Global Water Cycle & Water Resources

All Topics >> This Topic's: Publications :: Meetings :: Ongoing Studies

The global water cycle plays a key role in the chemical, physical, and biological processes that sustain ecosystems and influence Earth's climate and associated global change. Clouds, water vapor, and precipitation alter heating and cooling of Earth's surface and atmosphere, which in turn, affect global circulation and precipitation patterns. Hydrologic data from atmospheric, surface, and subsurface stations are critical to the development of more accurate predictions of water distribution and availability, cloud formation, and precipitation in a changing climate. The National Research Council carries out a variety of studies, workshops, and meetings and publishes numerous reports on science-policy issues related to climate change and global water cycle and water resources.
