Not All That Sensitive

Guest Post by Willis Eschenbach
For no particular reason, I got to thinking about the non-global nature of the incoming energy. And this led me to consider the sensitivity of the surface to changes in the radiation absorbed by the surface.
The sensitivity of the surface to changes in absorbed radiation is a central, critical question in climate science. The claim is that the change in global average temperature is equal to the change in absorbed radiation times the “equilibrium climate sensitivity”, abbreviated as ECS. The ECS is assumed to be a constant.
However, despite hundreds of thousands of dollars, work-hours, and computer-hours dedicated to determining the value of the ECS, the uncertainty about its value has only continued to increase.
