Satellite technology has enabled us to understand the importance of the oceans in storing heat energy and regulating climate. Research scientist Lee Lueng-Fu explains how a Satellite was able to track the development of the El Nino affect for the first time. El Nino caused weather events around the world - droughts, bushfires, storms. The latest generation of Satellites are now used to improve climate change models. Computer graphics of Satellite images show effects of climate change.

The history of weather forecasting and early satellite programmes is told using archive film, highlighting the difficulties associated with a lack of weather data. 200 dedicated weather satellites have been launched since the 1960's. Together, these satellites enable us to monitor every weather system around the world and to see the weather as it approaches. Interview with meteorologist Ewen McCallam who is using a sequence of satellite images to identify a warm front, he goes on to describe how geostationary and polar orbiting satellites are used. Weather prediction can save lives, especially in tropical regions as information from satellites is used to track hurricanes as they develop. Computer models are shown following a storm over Africa developing into a hurricane over the Caribbean.

"The UK may have become dangerously over-reliant on satellite-navigation signals, according to a report from the Royal Academy of Engineering."

"GPS location apps on a smartphone can be very handy when mapping a travel route or finding nearby events. But how does your smartphone know where you are? Wilton L. Virgo explains how the answer lies 12,000 miles over your head, in an orbiting satellite that keeps time to the beat of an atomic clock powered by quantum mechanics. "
