The atmosphere is our planet's greatest enigma: you can't see it, taste it or smell it and yet it is one of the planet's most spectacular and destructive forces. Dr Iain Stewart shows how the atmosphere has shaped the world we live in and has played a critical role in the development and maintenance of life on earth.

Spectacular photography, big ideas, stunning graphics, jaw dropping locations and Iain's enthusiastic presenting style combine to make this a thrilling exploration of one of nature's most compelling phenomena.
