I saw an inconvenient truth a couple days ago... it really shocked me as to how fast these changes are happening and how bad it could be. In the movie it said that both Greenland and Antarctica are losing ice at a rate so fast, that if all of greenland or half of greenland and some of antarctica were to come off and melt, the worldwide sea level would rise 20 feet. real crazy stuff, i know. also, ive been noticin this year that where i live, washington d.c. area, has been unseasonably high in temperature; this problem is worldwide. Bears in europe arent hybernating because its too warm, ive seen a couple cherry blossom trees already blooming, trees becoming green again, etc. In colorado, they just got a huge snowstorm once again, and it wont leave till saturday. i dont know bout the rest of you, but im pretty concerned as to how the earth's climate and seasons will be in the next couple of years if nothing is done about it... really crazy to think about. If you havent seen An Inconvenient Truth yet, defenitely see it, because it will change your outlook on global warming and the Earth's wellbeing as well.
