Watch as some of the world's leading scientists put the most ambitious geo-engineering ideas to the test in order to tackle global climate change. From covering acres of Greenland's glaciers in protective blankets to constructing space rockets to sending tiny reflective lenses into orbit, these experiments push the boundaries of science and technology by exploring eight creative ideas that just might reduce global warming.   

What if we could solve the problem of global warming by scrubbing the air clean of carbon dioxide? Professor David Keith believes we can do exactly that. He's building a prototype of a machine that will suck ambient air into one end, spray it with sodium hydroxide solution, then expel "scrubbed" air out the other end. Keith thinks he'll prove that his machine will be even more efficient than trees in cleaning CO2 from the air.
