Bill McKibben to Jerry Brown: We Must Keep the Oil in the Soil, Limiting Emissions Is Not Enough

Governors, mayors and policymakers from around the world are gathering this week for the Global Climate Action Summit. The conference was organized by California Governor Jerry Brown. The conference begins today, just days after Brown signed a new law to shift California to 100 percent carbon-free electricity by 2045. While Brown is hailed as a climate hero, he has been widely criticized by many climate justice activists who are planning to protest outside the opening of today's conference. We speak to Bill McKibben, the co-founder of 350.org. His latest piece for The Nation is titled "Jerry Brown's Climate Legacy Is Still Being Decided."
