Senate Democrats are about to burn the midnight oil to make their case on climate change.  

The previously rumored all-night session on the effects of climate change will take place Monday, Sen. Sheldon Whitehouse confirmed.  

“It’s locked in,” the Rhode Island Democrat told CQ Roll Call. “An all-nighter is an all-nighter. We’re going to go all the way through to eight or nine in the morning or whenever they need to clean it up for the next day.”  

That would clearly meet the established definition of an all-night session.  

Sen. Brian Schatz, D-Hawaii, and Whitehouse are coordinating the campaign.  

Whitehouse has given weekly floor speeches when the Senate’s been in session for well over a year now, a series he’s dubbed “Time to Wake Up.”  

The Rhode Islander is also heading to Iowa, where he wants environmental policy to be an issue at the state’s key caucuses in 2016, the Des Moines Register reported .
