I guess they haven't heard that Europe has cancelled global warming due to the expected onset of a mini-ice age there.
Also, NASA has determined that methane is NOT produced soley as a by-product of burning fossil fuels. They have confirmed that Saturn's moon Titan has bunches of methane and no known fossil fuel source or evil SUVs to cause "GW".
Maybe they can come walk in Las Vegas where we have just had the coldest November in history. (averaged only 59 degres highs). Or maybe the people in Missouri or Kansas would like a few thousand people warming things up for them. Can I get a shout out?
