Lima - Climate change has shrunk Peruvian glaciers by 40% in the past four decades and the melt-off has spawned nearly 1 000 new high-altitude lakes since 1980, Peru's government said on Wednesday.

Nearly 90% of Peruvian glaciers are smaller than 1-square-kilometer, putting them at greater risk of disappearing in coming years, Peru's water authority said in an update of its glacier inventory from the 1970s.

Peru's 2 679 glaciers, spread over 19 snow-capped mountain ranges, are the source of the vast majority of the country's drinking water.

Climate change is expected to diminish fresh water supplies in fast-growing Peru, though glacial melt-off could boost availability in some watersheds in the short-term.

In 1970, at least 20 000 Peruvians were killed after an earthquake sent a glacier sliding into the highland town of Yungay.

Peru's water authority said that 996 lakes have emerged in the Andes since 1980, when it last conducted a count, bringing the new total to 8 355.

Peru is home to 70% of the world's tropical glaciers, which are especially sensitive to warming temperatures.

Peru will host the United Nations conference on global climate change in Lima in late November and December.
