Sea surface warming and cloud feedbacks

I wrote a post a while agoe about a paper that was suggesting that the reason for the difference between the observationally-based estimates for climate sensitivity, and other estimates, was that the pattern of sea surface temperatures can produce different … Continue reading

Ocean CO2 uptake – part 2

This is really a continuation of my post in which I tried to lay out the basic chemical reactions associated with the uptake of by the ocean. Nick Stokes has a similar post and has a nice online calculator. What … Continue reading

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
