Discovery Project Earth premiered on DISC on August 22, 2008. You've heard the dire warning; you've seen the detailed PowerPoint; you've even bought that light bulb with the swirls, but how about some real action? Now the world's leading scientists meet three uncompromising visionaries to put the most ambitious geo-engineering ideas to the test, tackling global climate change in Discovery Project Earth. From covering acres of Greenland's glaciers in protective blankets to stop it from melting to constructing space rockets to send tiny reflective lenses into orbit to planting thousands of saplings via a mass aerial drop to reforest barren areas, these are experiments on an epic scale. Each one will push the boundaries of science and technology, but will they produce groundbreaking environmental results?
