“…may be Breaking Against Us.”
April 10, 2016
New study out this week looked at the physics of how clouds are represented in climate models, and concluded that the climate may be more sensitive to warming than previously thought.
Important to know that every year studies come out with implications for a higher, as well as possibly a lower, climate sensitivity. Over the last century, science has kept returning very closely to the “canonical” 3 ° C plus or minus 1.5°.
This study is important, but does not by itself reset the bar. More information needed, but as Mike Mann points out, uncertainty is not a reason to put off mitigation. The uncertainties, he says, “..may be breaking against us.”
