In Episode 1: A Changing World, we see the changes that are upsetting the scientific predictions of the impact of climate change on the Arctic. Now, one sobering forecast is that the Arctic Ocean will be seasonally ice free by the summer of 2013. This possibility is what drives environmentalists to identify ways to minimize the changes affecting this snowy land. But for prospectors like Gordon McCreary, climate change brings new opportunities. He is part of the rush to claim the riches beneath the Arctic's ice: deposits of metals, gold, diamonds, and oil and gas.
Geologist Prof Iain Stewart shows how the continent of Africa was formed from the wreckage of a long lost supercontinent. He discovers clues in its spectacular landmarks, mineral wealth and iconic wildlife, that help piece together the story of Africa's formation. But he also shows how this deep history has left its mark on the modern day Africa and the world.
As climate change begins to feel like an impossible challenge, this documentary tells the story of the first man-made threat to the planet's environment - the hole in the ozone layer - and how the world managed to fix it. The scientists and politicians at the heart of the story reveal how they spotted the giant hole in the stratosphere and, against all odds, persuaded Ronald Reagan and Margaret Thatcher - two of the most unlikely eco-warriors in history - to take action.
