Nowadays there are only a few stubborn die-hards hanging around Internet bulletin boards, and even fewer “real” scientists, who don’t believe that the Earth’s climate is going to hell in a hand basket. But it wasn’t always like that. 30 years ago the fears weren’t about global warming, but rather the dawn of a new ice age. In this 3-part series for BBC Two, popular science presenter Dr Iain Stewart (who brought us Earth – The Power Of The Planet) turns his attention to the climate debate, beginning back then when it all started. When evidence was being pieced together and those in the know were starting to get a bit worried.
It’s pretty clear now that we’ve avoided a new ice age by a mile, so how did the scientists of the seventies get it so wrong? That’s what Dr Iain sets out to find out in this first part of three.
He talks to Dave Keeling – the man who first started taking measurements of atmospheric carbon dioxide way back in 1958, and whose data provided the first real evidence that levels were increasing.
Although concern quickly grew, it wasn’t a message that many people were prepared to believe. In this first episode, Iain also examines the early scientific research into the phenomenon, reveals some of the pioneers of climate-change science, and uncovers secret reports going as far back as 1979. And he blows the dust off the arguments that today’s sceptics are still using, showing that most of them are based on a single, little-known report written in 1981.
