"We can say there were times during the warmer periods of the last 10,000 years when glaciers have been comparable to what they are now," he told the BBC News website. "But it is not the past that worries us, it is the future. With the scenarios predicted, we will enter conditions which we have not seen in the past 10,000 years, and perhaps conditions which mankind has never experienced."

The steady rise in atmospheric levels of the greenhouse gases blamed for climate change shows no signs of abating, a UN agency has announced. The atmospheric concentration of carbon dioxide rose by about half a percent in 2005, the World Meteorological Organisation (WMO) said.

Satellite images show that, after decades of stability, a major glacier draining the Greenland ice sheet has dramatically increased its speed and retreated nearly five miles in recent years. These changes could contribute to rapid melting of the Greenland ice sheet and cause the global sea level to rise faster than expected, according to researchers studying the glacier.

"The rapid melting of Himalayan glaciers will first increase the volume of water in rivers, causing widespread flooding," said Jennifer Morgan, director of the WWF's Global Climate Change Programme.
