In this episode, a conversation with United Mine Workers of America President Cecil Roberts about climate change and coal. As President Biden announced a goal to halve U.S. global warming emissions, Roberts had a message of his own: he will not accept further job losses in the coal sector. Reporter Curtis Tate explains the complicated politics around Biden’s climate agenda. And we hear from a former Kentucky coal miner who made a power switch of his own, from mining underground to using energy from the sun.
