“Are they insane?
YES”
NO......follow the money. They all know that GW is a hoax. Don’t kid yourself, they know.
The politicians have been snookered by the scientists on GW theory, and ultimately a lot of politicians are going to be really angry at that cabal of mediocre scientists who mislead them.
But I’ll grant you this: your cynicism about politicians is justified and the number of politicians who know GW is a hoax could be more than I think.
