Dr Iain Stewart traces the history of climate change from its very beginning and examines just how the scientific community managed to get it so very wrong back in the Seventies.
Episode Two
Dr Iain Stewart investigates the counter attack that was launched by the global warming sceptics in the 1990s. At the start of the 1990s it seemed the world was united. At the Rio Earth summit the world signed up to a programme of action to start tackling climate change. Even George Bush was there. But the consensus didn't last. Iain interviews some of the key global warming sceptics, and discovers how their positions have changed over time.
