Updated climate sensitivity estimates using aerosol-adjusted forcings and various ocean heat uptake estimates

Guest essay by Nic Lewis The Otto et al. paper has received a great deal of attention in recent days. While the paper’s estimate of transient climate response was low, the equilibrium/effective climate sensitivity figure was actually slightly higher than that in some other recent studies based on instrumental observations. Here, Nic Lewis notes that…

The academic response to the hypothesis has been, predictably, harsh and unforgiving with accusations flying…
