Prominent Republicans — from former Secretary of the Treasury Henry Paulson to the former chair of the board of Walmart — are urging the White House and Congress to adopt a new market-based plan to address climate change. It establishes a carbon tax and dividend program. But would that reduce emissions? Will Republicans in office go for it? And what would happen to existing environmental regulations? Guests include Ted Halstead, founder, president and CEO of the Climate Leadership Council, Nathaniel Keohane, vice president at Environmental Defense Fund, Chris Mooney, energy and environment reporter for Washington Post, Greg Mankiw, professor of economics at Harvard University, and Kyle Meyaard-Schaap, national organizer and spokesperson for Young Evangelicals for Climate Action.
