Neco ke "Great Warming Swindle"
So Friis-Christensen and another author developed yet another means of demonstrating that the Sun is responsible, claiming to have discovered a remarkable agreement between cosmic radiation influenced by the Sun and global cloud cover(6). This is the mechanism the film proposes for global warming. But, yet again, the method was exposed as faulty. They had been using satellite data which did not in fact measure global cloud cover. A paper in the Journal of Atmospheric and Solar-Terrestrial Physics shows that when the right data are used, a correlation is not found (7).
So the hypothesis changed again. Without acknowledging that his previous paper was wrong, Friis-Christensen's co-author, Henrik Svensmark, declared that there was in fact a correlation -- not with total cloud cover but with "low cloud cover"(8). This too turned out to be incorrect (9). Then, last year, Svensmark published a paper purporting to show that cosmic rays could form tiny particles in the atmosphere(10). Accompanying it was a press release which went way beyond the findings reported in the paper, claiming it showed that both past and current climate events are the result of cosmic rays (11).
As Dr Gavin Schmidt of NASA has shown on www.realclimate.org, five missing steps would have to be taken to justify the wild claims in the press release. "We've often criticised press releases that we felt gave misleading impressions of the underlying work", Schmidt says, "but this example is by far the most blatant extrapolation-beyond-reasonableness that we've seen."(12) None of this seems to have troubled the programme makers, who report the cosmic ray theory as if it trounces all competing explanations.
