Climate has always changed. It always has and it always will. Ian Plimer offers compelling evidence that our fear of global warming derives from politics and dogma rather than scientific proof, pandering to the current zeitgeist while suppressing information that challenges the popular belief system. Climate change politics, Plimer argues, is religious fundamentalism masquerading as science.

The hypothesis that humans can change the climate is unsupported by evidence from geology, archaeology, history and astronomy. Co2 levels have been higher in the earth’s history and yet did not drive climate change. Climate, sea-level and ice sheets have always changed, but the changes observed today are less than those of the past.

We are certainly facing a global threat, argues Professor Plimer, but it is not the threat of global warming: it is the policy responses to perceived global warming and the demonising of those who dissent.
