Scared to Death

Scared to Death: From BSE To Global Warming - How Scares Are Costing Us The Earth is a book by Christopher Booker and Richard North. Here's an article from these authors from the Telegraph:

A scare is often set off - as we show in our book with other examples - when two things are observed together and scientists suggest one must have been caused by the other. In this case, thanks to readings commissioned by Dr Roger Revelle, a distinguished American oceanographer, it was observed that since the late 1950s levels of carbon dioxide in the earth's atmosphere had been rising. Perhaps it was this increase that was causing the new warming in the 1980s?

Stage two of the story began in 1988 when, with remarkable speed, the global warming story was elevated into a ruling orthodoxy, partly due to hearings in Washington chaired by a youngish senator, Al Gore, who had studied under Dr Revelle in the 1960s.

But more importantly global warming hit centre stage because in 1988 the UN set up its Intergovernmental Panel on Climate Change (the IPCC). Through a series of reports, the IPCC was to advance its cause in a rather unusual fashion. First it would commission as many as 1,500 experts to produce a huge scientific report, which might include all sorts of doubts and reservations. But this was to be prefaced by a Summary for Policymakers, drafted in consultation with governments and officials - essentially a political document - in which most of the caveats contained in the experts' report would not appear.

This contradiction was obvious in the first report in 1991, which led to the Rio conference on climate change in 1992. The second report in 1996 gave particular prominence to a study by an obscure US government scientist claiming that the evidence for a connection between global warming and rising CO2 levels was now firmly established. This study came under heavy fire from various leading climate experts for the way it manipulated the evidence. But this was not allowed to stand in the way of the claim that there was now complete scientific consensus behind the CO2 thesis, and the Summary for Policy-makers, heavily influenced from behind the scenes by Al Gore, by this time US Vice-President, paved the way in 1997 for the famous Kyoto Protocol.
