Further ice loss could have dramatic consequences, particularly in India, whose rivers were fed by Himalayan glaciers, and the US west coast, which gets water from glaciers in the Rocky Mountains and Sierra Nevada. The most severe loss had till now been recorded at Norway's Breidalblikkbrea glacier, which shrank 3.1m. On average, glaciers shrank by 1.5m. ''The figures are part of what appears to be an accelerating trend with no apparent end in sight,'' said Wilfried Haeberli, director of the World Glacier Monitoring Service, which conducted the study. Professor Haeberli said between 1980 and 1999 glaciers lost an average of 0.3m of ice a year. But since 2000 the average loss has increased to about 0.5m. UNEP's director Achim Steiner urged governments to agree stricter targets for emissions reductions.
