The mounds are believed to be caused by the build up of methane gas in pockets of thawing permafrost under the surface  Dissecting them like surgical abscesses to release the gas is seen as one solution to avoid future eruptions.

Permafrost thaw surrounding the massive Red Dog Mine is releasing higher natural levels of dissolved minerals and other particles into streams, Teck Resources Ltd. says

The size of salmon returning to rivers in Alaska has declined dramatically over the past 60 years because they are spending fewer years at sea, according to a new study led by researchers at the University of California, Santa Cruz, and the University of Alaska Fairbanks.

The Interdepartmental Working Group approved a list of priority measures to eliminate environmental damage in the town of Usolie-Sibirskoye, Irkutsk Region. This was reported by the press service of Deputy Prime Minister Victoria Abramchenko.

Radiation, chemical and biological forces tackle two million tonnes of toxic chemical waste with huge mercury stockpile and oil poisons.

“People assume that we’re entering this new Arctic, when in reality we have faced adversity for thousands of years. We’ve always been able to adapt and be resilient.

Towering crags and peaks of the Canadian Rocky Mountains have been getting steadily greener over the past century, according to a new study.

Jan Egil Bakkeby had to flee for his life when he suddenly heard it start to crack in the cabin. Soon after, he witnessed the entire building being washed up on water.

Melting permafrost, land erosion, and heavy rains are causing these villages to flood and sink

Soil organic carbon (SOC) stored in permafrost across the high-latitude/altitude Northern Hemisphere represents an important potential carbon source under future warming. Here, we provide a comprehensive investigation on the spatiotemporal dynamics of SOC over the high-altitude Tibetan Plateau (TP), which has received less attention compared with the circum-Arctic region. The permafrost region covers ~42% of the entire TP and contains ~37.21 Pg perennially frozen SOC at the baseline period (2006–2015). With continuous warming, the active layer is projected to further deepen, resulting in ~1.86 ± 0.49 Pg and ~3.80 ± 0.76 Pg permafrost carbon thawing by 2100 under moderate and high representative concentration pathways (RCP4.5 and RCP8.5), respectively. This could largely offset the regional carbon sink and even potentially turn the region into a net carbon source. Our findings also highlight the importance of deep permafrost thawing that is generally ignored in current Earth system models.

Scientists found out that amid climate change in the summer, drifting ice goes further north, and the coastal area is freed from ice for a longer period.

With enough animals, 80% of all permafrost could be preserved through the end of this century, researchers believe.

Many communities in the Northwest Territories are worried about the impacts climate change is having on their cemeteries.

Rising sea levels will threaten three times more people in the next 30 years than previously thought, according to the latest scientific estimates. Among the hundreds of millions of people worldwide facing the threat are the 400 residents of Newtok, Alaska. Rising river and eroding land is pushing the entire community to relocate, despite emotional and logistical hurdles.

A growing number of Arctic underground cellars are being rendered unreliable as global warming and other modern factors force changes to an ancient way of life.

The Mulchatna herd was not at the peak numbers it once had decades ago. Over-hunting, migration changes and wolf predation could be leading causes of decline in herd.

For half a century, Taku had been the one known Alaskan glacier to withstand the effects of climate change – until now.

The islands were first noticed by a student engineer who had observed the unidentified land masses in satellite images

For decades, efforts have been underway to tame the effects of erosion on the Magdalen Islands, an archipelago in the Gulf of St. Lawrence. But the effects of climate change left these tiny islands vulnerable when it came to facing two powerful and unpredictable storms in less than a year.
