How the West can survive smaller snowpacks and bigger atmospheric rivers
Mountains are the foundation of water in the western United States, natural infrastructure that captures snowfall during the winter and releases snowmelt over the spring and summer. In California, the snowpack holds nearly as much water on average as all the reservoirs put together, effectively doubling the state’s surface storage. But, as the world warms, we may not be able to rely on this ecosystem service much longer. A new study projects that snowpack shrinkage will likely disrupt the West’s water system well before the end of the century.
