ZEALOTRY OVER GLOBAL WARMING COULD DAMAGE OUR EARTH FAR MORE THAN CLIMATE CHANGE



Nigel Lawson has entered into the debate by writing a new book, "An Appeal To Reason: A Cool Look At Global Warming", which will be published next Thursday.

In the meantime, here is an extract from an article he has written in today's Daily Mail:

Over the past half-century, we have become used to planetary scares. In the late Sixties, we were told of a population explosion that would lead to global starvation. Then, a little later, we were warned the world was running out of natural resources. By the Seventies, when global temperatures began to dip, many eminent scientists warned us that we faced a new Ice Age.

But the latest scare, global warming, has engaged the political and opinion-forming classes to a greater extent than any of these.

The readiness to embrace this fashionable belief has led the present Labour Government, enthusiastically supported by the Conservatives and Liberal Democrats, to commit itself to a policy of drastically cutting back carbon dioxide emissions - at huge cost to the British economy and to the living standards not merely of this generation, but of our children's generation, too.

That is why I have written a book about the subject.

Now, I readily admit that I am not a scientist; but then neither are the vast majority of those who espouse the currently fashionable madness. Moreover, most of those scientists who speak with such certainty about global warming and climate change are not climate scientists, or Earth scientists of any kind, and thus have no special knowledge to contribute.

Those who have to take the key decisions aren't scientists either. They are politicians who, having listened cto the opinions of relevant scientists and having studied the evidence, must reach the best decisions they can - just as I did when I was Energy Secretary in Margaret Thatcher's first government in the early Eighties.

But science is only part of the story. Even if the climate scientists can tell us what is happening, and why they think it is happening, they cannot tell us what governments should be doing about it. For this, we also need an understanding of the economics: of what the economic consequences of any warming might be, and, if there is a problem, the best way of dealing with it.

First, then, what is happening? Given that nowadays pretty well every adverse development in the natural world is automatically attributed to global warming, perhaps the most surprising fact about it is that it is not, in fact, happening at all. The truth is that there has so far been no recorded global warming at all this century.

The world's temperature rose about half a degree centigrade during the last quarter of the 20th century; but even the Hadley Centre for Climate Prediction and Research - part of Britain's Met Office and a citadel of the current global warming orthodoxy - has now conceded that recorded temperature figures for the first seven years of the 21st century reveal there has been a standstill.

It is a very long article, which you should read in full, either online, or by buying the newspaaper.

After considerable reasoned argument, he concludes:

So the new religion of global warming, however convenient it may be to the politicians, is not as harmless as it may appear. Indeed, the more one examines it, the more it resembles a Da Vinci Code of environmentalism. It is a great story, and a phenomenal bestseller. It contains a grain of truth - and a mountain of nonsense.

And that nonsense could be very damaging indeed.

We appear to have entered a new age of unreason, which threatens to be as economically harmful as it is profoundly disquieting. It is from this, above all, that we really do need to save the planet.
