With a warming climate and changing weather patterns, it might be time to update the federal reservoir-level rules that dictate how much water can be kept in some western U.S. reservoirs during winter.
People keep buying electric vehicles, and Nevada continues to build infrastructure to support the shift away from internal-combustion transportation. The shift reduces green-house gas emission.
A project to restore a damaged meadow in the Sierra Nevada shows the possibilities for improving an important mountain ecosystem. It can also store precious groundwater as climate change shrinks mountain snowpack, a vital source of fresh water in the American West.
Warming Sierra Nevada temperatures mean young trees of cold-adapted species are growing at elevations hundreds of feet higher than trees counted 80 years ago — taking entire habitats with them.
As wintertime temperatures warm in the Sierra Nevada, precipitation shifts from snow to rain. That means snowpack is shrinking — and changing the entire foundation for people’s water supply across the American West.
