"I'm a scientist. I don't 'believe' in anything."

The study of climate science is the cool degree at the university where Dr Diane Cassell is a lead academic in Earth Sciences. At odds with the orthodoxy over the causes of climate change, she finds herself increasingly vilified and is forced to ask if the issue is becoming political as well as personal. Could the belief in anthropogenic global warming be the most attractive religion of the 21st century. What evidence do we need before deciding on policy?
