I agree - climate change is a big deal. In fact, it doesn't even matter what our CO2 output is with respect to this problem -- even if we cut it off completely we still have to brace for the threats of climate change. Coming Ice Ages and warm periods could have potentially devastating effects, and we need to be ready. That said, I don't think the temperature will change significantly overnight so we have some time to prepare.
