General Information：
Science Documentary   published by BBC in 2007 - English narration

Information
Did you know climate change is now so serious that scientists are considering putting a big sunshade in place to keep us cool? Or boosting the ocean's plankton populations to absorb carbon dioxide? The world is being transformed by global warming faster than anyone anticipated. Frozen tundra is melting, giant icecaps are breaking, sea levels are rising and weather patterns are changing. But it's not all doom and gloom; some of the world's most eminent scientists are on the case, in the face of imminent catastrophe. Other plans include shielding the earth from the sun with extra clouds, storing 'artificial trees' underground and using heavy artillery to fire sulphur into the stratosphere. We need to save the planet, fast. And human ingenuity may rise to the challenge.
Climate change is being felt the world over and if global warming continues to increase the effects could be catastrophic. The first three proposed ideas featured in the film, look at reducing the power of the sun - thereby cooling the planet. Professor Roger Angel from Arizona - the designer of the world's largest telescope - is proposing to put a giant glass sunshade in space. Professor Angel's sunshade will deflect a small percentage of the sun's rays back into space.
Dutch Professor Paul Crutzen won the Nobel Prize for chemistry when he discovered the causes of the hole in the ozone layer. His plan is to fire hundreds of rockets loaded with tons of sulphur into the stratosphere creating a vast, but very thin sunscreen of sulphur around the earth.
British atmospheric physicist Professor John Latham and engineer Stephen Salter, have designed a fleet of remote-controlled yachts. These will pump fine particles of sea water into the clouds, increasing the thickness of the clouds and reflecting the suns rays.</br>

Carbon dioxide debate
The other two men in the programme want to tackle the problem of excess carbon dioxide - the cause of global warming. Sydney engineer Professor Ian Jones proposes to feed plankton with gallons of fertiliser. This will make the plankton grow and absorb carbon dioxide from the air. And New York-based Professor Klaus Lackner has designed a carbon dioxide capturing machine and his plan is to locate more of them across the globe. They would suck in carbon dioxide, turn it into a powder and he would bury it deep under the ocean in disused oil or gas fields.
Most of the scientists are reluctant advocates of these ideas, and all believe we should be cutting down on our use of fossil fuels to heat our homes and drive our cars. But is time running out for planet earth?
Although these ideas might have unknown side effects, some scientists believe we may soon have no choice but to put these radical and controversial plans into action.
