And, although his methods may be difficult for environmentalists to accept, ecologists believe it may be the first ever case of successful manmade global cooling."

However, I'm glad this relationship of depopulation/carbon emissions didn't come to light during the LAST presidency-- while we may have seen a flip-flop on the right's climate change policies, it wouldn't have ended well. Can't you just see His Royal Highness George II suddenly deciding we needed to invade Iran to save the forests?
Heh heh. You got me all wrong! I believed in global warming the whole time! Save the... uh... whales?
