Contrary to popular perception, the U.S. Midwest has seen little long-term summer warming. For precipitation, the slight drying predicted by climate models in response to human greenhouse gas emissions has not occurred; if anything, precipitation has increased.
Reposted from Dr. Roy Spencer’s blog February 6th, 2020 by Roy W. Spencer, Ph. D. Well, as I suspected (and warned everyone) in my blog post yesterday, a portion of my calculations were in error regarding how much CO2 is taken out of the atmosphere in the global carbon cycle models used for the RCP…
Reposted from Dr. Roy Spencer’s Blog February 5th, 2020 by Roy W. Spencer, Ph. D. Note: What I present below is scarcely believable to me. I have looked for an error in my analysis, but cannot find one. Nevertheless, extraordinary claims require extraordinary evidence, so let the following be an introduction to a potential issue…
By Rud Istvan, edited by Charles Rotter WUWT reader Max alerted us to a 1994 Naomi Oreskes et. al. paper published in the prestigious journal Science. Her paper was a critical analysis of Earth Science numerical models. I asked Rud to take a look, since he had previously written on climate models both here and…

It is also related to the forcing-feedback paradigm of climate change, which I usually defend — but which I…
12 October 2019 Pat Frank A bit over a month ago, I posted an essay on WUWT here about my paper assessing the reliability of GCM global air temperature projections in light of error propagation and uncertainty analysis, freely available here. Four days later, Roy Spencer posted a critique of my analysis at WUWT, here…
According to the climate models, snow cover should have steadily decreased for all four seasons. However, the observations show that only spring and summer demonstrates a long-term decrease. Ronan Connolly, Michael Connolly, Willie Soon, David R. Legates, Rodolfo Gustavo Cionco , and V. M. Velasco Herrera Abstract: Observed changes in Northern Hemisphere snow cover from…
By Christopher Monckton of Brenchley The prolonged el Niño of 2016-2017, not followed by a la Niña, has put paid to the great Pause of 18 years 9 months in global warming that gave us all such entertainment while it lasted. However, as this annual review of global temperature change will show, the credibility gap…
