The Polar ice caps are receding. The meen temperatures thought the planet have increased over the past 30 years more quickly than that can be reconciled as "trends" in weather.Too many of you are listening to Sean Hannity on this one.I like him to,I'd rather pay attention to what earth scientists say on this subject,you won't find much disagreement amoung them on global warming.LA for example has done so much to decrease smog,Cal. has always been ground zero for emmissions tech. so well-guided political policies are warranted as well,concerning all enviornmental issues,global warming is (or ought to be) a non-particin issue though. Whether you're for the war or not,like nature or not or ride a fixie or not,unless we want the whole world to look like Egypt,we better do something.You better believe it's happening!
