BELLAMY ENCOURAGES SCIENTISTS' SCEPTICISM ON CLIMATE CHANGE

Internationally renowned environmental campaigner Professor David Bellamy has joined the New Zealand group of scientists trying to refute what they believe are unfounded claims about man-made global warming. Dr Bellamy, who joins scientists such as former MetService chief meteorologist Dr Augie Auer in the New Zealand Climate Science Coalition, was introduced to the group through a member in England. The coalition has set down "seven pillars of climate wisdom" that include:

* Historically, conditions in many parts of the world have been warmer and cooler than they are now.

* A major driver of climate change is variability in solar effects, such as sunspot cycles, and not increased carbon dioxide.

* Global temperatures have not increased and a projection of solar cycles suggest cooling could set in and continue to about 2030.

* Stories of impending climate disaster are based almost entirely on global climate models.

Dr Bellamy said: "I look forward to working with the New Zealanders to create an international coalition to serve as a united voice for the many scientists around the world who believe climate science is not settled, that the world is not on the brink of a man-made global warming catastrophe and that we have much more to learn about this planet of ours that has been through and survived many natural upheavals and climatic cycles."

In 2004, Dr Bellamy described man-made global warming as "poppycock" then asserted last year that a large percentage of the world's glaciers were advancing, not retreating, but later admitted the figures were wrong.

NIWA climate scientist Brett Mullan, who is also a member of the Royal Society's New Zealand Climate Committee, said the coalition's refusal to believe in man-made global warming was a "frustration". "I am disappointed. We point them to the evidence and they just don't seem to wish to accept it." He said climate modelling had proven effective, such as in projecting temperature increases after the eruption of Mt Pinatubo in the Philippines in 1991. Solar activity, monitored over the past 30 years, did not account for the climate changes being experienced now. Temperatures varied from year to year, with the last peak in 1998, but overall temperatures were still much higher now than in the 1950s or 60s. [Pick a date and get any answer you wish] Dr Mullan said the world's top climate scientists had formed a consensus through the Intergovernmental Panel on Climate Change. "We are seeing warming and it's caused by human activities."

THE CONSENSUS VIEW IS FREQUENTLY VERY WRONG INDEED

One of the most misguided ideas in any debate is the idea that the consensus view is usually, if not always, right. All too frequently the accepted wisdom has been completely and comprehensively wrong. We may react with disbelief that anyone believed, or indeed still believes, that ships would sail over the edge of earth, and possibly be gobbled up by monsters, because the earth was flat. But historically this has been an accepted wisdom. And we may be bemused, even a trifle alarmed, that Galileo was threatened with the torture because he supported Copernicus's revolutionary (no pun intended) theory that the earth goes round the sun rather than vice versa. But Copernicus's maverick theory challenged a consensus that was politically dangerous to challenge.

Economics, albeit more prosaically, has also been subject to fads, whims and consensus views to which history has not been kind. Twenty-five years ago Britain was at an economic crossroads. The credibility of the British economy was collapsing as inflation and unemployment soared, manufacturing output slumped and the national debt spiralled upwards. Margaret Thatcher and her Chancellor, Sir Geoffrey Howe, concluded that drastic action was required. Taxes were raised by £4bn (then a huge sum) in the 1981 Budget in order to provide scope for lower interest rates and tackle public sector borrowing. There was, unsurprisingly, substantial political opposition.

But, of more interest, 364 economists signed a letter to The Times stating that there was "no basis in economic theory or supporting evidence" for Sir Geoffrey's policy and that it threatened Britain's "social and political stability". An alternative course of action must be pursued, these savants insisted. Almost the entire academic economic establishment stood against the Government with a mere handful of brave "mavericks" dissenting from the consensus view. But, as we now know, the letter's signatories were wrong because they believed in the then ubiquitous, but faulty, Keynesian consensus of the time.

Moreover, not only did the economics establishment regard Sir Geoffrey's Budget as fundamentally flawed, they also took the same view of the mavericks' judgments. This is instructive. Many in academia seem to believe that "peer-reviewed" research guarantees impartial, sound and independent assessment. It does not. Mavericks can be marked down and dismissed by their consensus-minded peers. Dissension is rarely popular.

The story of the 364 economists should be a warning to all who give the impression that the consensus view is an impregnable fortress of truth. Yet only recently Sir David King, the Government's Chief Scientist, was again reassuring us that at a meeting in Monterrey, Mexico, there had been a "scientific consensus" about climate change. Man-made carbon emissions were the main drivers of global warming. But the meeting was organised by the British Government to discuss the climate change action plan agreed at Gleneagles last year and the main protagonists were G8 ministers, hardly independently minded free spirits.

By happy coincidence, as the G8 delegates were flying to and from Monterrey, liberally scattering carbon emissions into the ether, the Royal Society was publishing a paper by a team from the Danish National Space Center (DNSC) of the utmost scientific significance. Interestingly, the DNSC team leader, one Henrik Svensmark, has been impeded and persecuted by scientific and government establishments in recent years because his findings have been politically inconvenient. Politically inconvenient they are indeed.

Very briefly, the latest DNSC research shows how cosmic rays from exploding stars can encourage cloud formation in the earth's atmosphere. As the Sun's magnetic field, which shields the earth from cosmic rays, strengthened significantly during the 20th century the average influx of cosmic rays, and hence cloudiness, was reduced over this period. The resulting reduction in cloudiness, especially low-altitude clouds which have an overall cooling effect, could, therefore, be a highly significant factor in the last century's global warming.

I am no climate scientist. But it is clear this research seriously challenges the current pseudo-consensus that global warming is largely caused by manmade carbon emissions. All the current carbon hysteria is a mistake - and a potentially costly one at that.

I have to admit I have some reservations about the Royal Society. They have sorely misrepresented me in the press at least twice. And they have frequently been accused of being the Government's mouthpiece on the science of global warming. After all, 67pc of their funding, some 30 million pounds, comes from Government. They have also, apparently, been accused of denying funding to any climate scientist who does not share their alarmist views. But, in publishing this research, they have added to a debate that has major economic and business implications for this country. They should be applauded.

"Climate change" as a scapegoat

Australia is the dry continent -- with recurrent droughts. But opportunists are blaming the present dry spell on global warming. Writing with particular reference to his home State of Victoria, Andrew Bolt writes that this is just a convenient excuse for governmental failure to prepare for the inevitable drought conditions

The merchants of global warming panic are wrong. Again. No, this is not the worst drought ever recorded. No, it is not so unprecedented that it proves man-made global warming is real. In fact, this may not even be a drought at all. Rainfall figures show we may be simply going back to the just-as-dry weather of the not-so-distant past. And those who shriek that global warming is now frying us like never before are peddling green hype, rather than the cool science we need to keep ourselves well-watered.

I'm referring, of course, to religious zealots such as Deputy Premier John Thwaites, the (No) Water Minister, who declared: "So all the evidence points to a significant involvement of global warming in the present drought." I'm referring also to Professor Peter Cullen, a National Water Commission member and top government adviser, who gloated that, thanks to the drought, "flat earth sceptics who have been in denial about climate change are now realising that wishing it away didn't work and are now berating governments for not building more dams". And I mustn't forget The Age, this cult's Bible, which claimed: "The continuing drought has forced . . . belated recognition by sceptics that climate change is not a fiction disseminated by doomsayers."

Nonsense. Consult not their faith but my facts, and look at the graph on the right, showing Victoria's annual rainfall from 1900 to 2005, as measured by the Weather Bureau. What you see are decades of often dry years followed by decades of often wet ones. And now -- in this past decade of drought -- we've gone back to where we once were. As in dry. Here are the figures that tell that story.

From 1900 to 1945, Victoria's average annual rainfall was 603mm. Then came 50 years of plenty, with average falls of 671mm. But in the past decade our rainfall has dropped back to around the average of those pre-war years -- or 591mm. You might say this still means we're (a fraction) drier than before. But this past decade is not even close to being the driest on record. Our average rainfall now of 591mm is still way above the panting lows recorded from 1936 to 1945 -- an average of just 543mm. And no one back then wailed in the dust about global warming.

So what does all this suggest? Three things. First, as I warned here two years ago, Victoria's patterns of rainfall may have shifted. Second, this change in climate is not at all unusual or extreme, and so certainly not proof of global warming, let alone of the man-made kind. Third, we may not even be in a drought at all, but returning to drier conditions that are perhaps more usual. What may be unusual is not this dry, but the few wet decades before that filled our big new Thomson dam.

None of what I've said will surprise people with a long history of managing the land and its water. Hear it from farmer George Warne, general manager of the giant Murray Irrigation, who says: "It is an overreaction to say this (drought) is climate change. "My family has been farming (in Victoria) since 1888, and we have kept records on weather conditions. I am certain a huge component of the latest drought is cyclical." Or hear it from the boss of water company United Utilities, Graham Dooley, who, like me, does not deny climate change, but says: "About every 50 years we get a drought. This latest dry is part of the typical cycle."

So if this drought -- or dry spell -- is not unusual, you should ask some hard questions of a few powerful people who don't seem to be facing these facts. Here's one: Why didn't the Bracks Government prepare the state for a big dry that's actually a normal part of our ever-changing climate? Why didn't it build a new dam for growing Melbourne, say, and find new supplies for Ballarat and Bendigo, when we still had time on our side?

The Government still hides behind the excuse that this drought came out of nowhere -- a sudden catastrophe caused only by this spooky and unexpected phenomenon of global warming. But these rainfall figures show that the only thing spooky is the way the Government is using a seemingly natural change in the weather as proof of the rightness of its green faith that humans are ruining the world. But the figures show something more serious besides -- that blaming the drought on man-made global warming is actually just a miserable excuse for failure. Why didn't our leaders do more long ago to save our parched cities from a normal drought that any fool could have seen coming? Even a fool like me.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.

Global warming has taken the place of Communism as an absurdity that "liberals" will defend to the death regardless of the evidence showing its folly. Evidence never has mattered to real Leftists
