in some range of temperatures you can find the necessary humidity, temperature, an soil moisture to grow a crop. If we keep moving where that is, then we're constantly searching for new farm land because our old farm land is no longer suitable.
Corn grows on the equator. It's something we'll be growing a great deal of when we face higher global temperatures. But corn fields might have to move to a higher elevation to grow it with some milder temperatures and better rainfall. So you lose a lot of farmland in the plains or North America, especially if desertification were to start occurring.
Everything both of us have gone over sounds terribly expensive. We should probably not do the global warming thing if we can avoid it.
