Meta-uncertainty in the determination of climate sensitivity

by Judith Curry Two heavyweight climate scientists have published very different ideas about how much the Earth is going to warm in the coming decades. – Washington Weather Gang

The Forest 2006 climate sensitivity study and misprocessing of data – an update

by Nicholas Lewis Some of you may recall my guest post at Climate Etc last June, here, questioning whether the results of the Forest et al., 2006, (F06) study on estimating climate sensitivity might have arisen from misprocessing of data.

UK MSM on climate sensitivity

by Judith Curry If climate scientists were credit-rating agencies, climate sensitivity would be on negative watch. But it would not yet be downgraded. – The Economist

New perspectives on climate sensitivity

by Judith Curry Here is a summary of some important new papers on the topics of climate sensitivity and attribution.

Climate sensitivity in the AR5 SOD

by Judith Curry By far the most important debate about climate change is taking place among scientists, on the issue of climate sensitivity: How much warming will a doubling of atmospheric carbon dioxide actually produce?  – Matt Ridley

What climate sensitivity says about the IPCC assessment process

by Rud Istvan If climate sensitivity is high, then modest GHG increases cause significant warming. If it is low, then significant GHG increases will not. Analysis of the IPCC assessment of sensitivity provides another window into the ‘government-climate research’ complex … Continue reading

Climate sensitivity discussion thread

by Judith Curry There are several recent estimates of climate sensitivity that are worth taking a look at.

A biologist’s perspective on ice ages and climate sensitivity: Part I

by DocMartyn This is the first of a three part presentation where I will attempt to explain the climate of the last 800,000 thousand years, drawing on the role of the biosphere’s response to interstellar dust.

by WebHubTelescope . Schmittner et al have written a paper titled “Climate Sensitivity Estimated from Temperature Reconstructions of the Last Glacial Maximum” (Science Nov 24. 2011).

Probabilistic estimates of transient climate sensitivity

by Judith Curry An important new paper on this topic has been published in J. Climate, that raises the bar in terms of uncertainty analysis.

Climate sensitivity to ocean heat transport

by Judith Curry A paper in press in the Journal of Climate  provides some insight into the interaction of cloud feedback with ocean heat transport.

Climate sensitivity follow-up

by Nicholas Lewis JC note:  Pursuant to Nic’s post on “The IPCC’s alteration of Forster & Gregory’s model-independent climate sensitivity results,” he has sent a letter to Gabi Hegerl, who was coordinating lead author on chapter 9 of the IPCC … Continue reading

The IPCC’s alteration of Forster & Gregory’s model-independent climate sensitivity results

by Nicholas Lewis The IPCC Fourth Assessment Report of 2007 (AR4) contained various errors, including the well publicised overestimate of the speed at which Himalayan glaciers would melt. However, the IPCC’s defenders point out that such errors were inadvertent and … Continue reading
