"There is no single piece of evidence that proves that a given amount of CO2 increase should cause a large increase in temperature. You may say, 'just a second, we all saw Al Gore's movie, in which he presented a clear correlation between CO2 and temperature from Antarctic ice cores.' Well, what he didn't tell you is that one generally sees in the ice cores that CO2 lags the temperature by typically a few hundred years, not vice versa. The simple truth is that Al Gore simply showed us how the amount of CO2 dissolved as carbonic acid in the oceans changes with temperature. As a matter of fact, over geological time scales, there were huge variations in the CO2 (a factor of 10) and they have no correlation whatsoever with the temperature. 450 million years ago there was 10 times as much CO2 in the atmosphere but more extensive glaciations." Israeli scientist Dr Nir Shaviv, rebuts climate alarmisn in Cambridge Union debate.
