Global Warming?  

My opinion on glabal warming is of course it's real, it's serious, we've gotta do something about it. Tho recently I have talked to people who have said they don't believe in global warming. They have said it is just another one of the earths cycles. I have seen many movies, and read many articles, even in the local news paper that these same people read, about global warming and it's current effects. I live in NY and this past december 1st we had our first tornado warning in years. On DECEMBER 1ST! This is alarming to me. This was alarming to my little brother in texas who after i told him we had a tornado warning said "in winter?". Yes strange. I've heard people say "o just wait, it's just saving up," What's saving up? If it "saves up" to long what'll happen? It scares me to think about what it'll be like here in 20 years. Will it still snow in winter? Will summers be to hot to take?
Should i move to Canada? What's your opinion? I'd like to hear from both sides so any opinion is wanted, an opinion is an opinion after all.
