While claiming to advocate severe measures to reduce global warming, it appears Al Gore has been contradicting himself on a regular basis. The red spots represent areas where Al, through his sexual escapades, has been heating up the planet on a regular basis. Oregon is home to his "masseuse" , which is what I think they call those kind of girls now. LA is home to his alleged girlfriend and movie co-producer, Laurie David, who has denied the allegations.
The blue-red spots in Tennessee are not the results of Gore's use of carbon offsets, at least not in the typical sense. The red represents the carbon footprint of Gore's 10,000 square foot "house", while the blue represents a blast of cold coming from the master bedroom shortly after details of Gore's other activities surfaced.
