The problem is not as simple as just temperature change. There is a huge worldwide investment based around rainfall following existing patterns. Exchanging 100+million acres of grassland for 100+ million acres of dessert might seem ok if just as much tundra becomes grassland, however rebuilding existing cities in new locations quickly become trillion dollar projects. IMO, preventing climate change is less about protecting the ecosystem as it is protecting existing investments in roads, bridges, dams, houses and factory’s. PS: Toss in even stronger and more frequent extreme weather and dumping CO2 is unlikely to end up as a good thing. At some point in the near future we are simply going to run out of oil so doing nothing does not mean we get to keep up our current approaches for all that long anyway.
