Global Warming

I have just read on James Delingpole's blog the resignation letter Harold Lewis, Emeritus Professor of Physics at the University of California, sent to Curtis Callan Jr, President of the American Physical Society. Referring to what he calls the global warming scam Mr Lewis states that 'it is the greatest and most successful pseudoscientific fraud I have seen in my long life as a physicist'. Damning stuff and something which I recommend you read. The link is below.
