Climate models "fundamentally wrong" on CO2

Don't forget that these models are the same ones on which governments around the world are basing their misguided policies on "climate change". And now it appears that there are serious problems with the way in which they model the effect of CO2. A study has found that climate models explain only about half of the heating that occurred during a well-documented period of rapid global warming in Earth's ancient past, known as the Palaeocene-Eocene Thermal Maximum or PETM:

“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.”

During the PETM, for reasons that are still unknown, the amount of carbon in Earth’s atmosphere rose rapidly. For this reason, the PETM, which has been identified in hundreds of sediment core samples worldwide, is probably the best ancient climate analogue for present-day Earth.

The conclusion, Dickens said, is that something other than carbon dioxide caused much of the heating during the PETM. “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.”

Hang on - how many of you have spotted the obvious problem with all this? Yes, that's right. The science is settled - debate's over. Move along. Nothing to see here...
