Could we be wrong about global warming?

Via USA Today:

Could the best climate models -- the ones used to predict global warming -- all be wrong?

Maybe so, says a new study published online today in the journal Nature Geoscience. The report found that only about half of the warming that occurred during a natural climate change 55 million years ago can be explained by excess carbon dioxide in the atmosphere. What caused the remainder of the warming is a mystery.

"In a nutshell, theoretical models cannot explain what we observe in the geological record," says oceanographer Gerald Dickens, study co-author and professor of Earth Science at Rice University in Houston. "There appears to be something fundamentally wrong with the way temperature and carbon are linked in climate models."

Which is sorta what I've been clamoring about all along -- that there are SO many variables involved in climate science that to nail it all down to "excess" carbon in the atmosphere is, well, silly. This, contrary to the claims of those like perpetual DE blog commenter Perry and various bloggers. I've never said that global warming is not occurring like some have ... what I've maintained is that there is NO definitive word on man's influence on climate change, and as such we should be VERY wary of moronic legislation like "cap and trade."

Look, the average American doesn't want a sh**ty environment. Just compare how things were in the US today to some 30 years ago. It's much cleaner today. But we also don't want our federal government taxing the hell out of us to prevent something that is, in all likelihood, not that big a problem.
