The ECS is probably above 2K

Posted on September 1, 2018 by

I have quite a large conference starting tomorrow, so will probably be too busy to write. To keep things ticking over I thought I would post this seminar given by Andrew Dessler, discussing his recent work on constraining the Equilibrium … Continue reading →

Lewis and Curry, again

Posted on April 27, 2018 by

I should probably say something about the new Lewis & Curry paper. It’s mostly an update to their earlier paper that I’ve discussed before. Bottom line; there are reasons to be cautious. The basic formalism is that one can use … Continue reading →

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 →
