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
