Findings of unexpected large numbers of fin and humpback whales in the previously ice infested waters of East Greenland now indicate a tipping point in the marine ecosystem from one regime to another that may be irreversible. Peer-Reviewed Publication

Norilsk Nickel has eliminated the consequences of the 2020 disaster. But Taimyr still has many environmental problems

As frigid wind whipped across the ship's bow, I held the railing with one hand and steadied my camera with the other. In front of me stretched the Bellingshausen Sea, off the coast of Western Antarctica. I was there — my second journey to the region around the southernmost continent — early this year on a five-week voyage as a photographic expert aboard the National Geographic Endurance.

Climate change is causing the Arctic Ocean’s sea ice to melt away. When the polar ocean loses its cover of sea ice, carbon dioxide uptake increases disrupting the food web in the water according to a study in the journal Science co-authored by researchers from the University of Gothenburg.

The Arctic coasts have been eroding at elevated rates in recent years.

A major new project will help benchmark biodiversity change in the Arctic Ocean and guide conservation efforts by identifying unique species and assessing their extinction risk.

Climate change is resulting in sea level rise as ice on land melts and oceans expand.

Icebergs bigger than city blocks loom through the mist as Kaleeraq Mathaeussen reels in halibut from the frigid waters one by one.

WASHINGTON — The White House on Friday released a 10-year Arctic strategy that emphasizes deterring increased Russian and Chinese activity in the region as global warming rapidly melts the polar ice caps, drastically transforming the environment.

A new scientific review article captures the unique and dynamic characteristics of coastal lagoon ecosystems in the Arctic Beringia Region, and discusses how climate change effects and human development could alter these habitats.

Marine mammals unlock the secrets of climate and the Arctic

Across the planet, ice is rapidly disappearing. From mountain tops, the poles, the seas, and the tundra. As the ice melts, it’s exposing new surfaces, new opportunities, and new threats — including valuable mineral deposits, archaeological relics, novel viruses, and more.

Across Antarctica, some parts of the base of the ice sheet are frozen, while others are thawed. Scientists show that if some currently frozen areas were also to thaw, it could increase ice loss from glaciers that are not currently major sea-level contributors.
