Global Dimming

Another example of shriekingly radical climate change discussion on bogus foundations is provided by the 2005 BBC Horizon documentary on Global Dimming.. Focusing on the phenomenon of declining levels of sunlight reaching the earth’s surface in recent years, (between the 1950s and the early 1990s the level of solar energy reaching the earth's surface dropped 9% in Antarctica, 10% in the USA, almost 30% in Russia, 16% in parts of the British Isles) the programme again studiously avoids mention of geoengineering, attributing the rise in aerosol levels in the earth’s atmosphere, with subsequent global dimming, to some unspecified “air pollution” from industrial activity and the burning of fossil fuels, including in aviation.

“Perhaps the most alarming aspect of global dimming” says the programme script “is that it may have led scientists to underestimate the true power of the greenhouse effect….. it now appears the warming from greenhouse gases has been offset by a strong cooling effect from dimming - in effect two of our pollutants have been cancelling each other out. This means that the climate may in fact be more sensitive to the greenhouse effect than thought..”

The strongest warning in the programme on the implications of global dimming (including perhaps the clearest, though still veiled, hints on the factor of deliberate intervention, or “geoengineering”) comes from the climate scientist Peter Cox: “If we carry on pumping out particles it will have terrible impact on human health, I mean particles are involved in all sorts of respiratory diseases…. If you, if you fiddle with the, the balance of the planet, the radiative balance of the planet, you affect all sorts of circulation patterns like monsoons….. it will be extremely difficult, in fact impossible, to cancel out the greenhouse effect just by carrying on pumping out particles, even if it wasn't for the fact that particles are damaging for human health.”

The programme relies heavily for its effect on the proposition that “dimming was behind the droughts in sub-Saharan Africa which claimed hundreds of thousands of lives in the 1970s and 1980s. There are disturbing hints the same thing may be happening today in Asia , home to half the world's population.” “What came out of our exhaust pipes and power stations contributed to the deaths of a million people in Africa , and afflicted 50 million more. But this could be just of taste of what Global Dimming has in store.”

The climate modeller Gavin Schmidt, in no way a climate change “sceptic”, queried the plausibility of this thesis, saying that: “The argument that (global dimming) would lead to huge re-assessments of future global warming, that it was linked very clearly to the famines in Ethiopia, in the 1980s, with the implication that worse is to come, is horribly premature. The suggested ‘doubling’ of the rate of warming in the future compared to even the most extreme scenario developed by IPCC is highly exaggerated. Supposed consequences such as the drying up of the Amazon Basin , melting of Greenland, and a North African climate regime coming to the UK , are simply extrapolations built upon these exaggerations. Whether these conclusions are actually a fair summary of what the scientists quoted in the program wanted to say is unknown. However, while these extreme notions might make good television, they do a disservice to the science.”

Most of the scientists who appeared on the programme proved willing to discuss its style and content and most expressed similar, though more nuanced, objections. Beate Liepert said that “during the research process for the documentary I repeatedly raised my concerns about linking the indirect effect and the Sahel drought.” Graham Farquar said: “The program was not scripted in the way that I would have done. But I guess that you'd have to say that if I scripted it, only my mother would have watched it.” David Travis said: “I believe the Horizons show on global dimming was definitely over-produced and over-dramatized. However, I don't think this is necessarily a bad thing. Without such effects much of the younger audience would likely have lost interest half-way through and the sort of discussions that are going on now would probably not be happening. I did however find myself feeling uncomfortable in spots where statements seemed a bit too bold without sufficient evidence to back them up (even one of my own!). Leo Rotstayn said: I agree that some of the words in the Global Dimming documentary were alarmist. It screened in Australia a few weeks ago, with some changes to the voice over to make it a little less alarmist. It seems to have had a strong impact on many people who saw it, and I have mixed feelings about whether it is justified to be slightly ‘alarmist’ in order to get a strong message across. After all, if I had written the documentary, complete with caveats and qualifications, it would have put most of the viewers to sleep! On the other hand, as a professional scientist, I feel that it is important to be as accurate as possible.”

In a message to Gavin Schmidt, the programme’s producer David Sington said: “I want to refute the notion that Peter Cox, or any other scientist taking part in this or in any other of the films I have made, was "mugged" with trick questions and made to seem to say things he does not believe. …. Dr Schmidt's suggestion is a serious libel (tantamount to accusing a scientist of falsifying his or her data). “The Horizon film” he concluded “was seen by 3.5 million viewers (representing about 7% of the adult population of the UK ) and that copies were requested by the Prime Minister's office. The issues it discussed are being actively debated in Britain .”

From the communications of a number of individuals on both sides of the “climate change” debate it is clear that following the screening of the programme to such a large audience, David Sington was deluged with e-mails from British people concerned about “chemtrails” and/or geoengineering. It is equally clear that he was absolutely determined to keep his distance from the “conspiracy theorists”, even boasting about this to a climate change contrarian who wrote to him to complain about the Global Dimming programme’s sensationalism and “bias”. Having taken receipt of Sington’s ingratiating reply, the contrarian then leaked their private correspondence onto the Internet. Sington could not have been pleased about this. Could he have avoided all these problems by making a different documentary: less sensationalistic, more truthful, more adequate?
