Arctic permafrost is thawing fast. That affects us all. As the frozen ground warms much faster than expected, it’s reshaping the landscape—and releasing carbon gases that fuel global warming.

Data from two Arctic sites suggest some surface layers are no longer freezing. If that continues, greenhouse gases from permafrost could accelerate climate change. Ground collapses at Duvanny Yar ...

The Arctic permafrost is 1,000 years old. As it thaws, scientists worry what it might unleash In one troubling case, dozens of people were sickened − and thousands of reindeer were killed − ...

Permafrost thaw poses multiple risks to local Arctic communities, their livelihoods, infrastructure and environment. A transdisciplinary study led by Umeå University and others has identified key ...

Lightning strikes in the Arctic have surged in recent years, raising alarms among scientists about their role in wildfires, ...

The Arctic permafrost thaw is hazardous to the livelihood, safety, health, food security, and the infrastructure of communities living in Arctic regions, an international group of scientists have ...

Permafrost, the thick layer of perennially frozen ground that covers much of the Arctic, slows down the migration of Arctic rivers, according to a new Caltech study. River migration is a common ...

Environment Permafrost thaw beneath Arctic lakes poses surprise pollution threat. Deep sediments under Arctic lakes could release large amounts of carbon dioxide and methane, adding to the threat ...

Tuktoyaktuk itself now stands face to face with the Arctic Ocean’s increasingly angry Beaufort Sea, and rests atop 1,300 feet to 1,600 feet of thawing permafrost threatening to sink it.

A new study in Proceedings of the National Academy of Sciences highlights how the overlapping effects of sea level rise, permafrost thaw subsidence and coastal erosion could result in unprecedented ...

The vast frozen terrain of Arctic permafrost thawed several times in North America within the past 1 million years when the world's climate was not much warmer than today, researchers from the United ...

TUKTOYAKTUK, Canada — On the shore of Lake Tiktalik in Canada’s Western Arctic, the thawing permafrost had set off two huge landslides into the water, leaving yawning craters on the tundra.
