The miners have set up a think-tank called the Lavoisier Society, which claims to be promoting debate on global warming, but its public activities suggest it exists to promote the idea that global warming due to human activity exists mainly in the imagination of environmentalists rather than being scientific fact. I think it is fair to say climatologists have a better record predicting the weather than economists have predicting economic events. The fundamental reason is that weather forecasts are based on scientific laws that do not change through time. This means it does not matter at what date a scientific experiment is done. The experiment can be re-created and the conclusions checked.
