Skip to comments.New blockbuster paper finds man-made CO2 is not the driver of global warming

An important new paper published today in Global and Planetary Change finds that changes in CO2 follow rather than lead global air surface temperature and that "CO2 released from use of fossil fuels have little influence on the observed changes in the amount of atmospheric CO2" The paper finds the "overall global temperature change sequence of events appears to be from 1) the ocean surface to 2) the land surface to 3) the lower troposphere," in other words, the opposite of claims by global warming alarmists that CO2 in the atmosphere drives land and ocean temperatures. Instead, just as in the ice cores, CO2 levels are found to be a lagging effect of ocean warming, not significantly related to man-made emissions, and not the driver of warming.

The absorption of IR photons by CO2 molecules is well understood at the macro level. It's the same as with partly cloudy skies at night. As clouds go over reporting stations you can actually see the temperature stop dropping then continue when the clouds move off. Same as a greenhouse which stops convection but also absorbs and reemits heat. It's easy to test by tying a space blanket way up in a tree (so that there is no convection stopping effect) and sleeping under that versus sleeping under the stars.
At the quantum mechanical level it is considerably more complex. Photons may not be absorbed and reemitted the way we think they are.
OK, thanks for the correction. I would think the ice core data would be more significant and more definitive than any short term observations though.
This has been known all along.
Bump for later.
That's steep for online content...
These scientists must be new at this “study” stuff. They obviously didn’t realize that if they find out there really is no problem, they won’t be eligible for more federal study money for this doomsday “problem.”
I think the article has new information. It isn’t talking about temperature vs. CO2 eons ago. It’s talking about recent information. I think it is another nail in the coffin of CAGW.
Not that you’d know it from listening to the Republican candidate for president of the United States;
I am not a scientist myself, but my best assessment of the data is that the world is getting warmer, that human activity contributes to that warming, and that policymakers should therefore consider the risk of negative consequences.”
