    Jacek,
       My name does appear to be down as convenor for CL20.  I am not at the moment planning
    to go. I suggest you contact the other two convenors Wolf-Christian Dullo and Jean Jouzel
    as one of them may be going.
    Cheers
    Phil

     HI Jacek,
     I'm not involved in the organization of the session next year. I don't think Phil Jones
     is either, but I'm copying this message to Phil to check--there appears to be a mistake
     in the program. You should check w/ the other conveners of the session,

     Dear Michael:
     I have noticed that Jones et al (including you) are organizing a session on paleoclimate
     in Viena next spring.
     I wrote an email to all of you CConvenors asking if the paper on regional gst history
     variations from well temp. inversion would fit in.
     I have never seen any response. Has my email ever got through?
     Best regards

          Dear Jacek,
          Thanks very much for sending this. I had a chance to read it over, and it is very
          interesting--I like the fact that you've extended the estimates back over 1000
          years, not just back 500 years (as in the papers by Huang and Pollack). This
          provides a longer perspective on the recent GST warmth, and some some nice
          independent confirmation of the basic conclusions from other (proxy and model)
          evidence that late 20th century warmth is anomalous in at least a millennial context
          (specifically, in the Arctic region in your analysis).
          Incidentally, Phil Jones and I published a review paper in "Reviews of Geophysics"
          earlier this year which provides a pretty up-to-date comparison of the various
          proxy-based reconstructions and model simulations on this timeframe:
          Jones, P.D., Mann, M.E., [4]Climate Over Past Millennia, Reviews of Geophysics, 42,
          RG2002, doi: 10.1029/2003RG000143, 2004.
          [5]ftp://holocene.evsc.virginia.edu/pub/mann/JonesMannROG04.pdf
          I would encourage you to send the paper you sent me to Phil Jones
          (p.jones@uea.ac.uk) and Jonathan Overpeck (jto@u.arizona.edu). They will lead
          authors on the chapters dealing with these issues in the next IPCC report, and I
          believe that the authors of the report would find your results very useful.
          Best regards,
          Mike

          Do you recall any 20th century N. America warming map which one could use to compare
          with GST warming (based on well data)?
          Also, 19-20th century would do.
          I have a review paper into Reviews into Geophysics going.

          I will appreciate any suggestions,

          Attached are some n. wells interpretation.
          I am attaching proofs so the corrections (like spelling of my name is wrong) are
          pending.
          Hope that this will be of interest. I did refer to your work questioning some of the
          GST SAT tracking in the northern climates.

                HI,
                Thanks for your message Jacek, and for the reprint. I'll look forward to
                reading it as soon as I have the chance.
                Re your comment, well I  don't believe there is any reason for the fluxes to
                balance out on decadal timescale or any other timescale, because this isn't
                really a latent issue effect at all, its an issue of the incoming radiation
                budget influence the air and ground. The ground doesn't "see"  much of the
                cold winter air cooling in the presence of snow cover because of insulation
                and reflection of incoming radiation. So the ground never knows about the
                negative atmospheric cooling that existed above the snow layer. This amounts
                to a rectification of the seasonal temperature signal, and a loss of
                information about the extent of winter cooling. Imagine a perfect insulator
                between ground and air. It wouldn't matter to the ground if air temperatures
                cooled 1 degree C or 10 degrees C, as long as the ground was insulated. So its
                an issue of potential loss of information of cold-season temperature
                variations.
                Our model analysis bears that out, and I think that Tinjung Zhangs' work is
                showing the same thing in Eurasian soil temperature measurements. Anyway, will
                be interesting to continue to discuss.

                Dear Dr. Mann:
                attached is my paper on the polish history of gst vs. sat . these ones show
                good agreement unlike in Canada.
                Poland is also a country with variable snow cover like Canada. on the other
                hand any major land clearing went through the area in the 15th-18th century so
                that signal of step like temperature jump is not as significant in the
                inversion process as in the Canadian situation where some of permanent land
                change is only half a century old!

                p.s. read with interest your grl paper. i am still not sure about the
                influence of freezing -thawing process and latent heat effects. it is true
                that ground stays at near 0 C when frozen despite much wilder surface
                temperature changes; however in the anuual deacadal scale shouldnt it all be
                reflected in the equality of fluxes. while heat is released when moist ground
                freezes it is taken from the environment when it thaws in the spring. so, on
                the annual/decadal scale wouldnt these two effects reflect some balance
                allowing us good judgment on the long term increases or decreases of ground
                temperature as seen by our well temperature inversion ?
                p.s. my story on the north i have presented in nice is now in revision for
                pure and applied geophysics.  Lachenbruch's Alaska data inversion is quite
                different from the canadian north . first one (as  noticed by Lachenbruch in
                his classic paper in science) shows quite late onset of surface warming(20th
                century). it seems to be much earlier in the Canadian north (arctic islands
                etc). variability of the warming onset time was also noticed in my 2002
                October jgr red paper .

                      Hi Jacek,
                      Thanks for your message--yes, I too was disappointed that the discussion
                      was not broader--I think that it was a bit of a setup by Hugo to debate
                      our latest work--perhaps that was useful, but it also didn't lead to a
                      very inclusive discussion, and that would have been more helpful from a
                      scientific point of view.
                      your new results sound very interesting indeed, and i look forward to
                      hearing more about them.
                      you can find a reprint of our JGR paper (and also a preprint of my GRL
                      paper w/ Gavin Schmidt modeling GST and SAT differences) here (as

                      the discussion in nice France was really exciting. unfortunately my
                      paper on the northern arctic wells did not get any discussion at all and
                      I hope that it was just a result that it came last and people were
                      tired.
                      I have some funding to expend my work on influence of land change on
                      subsurface temperature in time and derived gsth into whole of Canada.
                      other examples include Cuba where depleting jungle for sugar cane
                      plantation had effect. some of gst warming derived from well
                      temperatures are some 4-5 deg. C!!.
