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

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
