Climate Model Bias 7: WGIII

By Andy May Christian Freuer has translated this post into German here. In the previous report, part 6 of this series, I discussed the bias in AR6 WGII. The major bias in the report stemmed from ignoring the benefits of a warmer world with more CO2 and only considering the possible problems. They also assumed,Continue reading “Climate Model Bias 7: WGIII”

Climate Model Bias 3: Solar Input

By Andy May Christian Freuer has translated this post into German here. In part 2 we discussed the IPCC hypothesis of climate change that assumes humans and our greenhouse gas emissions and land use choices are the climate change “control knob.”[1] This hypothesis underpins their attempts to model Earth’s climate. But the model output failsContinue reading “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. There are three types of scientific models, as shown in figure 1. In this series of seven posts on climate model bias we are only concerned with two of them. The first are mathematical models that utilize well established physical, and chemical processesContinue reading “Climate Model Bias 1: What is a Model?”

Climate Model Bias 2: Modeling Greenhouse Gases

By Andy May Christian Freuer has translated this post into German here. Since the late 19th century, with the work by Svante Arrhenius, climate models have been used to estimate the amount of global warming due to human greenhouse gas emissions.[1] Due to the complexity of Earth’s weather and climate, the connection between climate change/globalContinue reading “Climate Model Bias 2: Modeling Greenhouse Gases”

Climate Model Bias 4: Convection and atmospheric circulation

By Andy May In part 3 we discussed the relationship between changes in solar activity and climate changes. Exactly how solar changes affect climate is not understood. It isn’t the immediate change in radiation delivered to the Earth, since that is too small to have much of an effect. So, it must be how Earth’sContinue reading “Climate Model Bias 4: Convection and atmospheric circulation”

A Conversation with Google Bard on the Consensus

By Andy May It turns out it is trivially easy to get Google’s AI product “Bard” to admit it is biased about climate change. Others, like Jonathan Cohler have managed to get “Bard” to admit it lied. I didn’t get that far, but I did get it to admit to bias. The last portion ofContinue reading “A Conversation with Google Bard on the Consensus”

Is AR6 the worst and most biased IPCC Report?

By Andy May This is the text of my presentation on Tom Nelson’s podcast which can be viewed here. The question and answers start at about 18:15 into the interview. Christian Freuer has translated this post to German here. The first IPCC Physical Science Basis report is called “FAR” and was first published in 1990.Continue reading “Is AR6 the worst and most biased IPCC Report?”
