Lets fight Global Warming

The US space agency is set to launch a satellite that can map in detail where carbon dioxide is in the atmosphere.

Nasa's Orbiting Carbon Observatory (OCO) will pinpoint the key locations on the Earth's surface where CO2 is being emitted and absorbed.

CO2 from human activities is thought to be driving climate changes, but important facts about its movement through the atmosphere remain elusive.

The agency believes the technology on OCO can end some of the mysteries.
