A point that Nad R hasn't gotten. When has global warming happened in the past? http://en.wikipedia.org/wiki/Geologic_temperature_record#Overall_view The planet has had ice ages due to volcanos and possible meteor impacts. When the dust settled, the earth returned to normal temperatures. Because the ice melted does not constitute a global warming, higher than normal temperature.. Global warming can happen because of increased CO2 levels, or increased solar luminance. Heightened CO2 levels have preceded at least 5 GLOBAL MASS EXTINCTION'S.
