A bunch (maybe 30 or more) of US Senators are going to talk all night tonight about climate change. This will happen on the Senate floor. So far all or most of them are Democrats. Here is a list of who is doing it, with their twitter handle. Also on the list is who is not doing it. And, there are phone numbers too.
Your assignment, should you choose to accept it, is to tweet or call those who are doing it and thank them, and tweet or call those who are not and tell them that they should.
I’m pretty sure this list, at Dail Kos, will be updated dynamically throughout the process.
