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 Equilibrium additional warming would be 1 K, even under outdated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,
Linkname: Global Warming Commitment : Temperatures Would Rise Even
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.)
