I may be wrong about it and if I am I will be sad, but the people making these predictions haven't done too well so far. I'll accept global warming, I've seen the changes in my lifetime, but the changes haven't been that it gets terribly hot in the summer nor is it a lot warmer in winter. The change I've seen is in the length of the growing season. When I was first married we raised a garden. We knew that to plan green beans before June first was folly, as most years it would freeze them off about the 10th and we'd have to replant. We also knew that we had to be ready to cover tomatoes in mid-august to keep them from freezing. Now we could plant our beans in mid-may and have tomatoes ripening into September. During that 30 year span, we had record cold too. That doesn't work well for the plants that would migrage north. We've had bad droughts that killed some trees, but we've also had record rainfall too. The only thing I've seen that would indicate a change of the type of trees growing here is the infestation of the pine beetle that is killing the vast acreages of jack pine. This may be a perennial problem, or it may pass. I hope I live long enough to see if the prediction is right or wrong.
