Re: GG Reality 2008, `carbonate pump'

Dear Dr. Sommerkorn,

I forgot to mention the last blunder
(I did not mark it conspicuously enough in the printed paper...).

It appears on page 13 in the third paragraph. 0.6 K additional warming concerns _2100_, under the old AR4 assumptions (those of Meehl et al as well). Equilibrium additional warming would be 1 K, even under outdated assumptions, as a 2001 NOAA page says,

          With No ...

Recent knowledge (longterm climate sensitivity being twice the Charney one) would change it rather to 2 K. 2+-1 K is perhaps a 90 % confidence interval for a realistic guess of a maximal further temperature increase within next centuries, for zero carbon net anthropogenic emissions further on. (I was unable to find a recent paper about it.)

best regards,
