It's interesting that climate zones are shifting so fast that we should probably expect major disruption of forest ecosystems -- probably often as massive die-offs of forest trees. Trees can't lift up their roots (as legs) and walk North or to higher elevations. Smaller plants, of course, can often migrate readily. But some animals are going to have a tough time migrating for various reasons, many related to human artifice such as highways.
