The new study, published in the June issue of PNAS Nexus, examines a 40-meter long ice core from Mont Blanc’s Dôme du Goûter. Using radiocarbon dating techniques, the research team found that the glacier provides an intact record of aerosols and climate dating back at least 12,000 years. Aerosols are small droplets and particles in the air such as desert dust, sea salts, sulfur from volcanic eruptions, soot from forest fires, as well as pollutants and other emissions from human activities.
Earth is hotter than it has been in 125,000 years, scientists say, and Las Vegas continues to break temperature records. Planting and preserving the city’s street trees is one method that brings many benefits, from the cool air of their shade to their ability to store carbon. Now, a new study takes a deeper look at just how much trees can offer Sin City, as well as the water tradeoffs inherent in growing trees in a desert.
Ancient bristlecone pines have been collecting data for us for millennia. Anne Heggli’s research aims to provide a nearly microscopic look at how the climate in the Great Basin is changing, from hour to hour and season to season. With scientific monitoring equipment positioned from the floor of the Great Basin’s Spring Valley up to the peak of Mount Washington, her project examines temperature fluctuations, atmospheric information, and snowpack insights across the region’s ecosystems.
To help protect miners and assist mine managers in reducing hazardous exposures, DRI scientists Xiaoliang Wang, Judy Chow, and John Watson are conducting free trainings to raise awareness about health risks and effective protection methods. Data from the Mine Safety and Health Administration (MSHA) show that as much as 27% of miners are overexposed to air contaminants.
DRI scientist Kristin VanderMolen, Ph.D., has been awarded the 2025 Rising Researcher Award in recognition of her outstanding early-career accomplishments and potential for advancing scientific knowledge in the field of applied anthropology.
Researchers from DRI and UNR teamed up for this new study, published October in Environmental Science & Technology. Using sociodemographic data from the U.S. Census Bureau and public health and air pollution information from the EPA between 2011 and 2019, the study identified higher estimated cancer risk tied to air toxics in urban communities, those with lower incomes, and those with higher proportions of racial minorities.
Patrick Hurbain, Ph.D., is an environmental epidemiologist working with Judy Chow, John Watson, and Xiaoliang Wang in the Environmental Analysis Facility. In the following interview, Hurbain discusses how his childhood in Stead influenced his career trajectory, his new study published in Environmental Science & Technology, and his hopes for bringing the chili cook-off back to DRI.
Twenty-six years since it was first awarded, the Peter B. Wagner Award for Women in Atmospheric Science remains the only award in the United States for female graduate students in the atmospheric sciences. Thanks to the generosity of Sue Wagner, the exceptional work of women graduate students in the atmospheric sciences will continue to be recognized and honored in perpetuity.
DRI is pleased to announce that the 26th annual Peter B. Wagner Memorial Award for Women in Atmospheric Sciences has been awarded to Catherine (Casey) Ivanovich of Columbia University. The Peter B. Wagner Memorial Award for Women in Atmospheric Sciences is an annual competition recognizing the published works of women pursuing a master’s or Ph.D. in the atmospheric sciences.
In an effort to better understand urban heat islands and their impacts on our region, a group of organizations, led by the Nevada State Climate Office, is seeking volunteers to track heat on August 10 for the Reno-Sparks Heat Mapping Project. Volunteers will set out in pairs to drive or navigate a predetermined route, equipped with a GPS-equipped temperature and humidity sensor that can be affixed to a volunteer’s car. The original project date was postponed due to unusually cool weather.
