According to a scoop from the Washington Examiner, Florida Senator Marco Rubio is the latest Republican to join the Senate Climate Solutions Caucus. He joins colleagues Mitt Romney, Lisa Murkowski, and Lindsey Graham in getting behind caucus co-founder Senator Mike Braun. Braun and Senator Chris Coons recently launched the bipartisan effort and have already been holding meetings.

Back in August, Rubio said Floridians “must confront” climate change but suggested the focus shift from plans to reduce carbon emissions to adaptation. “Attempting to reverse engineer the U.S. economy to absolve our past climate sins — either through a carbon tax or some ‘Green New Deal’ scheme — will fail,” he wrote in an op-ed published in USA Today.

As the caucus holds more listening sessions with experts and stakeholders, perhaps he will shift his thinking on solutions.
