So I would be interested in ways that the increasing cloud cover hypothesis put forward in the Nature article could be verified. If you're interested, I already found an article indicating that high-resolution estimates of cloud cover for a particular region differ significantly from low-resolution ISCCP data.
What about the huge disparity between the statistical difference of roughly 12% worst-case increase in extinctions determined by the refuting author vs the 60-ish% claimed by the author(s) of the Nature article? That is a glaring, significant difference.
Cogitator,
Don't waste any more cogitation time on weather models and global warming. The METS model is one of the biggies, and it predicts that summer rainfall in the Central Sahara is the same as Ireland.
For those unfamiliar with the global warming bit, the Central Sahara last recorded a summer rain nearly a century ago.
Check Google for Dr. Patrick Michaels, Professor Linzden at MIT, etc..
