The world was warmer than it is now in the early Middle Ages, long before industrial activity increased CO2 output

But take, just for example, the famous picture of polar bears on a melting ice-floe, supposedly doomed victims of global warming.

The USA’s ex-Vice President, the propagandist Al Gore, got audiences going ‘Aaah!’ by saying the bears had ‘nowhere else to go’. Really? The picture was taken in August, when the Alaskan ice always melts. The polar bears were fine. Think about it.

They can swim and they weren’t far from land. Recent studies show that most polar bear populations are rising.

The world was warmer than it is now in the early Middle Ages, long before industrial activity increased CO2 output, a fact that the warming fanatics have worked very hard to obscure.

Oh, and the most important greenhouse gas by far is not CO2 but water vapour, which is not influenced by human activity at all.

Meanwhile, an English court of law (despite buying the CO2 argument) has identified nine significant errors of fact in Gore’s Oscar-winning alarmist film An Inconvenient Truth, ludicrously being inflicted on children in British schools.

Among these: sea levels are not going to rise by 20ft any time soon; there’s no evidence that atolls in the Pacific have been evacuated because of rising waters; the Gulf Stream is not going to shut down; the drying-up of Lake Chad, the shrinking of snow on Mount Kilimanjaro and Hurricane Katrina were none of them caused by global warming; the only polar bears that have drowned were four that died in a storm.

Booker also reminds us that even if all the measures demanded by the warming zealots were put into action, according to their own calculations this would only delay the effects they fear by six years.

In my experience, people who employ alarmism, and who turn with rage on their critics, do so because they lack confidence in their case. Watch their behaviour at the coming Copenhagen climate conference, a festival of panic and exaggerated woe.

This particular frenzy, if not checked, could end by bankrupting the West and leaving us sitting in the cold and the dark whistling for a wind to power our dead computers – while China and India surge on to growth and prosperity because they have had the sense to ignore the whole stupid thing.
