Happy New Year Stefan and Fortunat - just wanted to check in to see 
where things stand with the EMIC runs you were going to do for the 
revised Fig 6.10 - that is, with the new Lean solar forcing, and 
(where the published runs don't already exist) with the old Lean 
forcing. Again, the purpose of all this is to assess what difference 
the new solar forcing makes.

Eystein and I are hoping that you've figured out the best 
experimental framework - e.g., what other forcing series to use. It 
would be great if you used the same volcanic and trace gas series, if 
that is possible. I'm cc'ing this to Keith in the hope that he can 
help us make sure we're making the right decisions.

Also, since Keith is going to be making the new figure comparing the 
range of obs climate over the last 1000 years to the range of 
simulated climate over the last 1000 years (i.e., like the fig we 
showed in our second/Thursday plenary talk), it would be worth 
thinking if there is any way to scale the solar forcing over the 
entire last 1000 years to Judith's new reduced-amplitude solar 
forcing. I'm not sure this is straightforward or not, but if it was 
possible, we'd have your new runs for inclusion in the new obs vs. 
simulated climate fig too - this would be helpful.

In any case, the purpose of this email is just to see where we stand, 
and help keep things moving.

Thanks, Peck
