Ah yes, the loony Senator from Exxon, James Inhofe. What a surprise.
This is off topic but it speaks to the mental condition of the primary source for your ridiculous 50 billion assertion:
In March 2002, Inhofe made a speech before the U.S. Senate that included the suggestion that the 9/11 attacks were a form of divine retribution against the U.S. for failing to defend Israel. Among other things Inhofe has said, "I believe very strongly that we ought to support Israel, and that it has a right to the land, because God said so."
Because "God said so"? LOL
If this is the best you can come up with, you've lost the argument.
I've been trying to look closer into this 50 billion figure, but though it's thrown around a lot, it's hard to pin down. Seems it includes, research, estimated cost (losses) of cutting greenhouse gas, and anything remotely connected with global warming. It can hardly be equated with the almost direct pay offs Exxon has made to your "scientists."
