Guest : Kevin Noone February 6 2011

Proposals to cut carbon dioxide emissions have generated a great deal of controversy for well over 20 years. The next great debate in the struggle to contain climate change is just beginning.

Schemes to deliberately control global climate through large-scale technological interventions – known as geo-engineering – have recently received greater attention from scientists, policy makers and the media. Such schemes would, according to proponents, fill the void created by the failure of global society to reduce emissions, and instead use various means to deflect incoming solar radiation or manipulate ecological processes to sequester large amounts of carbon dioxide. The risks associated with intervention on such a planetary scale, however, are vast.

This Sunday, Think Globally Radio goes in-depth on the scientific and ethical considerations of geo-engineering with Prof. Kevin Noone, a climate scientist at the Dept of Applied Environmental Science and Stockholm Resilience Centre. This will be the first of two episodes devoted to geo-engineering, an issue in its infancy that promises to attract controversy for years to come.
