I think they should run with the “Giant Mirrors” idea myself. Putting gas suppressing diapers on cows is another great idea, as well as powering cars with cow “emissions”.
But they had better hurry, MANBEARPIG says that the ice caps will be completely gone in just 5 years. I suggest they panic and begin voluntary euthanasia among those who believe this insanity. That would be the very BEST solution to this problem. Starting with ALGORE.
