Earthbeat looks at ‘Geoengineering.’ Scientists around the world are considering ways to stop global warming by shielding us from the sun itself. These schemes were once thought to be wacky, dangerous, or downright impossible, but now, even a noted Nobel-prize winner says they may be necessary to keep the Earth cool.
Host Mike Tidwell speaks to Ken Caldeira of the Carnegie Institution in Stanford, California about the politics behind geoengineering.
Mike MacCraken of The Climate Institute will discuss the science behind the various suggestions of shading the Earth.
Michael Oppenheimer is the professor of Geosciences and International Affairs at the Woodrow Wilson School at Princeton University, and Alan Robock is a the associate director of Center for Environmental Prediction at Rutgers University. They’ll discuss the feasibility of geoengineering.

The purple layer is the troposphere containing smoke from landclearing biomass burning.
