Steve Connor, the science editor of the Independent has published an email exchange with Freeman Dyson. I was more struck by what Connor said than Dyson's thoughts. This for example:
As you know these [climate] models are used by large, prestigious science organisations such as Nasa, NOAA and the Met Office, which use them to make pretty accurate predictions about the weather every day. The scientists who handle these models point out that they can accurately match up the computer predictions to real climatic trends in the past, and that it is only when they add CO2 influences to the models that they can explain recent global warming.
And how are the predictions made by these models turning out, Mr Connor?
