Beyond equilibrium climate sensitivity

Since I’ve written about climate sensitivity before, and since I have a few free moments, I thought I would briefly highlight a new paper by Knutti, Rugenstein, and Hegerl called Beyond Equilibrium Climate Sensitivity. It’s really a review of a … Continue reading

Reconciling climate sensitivity estimates – part III, or IV?

I mentioned in a recent post that there was a new paper that claims to reconciles climate sensitivity estimates. The basic issue is that observationally-based climate sensitivity estimates have a range of about 1.5oC to about 3oC, while climate model … Continue reading

A reduced climate sensitivity!

Now that I have your attention, I should probably make clear that this post is not about the Earth. I’m just back from a meeting where one of the speakers was Ian Boutle, lead author of a paper in which … Continue reading

Non-linear climate sensitivity

Rather strangely, the recent Science Advances paper Nonlinear climate sensitivity and its implications for future greenhouse warming, that’s been getting some attention recently, made it into our Journal Club today (and it had nothing to do with me). It’s, consequently, … Continue reading

Climate Sensitivity on the Rise

There’s a Nature news & views article by Kyle Armour called Projection and prediction: Climate sensitivity on the rise. It discusses various analyses that indicate that simple energy balance methods tend to under-estimate climate sensitivity. Normally, I would write a … Continue reading

Climate sensitivity reconciled?

There’s a really interesting paper by Mark Richardson, Kevin Cowtan, Ed Hawkins, and Martin Stolpe called Reconciled climate response estimates from climate models and the energy budget of Earth. Ed already has post that explains it all very clearly, so … Continue reading

Bayesian estimates of climate sensitivity

Thanks to Bill Shockley I’ve been made aware of new paper by James Annan about recent developments in Bayesian estimation of climate sensitivity. It covers many things I’ve been wondering about, so I found it very interesting. I don’t need … Continue reading

Feedbacks, climate sensitivity and the limits of linear models

Since I’ve discussed climate sensitivity here quite a lot, I thought I would highlight a recent paper, by Knutti & Rugenstein, called feedbacks, climate sensitivity and the limits of linear models. It’s a very nice, and readable, summary and – … Continue reading

Richard Tol’s climate sensitivity estimate

In his interview with Roger Harrabin, Richard Tol said something quite interesting. He claimed: RT: The very start of my career was about trying to show that CO2 and other greenhouse gases cause climate change. We were one of the … Continue reading

Some thoughts on climate sensitivity

Semyorka posted a comment on my previous post that highlighted a paper that I had’t seen before. The paper is Global atmospheric downward longwave radiation over land surface under all-sky conditions from 1973 to 2008 which tries to determine (as … Continue reading
