The reason the Sahara is not a rich agricultural region is not because it's hot, but instead because it's dry. What's lacking that you need to grow plants is water. And rainfall does tend to reduce temperatures somewhat. To add to your very informative post...Global warming will not have a uniform effect around the world. It may make some places less inhabitable, but these would be offset by the northern climes that become more agriculturally productive and generally more habitable. (going south, it would take a whole lot of global warming to make the antarctic more habitable, so we can leave it out of the equation). Global cooling might actually make some areas more habitable, but this would be negatively offset by much larger regions that could no longer support large populations. So let's go back to the worst case scenario where the polar bears all drown because the pack ice that they were hunting on melts overnight while they are hundreds of miles from land. How many species would be brought back from the brink of extinction due to the warmer and wetter climate? I can think of three or four right here in california that are doomed if we don't get some climate change pretty darn soon. As a species, does the polar bear have any greater inherent value than Death Valley's Devil's Hole Pupfish or the Riverside Fairy Shrimp??? One thing that the climatologists didn't include in their models was the albedo effect of increased cloud cover. Mother Earth really is an incredible organism. So many self regulating mechanisms like plants that will thrive in a CO2 rich environment and thus remove CO2 from the atmosphere and clouds that increase when the planet becomes warmer, thus reducing the amount of solar energy that reaches the surface.
