New Climate Solutions Sought as CO2 Levels Rise

Levels of carbon dioxide in the Earth's atmosphere are rising faster than predicted, researchers say. Also, carbon sinks — places that take CO2 out of the atmosphere — aren't absorbing the gas as well as they used to. Several new papers propose new ways to combat global climate change.

Guests:

Eileen Claussen, president of the Pew Center on Global Climate Change

Christopher Field, director of the department of global ecology, Carnegie Institution of Washington; professor of biology at Stanford University

Steve Rayner, professor of science and civilization and director of the James Martin Institute at University of Oxford; member of the Royal Commission on Environmental Pollution
