Senate Democrats plan all-nighter on climate change

The Senate was headed into another all-nighter Monday evening as 26 Democrats who call themselves the “climate caucus” planned to speak nonstop about climate change from about 6:30 p.m. until 9 a.m. on Tuesday. The talkathon is the latest effort by the group, which is working with a parallel House caucus, to elevate the issue of global warming. The members know that serious climate change legislation stands no chance of passage in this divided Congress, where many lawmakers in the Republican-majority House deny the science of human-caused global warming.
