WASHINGTON (AP) — Yes, they're still at it. Some Democratic senators have been talking all night on the Senate floor about climate change and the need for action.

The talkathon started last night around 6:30, and it hasn't stopped yet.

And there's really no debate.

Naysayers and Republicans have largely stayed away. Sen. Brian Schatz of Hawaii says the debate shows that a growing number of senators are committed to working together on global warming even if no Republicans are among them.
