New Study Finds Rocky Mountain Snow Contamination

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.

Blurring the Line Between Rain and Snow: The Limits of Meteorological Classification

A new study published in Nature Communications utilizes insights gleaned from DRI’s Mountain Rain or Snow project to evaluate why traditional weather forecasting struggles to identify the rain/snow transition line. The research was possible because thousands of community members across the U.S. contributed more than 40 thousand observations of the type of precipitation falling at their location.

DRI Invites Nevada Families to Science and Literacy Events for Pre-K Students

DRI’s STEM Education Program is holding free events focused on developing literacy through engaging science activities for Pre-K children 5 and younger throughout Nevada. Through hands-on experiments, story time, and interactive games, the events will bring ecology and electricity to life for the whole family. Each child will also receive free books to take home (while supplies last).

Weather Whiplash is Amplifying Wildfire Risk

While fires engulfed large swaths of southern California in early January, destroying more than 16,000 structures, taking at least 29 lives, and choking the air with smoke, a new study about weather whiplash was released. Co-authored by DRI’s Christine Albano, the research examined how a warming climate is creating an atmosphere more prone to extreme weather. Now, Albano and her co-authors have released a new report that applies the knowledge gained from January’s study to the recent fires, analyzing the broader climatic context that contributed to the unprecedented infernos.

New Study Traces Indigenous Population Shifts in North America Before Europeans

DRI’s Erick Robinson, Associate Research Professor of Climate and Archaeology, co-authored a new study that provides insight into North America’s Indigenous communities prior to European contact. The research found that although Indigenous populations varied regionally, the continent saw a population peak around 1150 A.D. before experiencing declines, likely stemming from drought, disease, emigration and warfare. A brief recovery around 1500 A.D. was followed by a sharp decrease upon the arrival of Europeans.

Floods, Droughts, Then Fires: Hydroclimate Whiplash is Speeding up Globally

DRI’s Christine Albano co-authored a new study that examines how a warming climate is creating an atmosphere more prone to extreme weather. This “hydroclimate whiplash” is evident in California’s recent weather, with winters filled with repeated atmospheric river storms driving the plant growth that the dry summers then parched, providing plentiful fuel for explosive wildfires.
