Gore repeatedly labels carbon dioxide as "global warming pollution" when, in reality, it is no more pollution than is oxygen. CO2 is plant food, an ingredient essential for photosynthesis without which Earth would be a lifeless, frozen ice ball......and there's three more pages where that came from.
In fact, the correlation between CO2 and temperature that Gore speaks about so confidently is simply non-existent over all meaningful time scales. U of O climate researcher Professor Jan Veizer demonstrated that, over geologic time, the two are not linked at all. Over the intermediate time scales Gore focuses on, the ice cores show that CO2 increases don't precede, and therefore don't cause, warming. Rather, they follow temperature rise -- by as much as 800 years. Even in the past century, the correlation is poor; the planet actually cooled between 1940 and 1980, when human emissions of CO2 were rising at the fastest rate in our history.
Similarly, the fact that water vapour constitutes 95% of greenhouse gases by volume is conveniently ignored by Gore. While humanity's three billion tonnes (gigatonnes, or GT) per year net contribution to the atmosphere's CO2 load appears large on a human scale, it is actually less than half of 1% of the atmosphere's total CO2 content (750-830 GT). The CO2 emissions of our civilization are also dwarfed by the 210 GT/year emissions of the gas from Earth's oceans and land. Perhaps even more significant is the fact that the uncertainty in the measurement of atmospheric CO2 content is 80 GT -- making three GT seem hardly worth mentioning.
If Algore really wants to stop global warming, he should personally stop producing so much hot air.
