Evidence Over Ideology
Computer Models versus Observations
The fears of a climate catastrophe come from predictions based on computer simulations. Climate is a ‘wicked’ system – very complex with many unpredictable elements. The Scientific Method is the common form of testing an idea or hypothesis to see if it is accurate or true. Check the idea or ideology against the evidence.

Swedish scientist Svante Arrhenius was concerned there would be another Little Ice Age. He began to study how carbon dioxide affects climate. At first he thought that a doubling of carbon dioxide would lead to a large rise in temperature. That’s what many modern sources cite. However, in 1906, based on further research, he changed his view and decided warming would be slight and probably beneficial. (No one read that paper because he only published it in German. Here is the translation.)
So – other scientists began studying the effect of increased human industrial emissions on the environment and developing theories about how carbon dioxide, soot and other greenhouse gases might affect the climate. Some of them prophesied disaster because they envisioned the earth as a ‘greenhouse’ – but in fact the earth is not covered by a glass roof, and many complex interactions take place to reduce the assumed warming effect of carbon dioxide.
