Global Warming Causing River Levels to Drop
Scientists at the National Center for Atmospheric Research (NCAR) in Boulder,CO have found that reduced water levels in many rivers around the globe is a direct result of climate change. This has the potential of disrupting food and water supplies in the future.
The results of this research are to be published May 15 in the American Meteorological Society's Journal of Climate. The research was supported by the National Science Foundation (NSF), NCAR's sponsor.
"The distribution of the world's fresh water, already an important topic," says Cliff Jacobs of NSF's Division of Atmospheric Sciences, "will occupy front and center stage for years to come in developing adaptation strategies to a changing climate."
"Reduced runoff is increasing the pressure on freshwater resources in much of the world, especially with more demand for water as population increases," says NCAR scientist Aiguo Dai, the lead author of the journal paper. "Freshwater being a vital resource, the downward trends are a great concern."
"As climate change inevitably continues in coming decades, we are likely to see greater impacts on many rivers and the water resources that society has come to rely on," says NCAR scientist Kevin Trenberth, a co-author of the paper, as reported by Science Daily.
