Iceland’s volcano eruptions may last decades, researchers find

Iceland’s ongoing volcanic eruptions may continue on and off for years to decades, threatening the country’s most densely populated region and vital infrastructure, researchers predict from local earthquake and geochemical data. The eruptions on the Reykjanes Peninsula have forced authorities to declare a state of emergency, with a series of eight eruptions having occurred since 2021. This […]

Researchers use AI to track global squirrel hot spots

Squirrels are arboreal acrobats that spread tree-generating seeds, mushrooms and fungi spores and serve as food for predators. As important as squirrels are to ecosystems, their exact habitat needs and ranges are not widely known. In a recent study published in Scientific Reports, a team of University of Alaska Fairbanks researchers used novel artificial intelligence and […]

Western Agricultural Communities Need Water Conservation Strategies to Adapt to Future Shortages 

Reno, Nev. (June 12, 2024) – The Western U.S. is heavily reliant on mountain snowpacks and their gradual melt for water storage and supply, and climate change is expected to upend the reliability of this natural process. Many agricultural communities in this part of the country are examining ways to adapt to a future with […]

Global temperature is likely to exceed 1.5°C above pre-industrial level temporarily in next 5 years

There is an 80 percent likelihood that the annual average global temperature will temporarily exceed 1.5°C above pre-industrial levels for at least one of the next five years, according to a new report from the World Meteorological Organization (WMO). This is a stark warning that we are getting ever closer to the goals set in […]

Researchers identify fastest rate of natural carbon dioxide rise over the last 50,000 years

CORVALLIS, Ore. May 13, 2024 – Today’s rate of atmospheric carbon dioxide increase is 10 times faster than at any other point in the past 50,000 years, researchers have found through a detailed chemical analysis of ancient Antarctic ice. The findings, just published in the Proceedings of the National Academy of Sciences, provide important new […]

Peak Water: Do We Have Enough Groundwater to Meet Future Need?

RICHLAND, Wash. May 10, 2024—A new study finds that, by mid-century, nearly half the global population could live in areas where groundwater will become so costly as to raise regional food prices and significantly alter the geography of trade and crop production. Nine percent of the world’s water basins appear to have already reached such […]

Lake Tsunamis Pose Significant Threat Under Warming Climate

The names might not be familiar—Cowee Creek, Brabazon Range, Upper Pederson Lagoon—but they mark the sites of recent lake tsunamis, a phenomenon that is increasingly common in Alaska, British Columbia and other regions with mountain glaciers. Triggered by landslides into small bodies of water, most of these tsunamis have occurred in remote locations so far, […]

Webb Captures Top of Iconic Horsehead Nebula in Unprecedented Detail

The mid-infrared instrument (MIRI), managed through launch by NASA-JPL, helped reveal for the first time the small-scale structures of the nebula’s edge. NASA’s James Webb Space Telescope has captured the sharpest infrared images to date of a zoomed-in portion of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show […]

COVID-19 booster immunity lasts much longer than primary series alone, York University-led study shows

TORONTO,  April 22, 2024 – Thinking about getting a spring-time booster shot? A new study coming out of York University’s Centre for Disease Modelling in the Faculty of Science shows that immunity after a COVID-19 booster lasts much longer than the primary series alone. These findings are among other, sometimes “unintuitive,” revelations of how factors like age, sex […]

Fires pose growing worldwide threat to wildland-urban interface areas

Fires that blaze through the wildland-urban interface (WUI) are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. The research team, led by scientists at the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR), used satellite observations and […]
