Why I would rather be called a heretic on global warming


David Bellamy in The Times, London, 21 October 2007


Am I worried about man-made global warming? The answer is “no” and “yes”.

No, because the Hadley Centre for Climate Prediction has come up against an “inconvenient truth”. Its research shows that since 1998 the average temperature of the planet has not risen, even though the concentration of carbon dioxide in the atmosphere has continued to increase.

Yes, because the self-proclaimed consensus among scientists has detached itself from the questioning rigours of hard science and become a political cause. Those of us who dare to question the dogma of the global-warming doomsters who claim that C not only stands for carbon but also for climate catastrophe are vilified as heretics or worse as deniers.

I am happy to be branded a heretic because throughout history heretics have stood up against dogma based on the bigotry of vested interests. But I don’t like being smeared as a denier because deniers don’t believe in facts. The truth is that there are no facts that link the concentration of atmospheric carbon dioxide with imminent catastrophic global warming. Instead of facts, the advocates of man-made climate change trade in future scenarios based on complex and often unreliable computer models.

Name-calling may be acceptable in politics but it should have no place in science; indeed, what is happening smacks of McCarthyism, witch-hunts and all. Scientific understanding, however, is advanced by robust, reasoned argument based on well-researched data. So I turn to simple sets of data that are already in the public domain.

The last peak global temperatures were in 1998 and 1934 and the troughs of low temperature were around 1910 and 1970. The second dip caused pop science and the media to cry wolf about an impending, devastating Ice Age. Our end was nigh!

Then, when temperatures took an upward swing in the 1980s, the scaremongers changed their tune. Global warming was the new imminent catastrophe.

But the computer model – called “hockey stick” – that predicted the catastrophe of a frying planet proved to be so bent that it “disappeared” from the Intergovernmental Panel on Climate Change’s armoury of argument in 2007. It was bent because the historical data it used to predict the future dated from only the 1850s, when the world was emerging from the Little Ice Age. Little wonder that temperatures showed an upward trend.

In the Sixties I used to discuss climate change with my undergraduates at Durham University. I would point to the plethora of published scientific evidence that showed the cyclical nature of change – and how, for instance, the latest of a string of ice ages had affected the climate, sea levels and tree lines around the world. Thank goodness the latest crop of glaciers and ice sheets began to wane in earnest about 12,000 years ago; this gave Britain a window of opportunity to lead the industrial revolution.

The Romans grew grapes in York and during the worldwide medieval warm period – when civilizations blossomed across the world – Nordic settlers farmed lowland Greenland (hence its name) and then got wiped out by the Little Ice Age that lasted roughly from the 16th century until about 1850.

There is no escaping the fact that the concentration of carbon dioxide in the atmosphere has been rising for 150 years – and very uniformly since the 1950s. Yet the temperature has not increased in step with CO2. Not only have there been long periods of little change in temperature, but also the year-to-year oscillations are totally unrelated to CO2 change. What is more, the trend lines of glacial shortening and rise in sea level have shown no marked change since the big increase in the use of fossil fuels since 1950.

How can this be explained unless there are other factors at work overriding the greenhouse effect of CO2? There are, of course, many to be found in the peer-reviewed literature: solar cycles, cosmic rays, cloud control and those little rascals, such as El Niño and La Niña, all of which are played down or even ignored by the global-warming brigade.

Let’s turn to Al Gore’s doom-laden Oscar-winning documentary An Inconvenient Truth. First, what is the point of scaring the families of the world with tales that polar bears are heading for extinction? Last year Mitchell Taylor, of the US National Biological Service, stated that “of the 13 populations of polar bears in Canada, 11 are stable or increasing in number. They are not going extinct, or even appear to be affected at present.”

Why create alarm about a potential increase in the spread of malaria thanks to rising temperatures when this mosquito-borne disease was a major killer of people in Britain and northern Russia throughout the Little Ice Age?

Despite the $50 billion spent on greenwashing propaganda, the sceptics and their inconvenient questions are beginning to make their presence felt.

A recent survey of Klaus-Martin Schulte, of Kings College Hospital, of all papers on the subject of climate change that were published between 2004 and February of 2007 found that only 7 per cent explicitly endorsed a “so-called consensus” position that man-made carbon dioxide is causing catastrophic global warming. What is more, James Lovelock, the author and green guru, has changed his mind: he recently stated that neither Earth nor the human race is doomed.

Yes, melting sea ice around Greenland has recently opened up the fabled North West passage. And, yes, the years 2006 and 2007 have seen massive flooding in Europe. However, a quick dip into the records of the Royal Society – which ranked alongside Dr Lovelock as arch doomsters, before his change of mind – shows that dramatic fluctuations happened long before the infernal combustion engine began spewing out carbon dioxide.

The year 1816 went down in history as the “year without a summer”, thanks to the eruption of Mount Tambora in Indonesia that veiled much of the world with dust, screening out the Sun. Yet in 1817, while still in the grip of the Little Ice Age, the Royal Society was so worried that 2,000 square leagues of sea ice around Greenland had disappeared within two years, and massive flooding was taking place in Germany, that its president wrote to the Admiralty advising of the necessity of an expedition to find out what was the source of this new heat.

Perhaps, when similar things are happening 190 years later, the Royal Society should accept that anthropogenic carbon dioxide is unlikely to be the main – or only – driver of “global warming”.
