More low climate sensitivity

This paper A lower and more constrained estimate of climate sensitivity using updated observations and detailed radiative forcing time series from Skeie et al is now in open peer review at Earth System Dynamics. They say an ECS of 1.84 See Figure E2 from the paper.

The early chill in the Arctic continues

Temperature above 80 degrees north drops below freezing early, and continues to drop. Many people have been watching the remarkable early drop in air temperature at the DMI plot here: This drop looks to be about two weeks early. As this next analysis of sea surface temperature shows, much of the area is below freezing.…
