A climate shift like global warming might have a dramatic impact on our population, but it wouldn’t be the first time the temperatures were high. We have all heard about the tropical age when dinosaurs were alive, so what we are potentially facing is far from new.
There have been many geological ages in our long history, and I am quite certain not all of them were influenced by pollution and automobile exhaust. While I completely agree that the way things are going now are not good and need to be changed, I don’t think the sky is falling simply because we have a lot more cars on the road or we burn wood in our homes.
Perhaps global warming, if indeed it exists, is simply nature continuing on the path it was already headed. Ice caps came, and ice caps may go away, but they weren’t always here and the planet did just fine when they were gone before.
Things need to change, but the fate of all mankind does not rest on the back of a super efficient electric car or a reduction in industrial output, although those two things would be very nice.
