Within a set of glaciers and mountains near Juneau, there’s seismic activity almost every day in the summer. They’re called ice quakes. They’re not as widely understood as earthquakes, but researchers are monitoring them closely.
The U.S. Forest Service said it plans to approve Coeur Alaska’s plan to expand facilities at the Kensington Gold Mine, extending the life of the mine by another 10 years.
A contractor tore down six structures in the past few weeks, part of a process to remove erosion-threatened places that began almost a decade ago.
A researcher's quest to understand a mysterious mass extinction leads to cud-chewing culprits.
Global climate warming is most severe in the Arctic. One consequence is a widespread reduction in permafrost. Continuous, stable permafrost can act as a physical glue that helps anchor unstable slopes. Increasingly, scientists are reporting collapse of rock slopes in the High Arctic.
“We’re dropping in elevation because we live on ice cubes,” says a scientist trying to map permafrost.
Micah Hahn, an assistant professor of environmental health at the University of Alaska Anchorage, says while it might seem obvious that wildfire smoke causes health impacts, there had actually never been a nuanced, scientific look at those impacts. The biggest impact was for asthma-related emergency department visits. This was really across the board and across age groups and in geographic areas.
Fearing that runoff from the December rains might have carried contamination to Henderson Farm in Haines, the American Bald Eagle Foundation has told its renters they won't be able to farm their plots this year.
Upgrades are needed on the tarmac
Climate warming has accelerated the permafrost degradation, which influences the processes of water supply, runoff and discharge in the Source Area of the Yellow River (SAYR) in the northeast of Qinghai-Tibet Plateau.
A federal regulator has lifted a stop-work order on tree cutting and grass mowing along the route of the Trans Mountain pipeline expansion project.
For 30 years now, climate change has been driving the sands further into the Nogai steppe, gradually transforming the traditional homeland of a the people that once dominated much of southern Russia from green and pleasant pasture to barren desert.
Work will stop until 21 August after the discovery of an Anna’s hummingbird nest during construction of TransMountain pipeline
Tons of mud and rock have plunged onto a beach just yards away from homes at Rhodfa Mor on the Gwynedd coast. Another landslide happened in the same area around a month ago, which allegedly caused a tree to crash through a bedroom window.
‘Something has to be done right now ... don’t wait for the time when we’re going to be moved off and be refugees in our own country’
Experts raise concerns about residents who refuse to evacuate as ‘huge explosion’ reported at La Soufriere volcano. The volcano, which last erupted in 1979, began spewing copious amounts of ash on Friday.
The volcanic eruption on the Reykjanes peninsula is creating lava flows from three locations in a roughly kilometre-long area. All three locations are part of the same magma dyke and the flow of lava from them into Geldingadalir and Meradalir valleys has now merged into one lava field.
As sea levels rise along the Atlantic coast, saltwater is intruding inland, killing trees and turning coastal forests into marshes. Should scientists try to slow the process, or work with it?
Midway along the 92-mile road that winds through Denali National Park, at a spot with an elevation of 3,500 feet and spectacular views of the Alaska Range and the braided rivers that flow out of it, an unstable wall of rock, ice, soil and clay rises precariously. The slope into which the road was cut eight decades ago is already collapsing gradually — and there are fears that it could collapse much more suddenly in the future.
The landfill in Rankin Inlet, Nunavut, is overfull, but the hamlet can’t open a new landfill until it can pay to decommission the old one, says hamlet Mayor Harry Towtongie. A new environmental report says bad dumps are a problem in all of Canada's Inuit regions.
