Sen. Amy Klobuchar (D-Minn.) asked unanimous consent to pass S.Res. 524, which is a measure that expresses the sense of the Senate that climate change is occurring and poses a risk to the United States. But Inhofe objected.

Inhofe has been an ardent climate change denier, saying it is the “biggest hoax” perpetrated against mankind.

“To say that we have no warming is just not factual,” Whitehouse said. “Ignorant, out-of-touch or crazy — that’s what young Republicans think of that position.”

Klobuchar said she would try again to pass the resolution because the Senate looks “silly” for ignoring scientific agreement.
