It was a lot of hot air about a lot of hot air. Democrats took to the Senate floor Monday night to talk about global warming and did not let up until morning.
"Climate change is real, it is caused by humans, and it is solvable," said Sen. Brian Schatz, D-Hawaii.
Despite that bravado, Democratic leaders made it clear they have no plans to bring a climate bill to the Senate floor this year. Indeed, the issue is so politically charged that a host of Democrats who face tough re-election fights in the fall opted to skip the session. Sens. Mary Landrieu of Louisiana, Mark Pryor of Arkansas, Mark Begich of Alaska and Kay Hagan of North Carolina were among Democrats who stayed away.
