Earth System Sensitivity and things

There was a recent paper about the Evolution of global temperature over the past two million years. The reason it is controversial is not because it produces a global temperature reconstruction for the last 2 million years, but because it … Continue reading

The attribution question

It seems as though the issue of trying to attribute an anthropogenic influence to an extreme weather event is controversial on a number of levels. It sometimes seems to divide even those who largely agree, and almost always produces a … Continue reading

Emission reductions, negative emissions, and overshoots

I was wanting to briefly discuss a paper I ran across that looks at What would it take to achieve the Paris temperature targets? The basic idea is to develop emission pathways that depend on three basic parameters; the time … Continue reading

Model tuning

Came across a very interesting paper on the art and science of climate model tuning. Based on the comments here, it appears that some are interpreting this as confirming their claims that climate models are tuned to give preferred results. … Continue reading

Full-depth OHC

Since my holiday is now over, I thought I might briefly comment on a recent paper by Cheng et al., called Observed and simulated full-depth ocean heat-content changes for 1970–2005. John Abraham, one of the authors, has already discussed it … 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
