That's funny. Given the fact that 'climate change' can mean either getting hotter, or colder, then the answer is nothing. Because the planet ALWAYS swings between getting hotter, and colder, and has since the beginning of time. Global Warming has already stopped. It hasn't warmed since about 1998. It's going to start cooling any year now, and none of this either way, has anything to do with what humans have done. The reason they're now using the term 'climate change' instead of 'global warming' is to cover their as*es, because they've looked at the most recent data, and it shows what I'm talking about, and they know they will look like morons when it's COOLING, if they keep saying "GLOBAL WARMING". But they ARE morons. There was a petition signed this year by 31,000 scientists, many of them Nobel Prize winners, saying that we need to stop this global warming hysteria. That is 31,000 scientists. This is not some 'fringe group of wacko's' or whatever the GW people keep claiming. It's all a myth.
