Climate, climatic change, and water supply



The earth's climate is changing, and associated predictions of future floods and droughts reverberate throughout the news media. Coupled with forecasts of climatic change one can often find associated predictions of social unrest, wars, and famines, but these possible derivative issues have not been addressed. We considered only the simpler problems of water shortages, which may or may not be severe enough to be classified as droughts and which may or may not have resulted from climatic change. We also assessed the probable effects of climatic variability and climatic change upon the nation's water supply needs, policy, and design.
