I'm pretty sure I raised this in a thread a while back. Crop yields have the potential to be higher but increased temperatures could destroy existing crops. Studies suggested raising crops to a higher altitude to get the best of both worlds. Interesting stuff.
Also interesting is that the island nations such as Tuvalu that were supposed to be basically underwater by now are actually growing in size. Scientists were 'shocked' to find that they didn't actually understand how land masses work.

I still think electric cars and other such future technologies are awesome. My concerns are two fold: firstly that coal and oil will be demonised to be point were the developed world will drive itself into poverty and the developing world will go all but extinct, and secondly that developing nations with try to use the UN as a lever to get 'reparations' from those of us in the developed world. A kind of global socialism (a really bad idea).
