Scientists investigate a particular kind of fish that has evolved to survive in the severe arctic climate. However, on a field trip in 2018, they discovered an unusual phenomenon: several of the fish had terrible skin tumors.
Life in the Arctic is harsh. Arctic temperatures are punishing, making life difficult for many animals to survive. Yet lots of insects, including mosquitoes, manage to thrive in the frozen region. So why don't they freeze themselves?
Whales are huge, but they live in an even larger environment—the world's oceans. Researchers use a range of tools to study their whereabouts, including satellite tracking, aerial surveys, sightings and deploying individual hydrophones to listen for their calls.
Rising temperatures are melting the Arctic sea-ice on which polar bears hunt, limiting their access to food. A recent study has found a remote population of polar bears that have adapted to hunt on chunks of glacier ice.
As we know, the Arctic tundra won't be around much longer. Climate change is causing the sea levels to rise, and the ice to melt, which is also, in turn, wiping out the plant and animal species that live there. And unfortunately things aren't much different in Siberia.
Home to polar bears, the midnight sun and the northern lights, a Norwegian archipelago perched high in the Arctic is trying to find a way to profit from its pristine wilderness without ruining it.
These are strange times for the Indigenous Nenets reindeer herders of northern Siberia. In their lands on the shores of the Arctic Ocean, bare tundra is thawing, bushes are sprouting, and willows that a generation ago struggled to reach knee height now grow 3 meters tall, hiding the reindeer. Su ...
At first, it was a simple question: what exactly did oil pollution do to gray seals off the coast of Norway?

The ice shelf was cracking up. Surveys showed warm ocean water eroding its underbelly. Satellite imagery revealed long, parallel fissures in the frozen expanse, like scratches from some clawed monster. One fracture grew so big, so fast, scientists took to calling it “the dagger.”
The highest temperature ever recorded in the Arctic, 38C (100F), has been officially confirmed, sounding "alarm bells" over Earth's changing climate.
While a reduction in frozen ocean surface is one of the most widely recognised impacts of Arctic warming, it has also long been anticipated that a warmer Arctic will be a wetter one too, with more intense cycling of water between land, atmosphere and ocean.
The warship HMS Terror lies at the bottom of the Arctic Ocean in the Northwest passage, lost in 1848 after two grueling years stuck in the Arctic ice. Rescue missions launched to recover the ship in 1851 suffered the same fate, crushed under the year-round ice that encased Northern Canada and th ...

The annual migration of birds from the Arctic to the Gulf of Mannar Marine Biosphere Reserve, has begun with an enormous flock seen swarming the Manoli Islands inside the park last weekend.
Sweating, headaches, fatigue, dehydration – the ways heat exhaustion affects the human body are well documented. As temperatures inch up year by year we need to change the way we live, creating cooler places that provide refuge from heat.
One way that scientists monitor climate change is through the measure of sea ice extent. Sea ice extent is the area of ice that covers the Arctic Ocean at a given time. Sea ice plays an important role in reflecting sunlight back into space, regulating ocean and air temperature, circulating ocean ...

Warming of the Arctic caused by climate change has increased the number of polar vortex outbreaks, when frigid air from the far north bathes other parts of the Northern Hemisphere in killer cold, ...
In June, the Central Arctic Ocean Fisheries Agreement entered into force, bringing to fruition a diplomatic effort that began more than a decade ago.
Like many people, I will remember this summer in shades of gray and red. As snapshots of a dull orange sun circulated social media, "zombie fires" rose from the Russian permafrost, entire towns were wiped off the map and Southern Europe became a scene of the apocalypse.Satellites tracked enormou ...
Climate change is driving periods of unusually high temperature across large swaths of the planet. These heat waves are especially detrimental in the Arctic, where they can push surface temperatures in regions of significant permafrost past the melting point of ice lenses.
As the North Pole, the Arctic Ocean, and the surrounding Arctic land warm rapidly, scientists are racing to understand the warming's effects on Arctic ecosystems. With shrinking sea ice, more light reaches the surface of the Arctic Ocean. Some have predicted that this will lead to more plankton, ...
Natural silence -- the kind when you hear nothing but the sound of nature around you -- is becoming increasingly scarce. The rumblings of man-made noise can be heard even in the remote corners of national parks and deep in the Arctic Ocean.

Tropical waters are known for their bright sunlight above and their richly colorful biodiversity below. These two things aren’t unrelated; for the many tropical species that exhibit biofluorescence — that is, the ability to absorb light energy and reemit it as different colored light — the sunli ...

Rising global temperatures are causing frozen Arctic soil— permafrost—in the northern hemisphere to thaw and release CO2 that has been stored within it for thousands of years. The amount of carbon stored in permafrost is estimated to be four times greater than the combined amount of CO2 emitted ...
It's clear that rising greenhouse gas emissions are the main driver of global warming. But on a regional level, several other factors are at play. That's especially true in the Arctic—a massive oceanic region around the North Pole which is warming two to three times faster than the rest of the p ...
Researchers from SINTEF, the Norwegian Polar Institute and the University Centre in Svalbard have collected samples from Arctic crustaceans close to the settlement of Ny-Ålesund on the west coast of Spitsbergen. During the spring and summer, they discovered a number of drugs in a variety of diff ...

This remote part of the world faces unprecedented environmental assaults, as climate change and industrial chemicals threaten a way of life for Inuit and other Indigenous and northern communities that rely heavily on seafo ...
Climate change is having a widespread effect on lakes across the Northern Hemisphere, a new study has found. The study, published in the journal Geophysical Research Letters, examined 122 lakes from 1939 to 2016 in North America, Europe and Asia, and found that ice-free years have become more th ...
In the far north, the swelling Arctic Ocean inundated vast swaths of coastal tundra and steppe ecosystems. Though the ocean water was only a few degrees above freezing, it started to thaw the permafrost beneath it, exposing billions of tons of organic matter to microbial breakdown.
The Norwegian fishing village of Bugøynes, 310 miles north of the Arctic Circle and a frigid, dark place for much of the year, was on the edge of ruin.
New study suggests waters will become more turbulent as Arctic loses summertime ice.Eddies are often seen as the weather of the ocean. Like large-scale circulations in the atmosphere, eddies swirl through the ocean as slow-moving sea cyclones, sweeping up nutrients and heat, and transporting the ...
Under the sea ice, the Arctic Ocean is one of the quietest places on Earth. But it can be very noisy when the ice is forming and breaking up or during storms and when glaciers are calving.
The world is changing in dramatic ways, especially in the High Arctic. Climate change has meant that spring arrives earlier, but winters have become far more treacherous for Arctic animals that overwinter there, with more rain and ice.
Language is everything. Those who argue for oil drilling in the Arctic national wildlife refuge, a place of stunning wild beauty in far north-east Alaska, seldom call it what it is – a refuge.
Arctic sea ice has been in steep decline over the past two decades. A study of tundra shrubs published today in the journal PNAS shows that as sea ice disappears, the Arctic is becoming both greener and browner.
At just over 14 million square kilometres, the Arctic Ocean is the smallest and shallowest of the world’s oceans. It is also the coldest. An expansive raft of sea ice floats near its centre, expanding in the long, cold, dark winter, and contracting in the summer, as the Sun climbs higher in the sky.
