ERICE, SICILY – Here at the World Federation of Scientists' annual meeting on energy seminars, the warm autumn sun shines on the golden-gray limestone of the medieval monasteries that are now temples of science, asking much the same questions about the origin and destination of the universe as the pious monks once asked.

One thing has become ever clearer in the five years since I first came here to deliver a lecture to 200 of the world's most eminent scientists on the apparently obscure topic of clouds and climate sensitivity: The profiteers of doom are themselves doomed. The climate is not responding as the bed-wetters had said it would.

There have been two plenary sessions devoted to the climate this year. By convention, the Erice meetings are subject to Chatham House rules, which prevent me from repeating what any particular participant said. However, I can certainly report that the increasing temperature of the debate between the true-believers in climate doom and the hard-headed skeptics is not matched by global mean temperature, which has not risen for 18 years and seven months, even though fully one-third of man's effect on the climate since 1750 has occurred in the same period.

In the Canadian army, trainees are taught what it is like to have to fight an opposing force. They call the imaginary enemy the "Fantasians." That seems to me to be the perfect word for the true-believers in climate cataclysm. They are increasingly removed from reality.

Gradually, the Fantasians who used to attend the annual seminars here on a noble mountain-top overlooking the azure Mediterranean have slunk away. They know the end of their dominance is near.

For, as was pointed out during the plenary sessions here, the rate of global warming since the U.N.'s climate panel made its first exaggerated predictions in 1990 has been little more than a third of what we were told it would be.

As always here in Erice, a quiet, learned bombshell was dropped – and dropped so subtly that most of the participants did not at first notice. I cannot give details of the form this bombshell took, for that would pre-empt a forthcoming publication in one of the leading learned journals of climate science.

But I can tell you what it means. The Fantasians' computer models have made a prodigious exaggeration of one particular variable in the equation that tells them how much global warming to expect. What this means is that there will in fact be considerably less manmade global warming over the coming century than even I had at first thought.

As recently as January this year, in a learned paper with three distinguished colleagues, I wrote in the Science Bulletin of the Chinese Academy of Sciences that there would not even be 1 Celsius degree of new manmade global warming this century.

The effect of the bombshell, delivered by one of the sharpest of the many sharp minds here, will halve that estimate. There cannot now be more than 0.5 Celsius, or about 1 Fahrenheit, of new manmade warming by 2100 compared with today.

For that bombshell, though the biggest of them all, was not the only one to be quietly dropped into the windowless, earthquake-proof, reinforced-concrete bunker that is the chief lecture-hall at the Ettore Majorana Centre for Scientific Culture. It was also revealed that the U.N.'s accident-prone climate panel has cut another key variable in the global-warming equation by a quarter, reducing the warming we may expect by as much as a third.

It was also explained that only two-thirds of the global warming predicted to occur in response to our altering the climate will occur within a century of our influence, and that in any event our influence does not all occur in the present but will increase slowly over the 21st century, again halving the warming predicted by the hapless U.N. climate panel.

Of course, the panel also predicts that there will be some further warming from our past sins of emission. But here's the thing: Even if the U.N. is right about that (which is unlikely after 223 months without any global warming), we can do nothing about it. Once we have returned to the atmosphere some of the CO2 that was once resident there in concentrations at least 15 times today's, there is very little that we can do to get it back out again. Nature will do that for us over time, but we cannot much accelerate the process.

The point is that, even in theory (through probably not in practice), the only warming we can now affect is the warming that has not yet occurred this century.

But what about the warming that will therefore occur in the next century? Scientifically speaking, there is no need to worry about it, because a rate of warming so slow that we shall only see half a degree of new manmade warming this century is not going to lead to catastrophe.

Economically speaking, it might be worth doing something to try to prevent some of this year's expected global warming, but the next century is too far away for us to need to take any steps now. The rational course would be to wait and see whether global warming accelerates: After all, the planet is scarcely warmer today than it was two decades ago, so we have plenty of extra time to see whether any action needs to be taken before throwing taxpayers' money away on boondoggles like wind farms that slice birds and bats to bits and swipe them out of the sky, or solar collectors that fry passing birds to a crisp.

Naturally, the pompous Fantasians who have a meal-ticket for life negotiating meaningless but cripplingly expensive climate deals at the interminable series of U.N. annual climate conferences do not know anything about this. They have no idea how very silly they are beginning to look. If they bothered to read WND, they would know the truth.
