As glaciers melt faster, some scientists are floating bold geoengineering ideas to slow the loss. Students explore how these interventions might work, why critics push back, and what's at stake for coastal communities worldwide.

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. It's for our series, Tipping Point.

This segment is part of a series that explored the scientific study of melting glaciers. Journalist Miles O'Brien traveled with scientists to Antarctica and explored ways those scientists are trying to understand climate change, the history of climate stretching back millions of years and the potential future impact of melting glaciers.
