Australian scientists take 6 degrees of global warming off the table, say it is closer to 2 degrees
From the University of Melbourne Scientists narrow global warming range Australian scientists have narrowed the predicted range of global warming through groundbreaking new research. Scientists from the University of Melbourne and Victoria…
Updated climate sensitivity estimates using aerosol-adjusted forcings and various ocean heat uptake estimates
Guest essay by Nic Lewis The Otto et al. paper has received a great deal of attention in recent days. While the paper’s estimate of transient climate response was low,…
Model Climate Sensitivity Calculated Directly From Model Results
Guest Post by Willis Eschenbach [UPDATE: Steven Mosher pointed out that I have calculated the transient climate response (TCR) rather than the equilibrium climate sensitivity (ECS). For the last half…
Why the new Otto et al climate sensitivity paper is important – it's a sea change for some IPCC authors
Yesterday, WUWT was honored to have a guest essay by co-author Nic Lewis on the new Otto et al paper that pegs Transient Climate Response (TCR) at 1.3°C along with Equilibrium…
New paper shows transient climate response less than 2°C

New paper from Otto et al and Nic lewis shows transient climate sensitivity less than 2C
UPDATE: this post has been superseded by the new guest essay from Nic Lewis which you can see here: New paper shows transient climate response less than 2°C
Claim: How the IPCC arrived at climate sensitivity of about 3 deg C instead of 1.2 deg C.
UPDATE from Girma: “My title should have been ‘How to arrive at IPCC’s climate sensitivity estimate’ instead of the original” Guest essay by Girma Orssengo, PhD 1) IPCC’s 0.2 deg…
The beginning of the end: warmists in retreat on sea level rise, climate sensitivity
The forecast: It seems there’s less chance of gloom and doom these days. For sea level rise, now a maximum of about two feet by 2100. As for climate sensitivity,…
A compilation of lower climate sensitivities, plus a new one
Still Another Low Climate Sensitivity Estimate Guest post By Patrick J. Michaels and Paul C. “Chip” Knappenberger Global Science Report is a weekly feature from the Center for the Study…
Some sense about sensitivity
Excerpts from The Register, coverage of the Nic Lewis paper. This graph below from Bishop Hill shows that it isn’t just one paper, but several now that show lower climate…
Dana Nuccitelli's meany mode is like stinky cheese
Dana (Scooter) Nuccitelli, lead attack kid at the SkS Treehut gets schooled. Bishop Hill writes: Last week I ribbed Dana Nuccitelli and Gavin Schmidt over the former’s comparing the mean…
Efficacy Of Green House Gas Forcing Compared To Solar Forcing
Guest post by Bob Irvine SUMMARY This paper outlines an idea or hypothesis that should be discussed. This idea has the huge advantage of being supported by all the available…
Numeracy in Climate Discussions – how long will it take to get a 6C rise in temperature?
The answer may surprise you Note: This essay is a result of an email discussion this morning, I asked Dr. Happer to condense and complete that discussion for the benefit…
Another paper finds lower climate sensitivity
Yesterday we talked about the new paper from Nic Lewis, now Troy Masters has a new paper in press at Climate Dynamics here. Observational estimate of climate sensitivity from changes…
An objective Bayesian estimate of climate sensitivity
Guest post by Nic Lewis Many readers will know that I have analysed the Forest et al., 2006, (F06) study in some depth. I’m pleased to report that my paper…
A Comparison Of The Earth's Climate Sensitivity To Changes In The Nature Of The Initial Forcing
Guest post by Bob Irvine ABSTRACT The Earth’s feedback response to warming is independent of the nature of the forcing that caused that warming. The question I intend to examine…
A sea-change on climate sensitivity at The Economist
People send me stuff, today it was this “editors picks” from John Micklethwait, editor of The Economist. After years of being pro-warming, I was shocked to see this headline as…
The Revkin-Gavin debate on lower climate sensitivity
Lower climate sensitivity is getting some mainstream discussion. Last week at WUWT, we had this story: BREAKING: an encouraging admission of lower climate sensitivity by a ‘hockey team’ scientist, along…
