Global Warming

Global warming is becoming a part of our everyday lives nowadays. People are buying hybrid vehicles trying to keep energy cost down and go green. Buses are becoming "green" buses and the is a race to find alternate feul. At a meeting at the UN studies showed a trend of warming over the last 50 years, and its very likely that humans are a cause. The only change from a 2001 report is the word very. I think that that one word has caused more people to be involved and be aware of global warming. I also think that there are studies that show that global warming is not really a new thing, but that is like a cycle. The earth has had warm periods, and then gone into an ice age. Whatever the case, everyone should be aware and try to go "greener", not just to save our planet, but to increase living circumstances, and air quality and all that good stuff
