What we will see from AGW is things like rivers drying up yet not being replaced elsewhere. This type of thing will kill arability.
I think it's hard to argue that global warming improve arability anywhere, even if it decreases the amount of arable land in the world as a whole. That's not what I meant by adaptation though, I meant that we'll need another green revolution so we can grow crops on land that currently isn't arable. Most of the world's crops are grown on land that was considered useless before technology turned it into good cropland. I'm convinced that the answer to global warming (and famine in general) is to engineer new breeds of crops that are resistant to drought, flooding, changes in temperature, or whatever else happens to the climate. If I had to start my education over again, I'd probably pursue this area of research as a career because I think it's the most important research being done in the world today, but whatever, I'm happy with what I'm doing now.
