> 2 degree raise in temperatures globally could be great for food production...

Bear in mind that the 2-degree figure is 2-degrees celcius __average__ global temperature, not two degrees maximum. The oceans are much cooler than land, and the further inland you go the hotter it gets, so at about 2-degrees average warming you've got maybe +3 degrees in Britain, and about +7 degrees Celcius in central USA, which would have catastrophic effects on food production.

Now add in the pressure of vast numbers of people migrating North away from the equator because they're all literally starving, and you've got a formula for civilisation-ending instability.

[EDIT] Also, bear in mind it's two degrees Celcius, which is about 3.6 degrees Farenheit, I've seen American friends get mixed up on that point, misjudging the severity by a factor of almost two.
