Is The Climate Sensitivity Less Than 2°C?

Andrew Dessler, Professor of Atmospheric Sciences at Texas A&M University, uploaded a good short video where he talks about how likely it would be that climate sensitivity is less than 2 degrees. It puts some of the more recent papers into context as to why they might be underestimating climate sensitivity:

My only nitpick about this video is that he didn’t mention that if you look at how our planet has reacted in the distant past a low climate sensitivity isn’t supported. If you do a review of these studies it shows that the climate sensitivity of our planet is somewhere between 2 and 4.5 degrees (with a few big jumps upwards, but those are the exception).
