In severe warming scenarios, the study found that more than 75% of Earth’s near-surface permafrost will be gone by the end of the century.

A year after Russia invaded Ukraine, a walrus discovery is caught up in geopolitics
For decades, stretching back to the Cold War, Russian and American scientists have been close partners on Pacific walrus research.
Amid Alaska’s permafrost areas, more soil is staying thawed year-round, UAF scientists find
Warmer winters and thicker layers of insulating snow are spurring creation of more taliks, sections of ground that doesn’t freeze even in winter.
Alaska permafrost thaw is clue in mystery of Arctic methane explosions
Arctic methane explosions — and the scientists who love to study them — are the focus of the newest episode of the public television program Nova.
LISTEN: Alaska research shows melting permafrost is affecting infrastructure faster than expected
New research on how climate change affects things built on or in permafrost shows this type of infrastructure will deteriorate faster than expected.
As Arctic warming accelerates, permafrost thaw hits Red Dog mine with $20 million bill
Red Dog’s problems show how climate change poses a challenge to the economy of Arctic Alaska, which is warming at triple the rate of the global average.
New map shows the potential future of permafrost on the North Slope
“We hope that this tool will be useful for engineers who [are] doing some projects in this area, for government thinking about what they should expect, and also for any people who live in Alaska,” Vladimir Romanovsky said.
Scientists warn Arctic “refrigerator” is failing, with global consequences
Still melting – and melting fast. That’s the basic take-away from the federal government’s annual Arctic Report Card. It finds that Arctic ocean temperatures are increasing and sea ice is declining at the fastest rate in at least 1500 years.
Models show permafrost melting faster than thought
UAF researchers reported findings from Arctic permafrost modeling that indicates thawing may dramatically affect ecosystems and infrastructure.
