Climate policy under a second Trump presidency

This year is on track to be the hottest on record. States in the southern part of the United States are still recovering from a pair of devastating hurricanes. Scientists say we are seeing the effects of climate change happening before us in real time.

All of this as a new administration takes the reins in a country that’s among the largest greenhouse gas producers. President-elect Donald Trump has called climate change a hoax and has led his supporters in chants of “drill baby, drill.” But just how much can a president do — or undo — when it comes to environmental policy?

Our guests this hour are Michael Mann, Professor of Earth & Environmental Science at the University of Pennsylvania, Director of the Penn Center for Science, Sustainability and the Media and author of Our Fragile Moment, and Coral Davenport, a New York Times reporter covering energy and environmental policy.
