Water Resources and Climate Change

A greenhouse warming is certain to have major impacts on both water availability and water quality. Temperature, pre­ cipitation patterns, evapotranspiration rates, the timing and magnitude of runoff, and the frequency and intensity of storms will be affected by increasing concentrations of carbon dioxide and other trace gases. A rise in sea levels associated with a global warming could threaten the fresh­ water supplies of coastal communities. And changes in temperature and rainfall levels will affect the demand for water, especially for irrigation.
