An examination of Rocky Mountain snow finds higher contamination levels of mercury and others metals in the northern part of the range, consistent with increased current and historical mining in the region. The study, published in the May issue of the journal Environmental Pollution, examined contamination levels for Mercury, Zinc, Cadmium and Antimony from nearly 50 sites in the Rocky Mountains.
Relying on water storage won’t be enough to make up for declines in future water availability under a changing climate, new study shows. Beatrice Gordon, lead author of the study and sociohydrologist and postdoctoral researcher at DRI, says the research is needed to inform water management at the local level, where most decisions are made.
DRI contributes to research that predicts a major decline in California’s snowpack by the end of the 21st century.
The snow-inducing technique called cloud-seeding has been around for more than 60 years. Although not a panacea for drought-stricken regions, cloud-seeding can increase seasonal precipitation by about 10%. In the Reno area alone, winter cloud-seeding efforts are estimated to add enough water to supply about 40,000 households for a year.
