We really need to stop arguing whether Global Warming will wipe out the human race or not; because it won't. The only things that will wipe us out are: Solar radiation on a planetary level (many different scenarios) Celestial impact Yellowstone erupting (or an equally large volcanoe) Even a Yellowstone eruption might not necessarily wipe us out, but it'd sure do more damage than Global Warming ever will. Global Warming is more of a lifestyle change than anything. Drastic changes? Likely, but they still remain just that.
