Andres Peña Castro and his team didn’t set out to track sea ice. Their original plan was to quantify the interactions between ocean, earth and atmosphere to be able to…

A population of bowhead whales living in the western Arctic has long followed the same migration patterns. But new research suggests that climate change and the subsequent melting of sea…

Norway is moving forward with plans to mine its continental shelf to procure minerals critical for renewable energy technologies. However, some scientists, members of civil society and even industry leaders…

In Tsiigehtchic, a village in Canada’s Northwest Territories where two rivers meet, a group of hunters returns to their community with pieces of caribou on toboggans dragged by their snowmobiles.…

New research finds that a record Arctic sea ice melt season in 2007 initiated a “regime shift” to thinner, more transient ice that may be “irreversible”; another study shows that atmospheric rivers from the south are warming the Arctic in winter.

This story was produced with the funding support of the Pulitzer Center. Janne Hirvasvuopio got his first Valentine’s Day card early this year. But the message that came through his…

Wild canids around the world are at risk, though some reintroductions are seeing good results. Conserving canids is not only good for ecosystem health, it can even potentially help curb climate change.

Melting sea ice may evoke images of polar bears stranded on shrinking floes or dramatically collapsing ice shelves. But according to a study published recently in the journal Science, ice…

As Arctic sea ice begins melting out fully in summer, the frequency of strong El Niños could increase by 35% by century's end, causing extreme weather events to increase, says recent modeling study.

Sea ice extent didn’t reach record lows this summer, but air temps over Greenland and ocean temps in some Arctic seas were extraordinarily high. Polar warming also likely continues influencing global extreme weather events, scientists say.

Narwhals are chaotic. At least, that’s what researchers thought until they developed a new math-based method to detect patterns in their seemingly irregular movements. Narwhals (Monodon monoceros) are known as…

The Gwich’in people of northern Alaska were disappointed when the Democratic-held U.S. Congress did not include a provision in the Inflation Reduction Act to protect the Arctic National Wildlife Refuge…

When Kristin Laidre began working on a long-term project to study polar bears in eastern Greenland, she didn’t expect to find a new subpopulation of the species — and she certainly…

Traditional and Indigenous peoples in the Arctic are joining with scientists to successfully rewild mining-degraded peatlands and other sites.

Arctic sea ice extent continued its trending decline in winter 2022, while the Antarctic saw a record low summer minimum extent. Both regions also saw extraordinarily high temperatures for this time of year.

Americans love their polar bears. The largest land carnivores in the world, these massive, powerful beasts are fierce, fearless and very much threatened. It’s the threatened aspect of their story…

Though September sea ice extent appeared to offer a short-term recovery this fall, “that’s not the full story,” says one Arctic scientist, with low ice concentration seen in 2021, and lack of multiyear ice setting a new record.

Naryan-Mar is a sea and river port town on the Arctic coast of Russia with a population of 22,000. It is a tundra ecosystem, with shallow peat soils. The local…

Researchers are seeking to pinpoint climate change “tipping points,” but defining what that means exactly, when it will come, and what makes it happen, is unimaginably difficult when faced with the chaotic complexities of a vast Earth biome.

Sea ice fell to its lowest extent on record for this time of year, while new studies find Arctic coastal ice may be receding 70-110% faster than thought, winter ice is failing to regrow fully, and last multi-year ice refuge is under assault.

Sea sponges don’t move. At least, that’s what a lot of people used to think about these aquatic invertebrates. But a new study has upended this assumption, and pushed and…

Polar phytoplankton, fish, seabirds and mammals are increasingly threatened by global warming, which is destabilizing Arctic ecosystems, even as southern species move northward — will the imbalanced biome collapse?

Simple mathematical models suggest overshooting Paris climate accord emission targets for a short time won’t immediately trigger some environmental tipping points, allowing time to act.

More than a decade after the Planetary Boundaries framework was first proposed by top scientists, we are no closer to changing our destructive trajectory — but 2021 gives us three opportunities to act.

New research finds that ice in both polar regions, and especially sea ice, is disappearing at a quickening rate, while in the Arctic the last stronghold of multiyear ice is under assault from warming.

The Greenland Ice Sheet is losing mass, and there may be no way to stop it, scientists have concluded. Even if large amounts of snowfall return to the ice sheet,…

Catching a caribou isn’t easy. In some locations, it involves flying around in helicopters, shooting the animal with a tranquilizer dart, making it safely to the ground, and placing a…

The solitude of the north is changing. George Angohiatok noticed this quite graphically a decade ago when, after returning to Iqaluktuuttiaq (or Cambridge Bay, as it was renamed by settlers), he observed…

The Arctic is setting records for low sea ice extent for this time of year, with the 2020 refreeze now 500,000+ square kilometers behind a record set in 2019 — a sign the region may be entering a new climate regime.

2020 didn’t eclipse all-time record-holder 2012, but it came pretty close; also, the Arctic’s growing heat is likely intensifying Asia’s extreme weather, while waters just beneath the ice are getting increasingly warm.
