And this article is written by someone promoting his own book - talk about someone whose comments are linked to his income!!? I think Ian Plimer would be amused to know he is supposedly linked to millions of dollars in mining investments! One reason geologists are sceptics is that we see past tiems when there were ice ages and the CO2 concnetrations were in the thousands, not hundreds, of ppm. The Vostok ice cores show that temperature rises 800 years BEFORE the CO2 rises, consistently in 4 cycles over the last 450,000 years. Makes a mockery of "cause and effect'! Just because a two-axis graph shows a correlation between two variables doesn't mean one causes the other - Ian Plimer pointed out teh rises in global temperature shows a direct correlation with the number fo pirate attacks in the Malacca Straits - but no cause and effect!
