Global Warming isn't about the Earth getting hotter (something we can easily adapt to cope with), it's about distribution of limited resources.
For 7 billion people to live as we do and enjoy our lifestyle, we need four more Earths.
Doesn't take a genius to realise that the rich must either share, fight, or conserve.
Right now we're being asked (guilt-tripped some might say) to conserve, later on we might be asked to fight because we're shit at sharing.
We'll be asked to fight with those who have the most natural resources - say, someone like Iraq.
Unfortunately, we have a large chunk of the world's resources too ... good thing we've already picked sides.
The least damaging part of "Global Warming" will be the warming part.
EDIT: how big should my hop pot be minimum?
