A New Index to Willis’s Posts

Guest Post by Willis Eschenbach Well, my old index to my posts was out of date, and I finally got tired of not being able to find things that I’ve written. This is me trying to figure it out. So I wrote a program in the computer language “R”. It takes as input a list…

CERES Edition 4 and the Cloud Radiative Effect

Guest Post by Willis Eschenbach One of the enduring questions in climate involves what is usually called “cloud feedback”. When the earth warms up a bit, the clouds change in response. The question is the direction of that response. Does the change in clouds amplify a warming, or does it reduce a warming? Here’s Dr.…

Been There, Exceeded That

Guest Post by Willis Eschenbach Much angst has been expended on a very vague climate threshold, the so-called “2 degrees Celsius limit”, sometimes called the “2° global warming tipping point”.  I find it all quite hilarious, for a reason that will become clear shortly. First a bit of prologue. Here’s the New Republic from 2014…

Guest Post by Willis Eschenbach I got to thinking about the records of the sea level height taken at tidal stations all over the planet. The main problem with these tide stations is that they measure the height of the sea surface versus the height of some object attached to the land … but the…

More On Svensmark and Cosmic Rays

Last week, Anthony highlighted a study by Svensmark, Shaviv et al. in a post entitled New paper: The missing link between cosmic rays, clouds, and climate change on Earth. While some were enthusiastic about their claims, Leif Svalgaard and I were much more restrained in our opinions. As a result, I was interested in an analysis…

Delta T and Delta F

Guest Post by Willis Eschenbach The fundamental and to me incorrect assumption at the core of the modern view of climate is that changes in temperature are a linear function of changes in forcing. Forcing is defined as the net downwelling radiation at the top of the atmosphere (TOA). According to this theory, in order…
