What should President Obama say about climate change in his State of the Union address? Actions speak louder than words, but some words will have more resonance and meaning than others.
So we asked scientist Anthony Leiserowitz, director of the Yale Project on Climate Change Communication, to make his suggestion to the president in this extended preview clip from the next Moyers & Company.
In another excerpt, Leiserowitz explains that single-digit degree changes in our climate are comparable to single-digit degree changes in our body temperature when we get sick.
"I think there's an analogy here -- that little difference in global average temperature, just like that little difference in body temperature, can have huge implications as you keep going," Leiserowitz tells Bill.
