Richard Seager and Park Williams discuss how water will be affected by warmer temperatures, and how their research increases understanding of these issues.

As the world warms due to climate change, shifts in global distribution of rainfall can be expected, impacting water resources across the planet.

Seager, a climate scientist at Lamont-Doherty Earth Observatory, discusses his research on drought in the North American Southwest.

A study co-authored by Michael Puma found food security risks for the entire globe hiding in the water use practices of major food producing nations.

The melting of glaciers will affect drinking water supplies, water needed to grow food and supply energy, as well as global sea levels.

As the Southwestern U.S. grows hotter, the risk of long-lasting megadroughts rises, passing 90% this century if greenhouse gas emissions continue at their current pace.

Scientists have identified 32 water basins where loss of snowpack as temperatures warm is putting the water supplies of large populations at risk.
