On an error in applying feedback theory to climate

January 30, 2018

An empirical comparison of published official estimates of industrial-era net anthropogenic forcings with observed warming indicates climate models grossly overestimate the effect various feedback mechanisms have on temperatures.

Most of the warming postulated by climate models comes from assumptions concerning a variety of feedback mechanisms which modelers believe will amplify the warming effect of increasing concentrations of greenhouse gasses in the atmosphere. Observational data indicates climate models grossly overestimate the warming that should be expected from the feedback mechanisms. This overestimate explains why climate models dramatically overstate the amount of warming the earth has experienced since the beginning of the industrial revolution.
