a very good answer:

In agronomy, the effects of elevated CO2 on plant water use efficiency and drought resilience are extensively studied. One of the key mechanisms through which elevated CO2 levels improve water use efficiency is by reducing stomatal conductance and, consequently, water loss through transpiration.

Stomata are small pores on the surface of plant leaves that regulate gas exchange, including the uptake of CO2 for photosynthesis and the release of water vapor through transpiration. When CO2 levels are elevated, plants can maintain the same or higher rate of photosynthesis while reducing stomatal conductance. This reduction in stomatal conductance leads to a decrease in water loss through transpiration without significantly affecting CO2 uptake, resulting in improved water use efficiency.

Several studies have quantified the effect of elevated CO2 on stomatal conductance and transpiration. For example, a meta-analysis published in 2013 (Kimball et al., 2013) found that under elevated CO2 levels, stomatal conductance decreased by an average of 22%, while transpiration decreased by only 17%. This indicates that plants under elevated CO2 levels were able to reduce water loss more efficiently than they reduced CO2 uptake, leading to an overall improvement in water use efficiency.

Improvements in water use efficiency due to elevated CO2 levels can increase plants' drought resilience by allowing them to maintain adequate hydration during periods of water scarcity. This can be particularly beneficial in arid and semi-arid regions where water availability is limited.

Overall, the literature suggests that elevated CO2 levels can improve water use efficiency in plants by reducing stomatal conductance and water loss through transpiration, which can enhance their resilience to drought conditions.

1/8. Gov. Newsom's press release falsely blames "a hotter, drier world." In fact, the world is warming only very slightly & slowly, and it hasn't gotten at all drier. Here're the facts:
sealevel.info/learnmore.html…
As you can see from the graph, the fraction of the globe in drought has decreased slightly, not increased.

Oh, and BTW, NCA4 (circa 2018) estimated that global average temperatures have risen only 1.14 ±0.13°C since the 1800s, and the warming is disproportionately at chilly high latitudes.Image
2/8. Also, higher CO2 levels greatly reduce drought impacts, by making plants more drought-resistant and water-efficient, through reduced stomatal conductance. That's very beneficial in arid regions, like the Sahel & much of California. Here's an article.

MBH98 features its famous hockey stick graph in two figures. By mistake, an older version of the reconstruction was actually used for one of the figures.

I like a good puzzle so decided to do some reverse engineering on the "old" MBH98 reconstruction. 🧵 Image
Image
MBH98 uses the old reconstruction for signal detection. Since the forcing data begins in the early 1600s, only the post-1600 portion of the reconstruction is shown in the paper.

The goal of this thread is to reproduce that part of the reconstruction and then extend it. Image
The post-1760 portion also appears in an earlier paper by Mann and Bradley (MB98). This paper will be useful. Image

"Pro-choice"? Not so much.

A thread about a shocking new legal tactic we're seeing from pro-abortion officials in multiple states. 👇Image
We’re currently litigating cases in NY, CO, and CA where state officials have tried to ban/punish pro-life speech.

These officials are trying to punish doctors, nurses & pregnancy centers who provide a treatment called abortion pill reversal (APR)... or even TELL women about it.
These politicians accuse APR providers of “misleading” women. But the evidence says otherwise.

APR uses progesterone, a natural hormone which has been safely prescribed to pregnant women for decades. Progesterone can counter the deadly effects of mifepristone when taken in time.

But it was the idiosyncrasies of Gleick's own writing style, found in the forged document, which Mosher mostly discussed, when explaining why he believed Gleick wrote it.

Mosher explained it, at length, in a series of blog comments, beginning here:

Note that that was all BEFORE Gleick confessed to being the person who had impersonated the Heartland Board Member to steal the other documents. THAT iced it: there's no question that Gleick was the forger.

1/5. I trust that it is obvious to you that the most important effects of climate change are on agriculture. Right?

So if you really want to read the best relevant scholarly literature, you should start with agronomy papers. Agronomy is a much older, more rigorous, and less politicized field than "climate science," and it's the field which studies the effects of CO2 and climate change on agriculture.



Here are "cereal crops" (wheat, corn, rice, etc.), averaged:

That said, people do seem to think that debates are woven into the fabric of American presidential politics, They're not. The first one that we had that would be recognizable to contemporary American eyes was Nixon/Kennedy in 1960.
After that we didn't have another until Ford/Carter in 1976. From that point on debates have been a regular feature, but this is all a relatively new thing.

1/15≫ Dr. Belch (why oh why isn't she a gastroenterologist?) seems not to recognize the significance of the story.

Climate activists predicted that if Earth's average temperature got to 1.5°C above the pre-industrial (late Little Ice Age) baseline it would be a disaster. But they did, and nothing bad happened.

The significance of that is that it means the climate activists were completely wrong.
2/15≫ In case you're wondering, the 4 known factors which caused 2023 to be so mild were:

1. A strong El Niño spike. And

2. IMO 2020 shipping regulations drastically reduced sulfate aerosol air pollution (The IMO says they resulted in "an estimated 46% decrease in ship-emitted aerosols," which equates to a sudden 10% decrease in total global SO2 emissions, which is a large improvement in a short time, with a significant warming effect). And

3. The unusual 2022 Hunga Tonga eruption, which humidified the stratosphere. And

4. Also a little bit of warming from the ongoing slow rise in atmospheric CO2 levels (though only about 25 ppmv/decade).

It's all good, though (unfortunately) #1 & #3 are temporary.
3/15≫
Q: And what was the result of all that warmth?

A: Nothing. Nothing bad, anyhow.

We still get storms, but they're no worse than in the past.

1/7. This PBS piece is extremely misleading. Elevated CO2 greatly improves crop yields, and it mitigates drought impacts, by improving plants' water use efficiency (WUE) and drought resilience. See:


I asked ChatGPT to explain the mechanism by which agronomists have found that elevated CO2 improves crops' WUE and drought resilience. It did a good job:
‍‍‍‍‍‍ ‍‍
‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍꧁꧂

I've also already explained to you why the natural sinks which remove CO2 from the air will continue to accelerate as long as CO2 levels continue to rise.
3/7. Natural CO2 removal mechanisms, which already remove at least (5.4 Gt CO2 / 2.1294 Gt/ppmv) = 2.5 ppmv/year, accelerate by an additional 1 ppmv/year for every 40-50 ppmv increase in atmospheric CO2 concentration.


That's a very powerful "negative feedback" which limits the rise in CO2 concentration, and ensures that the temperature increase will remain modest and benign.

1️⃣/4️⃣. That graph shows an estimate of a total of about 500 ZJ added to the the upper 2 km of the oceans since 1955.

Aside: Actually, the first 50 years of the graph are nothing but guesses.

OHC is estimated by models, informed by temperature measurements, made by Argo floats. The first Argo float was deployed in 2000. They didn't reach 3000 units (i.e., one float per 120,000 km²) until 2007.

So the part of their graph prior to about 2005 is 100% codswallop. The kindest thing you can say about it is that it's a plausible guess, consistent with (but you can't say based upon!) convenience samples of sea surface temperatures. It is not data, in any sense.

But never mind that, because that graph also has another problem...
2️⃣/4️⃣. Does it seem odd to you that, even though all the measurements are of temperature, rather than heat content, THEY NEVER REPORT TEMPERATURES?

You should calculate what 500 ZJ means in terms normal people can grok: average water temperature change. If you do that simple exercise, it will be obvious why they do not report it.
3️⃣/4️⃣. I know you won't do it, so I'll do it for you. (You're welcome.)

Total volume of water in the oceans is 1,338,000,000 cubic-km = 1.338e9 km³.

Volume of water in the upper 2000 meters of the oceans: 3.6e8 km² × 0.95 × 2.0 km = 6.84e8 km³ = ≈50% of total ocean volume.

The density of seawater is about 1027 kg/m³ = 1.027 tonne/m³ = 1.027 Gt/km³.

6.84e8 km³ of seawater weighs:
1.027 × 6.83e8 = 7.0e8 Gt

1 Gt = 1e12 kg, so the top 2 km of the world's seawater masses:
7.0e8 Gt × (1e12 kg/Gt) = 7.0e20 kg

So, let's calculate how much energy it takes to warm that much water by 1°C.

Everyone knows 1 cal of energy will raise one gram of fresh water by 1°C, and 1 kcal (1000 cal) warms 1 kg of water by 1°C. 1 cal = 4.184 J, so 4.184e3 J warms 1 kg of pure, fresh water 1°C.

Seawater has an 8% lower specific heat of 3.850e3 J / (kg °C). So:

It takes 7.0e20 kg × 3.850e3 J/kg = 2.695e24 Joules to raise the average temperature of the top 2 km of the oceans by 1°C.

So 500 ZJ (= 5.0e23 J) warms the top 2 km of seawater by an average of (5e23 / 2.695e24) = 0.185 °C, or almost 1/5 of 1°C.

@NASAClimate 1/11. When someone talks about a sea-level measurement record starting in 1993 it means they're using low quality satellite altimetry data, and they're ignoring the much higher quality coastal measurements. It's political propaganda, not unbiased science.
sealevel.info/satellite_alti…
2/11. If you use the (much higher quality) coastal measurement data, it becomes clear that there's nothing to worry about.


That's Honolulu, which has the best quality, well-sited, sea-level measurement record in the world. The "straightness" of the blue sea-level trend means that rising CO2 levels haven't had much effect on sea-level.sealevel.info/learnmore.html…
@NASAClimate 3/11. The "straightness" is called "linearity," and it's opposite is called "acceleration." If you don't know how to recognize "acceleration," "deceleration," or "linearity" in a graph, here's a little primer which should help:

1/9. @NASAClimate is not one of the divisions & departments of NASA that do science. It's the "JPL Earth Science Communications Team" in Pasadena, which is comprised of "communicators," not scientists.

NASAClimate is a frequent source of misinformation and outright political propaganda.sealevel.info/learnmore.htmlImage
@NASAClimate 2/9. Many other parts of NASA still employ real scientists, who do excellent work.

Here's a NASA video about some of that work.

CO2 emissions are very beneficial for natural ecosystems, and NASA satellites measure the resulting "greening" of the Earth.
@NASAClimate 3/9. Do you worry about the Antarctic Ice Sheet melting? This excellent NASA study should put your fears to rest.



Note: Antarctic temperatures average below −40°, so a few degrees of warming obviously cannot melt it. cambridge.org/core/journals/…

3/10. Although C4 plants are better at scavenging CO2 from the air at low levels than are C3 plants, the most important C4 crops, corn & sugarcane, have been found to benefit dramatically from higher CO2 levels.


(That's probably because they grow so fast. On a still, sunny day, a healthy corn field can deplete the CO2 in the air by noon, at which point it stops growing. With a higher starting level, it can grow longer before running out of CO2.)

2/17. That DeSmogBlog article about Will Happer is a brazen, despicable smear.

DeSmogBlog claimed that "Peabody Energy paid [Happer] $8,000 which was routed through the CO2 Coalition."

That's a LIE. Prof. Happer was not paid, because he asked that his entire fee be donated to charity.
3/17. DeSmog also falsely claimed, "Happer told Greenpeace reporters that he would be willing to produce research promoting the benefits of carbon dioxide for $250 per hour, while the funding sources could be similarly concealed by routing them through the CO2 Coalition."

That's ANOTHER LIE.

Happer did no such thing. Rather, he was asked to produce a white paper (which is not "research") explaining the best scientific evidence about the costs and benefits of fossil fuel use—and he generously asked that the fee for that work be donated to charity.

The CO2 Coalition @CO2Coalition is a 501(c)(3) educational charity. Happer didn't "route" anything "through" them. He very generously donated the fees to which he was entitled, to that very worthy charity.

2/6. The 14C bomb spike decay reflects 3 main processes:

1. Removal of CO2 from the air, into other "reservoirs" (ocean & terrestrial biosphere).

2. Exchanges of carbon between atmosphere & other reservoirs.

3. "Suess effect" dilution: the addition of fossil CO2 with no 14C.Image
3/6. The bomb spike decay follows a beautiful logarithmic decay curve, with an 11 year half-life, so an 11 / ln(2) = 16 year apparent lifetime. But that fails to take into account Suess effect dilution.

1/5. Stoichastich wrote, "He says quite clearly that the hothouse is warm because the glass absorbs dark rays from the ground (IR), which is clearly not why the hothouse is hot."

That's not what Arrhenius wrote. This is the paper:


This is the excerpt to which I think you must be referring:

"Fourier maintained that the atmosphere acts like the glass of a hot-house, because it lets through the light-rays of the Sun, but retains the dark-rays from the ground."

You've mistaken his meaning. In the first place, Arrhenius was summarizing what another scientist said. In the second place, the word "it" clearly refers back to "the atmosphere," not to the hot-house, as you've apparently supposed.

The main way that greenhouses retain heat is by preventing convective and evaporative cooling. That's why greenhouses made of plastic which is transparent to LW IR work just fine. (Glass greenhouses do get a small amount of additional warming effect by blocking outgoing LW IR.)iopscience.iop.org/article/10.108…
2/5. Stoichastich asked, "Where has anyone said that [Arrhenius] did use that term?"

You retweeted Dale Cloudman pointing out that "the greenhouse effect is a misnomer," in your tweet saying that Arrhenius' paper was "fundamentally flawed." So I thought that's what you meant.
3/5. Stoichastich asked, "Estimating it sounds interesting, but has it ever been measured?"

There've been some attempts both to calculate and to measure the "radiative forcing." I summarize them here:

1/7》GCP emission data shows 185.58 ppmv of fossil carbon emissions from 1959-2021 (plus a poorly constrained amt of non-fossil "land use change emissions"). Only about 5.56 ppmv (3%) was CO2 released from limestone [CaCO3] as it's baked to make cement.
@Piyush__Tank @JessePeltan 2/7》It's estimated that, on average, as concrete weathers it absorbs roughly half as much CO2 as was released from the limestone when it was made. That halves the 3% (5.56 ppmv) figure to 1.5%. The process is akin to natural rock weathering:

3/7》It's often claimed that cement manufacturing causes "up to 8%" of anthropogenic CO2 emissions, but that figure includes estimated emissions from the fossil fuels burned to heat the kilns, typically accounting about half the total (though it varies according to how the kilns are fired).

1/5. Willard, why do you ask questions that were answered at links I just gave you—that you refused to read?

I linked to a 7-part tweetstorm about the discredited Shakun/Marcott/Pages2K/Hagelaars "wheelchair" graph, which goes back 22K years. It completely erased D-O event #1, every last trace of it.
2/5. That wheelchair graph also erased all but ¼℃ of D-O event #0, a/k/a the Younger Dryas termination, a/k/a the start of the Holocene.
3/5. It also shows the middle of the Dark Ages Cold Period as slightly warmer than the middle of the Medieval Warm Period.

1/6. From measurements of downwelling LW IR, 342 W/m² is a reasonable, approximate estimate of downwelling LW IR radiation averaged over the entire surface of the Earth.

It's essentially identical to MacCracken's 1985 estimate (which he called "only an approximation"):

(Note: the numbers are percentages.)

The quoted text excerpt is:
“The fluxes of energy within the atmosphere-surface system can be illustrated using an energy balance diagram. Although many measurements have been made at the surface and from satellites, there are still uncertainties of 10-20% in the values of some of the fluxes because of the difficulty of making representative global measurements. In some cases model calculations have been used to generate estimates. The values shown in the diagram in Figure 1.2 are derived from consideration of energy balances prepared by Gates (1979), Liou (1980), and MacCracken (1984), and are only an approximation.”

Source:
M. C. MacCracken and F. M. Luther (Ed.), "Projecting the Climatic Effects of Increasing Carbon Dioxide," United States Department of Energy, DOE/ER 0237, Dec. 1985.


Note that the main source of uncertainty is not that we cannot measure downwelling LW IR. Rather, it is "the difficulty of making representative global measurements." Actual downwelling LW IR fluxes vary wildly with time and location, so finding an accurate global average is problematic, to put it mildly.sealevel.info/MacCracken1985…

@joelgombiner @RARohde 1/5》I agree. Without those ice sheets, there's no source for vast influxes of freshwater into the northern North Atlantic, to slow the AMOC.

There are a few key lessons to be learned from Dansgaard-Oeschger events (and D-O #0, a/k/a the Younger Dryas).
sealevel.info/learnmore.html…
@joelgombiner @RARohde 2/5》Because D-O terminations had warming trends an order of magnitude faster than current warming, and because nearly all extant species survived those large, sharp warming events, we needn't worry that the current slight warming could cause extinctions.
archive.is/aUi9R#selectio…
3/5》Because D-O events only occur during glaciations, and never during interglacials, we can say with confidence that warmer climates are more stable than colder climates.


That might be largely because without the great northern ice sheets, there's nothing which could pour vast quantities of freshwater into the northern North Atlantic, slowing the AMOC.

It's surely also because Planck Feedback is ∝ T⁴, so the warmer the climate gets, the stronger that negative (stabilizing) feedback is.

The CO2 Coalition is an organization of volunteer scientists, dedicated to combating disinformation about CO2 & climate change, and pushing back against the corruption of science for political & pecuniary reasons.

Many of the CO2 Coalition's members are extremely distinguished. Their newest Board Member is Dr. John Clauser, 2022 Nobel Laureate (Physics).

1/4≫ You're in denial, Gerald.



This is fact:

The best scientific evidence, confirmed by thousands of robust studies, shows compellingly that anthropogenic warming is modest and benign, and CO2 emissions are highly beneficial, just as Arrhenius predicted, over a century ago.

Why won't you read these excellent papers?sealevel.info/negative_socia…

E.g., do you REALLY believe that global average temperatures 3000 years ago are known with a 1σ uncertainty of just 0.2°C, and 2σ (95%) of just 0.4°C? You've GOT to know that's absurd!

A blast of extreme cold air has plunged deep into central North America. Some places have set record cold temperatures. It turns out there’s a bit of a scientific debate about whether these types of cold snaps can be linked to… *global warming*

🧵on what the science says… Image
The general idea is that melting sea ice within the warming Arctic is causing instability in the jet stream, resulting in large Rossby waves which during the winter season can push frigid Arctic air deep into areas where they wouldn’t in a more stable climate…
The idea really gained traction after this 2012 paper came out, titled “Evidence linking Arctic amplification to extreme weather in mid-latitudes”: agupubs.onlinelibrary.wiley.com/doi/full/10.10…

Trash look from the most vocal proponent of the Arctic warming causes extreme winter cold theory Jennifer Francis: she calls Republican voters in Iowa "deniers" for not believing that global heating causes extreme cold in Iowa. Most other climate scientists don't either.
Jennifer Francis is not unique in her bigoted view of Republicans among her climate science colleagues.

However, this type of partisan rhetoric is required to operate within the climate science space to receive promotion, grants, and awards. It's rather ugly.
More than 10-years ago, a weak defense of her theory appeared in the Washington Post.

It was a signal to other early career researchers to back off by questioning the motivation and objectivity of another academic. A real ugly and trash look.

Some coral inhabit temperate zones, but most prefer tropics. In fact, where there are seasons, corals grow fastest in summer.

In fact, where there are seasons, corals are commonly dated like trees, by "coring" them, and examining the growth rings. The thick rings represent summers, because that's when the coral grows fastest.

The temperature indexes are inconsistent, but you can't tell that from Priscian's misleading graph.

An honest graph would offset the traces so you can tell them apart, or else start them at the same temp. Instead he aligned the full-period averages, to hide the spread.

Here's what he's hiding:



What Jim Java / Priscian doesn't want you to notice is that the GISS (and Berkeley Earth, etc.) surface temperature indexes show much more warming than the UAH and NOAA STAR satellite-based lower troposphere measurements.

Land "surface" measurements are air temperatures measured with thermometers in Stevenson screens, usually 1.25 to 2 meters above ground. Satellite "lower troposphere" indexes (UAH, NOAA STAR, RSS) are from higher altitudes. Due to "lapse rate feedback," the (higher) altitudes where satellites measure temperatures should  see a slightly greater  warming trend than is seen 1.25 to 2 meters above the surface. Instead, they see less.


That's good cause to suspect that the surface temperature indexes from GISS etc. overstate warming.woodfortrees.org/plot/gistemp/f…
sealevel.info/GISS_vs_UAH_an…
sealevel.info/feedbacks.html…Image
2/8》
Do the math: 0.92 / 0.59 = 1.56

So, UAH6 & NOAA STAR satellite-based measurements suggest that those high-end surface temperature indexes are reporting at least 56% too much warming.

But even if it is exaggerated, the warming isn't worrisome. After all, humans are a tropical species, and most of the Earth is much too cold.


Warming saves lives, and excess cold causes many times more human deaths than excess heat — even in tropical counties, believe it or not! Here are some recent papers about it:

1. Masselot et al (2023).


2. Gasparrini et al (2022).

Composite of two figures from the paper:


3. Zhao et al (2021).

Discussion:

Summary:


4. Gasparrini et al (2015).

Fig. 2:


Are you familiar with the term "climate optimum?" If you go to ResearchGate or Google Scholar, and search for "Climate Optimum" (or Eemian Optimum, Mid-Holocene Optimum, Roman Optimum, or Medieval Optimum), you'll find thousands of papers using that terminology. Those "optimums" were warm periods.


The reason so many academic papers call the warmest periods in history "climate optimums" is that there is a consensus among historians and scientists that those warm "climate optimums" — including periods warmer than now — were, by all objective measures, better than colder periods.

Or, look at the flip side: cold periods, like the Dark Ages Cold Period (DACP) and the Little Ice Age (LIA). There's a broad consensus that those cold periods were, by all objective measures, worse for humanity than the warm "optimums."


Here's a 1974 CIA study about the threat of global cooling:


This graph from that study shows how cooling temperatures threaten food supplies:

Depending on whose temperature index you use, we’ve seen an average of between 0.59 and 0.92 °C of warming since 1958 (when Mauna Loa CO2 measurements began).



That warming has shifted growing zones and “temperature isotherms” slightly toward the poles (northward, in the NH). So, the obvious question is, how far?

That’s easy to answer, by looking at an agricultural growing zone map. Here's one, shared by permission from the Arbor Day Foundation:


From eyeballing the map, you can see that 1°C (1.8°F) = about 50-70 miles latitude change.

Here's James Hansen and his GISS colleagues reporting a similar figure:

Excerpt: "A warming of 0.5°C... implies typically a poleward shift of isotherms by 50 to 75 km..."

That's 100 to 150 km = 62 to 93 miles per 1°C. So, the 0.59 to 0.92 °C of warming which we've seen has caused, on average, a growing zone shift of only about 30 to 86 miles). Ho hum.🥱woodfortrees.org/plot/gistemp/f…

3/3. Do you know where the "extreme weather" nonsense came from? Not from evidence, but from James Hansen's epic confusion.

Somehow he avoided learning about Arctic Amplification. He thought AGW would warm the tropics MORE than high latitudes.


That's a clip of Hansen on Letterman, explaining it. Hansen claimed that the “increasing temperature gradient” [between high & low latitudes] would "drive stronger storms.”

That's just plain wrong. The temperature gradient is DECREASING, not increasing.

You see, "global warming" isn't really very global. Thanks to stronger-than-linear negative feedbacks, such as Planck cooling, warm climates are more stable than cold climates. So AGW disproportionately warms chilly high latitudes. The tropics are affected much less (which is nice, because the tropics are warm enough already).


Hansen wrote a ridiculous book based on his confusion, and did a whirlwind publicity tour, pitching the book & spreading the claim that AGW will cause worsening storms / weather. (That's why he was on Letterman.)


Nearly all climate scientists know that's wrong, but none of them challenged him. Nearly everyone in the climate biz (maybe even Hansen, by now), has heard of Arctic Amplification, but the climate industry is so corrupt that neither Hansen's colleagues nor anyone else in the industry corrected his error.

1/5》 Do the math, Martin!

WMO estimates a total of 1.15 ±0.13°C of warming since "preindustrial" (late LIA).

At most  80% of human GHG forcing was from CO2, so even if ALL  the warming was from GHG emissions, 1.15°C means at most 0.92°C was from CO2.


Here's the WMO reference:


NCA4 gives a similar figure (1.14 ±0.13°C).

(Aside: those confidence intervals are, IMO, overly confident.)

Here are estimates for the percentage of warming due to CO2.

AR6:


NOAA's AGGI (compare heights at the right edge):


Myhre 1998:


AMS (compare the numbers in the "Rad. Forcing" column):


Kiehl & Trenberth 1997:
google.com/search?q=1.15+…
2/5》 If we got at most  0.92°C of warming from 58% of the forcing of a full doubling of CO2, then (at most) how much warming we could get from a full doubling of CO2?

Ask google:
google.com/search?q=0.92+…
3/5》 Those figures are very conventional estimates, widely accepted by climate alarmists. Yet those same climate alarmists believe that TCR climate sensitivity is 1.5 to 2.0°C/doubling of CO2, and ECS is about 3.0°C/doubling of CO2.

1/10. Where on earth do you "learn" such nonsense, Willard?

Growing ranges for most major crops cover climate zones with average temperatures that vary by tens of °C. Major crops like corn, wheat, potatoes & soybeans are produced from Mexico to Canada.

Compared to that, a degree or two of warming (disproportionately at night, in winter, at chilly high latitudes) is de minimis -- as is the 0.35±0.13°C between now and what the IPCC calls "1.5°C of warming").

That's false. It's long been known that warming generally improves agricultural productivity. Here's a CIA study which summarized the relation:
2/10. Fig.7 from that study shows the number of people who could be supported per hectare of arable land, vs. temperature. The 7 curves represent varying precipitation rates. In each case, higher temperatures allow the support of higher populations, due to better crop yields.

1/4. We've been over this, Willard.



According to NOAA's AGGI chart, over the last 1/3 century CH4 has accounted for just 8.6% of the radiative forcing increase from anthropogenic GHGs. Not 18% or 25%.

That's about 1/10ᵗʰ of the contribution which we get from the ongoing rise in CO2. If that tiny contribution to modest and benign warming worries you, perhaps counseling would help.
2/4. Here's the CH4 graph:



Despite the modest uptick in CH4 level over the last 15 years, the rate of rise in CH4's radiative forcing is still much slower than it was 50-60 years ago.

In the 1960s and 1970s the CH4 level rose relatively fast, and consequently CH4 was a larger contributor to radiative forcing increase.sealevel.info/CH4.html

"The western world's leading climatologists have confirmed recent reports of a detrimental global climatic change… during 50 of the last 60 years the Earth has, on the average, enjoyed the best agricultural climate since the eleventh century… The world is returning to the type of climate which has existed over the last 400 years. That is, the abnormal climate of agricultural-optimum is being replaced by a normal climate of the neo-boreal era. The climate change began in 1960…"

The grim climate to which we were thought to be returning was the Little Ice Age. "Boreal" means cold:

boreal. adj. Relating to or characteristic of the climatic zone south of the Arctic, especially the cold temperate region dominated by taiga and forests of birch, poplar, and conifers…
‍‍‍‍‍‍ ‍‍
The global cooling scare was one of the main reasons for the shiny new anti-air-pollution laws governing power plants, in the 1970s. The other main reason was "acid rain." (Note: Unlike "acidified" oceans, which are actually alkaline, acid rain really is acidic.)

1/25. The leading organization promoting the Climate Industry's "climate emergency" PR campaign is the IPCC. It has severe credibility issues. Investigative journalist Donna Laframboise explains some of them in this lecture about the IPCC's 2007 AR4 Report:


(It's 31 minutes but she speaks very clearly, so she's perfectly understandable at 2x speed.)


(Caveat: I've been an IPCC Expert Reviewer on a couple of their assessment reports.)
2/25. It's only gotten worse since then. The IPCC's 2022 AR6 Report explicitly promotes what I call "homeopathic climatology" (TCRE/RCB), which represents an overt rejection of science.
3/25. The TCRE ("Transient Climate Response to cumulative CO2 Emissions") and RCB ("Remaining Carbon Budget") concepts are homeopathy applied to climatology: the belief that the mere memory of a substance is all that's necessary for it to have its effect.

The reason climate activists aren't worried about China's CO2 emissions is that they aren't really worried much about emissions. They're mainly worried about keeping Piggy fed.

They don't call it a crisis "for nothing." $1.5 trillion/year ain't "nothing."

It's all about the Benjamins. They call it a crisis to amp up support for feeding Piggy. The parasitic climate industry needs a LOT of propaganda to prop it up.

Are you sure about that, Joe? Then riddle me this:

A. What does "heat capacity" mean?

B. What does "heat content" mean? (E.g., "ocean heat content" [OHC].)

Those are "open book" questions. Feel free to use a dictionary, or search google scholar, etc. In fact, I'll help you get started:

Re: lapse rate, and what the air absorbs

Joe wrote, "The atmosphere has different T’s based on what it absorbs from above or below."

That's correct, in part. †

But Joe also wrote, "lapse rate is not enhanced by CO2."

Here's the thing: CO2 in the air affects "what [the atmosphere] absorbs from above and below."

This is Earth's emission spectrum (measured from orbit, over the tropical Pacific). The big notch which I've annotated in green is due to CO2 in the air absorbing radiation from below (and also emitting radiation from air at colder temperatures):


(† However, asking what causes the zip-zag lapse rate shape was kind of a trick question, because there are several causes, and thermodynamic expansion/ compression of air is another, and condensation/ evaporation of moisture is a third.)
3/4.
CO2 (and other GHGs) are colorants. They tint the atmosphere (though in the far infrared, rather than visible part of the spectrum). That causes the air to absorb radiation that otherwise would have passed through. Absorbing radiation warms the air.


It doesn't take much "colorant" to have a substantial effect on absorption of radiation.

1/5. If you learn about agronomy from climate-activist journalists, instead of agronomists, you're sure to be misled. Author Eleanor McCrary @ellie_mccrary apparently started from a 2018 disinformation piece by freelance journalist Annie Sneed @aisneed.

The Sneed article is entitled "Ask the Experts…" and the McCrary article is entitled "…Experts Say." Yet both of those journalists are so clueless about their topic that neither of them even knew who the "experts" were to ask! For their articles about agronomy, neither author spoke to a single agronomist!!

1/6. I agree that that air pollution probably masked the warming effect of GHGs during the 1940s-1970s cooling period. But "measured warming" often uses baselines starting in 1979, because that's the start of satellite-based temperature measurements.


The correlation between temperatures and aerosol/particulate air pollution abatement is not perfect, but it is noticeable.woodfortrees.org/plot/uah6/mean…
2/6. The problem is that aerosol/particulate pollution abatement also dates from the 1970s. CO2's forcing has rising monotonically since ≈1945, yet temperatures only started rising (in fits & starts) with the advent of air pollution abatement in the West.


The 1979 baseline temperature, against which warming is compared, was artificially depressed due to aerosol/particulate air pollution. That means subsequent warming due to GHGs is exaggerated.agupubs.onlinelibrary.wiley.com/doi/full/10.10…

@theresphysics 1/3. So, Ken, which of the facts that I mentioned in my comment on this blog post was so discomforting that it provoked you to delete the entire comment?

2/3. [Part 1 of 2]

It is refreshing to see you mention reductions in anthropogenic aerosol emissions, because most left/alarmist sources just panic,

hyperventilate,

and say we're burning up.

In fact, it is clear that aerosol / particulate air pollution abatement is responsible for some of the recent warming. Here's a paper about it:


Quaas et al (2022), Robust evidence for reversal of the trend in aerosol effective climate forcing. Atmos. Chem. Phys. Discuss. 22, 12221–12239. doi:10.5194/acp-2022-295

The significance is obvious: If a higher percentage of observed warming is due to aerosol / particulate air pollution abatement, that means a lower percentage of observed warming is due to GHGs. This is more evidence that climate sensitivity to CO2 is generally overestimated.


Here's a article about the paper:


This is Figure 1 from the paper, showing regional trends from 2000 to 2019:


Note the 2019 end date...pedestrian.tv/news/climate-c…
nbcnews.com/science/scienc…


Image
3/3. [Part 2 of 2]

...Note the 2019 end date. Subsequently, the new IMO 2020 international shipping regulations have drastically reduced aerosol emissions from ships.

The widely hyped recent spike in air and ocean temperatures is a predictable consequence.

The new regulations resulted in "an estimated 46% decrease in ship-emitted aerosols," and (because ships are a major contributor), a 10% decrease in total global sulphur dioxide (SO2) emissions. Those are very large air pollution reductions for such a short time interval. If you want to learn more about the effects of the new regulations, you can search for articles with titles like these:

● Global reduction in ship-tracks from sulfur regulations for shipping fuel

● NASA Study Finds Evidence That Fuel Regulation Reduced Air Pollution from Shipping

● Low-sulfur shipping rules are affecting global warming

It's not a problem, it's good news, because it is evidence that the pollution controls are working. It has nothing to do with carbon emissions, and it doesn't mean people need to scrap their SUVs or freeze in the dark to "save the planet."

I do hate it when people use misleading graphs to support their agendas. Now that we finally have another El Niño, plus warming from the aerosol pollution abatement, SkS can, at long last, update this one:

The claim that wind and solar energy are less expensive than electricity from dispatchable sources like fossil fuels is false. It's a product of either economic illiteracy or deliberate deception by the renewable energy marketers, because it confuses price with total cost.

You've probably heard the old saying that there's nothing more expensive than a free puppy, except a free boat. Wind and solar energy are like that: it's not their price which makes them costly.

The reason average wind and solar electricity prices are low is they tend to produce power when it is not needed. Power produced when it isn't needed fetches low prices.

But it's the converse which is the big problem with wind and solar: they very often do not produce power when it is needed.

That unreliability causes enormous spikes in electricity prices.

During those price spikes most of the electricity being produced is generated by fossil fuels and nuclear plants. Wind and solar apologists pretend that means electricity from fossil fuels and nuclear plants is expensive. But the real reason for the high prices is replacement of reliable fossil fuel and nuclear plants with unreliable wind and solar.

Exorbitant electricity prices are an inevitable cost of reliance on wind and solar for electricity.

Fossil fuel and nuclear powered electricity generation is said to be "dispatchable," because their electricity production can be ramped up ("dispatched") to meet demand. Wind & solar output cannot be ramped up to meet demand, so increased reliance on wind and solar means increasingly unreliable electricity production. When demand increases and/or the wind dies, reliance on wind and solar causes enormous spikes in the price of electricity — or, in extreme cases, even brownouts and blackouts.

The inevitable consequences of increasing reliance on wind and solar "renewables" are rising electricity prices and worsening grid reliability — and absolutely no environmental benefit.

That's right: the punch line is that it's all for naught. The rationale for the immensely destructive transition to wind and solar is to "fight climate change." But that's a fool's errand, because the "climate crisis" is a marketing ploy. It's not real, it's just "FUD."

The scientific evidence is compelling that manmade climate change is modest and benign, and CO2 emissions are highly beneficial, rather than harmful.

Does that surprise you? If so, it means you're not getting balanced information. But I'm here to help:

1/5》Lauren Witzke @LaurenWitzkeDE lies.

#1. Calling a lifesaving vaccination a "bioweapon experimental shot" is a deadly, satanic lie.

#2. Garnet Harper died of a hemorrhagic stroke while on dialysis.

Even though he was in Canada, he was NOT denied appropriate treatment.
@LaurenWitzkeDE 2/5》Garnet Harper was ineligible for transplant consideration for 2 reasons:

1. Poor health. He had severe heart & lung problems, and he'd nearly died from a staph infection.

2. His refusal to take essential steps to protect his own health, like masking and Covid vaccination.
@LaurenWitzkeDE 3/5》Because transplant recipients must be on immunosuppressants for life, it is critically important for them to take every reasonable precaution to protect against infections — and Mr. Harper had already almost died from an infection.

But he refused to take such precautions.

By now you've surely seen this figure, it was the talk of #climatetwitter today. But the most interesting part is the region I've circled. It's where Earth is constantly sliding in and out of ice ages 📉❄️📈🌲📉❄️📈🌲📉❄️
There's a paper you don't hear about very often Ganopolski-2016 that starts with Earth's orbital eccentricity, obliquity, and precession, which affect how much solar radiation the Northern hemisphere receives. Then it calculates...
...how much CO₂ is needed to boost the greenhouse effect enough to have prevented those ice ages. Turns out, ~425 ppm is pretty good estimate for "ice-age proofing" Earth.

《1/12⟫ Someone asked how we can know the ongoing rise in atmospheric CO2 level is entirely from human emissions, since Earth's climate is so complex.


Fortunately, you don't need a climate model to answer that question. It's as easy as (steps) A, B, C:sealevel.info/co2.html
《2/12⟫ A. The bean-counters keep good track of production & use of fossil fuels and Portland cement, and simple chemistry tells us how much CO2 is produced from them. That's "fossil carbon." (Irrelevant side note: fossil carbon is almost completely depleted of radioactive 14C.)
《3/12⟫ There are also "land use change emissions" (e.g., clearing forests, draining swamps), which produce non-fossil CO2 emissions. They are poorly constrained, but certainly less then 15% of fossil emissions (probably about 10%).

It looks like Twitter has made some changes to the APIs that is confusing our poor🤖. Will be suspending new unrolls until we resolve this.
We're restored most unroll services. It required quite a big change to the core unrolling services, so there are probably bugs lurking, esp. with embedded videos. But we figured it's better to get this out and fix over next few days.🙏🏼 for your patience!

@EthonRaptor @ClimateOfGavin @NASAGoddard 1/6 Eli, please tell me that YOU do not think CO2 which was FORMERLY in the air STILL has a warming effect!

I was SURE you are smarter than THAT!

Any two steadily increasing quantities correlate nicely. That doesn't mean one causes the other, of course.
@EthonRaptor @ClimateOfGavin @NASAGoddard 2/6 Our CO2 emission rate is currently about twice the rate natural sinks (terrestrial greening, ocean uptake, etc.) remove CO2. But it's mere coincidence the ratio has been near 2:1 for a quite a while. If we halved CO2 emissions the ratio would be 1:1.
@EthonRaptor @ClimateOfGavin @NASAGoddard 3/6 Coincidentally, for several decades the trend in CO2 concentration has been about half of the trend in "cumulative emissions."
But if we were to halve emissions that correlation would disappear entirely. Cumulative emissions would continue to rise, but CO2 level would not.

1/36 It's amazing how effective the Climate Industry has been at frightening people, beyond the capacity for rational thought. Rutger Bregman @rcbregman, though a smart fellow, is nevertheless "terrified" by a miniscule (≤1°C), completely harmless, sea surface temperature blip.
@rcbregman 2/ 1°C is the outdoor air temperature change ("climate change") you get from an elevation change of only about 500 feet. 🥱

(That's based on an average temperature vs. altitude "lapse rate" of 6.5°C/km; 1000 / 6.5 = 154 meters.)
@rcbregman 3/ At mid-latitudes, 1°C is about the temperature change you get from a latitude change of only 60 miles (100 km).

(How different are the flora and fauna 60 miles from where you live?)

@BradyGWilson @PaulHBeckwith 1/12》Crop yields rose in part because of CO2 fertilization.

Plus, the catastrophic, drought-triggered famines which plagued mankind for all of human history are disappearing from living memory, in part because elevated CO2 helps mitigate drought impacts.
sealevel.info/learnmore.html…
@BradyGWilson @PaulHBeckwith 2/12》Rising CO2 levels improve both crop yields and drought resistance. That's helping make famines rare for the 1st time in history.

If you're so young you don't understand how important that is, count yourself blessed! Famine used to be a scourge comparable to war & disease. Image
@BradyGWilson @PaulHBeckwith 3/12》Ending famine is a VERY Big Deal, comparable to ending war and disease. Compare:

● 1918 flu pandemic killed 2% of world population.

● WWII killed 2.7% of world population.

● The global drought & famine of 1876-78 killed 3.7% of world population.

most readers are familiar with famous "hide the decline" from Climategate. Below are 1850-2000 parts of 5 series calculated from Asian tree ring data, explained below. I recently received some fantastic PAGES2k reverse engineering from @detgodehab and am re-visiting. Image
The data illustrated below comes from
(1) original Briffa 2001 Asian series with late 20th century decline (chopped off in Mann's IPCC diagram);
(2) average of Asian series in gridded MXD series sent by Briffa/Osborn to Rutherford and Mann, ostensible input in Mann 2008
(3) average of (the 45) gridded MXD as used in Mann 2008. As discussed long ago at Climate Audit, Mann chopped off the offending declines and replaced them with temperature data. This was a different incident to the IPCC diagram or the 1999 WMO "hide the decline" diagram.

@HenrikHindby @JimFish56837379 @EcoSenseNow @DGWilkinson 1/4」This might be the study:
nber.org/papers/w29320
EXCERPT:
"We consistently find a large CO2 fertilization effect: a 1 ppm increase in CO2 equates to a 0.4%, 0.6%, 1% yield increase for corn, soybeans, and wheat, respectively.
…CO2 was the dominant driver of yield growth…"
@HenrikHindby @JimFish56837379 @EcoSenseNow @DGWilkinson 2/4」Fossil CO2 (from fossil fuels & cement) is certainly a major contributor to the huge improvement in crop yields. I'm not convinced that it accounts for a majority of the improvement, but might well have been the largest single contributor.
@HenrikHindby @JimFish56837379 @EcoSenseNow @DGWilkinson 3/4」What's more, most nitrogen fertilizer is made using fossil fuel (mostly natural gas), via the Haber-Bosch process.

Nitrogen fertilizer made using fossil fuels, plus CO2 fertilization, probably account for a majority of the improvement in crop yields.

@SchneidGabriel @cptndemocracy64 @davidcharlesuk1 @EcoSenseNow 1/7」That's simply untrue, Gabriel. Ice core records indicate that reversals in CO2 concentration trend followed reversals in temperature trend by at least several hundred years over ONE particular period of time. But that's no longer the case, and it hasn't been for >100 years.
@SchneidGabriel @cptndemocracy64 @davidcharlesuk1 @EcoSenseNow 2/7」Earth only got ≈90 ppmv of CO2 level change over a complete glaciation/deglaciation cycle, accompanied by at least 5-6°C global temperature change.
In contrast, we've gotten a 140 ppmv CO2 increase since 1780, accompanied by a small fraction of that much temperature change.
@SchneidGabriel @cptndemocracy64 @davidcharlesuk1 @EcoSenseNow 3/7」I do not understand how anyone can think that adding something to the atmosphere does not increase then amount of it in the atmosphere. That's just silly.

1 ppmv CO2 = 7.8024 Gt CO2 = 2.12940 PgC

So adding 7.8 Gt CO2 to the air raises CO2 level by 1 ppmv.

@MisinformNoMore @WeiZhangAtmos 1/ That's complete nonsense.

Given the constraints of limited fossil fuels, negative carbon feedbacks (which remove CO2 from the air), and logarithmically diminishing warming effect, we might eventually get as much as 1°C of additional warming from CO2. Probably less.
@MisinformNoMore @WeiZhangAtmos 2/ 1°C is the temperature change ("climate change") you get from an elevation change of about 500 feet.

@elonmusk Dear Elon @elonmusk, here are some ideas for how to improve Twitter, which I tweeted early this year:
sealevel.info/How_to_fix_twi…


Step #1. Stop shadowbanning! What good is a tweetstorm if, 30 days later, you can't find the 2nd tweet while viewing the 1st?
@elonmusk To reduce trolling, vitriol, fake news, etc. implement steps 2 + 3:

Step #2. Give all users the option of verifying/validating their non-anonymous accounts, using their real names (perhaps for a modest one-time fee, to cover the associated expense).
@elonmusk Step #3. Provide everyone the option to hide or block all anonymous/unverified accounts, except those who they follow.

@flimsin @krishgm @IPCC_CH @Channel4News Dr. Edwards, the AR6 concepts of "Transient Climate Response to cumulative CO2 emissions" (TCRE) & "Remaining Carbon Budget" (RCB) are based on the premise that, not merely does CO2 in the air cause warming, but that the mere MEMORY by Gaia, of CO2 formerly in the air, ALSO does. Image
@flimsin @krishgm @IPCC_CH @Channel4News In fact, the definition of TCRE presumes that CO2 which was once in the atmosphere, but has been removed by natural negative feedbacks like "greening" and dissolution into the oceans, still has JUST AS MUCH warming effect as CO2 which remains.

@omgnasa @Daniel_Marbella 1/8》That's incorrect, Josh.

Satellite altimetry is incapable of measuring sea-level near the shore. Comparisons between satellite altimetry and tide gauges are necessarily comparisons between measurements taken far apart from each other.

@omgnasa @Daniel_Marbella 2/8》There's been no rapid acceleration in the last 30 years. Some sites see periodic variation in sea-level trend, e.g., with AMO, but most have seen little or no long-term acceleration.

An exception is the SE USA, where the Gulf Stream skirts the coast.
@omgnasa @Daniel_Marbella 3/8》It is nonsense to claim that sea-level rise accelerated in the last 30 years, so it isn't evident in 100 year records. That is EXACTLY what quadratic regression would have detected as acceleration.

Well, his first 36 seconds (apparently learnt from scientists) was correct.

But the rest, which he called "beyond the science," culminating in his claim that "humans do not affect the level of carbon dioxide in the atmosphere," is codswallop.
2/13》Mankind currently adds about 5 ppmv/year of CO2 to the atmosphere.

Nature removes an average of about 2.5 ppmv/year of CO2 from the atmosphere.

Economic downturns, like the Covid-19 recession, reduce that 𝘀𝗹𝗶𝗴𝗵𝘁𝗹𝘆, as do CO2 emission reduction schemes…

@Ladidas7 @RightToLifeUK Of course not. If such a scenario were real, nobody I know (and no pro-life organization), would advocate causing the mother's death.

But it's not real. You just made it up. It's an excuse, not a reason.

Any such condition which could kill the mom would also kill her baby.
@Ladidas7 @RightToLifeUK The vast majority of abortions in the UK are obtained by perfectly healthy mothers, of perfectly healthy babies, in perfectly normal pregnancies. The problems driving pregnant moms to make that tragic choice are not medical, they're social & financial.

Baby boy sucking his toes:
@Ladidas7 @RightToLifeUK Pro-life Christian organizations stand ready to help pregnant mothers solve those problems, without killing their babies.

But abortion promoters want to prevent them from doing so, by stopping Christian pro-lifers from even offering that assistance to the mothers who need it.

⟦1/15⟧ It's time to put to rest the myth that CO2 emissions and manmade #ClimateChange is harmful to oceans, or to marine life.

⟦2/15⟧ There's no evidence that either the very slight warming trend or the very slight reduction in causticness of ocean surface water is in any way harmful. The worry about that is due to a Climate Industry marketing campaign, not because of scientific evidence.
⟦3/15⟧ So-called "ocean acidification" is both a red herring, and a misnomer. The oceans are alkaline (caustic), everywhere. They are not acidic, anywhere (except at some volcanic vents). Ocean chemistry ensures that seawater will never become acidic.

@cary_carytb @andresbcr51 @goddeketal @PfizerisEvil @birb_k About 8000 Americans die each day. During the vaccine rollout, about 1% of Americans got a vaccine jab each day. So you should expect about 80 of them to have died within 24 hours, purely by chance.

That's 7×80 = 560 deaths each week within 24 hours of a jab, NOT due to the jab.
@cary_carytb @andresbcr51 @goddeketal @PfizerisEvil @birb_k (Actually, because people at highest risk were being vaccinated first, especially the elderly, the number of incidental deaths, NOT due to the jabs, was probably even higher than that.)
@cary_carytb @andresbcr51 @goddeketal @PfizerisEvil @birb_k That's an approximation of "statistically expected number of deaths."

I hope it's obvious why VAERS death reports are NOT deaths from the vaccine. Only if they showed a statistically higher than expected number of adverse events or deaths would they be evidence of causation.

@Fardonn1 The U.S. political parties have not "flipped." The Republican Party is still the party which speaks up for the weak and the voiceless, and the Democrat Party is still the party which represents their oppressors: the slavery industry, the abortion industry, communist tyrants, etc.
@Fardonn1 The Democratic party was created in the late 1820s from the dissolution of the earlier "Democratic-Republican" Party, by supporters of Andrew Jackson, on a platform supporting slavery and "Indian removal."
@Fardonn1 The “Jacksonians” founded the modern “Democratic” party on January 8, 1828, with the launch of Jackson’s successful 1828 Presidential campaign against the Democratic-Republican incumbent, John Quincy Adams. Jackson’s supporters called their new party the Democratic Party.

@zoesqwilliams Zoe, the reason wind & solar have made energy unaffordable for Brits is that wind & solar make electricity capriciously, rather than when it is needed. Fossil fuels and nuclear supply energy when it is needed & of high value. Wind & solar usually don't.
theguardian.com/commentisfree/…
@zoesqwilliams Have you noticed how the wind very often dies at sunset? (If not, you're not a sailor.)

Well that's exactly when outdoor temperatures fall, commuters arrive home, EVs are plugged in, and evening meals are cooked: when there's often little wind energy, and no solar energy at all.
@zoesqwilliams Did you know that wind is actually an indirect form of solar power?

Relying on wind & solar "renewable" energy means freezing in the dark on windless winter nights… just to stop this consequence of CO2 emissions:

@schryguy @guardiannews 1/12:
The climate debate has never been whether "climate change is real." That's a strawman.

If someone pretends that's what the debate is about, they're just trying to con you.

The debate is over it's effects.

You needn't fear "melting ice caps."

There're only 2 ice sheets on Earth:

1. Antarctica averages < -40°, so it's in no danger of melting.

2. Greenland loses ice most years, but the rate is not detectably accelerating. It's equivalent to 3-4 inches of sea-level rise per…

No, not year.

Not decade, either.

It's PER CENTURY: Greenland's ice melt (the largest source of sea-level rise) causes 3-4 inches of sea-level rise per CENTURY.

@democra04254334 @Colin01170957 @GeraldKutney There's no consensus among scientists on any non-trivial point of the climate change debate.

Have you ever wondered why Doran, Cook, etc. NEVER ask in their polls whether manmade climate change is HARMFUL? They only ask if it's REAL. (Of course it is.)
@democra04254334 @Colin01170957 @GeraldKutney They don't ask if CO2 is harmful because they know if they asked THAT question they'd find no consensus. The evidence shows manmade climate change is modest & benign, and CO2 emissions are beneficial. Elevated CO2 greens the Earth & feeds her people.

@democra04254334 @Colin01170957 @GeraldKutney However, there's a strong consensus among scientists in the relevant field (which is agronomy!) that elevated levels of the "precious air fertilizer" (CO2) are highly beneficial for crops. That fact has been settled science for a century.

@GeraldKutney Gerald, the science shows that AGW is modest & benign, and CO2 emissions are very beneficial.

18 months ago you asked to see Prof. Dyson's email to me, about the benefits of rising CO2 levels for agriculture. I offered to share it, but you never replied.
@GeraldKutney Ruinous wind & solar energy boondoggles are impoverishing millions… and, as the Climategate whistleblower famously observed, poverty is a death sentence.

Great example of "renewable" disinfo, confusing cost & value:
They CLAIM wind & solar (W&S) are cheaper than dispatchable FF & nuclear power. Actually, dispatchables get high prices because they're available when prices are high — when prices are high BECAUSE W&S are unavailable.
Reliance on so-called "renewable" wind & solar (W&S) power makes electricity both unreliable and ruinously expensive. As the Climategate whistleblower famously observed, "poverty is a death sentence" — and W&S kill thousands.

@Veritatem2021 @AristotleMrs The Wegman Report was not "disgraced." No substantive faults were found in its analyses or conclusions.

The only fault found was w/r/t proper attributions:

"text from background sources was mistakenly used in the Introduction without proper reference to the original source"
@Veritatem2021 @AristotleMrs The later Yasmin et al article Computational Statistics, of which Wegman was a co-author, was not the Wegman Report. It was retracted because a "committee did find that plagiarism occurred in contextual sections of the article." No fault was found in its analysis or conclusions.
@Veritatem2021 @AristotleMrs Only someone foolish enough to swallow ThinkProgress disinformation would believe that the Wegman Report was wrong.

@ClimateOfGavin @theresphysics @aDissentient 1/7》Gavin, that graph is irrelevant to CFC's "greenhouse" effect.

The greenhouse effect is from intact CFC molecules in the troposphere, NOT due to stratospheric chlorine. Ozone-depleting stratospheric Cl is only released when CFC molecules break down.
@ClimateOfGavin @theresphysics @aDissentient 2/7》The Montreal Protocol's slow effect on stratospheric Cl is because CFCs break down VERY slowly, and THAT's what releases stratospheric Cl.

The unamended 1987 Montreal Protocol reduced CFC production & use to ZERO by 12/31/1995 (except developing countries w/ low CFC use):

@NY1 @TheEthicsGuy Scripture tells us that lies are the devil’s language [Jn 8:44], and God hates lies and loves the truth. But scripture also records rare examples of righteous lies.

Most of the time a Christian is required to simply tell the truth, or not speak at all. But there are exceptions.
@NY1 @TheEthicsGuy The classic example of a situation in which a Christian must lie, and do so convincingly, is when the SS knocks on her door, and asks, “Fräulein, are you harboring any Jews?”

She must lie because God hates murder even more than He hates lies!
@NY1 @TheEthicsGuy Arguably, another example might be when your wife asks you, “Honey, do I look fat?”

...because God not only hates lies, He also hates divorce!

@MattWalshBlog There's a reason some leftists don't like to talk about the ozone layer. It's because they don't want to talk about the 1987 "Montreal Protocol on Substances That Deplete the Ozone Layer," and its interesting role in the current #ClimateEmergency scam.
@MattWalshBlog You see, the CFCs which were banned by the Montreal Protocol are also, coincidentally, important "greenhouse gases," that help warm the Earth. Banning CFCs undercut the basis of #ClimateCrisis hype -- or it would have, if James Hansen had been honest.

@MattWalshBlog If Hansen's @NASAGISS NASA GISS team had modeled CFC emissions being drastically reduced (per the Montreal Protocol), their model wouldn't have predicted enough warming to be worrisome. So they lied: they modeled an exponential INCREASE in CFC emissions.

@JasonSCampbell 1/4》The next year, @DrJamesEHansen published his famous paper predicting 0.5°C/decade global warming from continuing "Scenario A" carbon emissions. Representing @NASAGISS, he testified to Congress that was "business as usual."

His goal was to push climate alarm & fund the IPCC.
@JasonSCampbell @DrJamesEHansen @NASAGISS 2/4》What Hansen failed to mention when he testified to Congress is that what he called "business as usual" actually pretended the Montreal Protocol had not been adopted, & assumed exponential growth in CFC emissions. THAT was the cause of most of their predicted global warming.
@JasonSCampbell @DrJamesEHansen @NASAGISS 3/4》It worked. The IPCC was created in 1988, and Congress approved funding.
But thanks to the Montreal Protocol, CFC emissions declined drastically (as Hansen & GISS knew they would). So we got less than 1/3 of the warming GISS had dishonestly predicted.

No responsible journalist would print an accusation without giving the accused party an opportunity to respond. But that's apparently what TIME did.
@amanbatheja @TIME 3/6》𝗕. The accusation is anonymous hearsay. TIME identified the accuser only by her first name, and coyly couched the accusation with, "Ashley says…" That way, when accused of lying, they can offer the defense, "WE didn't accuse them, we just reported what someone ELSE said."

@AndrewDessler Droughts are WORSE with low CO2. The 1876-78 global drought & famine killed ≈3.7% of world population! Thankfully, elevated CO2 mitigates drought impacts by making plants more drought resilient, thru reduced stomatal conductance.



sealevel.info/learnmore.html…
@AndrewDessler The fact that elevated CO2 makes crops more water-efficient and drought resilient, by reducing stomatal conductance, is well-established. The effect has been measured by many rigorous studies. E.g.
sciencedirect.com/science/articl…
@AndrewDessler That's why thousands of studies have found that under dry conditions elevated CO2 (eCO2) is especially beneficial, for ALL important crops.

eCO2 also beneficial under other conditions, but it is ESPECIALLY beneficial under dry conditions.

sealevel.info/learnmore.html…
2/12》When IPCC says we must prevent global warming from exceeding "1.5°C" they don't really mean that. They mean 1.5° warmer than the chilly Little Ice Age, which they guesstimate was roughly 1.1°C colder than now. (Nobody really knows!)
So they really mean 0.4°C of warming.
3/12》When the IPCC claims that ">2°C" would be catastrophic, they don't really mean 2°, either. They mean 2° warmer than the guesstimated temperature of the chilly LIA, so when they say "2°C" they really mean a mere 0.9°C warmer than now.

How mRNA vaccines work, oversimplified:
It's a mRNA string that instructs yr own cells to create a spike protein that is highly similar to the spike protein outside the SARS-COV-2 virus. This is the new part. The mRNA is gone in hours, & the spike proteins are gone in days.
1/?
Yr immune system sees the spike proteins, & develops immunity to them. That's the part that's like any other vaccine (& a lot like any actual infection too).
Later on, if & when yr immune system sees SARS-COV-2 spikes, it attacks. That's how all acquired immunity works.
2/?
How it's different from other vaccines: having yr own cell build the antigen, instead of having it injected (or in some cases swallowed). That's all that's different. And remember, building things according to mRNA instructions is what cells do.

@gulfsouthtiger JD, you're right about Obama & the TX massacre but wrong about this.

@gulfsouthtiger The vast majority of Covid-19 case in children are mild. But vaccination of children still reduces their risks:

A: Because of LIFE!

All life on planet Earth is carbon-based. The carbon is from CO2 in the air. Carbon-hungry living things used up nearly all of it, harvesting carbon and releasing oxygen as waste.
2/14》Every schoolchild learns that animals use O2 (oxygen) and produce CO2 (carbon dioxide), and plants do the opposite. But have you ever wondered why there are about five hundred O2 molecules in the Earth’s atmosphere for each CO2 molecule?
3/14》On Venus and Mars it's the other way around. On those planets, nearly all of the oxygen in the atmosphere is in the form of CO2, and almost none is O2.

But on Earth O2 is 21% of the atmosphere, and CO2 is only 0.04%.

Q: Do you know why?

But it's really even less than that.

Russia proper (not counting Kaliningrad Oblast) is bordered by 12 countries, only three of which are NATO members (Estonia, Latvia & Norway).
@FrankRGardner 2/4》In alphabetical order they are: Azerbaijan, Belarus, China, Estonia, Finland, Georgia, Kazakhstan, North Korea, Latvia, Mongolia, Norway, and Ukraine.

Additionally, Kaliningrad Oblast is bordered by Poland and Lithuania, which are NATO members.

CPAC claims to be the largest annual gathering of conservatives in the nation.

I’ve always been happy that #CPAC included the discussion of abortion and prolife speakers, and have spoken twice at the conference. Once pregnant and once as a new mom.
I have served on the Social and Cultural Planning Committee for CPAC, where a small group of leaders meets to compile topic and speaker ideas and submit them to CPAC. These always seemed to be considered and many accepted.

But not this year.
Oddly, this year, not a single speaker or session focused on abortion.

Not one on the threat to women's sports

Not one on religious liberty

Not one on family, marriage, sex trafficking, pornography, etc...

@realBockmann 1/7》Nor are abortion rates as high or higher WHEN abortion is restricted.

It's just the opposite: U.S. experience proves that legalizing abortion greatly increases the number of abortions. It hardens hearts to the plight of the unborn, making abortion more socially acceptable.
@realBockmann 2/7》Over the decade following Roe v. Wade, as abortion gained acceptance, the U.S. abortion rate more than doubled. From 1972 to 1981 the number of abortions nearly tripled (586,800 → 1,577,300), and the abortion rate (per no. women of childbearing age) increased 122%.
@realBockmann 3/7》Unsurprisingly, a sharp increase in abortions & a sharp drop in birth rate immediately followed the 1973 Roe v. Wade decision. But then a strange thing happened: abortion rate continued to increase, as acceptance of abortion increased. But the birth rate increased as well.

@rahmstorf Fire trends are dominated by land management practices, and little affected by climate change. So climate change can't be blamed for Australia's current fires, nor credited for the global improvement.

CO2 & climate change certainly doesn't cause arson:
amp.brisbanetimes.com.au/national/queen…
@rahmstorf NASA measures fire trends by satellite:

earthobservatory.nasa.gov/images/145421/…

earthobservatory.nasa.gov/images/90493/r…

"...MODIS [satellite instruments have measured] a decrease in the total number of square kilometers burned each year. Between 2003 and 2019, that number has dropped by roughly 25%."
@rahmstorf Blaming fires on climate change is "cargo cult science." Fire severity depends mostly on land mgt practices, not air temperatures. Worst fire in US history was in chilly Wisconsin in October, 1871, when CO2 (estimated from ice cores) was only ≈288 ppmv.

@RARohde @wennbergcaltech 1/8》The temperature changes in question are so miniscule they're hard to measure, hence the inconsistencies.

An advantage of satellite temp measurements is their near-global coverage. They measure lower troposphere air temperatures by consistent means, over both land & ocean.
@RARohde @wennbergcaltech 2/8》"Surface temperatures" conflate two quite different kinds of measurements:

1. AIR temperatures, measured in instrument enclosures 1.25-2.0 meters above the ground.

2. Sea-surface WATER temperatures, at varying near-surface depths.
@RARohde @wennbergcaltech 3/8》The best satellite dataset is UAH 6. They're the scientists who pioneered & refined the methods that RSS uses. Here's why UAH is better than RSS:

@thelindscape @skdh @sciam @NASAGoddard @NASAGoddardPix 2/21》Lindsey, you wrote, "CO2 does act as a fertilizer, but only to a certain extent."

That's technically true, but wrong for practical purposes, because the "CO2 fertilization" benefit of rising CO2 level doesn't begin to taper off until about 1000 ppmv.
@thelindscape @skdh @sciam @NASAGoddard @NASAGoddardPix 3/21》That's far higher than we can ever hope to drive CO2 levels. So for practical purposes, the "fertilization" benefit of rising CO2 levels is approximately linear, and it's been measured by many rigorous studies:

Vancouver Coastal Health (VCH) is aware of rumours and disinformation spreading on social media regarding stillbirths at Lions Gate Hospital (LGH) as a result of mothers having been vaccinated against COVID-19.

Thread:
1: There is no truth to this claim and the individuals spreading this false information have no affiliation to either LGH or VCH. There has been no notable change to the incidence of stillbirths in the VCH region throughout the COVID-19 pandemic.
2: This type of disinformation adds unnecessary stress to expecting parents who have received a COVID-19 vaccine, on health-care staff who must reassure their patients, and on the health-care system, as resources are stretched further during the ongoing pandemic response.

@johananderberg @unherd Sweden relied more heavily on voluntary measures than other Scandinavian countries did, and, unfortunately, they paid a heavy price for it. Their death rate from Covid-19 was MUCH WORSE than neighboring countries, and 5.4× worse than those countries' average Covid-19 death rates.
@johananderberg @unherd Most Eastern European countries did even worse than Sweden, as did the United States and a few other Western European countries. But that certainly doesn't mean Sweden did well. The Swedish experiment was a disaster.
@johananderberg @unherd These figures for Sweden & neighbors are from Sept:

Norway:
850 deaths / 5,473,010 population = .016%

Finland:
1062 / 5,551,240 = .019%

Denmark:
2,634 / 5,817,126 = .045%

Sweden:
14,767 / 10,176,187 = .145%

@dperetti One the anti-vax scammers' favorite lies is the claim that Covid-19 vaccines have killed thousands of people. They haven't. Here are links to two different debunkings of that lie:
sealevel.info/covid.html#vae…
@dperetti On an average day, in the developed world, about 0.0023% of any randomly chosen population dies.

In the USA, that works out to about 7,500 deaths per day. In other words, if you pick an American at random, there's about a 0.0023% chance that he or she will die within 24 hours.
@dperetti So far, about 7 billion Covid-19 vaccine jabs have been given, globally. 0.0023% of that is 161,000.

Americans got 411 million jabs (I got 3). 0.0023% of 411M is 9,453.

Those are estimates of number of COINCIDENTAL deaths within ONE DAY of getting a jab, NOT caused by the jab.

@arynebaker 3/47》However, this part of what you wrote is not true: "The loss of land based glaciers and ice shelves, however, has serious consequences."

Ice shelves are floating ice, just like sea ice. Consequently, they do not affect sea-level when they melt.

@irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp There are no "increased stressors on crops" due to climate change. Neither droughts nor wildfire incidence have worsened. Wildfires incidence has everything to do with land management practices, and nothing at all to do with climate change.

@irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp Here's what's happened to crop yields as CO2 levels have risen. Only part of the improvement is due to rising CO2 levels, but it is a significant part:
@irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp Blaming fires on climate change is "Cargo Cult Science." There is no scientific basis for it. Man-made climate change does not significantly affect the risk or severity of fires. Fire severity depends mostly on land management practices, not air temperatures.

@irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp Impact of climate change on coastal sea-level trends is near zero. The "global"[sic] trend is so slight that in many places it's exceeded by local factors, like erosion, sedimentation & vertical land motion. Greta's hometown of Stockholm is one such place.
sealevel.info/MSL_graph.php?…
@irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp If "global" sea-level rise accelerated, it would help with Stockholm's dredging expense.

dredgingtoday.com/2014/03/07/swe…

Unfortunately for Stockholm, there's been no significant reduction in the rate of sea-level decline there.
@irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp The only really significant effects of manmade climate change are the large improvements in crop yields due to CO2 fertilization, and the mitigation of drought impacts, because eCO2 makes plants more water-efficient & drought-resistant.

@OkeeffeLynn @irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp That's a convenient place for such fanciful modeling, because there are no long, high-quality sea-level measurement data from Ireland's west coast.
The best measurements show that climate change has not significantly affected sea-level trends. E.g.,
sealevel.info/MSL_graph.php?…
@OkeeffeLynn @irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp In fact, ALL the supposed major harms from manmade climate change, such as greatly accelerated sea-level trends, are merely hypothetical. They aren't actually happening, and there's no reason to suppose they ever will.

@OkeeffeLynn @irish2witter @climpeter @IPCC_CH @mpclimate @bobkopp Contrary to the hysteria, there's no evidence manmade climate change is harmful. In fact, scientists call warm periods "climate optimums." The best SCIENTIFIC evidence is that manmade climate change is modest & benign, and CO2 emissions are beneficial.

@climpeter @IPCC_CH @mpclimate @bobkopp Meanwhile, in the real world, despite +108 ppmv (+35%) CO2 and +0.839 ppmv (+81%) CH4 increases, sea-level trends at most of the highest-quality long-term measurement sites haven't changed significantly in 9 decades, averaging just 6 inch/century.

@j_malhocarvalho @Trouble91775621 @DoomsdayDebunks @nytimes That's wrong. You've confused death AFTER vaccination with death FROM vaccination.

≈0.016% of any random population die each week, of all causes. Portuguese got 17.5 million jabs. So you should expect ≈2800 Portuguese to have died of UNRELATED causes within 1 week of a jab.
@j_malhocarvalho @Trouble91775621 @DoomsdayDebunks @nytimes The report makes it clear that they do NOT blame vaccination. Page 7 says:

"Os casos de morte ocorreram num grupo de indivíduos com uma mediana de idades de 77 anos e não pressupõem necessariamente a existência de uma relação causal entre cada óbito e a vacina administrada, …

I've been talking about ivermectin a bit recently, and every time I mention it someone will link me to this odd website - ivmmeta dot com

So, a bit of a review. I think this falls pretty solidly into the category of pseudoscience 1/n Image
2/n The semi-anonymous site claims to be a "real-time meta analysis" of all published studies on ivermectin, collating an impressive 60 pieces of research

It's flashy, well-designed, and at face value appears very legitimate
3/n The benefits that this website show for ivermectin are pretty amazing - 96%(!) lower mortality based on 10,797 patients worth of data is quite astonishing. Sounds like we should all be using ivermectin!

Except, well, these numbers are totally meaningless Image

1. It's a bit of a strawman, and

@Jeremy_Williams It's NOT new, and NOT due to "climate change."

The solution is to bring them food. Fortunately, the world has plenty of food. One of the reasons is eCO2. ≈15% of current crop yields are attributable to elevated CO2 levels, a fringe benefit of fossil fuel use & cement production
@Jeremy_Williams The problem is that reporting like this, which falsely claims that the drought is unprecedented, and that "climate change" is to blame, misleads people into thinking that we need to reduce CO2 emissions to prevent famines. That is the OPPOSITE of the truth.
@Jeremy_Williams Now, you haven't answered my question:

Did you KNOW the reason Madagascar hasn't been classified "Phase 5" before is that the classifications weren't created until 2004?

Was that misleading omission deliberate, or because you didn't know about it?

629,842 deaths from (29,712,230 reported + 46,400,000 unreported + 629,842) resolved cases = a true Infection Fatality Rate (IFR) just under 1% (0.82%).

@BerkeleyEarth [1/11] BEST's figures imply MUCH LOWER climate sensitivity than IPCC claims.

You show, "About 2.3°C of warming per doubling of CO2 (ignoring the role of other greenhouse gases and forcings)."

But to deduce climate sensitivity (to CO2), you CANNOT ignore other GHGs.
[cont'd]
@BerkeleyEarth [2/11] Even if we assume that none of the warming is natural, if 30% of the warming is due to increases in minor GHGs like O3, CH4, N2O & CFCs, then "climate sensitivity" from a doubling of CO2, according to BEST's figures, is only 0.7 × 2.3 = 1.6°C.
[cont'd]
@BerkeleyEarth [3/11] That's a "practical estimate" of climate sensitivity, from surface station measurements. However, if the best satellite data were used, instead of BEST's surface temperatures, sensitivity would be almost 30% lower:

@Jeremy_Williams @NatGeo @newscientist That's wrong, Jeremy. Do you imagine that droughts are something new? Do you know how it was that the Israelites ended up in bondage, in Egypt?

NOW most famines are caused by conflict. But when CO2 levels were <300 ppmv most famines were caused by drought.
@Jeremy_Williams @NatGeo @newscientist When you read that "Madagascar is going through its worst drought in 40 years," you should realize that means they had an EVEN WORSE drought back when CO2 level was only about 340 ppmv (75 ppmv lower than now).

@TalusDice @EcoSenseNow Actual warming is so slight it's very hard to measure, and much of that reported slight warming is from revising / "homogenizing" old data.

@Tony__Heller @B_Bolshevik100 @GretaThunberg The global average coastal sea-level trend, from the highest-quality measurement records, is about +1½ mm/year (≈ 6 inches/century).

@OurWorldInData @Nature @80000Hours @robertwiblin @MaxCRoser @MaxCRoser, I think it is ironic that you discussed how poorly "we counted" (by which you mean that OTHER people counted), when the @OurWorldInData team doesn't actually seem to know what what the word "counted" means.
@OurWorldInData @Nature @80000Hours @robertwiblin @MaxCRoser Will you please rewrite this gibberish into intelligible, unambiguous English?
ourworldindata.org/grapher/covid-…

"COVID-19 vaccine doses administered per 100 people"
@OurWorldInData @Nature @80000Hours @robertwiblin @MaxCRoser "Total number of vaccination doses administered per 100 people in the total population. This [WHAT?] is counted as a single dose, and may not equal the total number of people vaccinated, depending on the specific dose regime (e.g. people receive multiple doses)."

@mdc_martinus 1/5 In 1896, CO2 leve was a proxy for a host of airborne contaminants, from people (breathing/sweating/etc), and also indoor combustion, for lighting, heating & cooking.
sealevel.info/resources.html…
CO2, by itself, is harmless to far higher concentrations:
nap.edu/read/11170/cha…
@mdc_martinus 2/5 Numerous studies have found that CO2 levels elevated to more than 8x the current average out­door level of 415 ppmv (0.0415%) are harm­less to humans & animals. NASA kept the at­mos­phere in the Space Shuttle at about 5000 ppmv (0.5%) CO2.

@mdc_martinus 3/5 The air in the Inter­na­tional Space Station is kept at about 4 mm Hg = 5400 ppmv (0.54%) CO2, though one study rec­o­mmends that they lower that to 2.5 mm Hg = 3300 ppmv.

Engineers (and systems scientists, who are really engineers) are the people who analyze feedback systems, so they're excellent people to ask. Burt's ppt is superb, and you could learn a lot from it, if you took the time.

@BrknMan @KCTaz @chimera414 @rattibha @CarlaSpade @nvangelder03 @IngersolRobert @Kenneth72712993 @Tokyo_Tom @O 2/4. Unfortunately, volcanoes de-sequester CO2 only very slowly, and there's evidence that they do so even slower during glaciations:

Here's a paper:

@BrknMan @KCTaz @chimera414 @rattibha @CarlaSpade @nvangelder03 @IngersolRobert @Kenneth72712993 @Tokyo_Tom @O 3/4. You're correct that natural negative feedbacks regulate CO2 levels, and they're the reason CO2 levels bottom out during glaciations, instead of falling below about 180 ppmv. But the main way that feedback works is by killing plants, as Burt described.

@KeillerDon @DanCady @GeraldKutney @Cambridge_Uni 1/6. That's mostly correct, @DanCady, but:

1. It's a bit of a strawman, and

2. It's also a lot more complicated than that.

It's a strawman because the climate debate is about whether global warming is harmful or helpful, not whether it's real.

quora.com/Did-30-000-sci…
@KeillerDon @DanCady @GeraldKutney @Cambridge_Uni 2/6. It's more complicated than that because, for example, Feldman's measurements indicate that CO2's radiative forcing is substantially less than what is assumed in most climate models:

@KeillerDon @DanCady @GeraldKutney @Cambridge_Uni 3/6. Additionally, measurements show that "climate sensitivity" to increased CO2 concentration is considerably less than what is assumed in most climate models.

The Paris Climate Accords is an immoral, self-destructive agreement that on paper commits the US to huge productivity losses in the short term and total economic destruction in the long term. Unfortunately, Joe Biden’s plan to implement the Paris Accords is far worse.

THREAD
In 2015 the Obama/Biden administration, without Senate authorization, committed the US to the Paris Climate Accords. The Accords called for a 28% cut in emissions by 2025 and at least an 80% cut by 2050.
The costs of Obama's Paris plan would have been enormous. The nonpartisan National Economic Research Associates concluded that Obama's plan would cause rising economic damage reaching $2 trillion a year—about $15,000 a household—by 2040.

@dfreedman7 That's true, but it is far from the only example, and there's no law of nature which ensures that such crackpots must remain in the minority. Sometimes they don't. Quite a few entire academic fields are now dominated by such crackpottery.
@dfreedman7 Another example is climatology. The scientific evidence indicates manmade climate change is modest & benign, and CO2 emissions are beneficial. The major harms are all hypothetical & mostly implausible; the major benefits are proven, measured & very large.
@dfreedman7 But in some supposedly-scientific circles, it is heresy to admit such things. The "climate catastrophe" has become as much an irrational article of faith for them as the irrational belief that the coronavirus vaccine alters people's DNA is for pharmacist Steven Brandenburg.

@CavistonJoe It was a paraphrase, not a quote. Lara Trump compressed Lincoln's 148 words down to just 22, but her paraphrase nevertheless accurately reflected Lincoln's meaning.

So what? Her speech was only 1/3 the length of Lincoln's, so she had to be concise. Brevity is the soul of wit.
@CavistonJoe It would have been better if Lara had said, "Paraphrasing Lincoln," instead of "Lincoln said." Big deal.

How ironic that Democrats, who lie outrageously about nearly everything, fuss about THAT… and on TWITTER!

@IBergwiesel @Dardedar @rahmstorf @IngersolRobert 1/6 Most plants don't get water from the air, they get it from the soil. Lower humidity is associated with lower plant growth rates, but that's because it is correlated with soil moisture levels, and lower plant growth rates reduce transpiration, thereby reducing humidity.
@IBergwiesel @Dardedar @rahmstorf @IngersolRobert 2/6 As atmospheric CO2 levels increase, plants' water requirements decrease, due to the reduced stomatal conductance & transpiration needed to absorb CO2 from the air. So if CO2 levels rise you can get reduced transpiration and thus reduced humidity WITHOUT slowing plant growth.

@DrDavidKatz 1/18 Sweden's approach is catastrophic failure. They're nowhere near "herd immunity." They're doing even worse than USA. Here're their stats:

Sweden population = 10.3 million. Do the math: Sweden per-capita CV-19 death toll to date is 38% worse than USA.
@DrDavidKatz 2/18 CV-19 has best case fatality rate ≥2.5%. That's the rate in S.Korea, where they identify infections early, via intensive testing and contact tracing. In most other countries, including the USA, diagnosis is usually tardy, & fatality rate is worse.

@DrDavidKatz 3/18 A 2.5% fatality rate is about 20x as deadly as the typical seasonal flu.

Do the math: 2.5% of 90% of 11.3 million = 1/4 million dead Swedes.

@andrewbostom @AlexBerenson @inschool4life @Alex_Washburne 3/8 Twenty-eight million U.S. cases would be an 8.5% infection rate. If that many Americans had really been infected, then nearly everyone would have been exposed by now. There would be no remaining large populations free of the disease.

@dan613 Hansen was talking nonsense. Remarkably, he'd apparently never heard of Arctic Amplification.

CO2-driven warming warms high latitudes (both SST & air) MORE (not less) than low latitudes.
@dan613 Hansen said that the “increasing temperature gradient" [between high & low latitudes] "is going to drive stronger storms,” as lower latitudes warm faster than higher latitudes. But even then it was common knowledge that exactly the opposite was true.
@dan613 He was 100% wrong. In n. hemisphere Arctic amplification warms high latitudes faster, and stabilizing negative feedbacks reduce warming in the tropics. So anthropogenic climate change causes a REDUCED temperature gradient, rather than increased.

@gunsnrosesgirl3 In 2011 Dr. Peter Gleick was the climate movement's top ethicist: Chairman of @theAGU's Task Force on Scientific Ethics. While Chairman he hatched a scheme to smear a free-market think tank, Chicago's @HeartlandInst, because they oppose climate alarmism.

tinyurl.com/fakegate
@gunsnrosesgirl3 @theAGU @HeartlandInst 1st Gleick committed identity theft, impersonating a Heartland Board Member to steal internal info. Then he forged a fake Heartland "confidential strategy memo," full of fictional evil plotting, & sprinkled with info he took from the stolen documents, to make it seem authentic.
@gunsnrosesgirl3 @theAGU @HeartlandInst Then, on Feb. 14, 2012 Gleick "leaked" the forgery (and the stolen real documents) to the press, via DeSmogBlog, while posing as an anonymous "Heartland insider."

@ClimateOpp [1/14] @ClimateOpp why did you tell @jdickerson & @60minutes that "sea level rise is accelerating," when all the best long measurement records show that coastal sea-levels trends have NOT significantly accelerated in >90 years?
sealevel.info/MSL_graph.php?…
@ClimateOpp @jdickerson @60Minutes [2/14] The Dutch, for obvious reasons, have been paying close attention to sea-level for a very long time. Their measurements show that there's been no significant acceleration in rate of sea-level rise in response to rising CO2 levels:
@ClimateOpp @jdickerson @60Minutes [3/14] Venice is one of the very few sites which have measured a statistically significant change in rate of sea-level rise: it DECELERATED slightly (probably because they curtailed groundwater pumping in the 1980s, to reduce subsidence).

@rahmstorf Fire trends are dominated by land management practices, and little affected by climate change. So climate change can't be blamed for Australia's current fires, nor credited for the global improvement.

CO2 & climate change certainly doesn't cause arson:
amp.brisbanetimes.com.au/national/queen…
@rahmstorf NASA measures fire trends by satellite:

earthobservatory.nasa.gov/images/145421/…

earthobservatory.nasa.gov/images/90493/r…

"...MODIS [satellite instruments have measured] a decrease in the total number of square kilometers burned each year. Between 2003 and 2019, that number has dropped by roughly 25%."
@rahmstorf Blaming fires on climate change is "cargo cult science." Fire severity depends mostly on land mgt practices, not air temperatures. Worst fire in US history was in chilly Wisconsin in October, 1871, when CO2 (estimated from ice cores) was only ≈288 ppmv.

@MonkeyMyBack @wattsupwiththat DeSmogBlog is a disinformation site.

Its founders were funded with “dirty money” from convicted Internet gambling felon John Lefebvre:
telegraph.co.uk/finance/market…
@MonkeyMyBack @wattsupwiththat DeSmog's co-founder, Ross Gelbspan, is a scam artist who intermittently claims to have won a Pulitzer Prize. He didn't. He once worked at Boston Globe. Other reporters there won the Prize, but he didn't. He thinks he should have shared their Prize, so he just pretends he did.
@MonkeyMyBack @wattsupwiththat DeSmogBlog even conspired with Peter Gleick to disseminate Gleick's forged "policy memo," smearing Heartland Institute:

@AndrewDessler I have four questions for you, @AndrewDessler.

1. When did it become acceptable to blame ARSON on climate change?

@AndrewDessler 3. How do you value a GREENER Earth?

@JustinHGillis Mr. Gillis, do you CARE about truth? Your @nytimes "what is climate change" page is misleading readers w/ FALSE claim that sea-level rise has accelerated. ALL highest-quality long measurement records show same LACK of significant acceleration.

nytimes.com/interactive/20… Image
@JustinHGillis @nytimes Of course, @JustinHGillis and @nytimes never replied, and didn't correct the misinformation. ∴ we can conclude that they're willing to mislead readers, if necessary to promote the agenda.

@ReutersAfrica [1/4] @winning_alex, @AfDB_Group has decided to sacrifice African lives to support the parasitic "renewables" industry. The consequence will be permanent poverty & shortened lives for hundreds of millions of Africans, with NO environmental benefit.
wattsupwiththat.com/2019/12/29/cli…
@ReutersAfrica @winning_alex @AfDB_Group [2/4] Don't be fooled by claims that the human costs of "climate mitigation" are good for "the planet." The best scientific evidence is that manmade climate change is modest & benign, and CO2 emissions are beneficial, rather than harmful. Learn more here:
sealevel.info/learnmore.html
@ReutersAfrica @winning_alex @AfDB_Group [3/4] Climate alarmism is not based on science, it is the product of superstition and the cynical propaganda & political machinations of the parasitic $1.5 trillion climate industry. To get this decision, they probably bribed key @AfDB_Group leaders, like @akin_adesina.

@MayaEarls @chelseaeharvey [1️⃣ of 1️⃣6️⃣] @hausfath's study is nothing but spin. To excuse EXTREME inaccuracies of modeled projections that failed to anticipate negative feedbacks would mitigate GHG emissions, he substituted GHG level increases AFTER the effects of negative feedbacks, in place of emissions.
@MayaEarls @chelseaeharvey @hausfath [2️⃣] The studies which @hausfath claims were accurate were actually wildly INACCURATE, in part because they failed to anticipate how negative CO2 feedbacks like terrestrial greening and ocean processes would remove much of the anthropogenic CO2, mitigating its effect on climate.
@MayaEarls @chelseaeharvey @hausfath [3️⃣] Here's Hansen et al 1988, reporting the results of GISS Model II. They projected +0.5°C/decade for their "Scenario A." (Oddly, their own graph showed only 0.37°C/decade, but the reviewers & editors apparently overlooked that inconsistency.)

@keithboykin Actually, the lynchings happened because of Democrats. Republicans never lynched anyone, it was all Democrats.

The Republican Party was founded in 1854 by Christian abolitionists, to emancipate the slaves, i.e., to free the oppressed from their oppression.
@keithboykin The GOP's heritage is the Party of individual liberty, the Party of Christian morality, and the Party which gives voice to the voiceless, such as slaves, and unborn babies.
@keithboykin The Democratic Party was founded in 1828 by supporters of Andrew Jackson, on the twin pillars of slavery and Indian Removal

@DavidRouxel1 @RoctexterNY @IPCC_CH Global sea-level rise is so slow that in many places it's dwarfed by local factors, like erosion, sedimentation, and vertical land motion. That's why some places have sea-level trends like this:

sealevel.info/MSL_graph.php?…
@DavidRouxel1 @RoctexterNY @IPCC_CH Some people mistakenly suppose AGW must accelerate sea-level rise, because it causes thermal expansion & melts ice. But they ignore the fact that AGW also increases snowfall on ice sheets & glaciers (an offsetting effect, lowering SL).

It does so through 2 distinct mechanisms:
@DavidRouxel1 @RoctexterNY @IPCC_CH 1. Warmer air carries more moisture. Below freezing, it's 8-12% more moisture per 1°C of warming. (That's why heaviest blizzards occur when temperatures are only moderately below freezing.)
