Just two explanatory variables (GHG and AMO) still account for 93% of the temperature variance. Dr. Leif Svalgaard sends word of this article in Geophysical Research letters by Petr Chylek, James D. Klett, Glen Lesins, Manvendra K. Dubey and Nicolas Hengartner Article first published online: 5 MAR 2014 DOI: 10.1002/2014GL059274 Abstract A multiple linear regression analysis…
The solar data from the NOAA Space Weather prediction center has been posted, and like the global temperature, there isn’t much change. Sunspot numbers are down slightly, but still up from most of 2012/2013. The double peak looks more prominent. Solar radio flux shows a similar double peak pattern.

From the International Institute for Applied Systems Analysis The tiniest greenhouse gas emitters Climate feedbacks from decomposition by soil microbes are one of the biggest uncertainties facing climate modelers. A new study from the International Institute for Applied Systems Analysis (IIASA) and the University of Vienna shows that these feedbacks may be less dire than…
One wonders how they can make claims like that when we see models vs reality like this: Future generations will have to pay more for today’s carbon emissions than what governments across the world currently understand. The climate models used by policymakers around the world to estimate the economic and social costs of CO2 emissions…
Guest essay by Eric Worrall Stephan Lewandowsky (of retracted Recursive Fury fame ) has just released a paper supporting the “precautionary principle” (h/t JoNova). According to Lewandowsky, the more uncertain you are about risk, the more you should spend to contain the risk. Lewandowsky of course applies this principle to climate sensitivity – he suggests…
(See the note below before taking this post seriously – Anthony) Guest essay by Steven Wilde Here we see the classic energy budget analysis supporting the hypothesis that the surface of the Earth is warmer than the S-B equation would predict due to 324 Wm2 of ‘Back Radiation’ from the atmosphere to the surface. It…
The title of the post, of course, assumes that an El Niño event will form this year and carry over into the next. This post is intended for persons new to the topic of El Niño events—and for those who are familiar with them. It should help provide a number of different perspectives on the…
From Florida State University and the department of we’ve heard all this before comes this story Researchers: Permafrost thawing could accelerate global warming TALLAHASSEE, Fla. — A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which…
