Contemporary climatic analogs for 540 North American urban areas in the late 21st century

I guess sometimes you just have to throw the officially acknowledged lack of regional skill for GCM’s out the window~ctm From Nature Communications Abstract A major challenge in articulating human dimensions of climate change lies in translating global climate forecasts into impact assessments that are intuitive to the public. Climate-analog mapping involves matching the expected…

Global Mean Surface Temperature: Early 20th Century Warming Period – Models versus Models & Models versus Data

A Guest Post By Bob Tisdale This is a long post: 3500+ words and 22 illustrations. Regardless, heretics of the church of human-induced global warming who frequent this blog should enjoy it. Additionally, I’ve uncovered something about the climate models stored in the CMIP5 archive that I hadn’t heard mentioned or seen presented before. It…

Reassessing the RCPs

From Judith Curry’s Climate Etc Posted on January 28, 2019 by curryja | by Kevin Murphy A response to: “Is RCP8.5 an impossible scenario?”. This post demonstrates that RCP8.5 is so highly improbable that it should be dismissed from consideration, and thereby draws into question the validity of RCP8.5-based assertions such as those made in…

Mathematical modeling illusions

The global climate scare – and policies resulting from it – are based on models that do not work Dr. Jay Lehr and Tom Harris For the past three decades, human-caused global warming alarmists have tried to frighten the public with stories of doom and gloom. They tell us the end of the world as…

Greenland Near-Surface Land Air Temperature Data from Berkeley Earth Present Some Surprises

I enjoy surprises in data, especially when they might make alarmists unhappy. Willis Eschenbach’s post Greenland Is Way Cool at WattsUpWithThat prompted me to take a look at the Berkeley Earth edition of the Greenland TAVG temperature data. See Figure 1, which presents the graph of the annual Berkeley Earth TAVG temperature (not anomaly) data…

A Sea-Surface Temperature Picture Worth a Few Hundred Words!

We covered this paper when it was first released, here is some commentary on it – Anthony Guest essay by By PATRICK J. MICHAELS On January 7 a paper by Veronika Eyring and 28 coauthors, titled “Taking Climate Model Evaluation to the Next Level” appeared in Nature Climate Change, Nature’s  journal devoted exclusively to this one obviously under-researched subject. For years,…
