An iceberg melts in Kulusuk, Greenland near the Arctic Circle, Aug, 16, 2005. A new report finds permafrost in the Arctic is thawing faster than ever before.

Critical permafrost research in Russia disrupted by war in Ukraine


Most of the world’s permafrost lies in Russia. Critical research looks at how melting permafrost contributes to global warming. But sanctions against Russia this year have disrupted field work and threatened collaborations among scientists.

Arctic permafrost is starting to thaw. Here’s why we should all care.

Carbon released from warming soil will accelerate climate disruption, according to a long-term study


Scientists are concerned that carbon released from the Earth’s soil as a result of climate change will stimulate more warming. A yearslong study attempts to quantify the risk.

Melting polar ice poses a serious global risk


The fast retreat of glaciers and polar ice is sobering, if not terrifying, in what it implies for the future of life here on Earth.

A bold plan to slow the melt of Arctic permafrost could help reverse global warming


In a tiny corner of the Siberian Arctic, Russian scientists are working to forestall global climate catastrophe by restoring the Ice Age ecosystem.

Thawing permafrost could have catastrophic consequences, scientists warn


As global temperatures increase, thawing permafrost starts to release large amounts of carbon dioxide and methane, which, in turn, raises global temperatures. This feedback loop could have dire consequences — and new research suggests we are getting close to making this loop irreversible.

Eight nations share the territory of the Arctic, which is experiencing the fastest changes of any part of the earth as global temperatures rise. The United States will emphasize addressing the causes and impacts of climate change in the region when it tak

As new leader of the Arctic Council, the US will focus on the region’s Big Thaw


Climate change is hitting the Arctic harder than anywhere else. And when it takes over leadership of the eight-nation Arctic Council later this month, the US will shift the organization’s priority from economic development to fighting — and adapting to — climate change.
