An excerpt from this post:

...If the CO2 were the cause, if the temperature were its consequence, and if the greenhouse effect were able to transform a 100 ppm increase of CO2 into 8 degrees of warming as suggested by Al Gore, something like that would have happened since 1850, too: since 1850, we have increased CO2 by additional 100 ppm. But the temperatures clearly didn't increase by 8 Celsius degrees since 1850. That's why we see that the prediction for the recent temperature change by the hypothesis that CO2 was a major climate driver during the glaciation periods is brutally falsified. The observed warming is 13 times smaller than the prediction.
