Observations on TOA Forcing vs Temperature
I recently wrote three posts (first, second, and third), regarding climate sensitivity. I wanted to compare my results to another dataset. Continued digging has led me to the CERES monthly…
Claim: Today's climate is more sensitive than that of the past
Press Release 12-107 Today’s Climate More Sensitive to Carbon Dioxide Than in Past 12 Million Years Geologic record shows evolution in Earth’s climate system The phytoplankton Emiliania huxleyi offers clues…
Sun and Clouds are Sufficient
Guest Post by Willis Eschenbach In my previous post, A Longer Look at Climate Sensitivity, I showed that the match between lagged net sunshine (the solar energy remaining after albedo…
A Longer Look at Climate Sensitivity
Guest Post by Willis Eschenbach After I published my previous post, “An Observational Estimate of Climate Sensitivity“, a number of people objected that I was just looking at the average…
An Observational Estimate of Climate Sensitivity
Guest Post by Willis Eschenbach “Climate sensitivity” is the name for the measure of how much the earth’s surface is supposed to warm for a given change in what is…
Clive Best gives evidence for negative water feedback in Earth's climate system using the faint sun paradox and CRUTEM4 data
Excerpts from Evidence for Negative Water Feedback by Clive Best Abstract: Positive linear climate feedback for combined water effects is shown to be incompatible with the Faint Sun Paradox. In…
What – you mean we aren't controlling the climate?
Correlation of Net CO2 emissions with climate properties shows that the growth in CO2 may be natural Story submitted by WUWT reader Steve Brown The narrative of the catastrophic anthropogenic…
Spencer’s posited 1-2% cloud cover variation found
In a nutshell, with a −1.6%per decade change in cloud cover during 1954–2005, it becomes a climate forcing. While China is not the world, it bears consideration. The Hockey Schtick…
Lower Climate Sensitivity Estimates: New Good News
Guest post by Chip Knappenberger, republished with permission from Master Resource (now on WUWT’s blogroll) “A collection of research results have been published in the peer-reviewed scientific literature in recent…
Volcanic Disruptions
Guest Post by Willis Eschenbach The claim is often made that volcanoes support the theory that forcing rules temperature. The aerosols from the eruptions are injected into the stratosphere. This…
Under the radar – the NAS Report
Guest Post by Willis Eschenbach Under the radar, and un-noticed by many climate scientists, there was a recent study by the National Academy of Sciences (NAS), commissioned by the US…
Declining global average cloud height: “A significant measure of negative feedback to global warming”
Guest post by Dr. Pat Michaels – reposted (with permission) from World Climate Report A new paper just published in Geophysical Research Letters by Roger Davies and Mathew Molloy of…
Support for the saturated greenhouse effect leaves the likelihood of AGW tipping points in the cold
From The Hockey Shtick, word of a new paper that supports Miskolczi’s theory of saturated greenhouse effect. We’ve seen this before, in the form of this graph. In 2006, Willis…
Jim Hansen's balance problem of 0.58 watts
From NASA Goddard, Jim Hansen reports on his balance problem: Earth’s Energy Budget Remained Out of Balance Despite Unusually Low Solar Activity A new NASA study underscores the fact that…
Sense and Sensitivity II – the sequel
By Christopher Monckton of Brenchley Joel Shore, who has been questioning my climate-sensitivity calculations, just as a good skeptic should, has kindly provided at my request a reference to a…
No new strange attractors: strong evidence against both positive feedback and catastrophe
This is a comment by Dr. Robert Brown on the What we don’t know about Earth’s energy flow post. I thought it was so insightful on the topic of climate stability…
Feedback about feedbacks and suchlike fooleries
By Christopher Monckton of Brenchley Responses to my post of December 28 about climate sensitivity have been particularly interesting. This further posting answers some of the feedback. My earlier posting…
Unified Climate Theory May Confuse Cause and Effect
Guest Post by Ira Glickstein The Unified Theory of Climate post is exciting and could shake the world of Climate Science to its roots. I would love it if the…
Unified Theory of Climate
Note: This was a poster, and adopted into a blog post by the author, Ned Nikolov, specifically for WUWT. My thanks to him for the extra effort in converting the…
