Andrew Dessler rebuts Roy Spencer
Most of the focus at the moment is rightly on the coronavirus. Since I have no relevant expertise whatsoever, all I’ll say is that I hope everyone is doing their best to stay safe, and listening to the advice that’s … Continue reading
Estimates of the economic impact of climate change
I realise Stoat has already covered this, but I thought I would also briefly discuss it here. I posted a couple of tweets, that got quite a lot of responses, about the economic impacts of climate change, that tried to … Continue reading
The ECS is probably above 2K
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
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
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?
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
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
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
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?????
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
