Asian Glaciers Turn to Sand

{excerpt . . .}

Ice-capped roof of world turns to desert
Scientists warn of ecological catastrophe across Asia as glaciers melt and continent's great rivers dry up
By Geoffrey Lean

Global warming is rapidly melting the ice-bound roof of the world, and turning it into desert, leading scientists have revealed.

The Chinese Academy of Sciences - the country's top scientific body - has announced that the glaciers of the Tibetan plateau are vanishing so fast that they will be reduced by 50 per cent every decade. Each year enough water permanently melts from them to fill the entire Yellow River.

They added that the vast environmental changes brought about by the process will increase droughts and sandstorms over the rest of the country, and devastate many of the world's greatest rivers, in what experts warn will be an "ecological catastrophe".

The plateau, says the academy, has a staggering 46,298 glaciers, covering almost 60,000 square miles. At an average height of 13,000 feet above sea level, they make up the largest area of ice outside the polar regions, nearly a sixth of the world's total.

The glaciers have been receding over the past four decades, as the world has gradually warmed up, but the process has now accelerated alarmingly.

Sandstorms, blowing in from the degraded land, are already plaguing the country. So far this year, 13 of them have hit northern China, including Beijing. Three weeks ago one storm swept across an eighth of the vast country and even reached Korea and Japan. On the way, it dumped a mind-boggling 336,000 tons of dust on the capital, causing dangerous air pollution. . . .
