Scientists explore large-scale geoengineering to slow glacier melt

At a time when the impact of climate change is undeniable, some researchers suggest we need to start work on far more ambitious approaches for tackling these problems. These proposals are often referred to as geoengineering. Science correspondent Miles O'Brien looks at one such concept to deal with the melting of glaciers and sea ice.
