I think the food prices have more to do with the oil companies than global warming specifically. It's getting expensive to have the goods distributed. I know a lot of crops didn't do well this year, but some crops have done well. Like pecans. We'd end up with a glut long before we lose the ability to produce enough food.

I saw a story in the news about two college kids who took 1k and made their crappy Toyota Prias get 100mpg highway. Do you really think auto manufacturers don't have the technology to build more fuel efficient cars? Someone's in bed with the oil companies.
