Climate Talks: The 11th Hour

At the UN climate summit COP21, negotiators are working round the clock to reach an agreement, and an ambitious one at that. Secretary of State John Kerry, White House Science Advisor John Holdren and Greenpeace International Executive Director Kumi Naidoo weigh in on the importance of these climate commitments and of limiting warming to 1.5 degrees Celsius, rather than the 2 degrees usually discussed. Host Steve Curwood speaks with World Resources Institute Global Climate Director Jennifer Morgan about the contents of the final draft text and what makes Paris different from previous climate summits.
