At the start of 2020, Americans were becoming increasingly alarmed about climate change. 

But then: A pandemic, record unemployment and now mass demonstrations over police violence and racism. The last time America faced such a turbulent political moment — during the Great Recession — public concern about climate change fell sharply. Now political winds are shifting again. Is climate still a political priority?

The latest poll from the Yale Program on Climate Change Communication gives us clues. We discuss the results with the program's director, Dr. Tony Leiserowitz. And in this political moment how will Joe Biden and Donald Trump's very different stances on climate play out with voters? We focus on a group that may play a big role in 2020: swing voters. We speak to Rich Thau, a messaging expert who has conducted focus groups with swing voters in battleground states.
