Australian geologist, Professor Ian Plimer:
“No one has yet shown that human emissions of carbon dioxide drive global warming, and if they did, they’d also have to show that the natural emissions—and that’s 97% of the total—don’t drive global warming.”
“Then I look back in time through my geological eyes, and look at times in the past when we have very high carbon dioxide contents of the atmosphere, up to hundreds of times higher than now, and we see that we didn’t have runaway global warming… But what we did have is six major ice ages, and there is no correlation over geological time between carbon dioxide in the atmosphere and temperature.”
