Peruvian glaciers have shrunk by 25% since 1987, causing water shortages in rural villages. But ancient technology could help manage this precious resource.
Climate change threatens the water supply of nations around the world. But it's difficult to measure whether a region has sufficient water to satisfy the people who live there. Could satellites help?
New research forecasts that climate change will make multiyear stretches with low snow levels more common across western North America – bad news for water managers, farmers, foresters and skiers.
