Moose are likely doomed south of the Canadian border, the deer population is going to explode. The next tick transmitted disease is likely to be pretty nasty. The maple syrup industry is likely doomed but small-batch production will probably be viable and and you can harvest sap year-round from other species of tree. Lobsters are moving out but blue crabs are moving in. We are going to have a lot of opportunities for sustainable farming because the growing season is going to get a lot longer.

The key word in "climate change" is change. The only thing we can do is try to make what it is going to change into not suck.
