Overview

In the second of a two-part documentary, David Attenborough explores just how much climate change is altering our planet. He looks ahead to find out what needs to be done to save Planet Earth from the worst impact of global warming and discovers what could happen to the planet once a 'tipping point' of carbon emissions is reached. He also discusses the solutions we can all adopt to prevent catastrophic change.
