A lot of damage has been done to the image of geologists in recent years as a result of the appalling behaviour of Ian Plimer and Bob Carter. Both of them have had no compunction about defaming scientists from other fields and lying about research. Although some of the prominent climate deniers around the world come from other fields, there is no doubt that geologists are over-represented.
However, we shouldn’t let this fact damn the whole profession. Even the American Association of Petroleum Geologists has endorsed the IPCC’s work on climate change (although they were the last large scientific organisation to do so). Now Mike Sandiford, a professor of geology at Melbourne University and a siesmologist, has written one of the best opinion pieces I have read on solar power. Go read it.
