Going Green: Secrets in the Ice
Saturday, 8pm, CNN This succinct 30-minute documentary about Greenland’s fast melting ice was pulled from the CNN schedule last week at short notice because of the network’s on-the-ground coverage of events unfolding in Gaza. Rescheduled to tonight, Going Green: Secrets in the Ice explains how Greenland’s ice, the second largest ice mass in the world, is melting fast, exposing its people and wildlife to an uncertain future. To the naked eye, the ice mass seems unmoving, but some beautiful time-lapse photography shows a landscape constantly in motion. The rate of the melt is frightening. The Arctic ice shield is receding by about 300sq km a year. Some fear the melting process could reach a point of no return and that this ice could disappear completely. If that happens, sea levels will rise 7m worldwide. Then it’s goodbye Sydney, Waikiki, London, Bangkok, New York, Shanghai and Mumbai. And the good news? This could take thousands of years. The real point of the exercise here is for a team of scientists to run radar surveys of the ice shelf from their specially modified plane, and stop along the way to dig ice cores. These reveal much knowledge about the rate of melt in the past and allow better informed predictions to be made about the future.
