Breathtakingly broad as its jurisdiction may be, the U.S. Senate does not usually vote on the validity of scientific theories.
This week, it did. And science won. The Senate voted that climate change is real, and not a hoax. The vote was 98-1.
The vote was about an amendment to the bill approving the Keystone XL pipeline. The near-unanimity of the climate change judgment was notable, because so many senators have cast doubt on ideas of "global warming."
