That's my only quibble with this: Global Warming: Scientists' Best Predictions May Be Wrong:

"In a nutshell, theoretical models cannot explain what we observe in the geological record," said oceanographer Gerald Dickens, a co-author of the study and professor of Earth science at Rice University. "There appears to be something fundamentally wrong with the way temperature and carbon are linked in climate models." . . . The conclusion, Dickens said, is that something other than carbon dioxide caused much of the heating during the PETM (the Palaeocene-Eocene Thermal Maximum--an unusually warm period, much warmer than present day, about 55 million years ago). "Some feedback loop or other processes that aren't accounted for in these models -- the same ones used by the IPCC for current best estimates of 21st Century warming -- caused a substantial portion of the warming that occurred during the PETM."

The models are broken. They can't explain known conditions in the past. This makes their predictive "skill" regarding future climatic conditions utterly nonexistent.

Why then are we betting the entire world economy on bad computer models?
