While the scientific community has reached a broad consensus about climate change and the warming planet, just how well does the general public understand this consensus? In this week's episode of the podcast, Steven E. Koonin is here to discuss what we know about climate change, what we don't, and how we should respond to the warming planet.

Steve is a professor at New York University and a nonresident senior fellow here at the American Enterprise Institute. Previously, he served as the Under Secretary for Science at the US Department of Energy under Barack Obama from 2009 to 2011. This year, he published Unsettled: What Climate Science Tells Us, What It Doesn't, and Why It Matters.
