Democratic senators intend to occupy the Senate floor from Monday night at 10 P.M. ET through Tuesday morning at 9 A.M., taking turns speaking to urge action on climate change.

The event, organized by Sen. Brian Schatz (D-HI), features 28 Senate Democrats, including the top four leaders and members of the Senate Climate Action Task Force.

“Climate change is real, it is caused by humans, and it is solvable,” Schatz said. “Congress must act.”

Legislative action on climate change has been seen as a lost cause since Republicans won the House majority in the 2010 elections. In 2009, the Democratic-led House passed a sweeping climate bill but the Democratic-led Senate took no action. As a result, President Barack Obama has sought to address the issue via executive actions where he can. The scientific community overwhelmingly believes climate change is being exacerbated by human activities like burning fossil fuels.

The talk-a-thon won’t disrupt any Senate business as the chamber would probably not be in session during that time. They intend to broadcast their efforts on social media with the hashtag #Up4Climate.

Majority Leader Harry Reid, D-Nev.
