Very often the reason we don't die from these things is because we take precaution. Imagine we had done nothing against ebola or aids, we'd have millions of deaths by now. (In the case of aids, not all places were so lucky [0].)

Same for the ozone hole, or dying trees from acid rain. When the source of the problem is identified, we can fix it, and that's the case for greenhouse-gas-caused climate change.
