Guest Post by Willis Eschenbach. TL;DR: Ramanathan proposed that the "greenhouse effect" could be measured as surface upwelling longwave minus top-of-atmosphere (TOA) upwelling longwave. However, this ignores the contributions to TOA upwelling longwave from 1) atmospheric absorption of solar energy, and 2) surface-to-atmosphere net energy transfer of latent heat of evaporation/condensation and sensible heat. In
Pro: the Greenland Ice Melting Will Cause Disastrous Sea Level Rise. From early 2003 to mid-2013, the total mass of ice in Greenland declined at a progressively increasing rate. In mid-2013, an abrupt reversal occurred, and very little net ice loss occurred in the next 12–18 months. Gravity Recovery and Climate Experiment (GRACE) and global
Guest Post by Willis Eschenbach. The CERES dataset continues to yield new insights. My joy is to graph different relationships and then see what I can learn and find out from the graph. Inter a lot of alia, the CERES dataset allows us to calculate the amount of the very poorly named "greenhouse radiation". This
