ECS from a modified energy balance approach

Posted on February 4, 2018 by

Andrew Dessler’s paper (technically Dessler and Forster), which he mentioned in this comment, has now appeared as a pre-print. Essentially, they use an energy balance approach to estimate equilibrium climate sensitivity (ECS), but – as I mentioned in this post … Continue reading →

Narrowing the climate sensitivity range?

Posted on January 20, 2018 by

There have been a couple of recent papers presenting analyses that claim to have narrowed the likely range for equilibrium climate sensitivity (ECS). One is Dessler et al. (currently a discussion paper under review) which suggests that the 500hPa tropical … Continue reading →

More about Equilibrium Climate Sensitivity

Posted on December 14, 2017 by

It’s currently the AGU Fall Meeting and there was a session on Climate sensitivity and feedbacks. It included talks by Kate Marvel and Kyle Armour, and I noticed that the Convener, Andrew Dessler, had tweeted This leads to one of … Continue reading →

A bit more about clouds

Posted on October 7, 2017 by

A few years ago I posted a video by Andrew Dessler that was discussing whether or not Equilibrium Climate Sensitivity could be less than 3oC. The bottom line was that the best estimate for ECS is about 3oC. Given that … Continue reading →

The enhanced greenhouse effect

Posted on May 28, 2017 by

This is really just an opportunity to write a little bit about science, and to advertise other people’s work. There are some who suggest that adding CO2 to the atmosphere can’t lead to warming because CO2 absorption is saturated. This … Continue reading →

ECS ~1K?????

Posted on May 13, 2016 by

There is a new paper that is being somewhat uncritically accepted at the new Climate “Skepticism” site (and, yes, the inverted commas are necessary) and at Bishop Hill. It’s by someone called J. Ray Bates and claims to estimate climate … Continue reading →

Water vapour and climate

Posted on January 23, 2016 by

Peter Sinclair has video interview with Andrew Dessler about water vapour and climate. The video doesn’t really say anything all that surprising. We are now reasonably sure that relative humidity remains roughly constant as we warm. This then allows us … Continue reading →
