Average TOA Radiation Imbalance 2000 2014

Temperature and TOA Forcing

Guest Post by Willis Eschenbach I’ve been thinking about temperature and top-of-atmosphere (TOA) forcing. TOA forcing is the imbalance between the TOA upwelling and downwelling radiation. The CERES satellite dataset contains observations of the TOA radiation imbalance on a gridcell-by-gridcell basis. It is calculated as the downwelling solar radiation for that month by gridcell, minus…

The Icebox Heats Up

Guest Post by Willis Eschenbach Well, either it’s a genetic defect or I’m just a glutton for punishment, but I’m going to delve some more into the ice ages. This is a followup to my previous post, Into and Out Of The Icebox. Let me start by looking at the cycles in the insolation and…

Into and Out of the Icebox

Guest Post by Willis Eschenbach Inspired by a random comment by Steve McIntyre over at his marvelous blog Climate Audit, I got to thinking about the ice ages. I’ve long heard that the ice ages are caused by the changes in summer insolation in the northern hemisphere. As the story goes, the Milankovitch cycles of…
