MC, I believe we are in a period of global warming and I feel we(mankind) have a part of the blame to bear. The world historically until the Industrial Revolution had about 1/2 Billion people. With no real industry and all the forests etc etc etc we no longer have. Now there are 6 1/2 Billion without all the good things to help the world. However as the Earth is warming so to is the next planet out in the solar system. Mars is also warming. So it seems as though the sun is helping it along also. I do my part in many ways but you are right.... even a thousand years is but a blink of an eye in the time of global change. Things are changing and neither you or I have the means or wherewithall to stop the changes!
