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

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........

Perhaps worst of all, the melting threatens to disrupt water supplies over much of Asia. Many of the continent's greatest rivers - including the Yangtze, the Indus, the Ganges, the Brahmaputra, the Mekong and the Yellow River - rise on the plateau.

In China alone, 300 million people depend on water from the glaciers for their survival. Yet the plateau is drying up, threatening to escalate an already dire situation across the country. Already 400 cities are short of water; in 100 of them - including Beijing - the shortages are becoming critical.

Even hopes that the melting glaciers might provide a temporary respite, by increasing the amount of water flowing off the plateau - have been dashed. For most of the water is evaporating before it reaches the people that need it - again because of the rising temperatures brought by global warning.
