I noticed there’s a post at Curry’s in which Frank Bosse uses my method (and my program) to adjust global temperature data for things we know cause it to fluctuate. By removing fluctuations of known origin (or at least, our best estimate of them), we hope to sharpen our view of the changes that are happening for other reasons.
As a starting point, Bosse takes the global temperature estimate of Cowtan & Way. The known factors allowed for are ENSO (the El Niño Southern Oscillation), atmospheric aerosols from volcanic eruptions, and variation in the output of the sun.
