Protecting Our Planet: John Kerry

U.S. special presidential envoy for climate John Kerry says no one nation can solve the climate crisis by itself. The former secretary of state is an advocate of personal diplomacy and is touring Asia ahead of a two-day climate summit hosted by the United States. Kerry is meeting with foreign officials in pursuit of consensus-building around climate change. Kerry joins Washington Post opinions writer Jonathan Capehart to discuss the importance of setting ambitious goals to cut global greenhouse gas emissions by 2030 and how the U.S. plans to lead by example.
