Only about 4 million people live in the Arctic, but despite its relatively small population, the region is hugely consequential.

Sinking terrain caused by the loss of ice and soil mass in permafrost is causing deeper thaw than previously thought and making vulnerable twice as much carbon as estimates that don’t account for this shifting ground.

The post Vulnerable carbon stores twice as high where permafrost subsidence is factored in, new research finds appeared first on GeoSpace.

Permafrost and wetlands in high latitudes could switch from carbon sink to carbon source by the end of the century, according to a recent study. Using a model of terrestrial ecosystems that showed how carbon is stored and released in soils at high latitudes, researchers revealed that climate change could cause these soils to release much more carbon than previously predicted.

The mission aims to track the potential impact of methane and carbon dioxide emissions on climate change.

These are the best preserved specimens of this extinct Arctic lion ever found.

The last time they squirmed was in the Pleistocene Age.

The accelerating melt is a global concern: Permafrost, which mostly lies in the northern reaches of the planet, is a vast carbon storehouse of frozen plants and animals that release greenhouse gases as they warm and decompose.

What lies inside the icy cavern seems more and more like a captive, rare animal, an Earth form that might soon be lost
