In winter 2006-7 it was the first time that I saw rain in Saint Petersburg and Moscow, Russia past the month of November. In fact, that and the following winter were both so unusually warm, that no snow was seen until late January. Snowboarders were really unhappy to travel almost all the way to Arkhangelsk to see it. Actually, only this summer enough ice in Greenland melted to show that global warming is happening a lot faster then scientists originally thought. Thank you for those, who express doubts, but, unfortunately, GB is a fact that has been proven wrong only by that research that was payed for by Exxon http://members.greenpeace.org/blog/exxonsecrets . For anyone who has studied even the basics of physics and chemistry, GB should not be a problem to grasp. If you are having trouble with that, please see chapter one of your biology textbook from fifth grade.
