Avoiding the Net Zero Trap

By Andy May Clintel has just put out a new publication, We Can Still Avoid the Net Zero Trap, by Kees de Lange and Guus Berkhout.

Climate Model Bias 7: WGIII

By Andy May Christian Freuer has translated this post into German here. This is the last post of a seven part series on the bias in the IPCC AR6 report, links to the other parts: 2. Modeling Greenhouse Gases 3. Solar Input 4. Convection and atmospheric circulation 5. Storminess 6. IPCC AR6 WGII In theContinue reading “Climate Model Bias 7: WGIII”

Climate Model Bias 6: WGII

The IPCC AR6 WGII report examines the impact of climate change, but ignores the benefits of warming and additional CO2.

Climate Model Bias 5: Storminess

Does storminess (extreme weather) go up as global temperature increases like the IPCC says? Or does it go down as the data says? Plus, a summary of my criticism of the AR6 WGI report.

Climate Model Bias 4: Convection and atmospheric circulation

By Andy May This is part 4 of a seven part series, the other parts are listed below: 1. What is a climate model? 2. Modeling Greenhouse Gases 3. Solar Input 5. Storminess 6. IPCC AR6 WGII 7. IPCC AR6 WGIII In part 3 we discussed the relationship between changes in solar activity and climate changes. Exactly how solar changes affectContinue reading “Climate Model Bias 4: Convection and atmospheric circulation”

Climate Model Bias 3: Solar Input

Climate Model Bias 1: What is a Model?

By Andy May Christian Freuer has translated this post into German here. This is the first post of a seven-part series on bias in the IPCC AR6 report, here are links to the other six parts: 2. Modeling Greenhouse Gases 3. Solar Input 4. Convection and atmospheric circulation 5. Storminess 6. IPCC AR6 WGII 7.Continue reading “Climate Model Bias 1: What is a Model?”

Climate, CO2, and the Sun

By Andy May Christian Freuer has translated this post into German here. In my previous post on multiple regression of known solar cycles versus HadCRUT5, I simply threw the solar cycles, ENSO, and sunspots into the regression blender and compared the result to various models that included CO2. Before reading this post, it is aContinue reading “Climate, CO2, and the Sun”

Modeling HadCRUT5 with CO2 and without CO2

By Andy May I hate statistics, as many of you know. Some people think statistics and/or statistical models that meet standard statistical criteria are facts. The IPCC can be like that. They statistically model global surface temperatures with models of volcanic and anthropogenic forcing and compare the model to one with only volcanic forcing. ThenContinue reading “Modeling HadCRUT5 with CO2 and without CO2”
