A giant sheet of ice measuring 260 sq km (100 sq miles) has broken off a glacier in Greenland, according to researchers at a US university.

The block of ice separated from the Petermann Glacier, on the north-west coast of Greenland.

It is the largest Arctic iceberg to calve since 1962, said Prof Andreas Muenchow of the University of Delaware.

ScienceDaily (Jan. 1, 2010) The most recent studies by researchers at ETH Zurich show that in the 1940s Swiss glaciers were melting at an even-faster pace than at present. This is despite the fact that the temperatures in the 20th century were lower than in this century. Researchers see the main reason for this as the lower level of aerosol pollution in the atmosphere.

Fears are growing for the future of water supplies in one of Latin America's fastest-growing urban areas - Bolivia's sprawling city of La Paz and its neighbour El Alto.

Scientists monitoring the glaciers high in the Andes mountains - a key source of water - say the ice is showing signs of shrinking faster than previously forecast.

Faced with a booming population and a combination of glacial retreat and reduced rainfall, the governor of the La Paz region is even contemplating moving people to other parts of Bolivia.
