First off, I have no doubt that global warming is a fact. But, considering that the glaciers that once covered most of North America were seriously melted before mankind learned how to make fire, I do doubt that blaming it all on un-natural causes is anything more than Ermal whining, "Did I do that?". Mankind claiming to cause global warming is nearly as big an ego trip as assuming that the universe rotates around the earth. Let's face it, there have been some really big temperature swings on this planet over the millenia and the most we could do is help it along just slightly.
