In a new paper (.pdf link) published in the journal Climate Dynamics, Judith Curry and Nic Lewis claim that climate sensitivity is on the low end of IPCC projections. This wouldn't be big news, execpt of course it's the kind of paper that the conservative media loves, and a peer-reviewed paper is exactly the sort of thing Curry needs to shore up her crumbling credibility.

Whether or not it stands up to academic scrutiny remains to be seen but Carbon Brief helpfully puts the important point in context: No, this doesn't mean emission cuts can happen more slowly. Regardless of how press spins the study, Oxford's Myles Allen told Carbon Brief that even a 25% reduction in sensitivity "would mean the changes we expect between now and 2050 might take until the early 2060s instead." This echoes a point made by Dr. Mann back in March, when he took on this same subject!

Relatedly, there is also a profile of Curry on ClimateWire, which mentions an interesting fact- in 2006, Curry and her husband launched a climate and weather forecasting company whose clientele is the fossil fuel industry.
