Hmmm.. People forget the Main Factor of what causes warming --- our pollution. If we stayed at the current level of pollution then it will get worse, and the fact is as the world grows the amount of pollution will grow enormously without checks and controls. Cutting back the CFCs (I believe they were) from being released into the atmosphere has already had a large effect on letting the ozone repair; if that check wasn't put in there it would be much worse, and the Earth would be warming up more already.
If Global Warming was at the 'crisis level' that seems to need to exist to get anyone off of their ass then shit would already be hitting the fan and it would be too late before a lot of life died.
