Dessler e-mail to Lindzen on 1/14/11


Your question gets to the same issue that I am after: what is the
cause of the temperature variations over the last 10 years. If it
turns out that clouds are responsible, then that would indeed
challenge my feedback estimate.

However, I suggest that ENSO is responsible for the temperature
variations. I've repeatedly asked Roy for evidence that clouds are
responsible, and he cannot provide anything beyond some ambiguous
correlations. The problem with that of course is that correlations do
not tell us causality.

If you have evidence that the variations over the last decade are
caused by clouds, then please let me know what that evidence is.
