New study devalues carbon dioxide again

The uncertainty of science: A new study now suggests that previous climate models significantly over-estimated the effect increased carbon dioxide has on the climate.

Lewis co-authored a report with science writer Marcel Crok earlier this year that found many climate models running hot and overestimating climate sensitivity by 40 to 50 percent. The paper also criticized the IPCC for trying to hide the climate’s weaker response to carbon dioxide in its 2013 report by not giving a central climate sensitivity estimate.

Judith Curry, one of the co-authors, was also very quick to note that this result is by far not the final word. “There remains considerable meta uncertainty in the determination of climate sensitivity, including how the problem is even framed.”

Of course, if you are a global warming activist and communist, none of these minor details matter. Revolution for the climate is a must!
