As we prepare to watch tonight's State of the Union speech, we're hearing about topics that President Obama is expected to address. Some environmentalists hope he will announce plans to go further in combating climate change.

Tonight's speech comes seven months after Obama delivered his most forceful push yet for action on global warming, in a speech at Georgetown University.

Last summer, The Daily Circuit had a conversation about Obama's proposals for dealing with climate change. We listen back to that discussion ahead of tonight's speech.
