It is a shame that they took the movie off. There were a number of scientists on there including a founding member of Greenpeace.
The main points that they argued is that the CO2 rise that Algore referred to was after the earth warmed and was caused by oceans releasing CO2. It is a fact that the solubility of CO2 decreases with increasing temperature. They also pointed out that the main greenhouse gas is water vapor and that CO2 is a relatively small contributor.
The earth was much warmer before the little ice age hit. We had been warming up from that and the majority of warming in the 1900s took place before 1940, then we cooled down (they were talking about the next ice age in the mid 70s) before warming again. Since 1999 we have been cooling.
There is no need for scientific consensus if you can prove your theory, but they can't. You can worry about scientists paid by oil companies, I worry about the ones paid by government.
