This is dumb. I thought he was going to show a chart that showed that humans are responsible for it, not that most scientists agree. A few centuries ago they just asked the Pope, simpler process.:)

They are two types of deniers: we have the earth is not warming type, "Look it snowed in Colorado, we're warming uh?" and two those that say it's a natural process and point to the charts where earth went through cycles on it's own over the millions of years.

(Personally I buy the CO2 layer that act as a sheet acts on us during the night.)
