World's Major Rivers 'drying up'

摘要

Researchers from the US-based National Center for Atmospheric Research (NCAR) analysed data combined with computer models to assess flow in 925 rivers - nearly three quarters of the world's running water supply - between 1948 and 2004. The study reveals that some of the developing world's largest rivers are drying up because of climate change, threatening water supplies in some of the most populous places on Earth, say scientists. The report will be published in the 15 May 2009 issue of Journal of Climate published by the American Meteorological Society.
