BBC Earth The Climate Wars 1 of 3 Battle Begins
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. Along the way he uncovers some of the great unsung heroes of climate change science, and introduces us to a secret organisation of American government scientists, known as Jason, who wrote the first official report on global warming as far back as 1979.
He shows how - by the late 1980s - global warming had already become a serious political issue. It looked as if the world was uniting to take action. But it turned out to be a false dawn - in the 1990s global warming would be transformed into one of the biggest scientific controversies of our age.
