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 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 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?”
