Climate change puts California’s snowpack under the weather

Skiing in July? It could happen this year, but California’s days of bountiful snow are numbered. The Sierra Nevada snowpack, which provides 60 percent of the state’s water via a vast network of dams and reservoirs, has already been diminished by human-induced climate change and if emissions levels aren’t reduced, the snowpack could largely disappear during droughts, a new study finds.

(Geo)science matters: Landslide research in California

Right now it’s incredibly important for scientists to hammer home why science is essential, important and needs to be practiced rigorously, transparently and without censorship. It’s clear that we can no longer limit ourselves to broader impact statements in our next grant applications. I thought I’d do my part by starting a new blog series and highlighting United States geoscientists and their work in action.

New study identifies next faults to fail along California-Nevada border

A handful of faults lining the border of California and Nevada may be near the point of rupture, according to a new study assessing earthquakes in the region as far back as 1,400 years ago. Scientists report that earthquakes in a fault network east of the Sierra Nevada Mountains are not random, but are likely triggered from stress bestowed by past earthquakes. This same type of stress has built up in six faults near Death Valley, California, and Reno, Nevada, according to the new research.
