Sierra Nevada snowpack lowest in 500 years

With several ski resorts closing early last winter in California’s Sierra Nevada Mountains due to lack of snow, many people suspected the snowpack for the year was on the low side. This suspicion has been confirmed: Snow levels for the winter of 2014–2015 registered as the lowest in the last 500 years.

Shrinking snowpack projected in western U.S. as rain-snow boundary climbs higher

Gauging the impacts of climate change on future precipitation is challenging, especially in the western U.S., a region with highly variable temperatures, precipitation patterns and terrain. But understanding such impacts in the West — and, in particular, how much precipitation will fall as snow versus rain in the future — is important given the region’s dependence on wintertime snowfall as a freshwater resource. Now, a new study forecasts a broad shift from snow to rain for much of the West — a projection that will require attention from land and water resource managers planning for the future.

Endangered snow: how climate change threatens West Coast water supplies

If you turn the tap on in Seattle, the water flowing from the faucet likely originated as a clump of snow. In winter, snowflakes fall in the Cascades, accumulating in thick snowpack. The snowpack stores water in winter and slowly releases it in spring and summer as temperatures warm and snow melts. As snowmelt flows down the mountains, some of it is diverted and collected in reservoirs — destined to arrive in the homes of more than 1 million people.
