Arctic lakes are vanishing in surprise climate finding

The Arctic is no stranger to loss. As the region warms nearly four times faster than the rest of the world, glaciers collapse, wildlife suffers and habitats continue to disappear at a record pace.

Wildfire smoke may have amplified Arctic phytoplankton bloom

Smoke from a Siberian wildfire may have transported enough nitrogen to parts of the Arctic Ocean to amplify a phytoplankton bloom, according to new research from North Carolina State University and the International Research ...

Lower methane emissions when permafrost disappears

Thawing permafrost in the Arctic does not always have to lead to increased emissions of the greenhouse gas methane. When thawed soil dries up, emissions can decline instead. A new study at the University of Gothenburg demonstrates ...

Permafrost thaw could release bacteria and viruses

When considering the implications of thawing permafrost, our initial worries are likely to turn to the major issue of methane being released into the atmosphere and exacerbating global warming or issues for local communities ...

How much carbon will peatlands lose as permafrost thaws?

Just as your freezer keeps food from going bad, Arctic permafrost protects frozen organic material from decay. As the climate warms, however, previously frozen landscapes such as peatlands are beginning to thaw. But how much ...

Bacteria release climate-damaging carbon from thawing permafrost

A new study based on scientific sampling of a rusty carbon sink at a permafrost peatland at Sweden has revealed that iron minerals fail to trap organic carbon, a vast source of CO2 and methane not included in global warming ...
