Second only to the melting of the Arctic ice and those "drowning" polar bears, there is no scare with which the global warmists, led by Al Gore, more like to chill our blood than the fast-vanishing glaciers of the Himalayas, which help to provide water for a sixth of mankind. Recently one newspaper published large pictures to illustrate the alarming retreat in the past 40 years of the Rongbuk glacier below Everest. Indian meteorologists, it was reported, were warning that, thanks to global warming, all the Himalayan glaciers could have disappeared by 2035.

Yet two days earlier a report by the UN Environment Program had claimed that the cause of the melting glaciers was not global warming but the local warming effect of a vast "atmospheric brown cloud" hanging over that region, made up of soot particles from Asia's dramatically increased burning of fossil fuels and deforestation.

Furthermore a British study published two years ago by the American Meteorological Society found that glaciers are only shrinking in the eastern Himalayas. Further west, in the Hindu Kush and the Karakoram, glaciers are "thickening and expanding".

Meanwhile, all last week, ITV News was running a series of wearisomely familiar scare stories on the disappearing Arctic ice and those "doomed" polar bears - without telling its viewers that satellite images now show ice cover above its 30-year average, or that polar bear numbers are at record level. But then "polar bears not drowning after all - as snow falls over large parts of Britain" doesn't really make a story.
