This programme delves into a world lying beneath a frozen surface. It is the greatest climate disaster ever to have hit Earth - 650 million years ago, a cataclysmic ice age sealed the entire planet beneath ice and snow, almost destroying life and turning the world into one huge snowball.
Snowball Earth uncovers the story behind one of the most controversial theories in science today. To investigate, the programme travels the world to follow scientists scouring southern Australia, Nevada's Death Valley and Alaskan glaciers for tantalising clues as to how our planet ran away into this doomsday scenario. The results could improve understanding of evolution and survival of life.
