Avalanche risks are rising—researchers say governance must rise with them

Phys.org: Earth science - Sun, 03/15/2026 - 17:30

The findings of a new paper show governance and preparedness rather than hazard magnitude determine whether avalanches become mass-casualty events. With large ice-rock avalanches growing in frequency as steep slopes in the Himalaya become unstable due to rapid glacier retreat, extreme precipitation and permafrost degradation, scientists believe saving lives, protecting infrastructure and reducing long-term economic losse s in some of the world's most hazard-exposed regions could be achieved through several practical steps.

Models warn Thwaites Glacier could rival entire Antarctic ice loss by 2067

The future of one of Antarctica's most iconic glaciers could be far more dramatic than scientists previously thought. Using satellite calibrated ice sheet models, a team of researchers from the University of Edinburgh found that the Thwaites Glacier in West Antarctica could be shedding 180–200 gigatonnes of ice per year by 2067—a rate roughly comparable to the entire Antarctic ice sheet's current mass loss. That would represent a stunning acceleration in ice loss from a single glacier and underlines urgent concerns about future contributions to sea level rise.

Alaska's glacial lakes are expanding, increasing the risk of destructive outburst floods

Phys.org: Earth science - Sat, 03/14/2026 - 18:30

Every summer, people living near the Mendenhall River in Juneau, Alaska, keep a close eye on the water level. When the river level begins to rise rapidly, it's a sign that Suicide Basin, a small glacier-dammed lake 5 miles up the mountains, has broken through the glacier again and a glacial lake outburst flood is underway.

Eaton fire sent a pollution wave across Los Angeles, study shows

Phys.org: Earth science - Sat, 03/14/2026 - 18:00

The 2025 Eaton fire's smoke did more than darken the sky: It generated a carbon monoxide and particulate matter surge that far exceeded Los Angeles County's average daily human-caused emissions, according to a new study led by researchers at the USC Dornsife College of Letters, Arts and Sciences. The findings are published in the journal ACS ES&T Air.
