What’s the worst case? Climate sensitivity

Posted on April 1, 2019 by curryja | Reposted from Climate Etc. by Judith Curry Are values of equilibrium climate sensitivity > 4.5 C plausible? For background, see these previous posts on climate sensitivity [link] Here are some possibilistic arguments related to climate sensitivity.  I don’t think the ECS example is the best one to…

Cliff Mass: victim of academic political bullying

Reposted from Judith Curry’s Climate Etc. by Judith Curry There is a disturbing story coming out of the University of Washington surrounding Cliff Mass. In preparing this article, I have received material from a member of the Department of Atmospheric Sciences at the University of Washington. I also ran into another member of the Department…

New CERES Data

Guest Post by Willis Eschenbach Every fall, there’s good news in the world of satellite information, because the CERES satellite folks add one more year’s worth of data to their full dataset. So I went and downloaded the whole 18 years worth, which is close to a full gigabyte of data … The other good…

Warming patterns are unlikely to explain low historical estimates of climate sensitivity

By Nic Lewis Plain language summary A new paper led by a UK Met Office scientist claims that accounting for the difference in the spatial pattern of surface temperature change between that in the historical period and that projected under long-term CO2-forcing substantially increases historical estimates of climate sensitivity. The claims are based on simulations…

Stacking Up Volcanoes

  Guest Post by Willis Eschenbach [See Update at end] As readers of my posts know, I’ve held for many years that there are a variety of emergent phenomena that regulate the earth’s temperature. See my posts The Thermostat Hypothesis and Emergent Climate Phenomena for an overview of my hypothesis. One of the predictions derivable…

Symmetry and Balance

Guest Post by Willis Eschenbach The CERES satellite dataset is a never-ending source of amazement and interest. I got to thinking about how much energy is actually stoking the immense climate engine. Of course, virtually all the energy comes from the sun. (There is a bit of geothermal, but it’s much less than a watt…
