Debate on the Green Party climate list about what to to with climate change deniers. I have spent time on OpenDemocracy.net clashing with these guys. They are very troll-like, utterly dogged, and work by seizing on some fact or factoid, and presenting it as the clinching piece that will overthrow the thousands of papers by serious climate scientists who have arrived at consensus that climate change is caused my our emmissions, climate change is very serious indeed, more serious than terrorism, and that we should have a technological revolution in the way we source our energy.
This view is a threat to the oil industry, and also to the particular form of capitalism advocated by free market fundamentalists. George Soros uses this term, and it identifies that it is close in many ways to a religion, based on the philosophy of individualism. I find that the strictest adherents are the libertarians.
One characteristic of this movement it its use of insult instead of argument.
It is tempting to ignore their rantings, because talking to them is like trying to discuss literature with someone who cannot read. But if we leave them alone, they will influence many good people with their idiosyncratic theories.
The evidence that climate change is not a theory, but a fact, is here.
