LONDON: A documentary titled The Great Global Warming Swindle will be aired on British television by Channel 4 Thursday highlighting that claims global warming is manmade constitutes the ''biggest scam of modern times.''
The documentary dismisses outright the claims that greenhouse gas emissions caused by human activity leads to climate change. Instead, it says the Sun is the real cause for global warming.
Directed by film maker Martin Durkin, the documentary disputes the scientific opinion professed in the recent United Nations report, which has said humans are very likely to blame for global warming and that there is no doubt remaining that it is caused by man's use of fossil fuels.
Durkin says the argument of man-made climate change is a lie and the biggest scam of modern times. He describes global warming as "a multibillion-dollar worldwide industry, created by fanatically anti-industrial environmentalists, supported by scientists peddling scare stories to chase funding, and propped up by compliant politicians and the media."
Durkin also says with the argument that global warming is man-made getting predominance, several other reasons for climate change are getting sidelined.
The film lines up leading scientists who claim that there is little scientific evidence to support the theory that global warming is a result of man-made greenhouse emissions. They argue global warming could be caused by increased solar activity such as a massive eruption.
Prof Ian Clark, an expert in palaeoclimatology from the University of Ottawa, insists that global warming could be caused by increased activity on the Sun and that ice-core samples from Antarctica show that warmer periods in Earth's history have come about 800 years before rises in carbon dioxide levels.
These argument is, however, counter to the work of several scientists, who have used similar ice-core samples to illustrate that raised levels of carbon dioxide in the atmosphere have accompanied the various global warming periods.
The documentary also tells how after the Second World War there was a huge increase in carbon dioxide, but temperatures have subsided for four decades after 1940.
Philip Stott, emeritus professor of biogeography at the School of Oriental and African Studies in London, says climate change is a complicated issue. He says it cannot be said that just one factor can lead to the greenhouse effect.
Another scientist appearing in the documentary is Paul Reiter of Paris' Pasteur Institute. He is an expert in malaria and described the U.N. report a "sham." He says, it included the names of several scientists, including him, who disagreed with the report.
Reiter says his name was removed only after he threatened legal action against the panel.
