ORNL News highlights permafrost study

A new study shows a few degrees of warming can trigger abrupt thaws of vast frozen lands, releasing huge stores of greenhouse gases and collapsing landscapes.

Dr. Colleen Iversen is an ecosystem ecologist who uses a variety of field and laboratory techniques to understand and predict how ecosystems are shaped by environmental change.

Scientists measured how nitrogen availability to plants varies spatially and temporally in the Arctic tundra.

You think it's cold in East Tennessee? Try getting close to the North Pole, where the wind chills in early autumn routinely whip down to -25°C (-13°F).

Misha Krassovski is one of the 60 some scientific personnel who embarked on the first leg of the largest polar expedition of all time, called the Multidisciplinary Drifting Observatory for the Study of Arctic Climate, or MOSAiC.

Emission data shows that the thawing of permafrost is turning these areas from carbon sinks into carbon emitters.

As the frozen ground warms much faster than expected, it's reshaping the landscape--and releasing carbon gasses that fuel global warming.
