Are you all sure it is Global Warming or will it be the Global Cooling that quickly follows it. Throughout history this Earth has gone thru warming, cooling, warming etc. Atmosphere warms up seas rise coastlines shrink, glaciers form, coastlines extend. There is only so much water on this planet. Right now the glaciers in North America are almost gone, in 75-200 years they will be gone, what can we do, buy a few more years in 200 the seas will be at their new heights no matter what. Then after a few thousand years it will begin to get cold again, the ice will form and start heading south again. Canada will probably be in Virginia then we start all over again. What I am saying is that it all has happened before and will happen again. Man can only blow up the world, not change nature permently.
