(CNN) -- In his second inaugural address last month, President Barack Obama forcefully articulated a case for confronting the climate crisis. In his State of the Union speech on Tuesday, I encourage him to lay out a plan on it.
I realize Congress can be an obstacle. A few years ago, the right and left discussed how best to tackle the climate crisis. Today, it has become an article of faith among some conservatives to ignore science and deny there is a human-made crisis at all. Just last week, Sen. Marco Rubio, the oft-touted 2016 GOP savior who will deliver the Republican response to the State of the Union, falsely claimed there was "reasonable debate" on the issue.
