How do we work together to address climate change when there's no consensus on the solution? Host Nelufar Hedayat explores multiple solutions to climate change with Per Espen Stoknes, a Norwegian economist who specializes in the psychology of climate change. She then speaks to Harvard geologist Dr. Daniel Schrag about how the scientific community could improve its messaging. And finally, she talks to former Australian Prime Minister Julia Gillard about the political perils of going big when it comes to enacting green laws.
