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?
What if we could remove the global warming problem simply by scrubbing the air clean of carbon dioxides and adding to the greenhouse gases? 2006 Canadian Geographic Environmental Scientist of the Year Canadian professor David Keith, believes he can using a machine which pulls in ambient air, sprays it with sodium hydroxide solution and then releases it back as clean air.
