Arctic Layer Cake

Guest Post by Willis Eschenbach There’s a recent paper paywalled here, called Arctic winter warming amplified by the thermal inversion and consequent low infrared cooling to space. Fortunately, the Supplementary Online Information is available here, and it contains much valuable information. The paper claims that during the arctic winter, the atmospheric radiation doesn’t go out to…

New WUWT-TV segment: Slaying the 'slayers' with Watts

As readers may know, Dr. Roy Spencer and I have had a long running disagreement with the group known as “Principia Scientific International” aka the Sky Dragon Slayers after the title of their book. While I think these people mean well, they tend to ignore real world measurements in favor of self-deduced science. They claim…

The Spencer Challenge to Slayers/Principia

Dr. Roy Spencer has made a challenge to the Slayers/Principia folks who keep insisting the greenhouse effect doesn’t exist at all. For example, see the front page claim at right from the Principia web page where they claim the greenhouse effect is “bogus”. My view has always been that it exists. and has been effectively…

The R. W. Wood Experiment

Guest Post by Willis Eschenbach Pushed by a commenter on another thread, I thought I’d discuss the R. W. Wood experiment, done in 1909. Many people hold that this experiment shows that CO2 absorption and/or back-radiation doesn’t exist, or at least that the poorly named “greenhouse effect” is trivially small. I say it doesn’t show…

Myths and Facts about Global Warming

From Friends of Science. Be sure to visit their page and bookmark it. COMMON MISCONCEPTIONS ABOUT GLOBAL WARMING MYTH 1:  Global temperatures are rising at a rapid, unprecedented rate. FACT:  The HadCRUT3 surface temperature index shows warming to 1878, cooling to 1911, warming to 1941, cooling to 1964, warming to 1998 and cooling through 2011.…

Earth's entire thermal infrared spectrum observed

From AGU highlights, interesting, but readers should note that this is one point on Earth in Chile, not a summation of the  atmospheric absorption, emission, and transmission of infrared radiation for the entire globe. For first time, entire thermal infrared spectrum observed The driving mechanism of the greenhouse effect, and the underpinning of modern anthropogenic…

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 particular, feedback values of ~2.0 W/m2K-1 favored by current GCM models lead to non physical results at solar radiation levels present one billion years ago.…
