Why More Trees in the Sierra Mean Less Water for California

California water districts are eyeing a potential new source of water: trees. After a century of fire suppression, Sierra Nevada forests are more dense than ever before. And those pine trees are taking up a lot of water that might otherwise run off into California rivers.

Why Distant Dust Storms Matter to California Rainfall

Scientists are finding that dust storms in Asia and Africa influence how much snow falls in the Sierra Nevada. The research could help make weather forecasting more accurate and improve how California manages its water supply.

California’s Vanishing Glaciers: A Defining Moment

The Lyell and Maclure glaciers in Yosemite – like glaciers and ice sheets worldwide – are in rapid state of retreat. The Lyell and Maclure were presumed to be “true” glaciers – that is, thick slabs of ice dragged downhill under their own weight, scouring the land as they move – but scientists are discovering that the Maclure is deteriorating as it moves, and the Lyell is no longer moving at all.

A Summer Communing With California’s Glaciers

Earlier this year, geologists in Yosemite Park came to the sad conclusion that one of California's iconic glaciers, the Lyell, had ground to a halt, having lost too much mass to sustain its downward movement. Knowing that California's approximately 130 glaciers will not be around forever, Tim Palmer spent a summer on a personal quest to climb and photograph as many of these frozen giants as he could manage.

Airborne Lasers Yield Better Measure of California’s Water Supply

Snow runoff from the Sierra Nevada provides about a third of the state's water supply. Current estimates of how much water is in the mountains combine patchy measurements with a kind of sophisticated guesswork. But that may be about to change with new technology that's currently being tested.
