Kumi Naidoo: As Africa Burns, Why Is U.S. Refusing to Help Stop Catastrophic Climate Change?

The People's Climate March in Washington, D.C., on Saturday came as extreme, climate-fueled weather is already causing havoc across the world. In the U.S. over the weekend, 13 people died as tornadoes flattened homes, uprooted trees and flipped trucks in Texas and in neighboring states. Historic flooding swept away cars, closed interstates and inundated homes across Missouri. Internationally, parts of South Asia are immersed in a sweltering heat wave. In India, heat waves over the last four years have killed more than 4,000 people. At the People's Climate March, we spoke with Kumi Naidoo, former head of Greenpeace, about the new initiative, Africans Rising for Justice, Peace and Dignity.
