The acceleration of change in the Arctic due to global warming is transforming the landscape on a year-to-year basis, often ...

A study has found that as climate change causes the Arctic permafrost to melt, pathogens may awaken and damage crops. The ...

Increasingly thawing permafrost soils not only pose a global threat due to the CO 2 and methane gas stored in them, but also have far-reaching implications for the approximately three million ...

The team of researchers explored caves in Canada to look for clues left in speleothemsmineral deposits accumulated over thousands of years—that might help answer when in the past did Canadian ...

Climate change played a key role in the 'catastrophic' 2023 floods in the Himalayan state of Sikkim in India, a new study ...

The scientists found that the thawing permafrost posed an increased risk of exposure to infectious diseases and release of contaminants, and interruptions of supply routes. The study has been ...

"The most climate-stressed regions all contained permafrost, which is vulnerable to thaw as temperatures rise," researcher Sue Natali said.

A seemingly minor trickle of groundwater beneath Alaska’s tundra is quietly releasing vast amounts of carbon into the ocean.

The study is also the first to isolate freshwater — which could be made up of rainwater, snow melt, thawed shallow ground ice, and potentially some permafrost thaw — from the total groundwater ...
