In the last few days of 2018, as the Arctic archipelago of Svalbard, Norway, lay cloaked in the long darkness of polar night, a shrimp trawler called the Northguider ran aground off the coast of one of the islands.

The fear that action to combat climate change has been too slow has led some scientists to test unconventional methods to stem the loss of Arctic sea ice.

Open water and rain, rather than ice and snow, are becoming typical of the region, a new study has found.

The fast-warming Arctic has started to transition from a predominantly frozen state into an entirely different climate, according to a comprehensive new study of Arctic conditions.

A 160-foot-deep crater has opened up in the Arctic permafrost. It is the result of built up methane gas released during the frost's thaw, scientists say.

The Planet Earth-observation company has just released new imagery of the broken Milne Ice Shelf in the Arctic. Located on the northern margin of Canada's Ellesmere Island, the ice platform split on 30/31 July to form a free-floating bloc some 80 sq km (30 sq miles) in area.

A study published earlier this year showed that peatlands in Canada are drying up and that fires there will become more common in the future.

Scientists say we have time to save polar bears if we act now to reduce greenhouse gas emissions.

Scientists at Stanford University have discovered a surprising shift in the Arctic Ocean. Exploding blooms of phytoplankton, the tiny algae at the base of a food web topped by whales and polar bears, have drastically altered the Arctic's ability to transform atmospheric carbon into living matter. Over the past decade, the surge has replaced sea ice loss as the biggest driver of changes in uptake of carbon dioxide by phytoplankton.

For the second year running, vital ecosystems are in flames. Several major fires in the Amazon have been spotted ahead of the rainforest’s typical fire season, and it seems likely that 2020 will see worse blazes than the ones which triggered international outcry last year.

The cold waters of the planet’s north are highly susceptible to carbon absorption and under a ‘business as usual’ climate change scenario the impacts to marine ecosystems and food chains could be dire...

Alarming heat scorched Siberia on Saturday as the small town of Verkhoyansk (67.5°N latitude) reached 100.4 degrees Fahrenheit, 32 degrees above the normal high temperature. If verified, this is likely the hottest temperature ever recorded in Siberia and also the hottest temperature ever recorded north of the Arctic Circle, which begins at 66.5°N.

Moss balls seem to roll around glaciers in a coordinated way, and researchers can't explain why the whole group moves at about the same speed and in the same direction.

Antarctica and Greenland lost thousands of gigatons of ice in the last 16 years, according to results

An “unprecedented” hole in the ozone layer which developed to become the largest ever seen over the Arctic has closed just weeks after opening, scientists observing the phenomenon have said. The gap in the vital layer, which protects the Earth from harmful radiation from the sun, set a new record for ozone depletion in the northern hemisphere when it formed earlier this month.

The loss of summer sea ice in the Arctic is now very likely before 2050, new research shows, even if the carbon emissions driving the climate crisis are cut rapidly. The result has alarmed scientists but they said slashing greenhouse gases remained vital as this would determine whether Arctic summer ice vanished permanently or could recover over time. If emissions remain very high, there is a risk the Arctic could be ice-free even in the dark, cold winter months, a possibility described as “catastrophic”.

The newfound bacteria might shed light on how chlamydia came to infect host organisms, like us.

Abrupt thawing of permafrost will double previous estimates of potential carbon emissions from permafrost thaw in the Arctic, and is already rapidly changing the landscape and ecology of the circumpolar north, a new CU Boulder-led study finds. 

Inuit sled dogs have changed little since people migrated with them to the North American Arctic across the Bering Strait from Siberia, according to researchers who have examined DNA from the dogs from that time span. The legacy of these Inuit dogs survives today in Arctic sled dogs, making them one of the last remaining descendant populations of indigenous, pre-European dog lineages in the Americas.
