Quote:No, but it shows that climate can change without human intervention. The mere fact that it is slightly warmer now than it was in 1979 (the first year with actual GLOBAL measurements) is not proof that manmade CO2 has any effect on the climate. Physics predicts an effect, but that's in the laboratory. There are numerous confounding factors in nature. The fact that the global temperature hasn't changed since 2000 proves that other effects are at least as strong as CO2 in determining global temperature.
