Sure, there are many effects, some countering. But why believe that
they'll all balance out nicely once equilibrium is reached? The very
variability of climatic history argues against that.

And having a bunch of weird shit happen while waiting for things to
settle down isn't particularly attractive to me either. (Or to the
insurance companies. Aren't they getting more interested in climate
change, since they're the ones who pay for it upfront?)

Is it fertile land for our crops? Does it get good rainfall and
sunlight? Would it make up for extended droughts in the traditional
breadbaskets?
