Professor Bob Carter from James Cook University is one of the better critics of the Global Warming argument. I don't call him a 'sceptic' because the issue is not simply a question of a lack of evidence for climate change; there is the prospect of us doing irrevocable harm by adopting 'precautionary' measures to deal with the 'crisis'. The most blatant problem is the misuse of the issue to raise taxes, to further distort the economy. Take a look at his website.
