The findings suggest vast rivers of glacial meltwater rushed into the sea, pooling over dense salty ocean water.

Thawing Arctic permafrost releases stored greenhouse gases, transforming the region from a carbon sink to a net source of ...

At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results provide the first direct geochemical evidence of the ...

Scientists have discovered that the Arctic's vast permafrost areas are now releasing more greenhouse gases than they absorb, ...

Among the most rapidly changing parts of our planet are the coldest landscapes near the top of the globe, just south of the ...

All people on Earth depend on the cryosphere. Snow, glaciers, ice sheets, sea ice, and permafrost are significant reservoirs ...

At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results from a Virginia Tech-led study provide the first ...
