Arctic’s strongest sea ice breaks up for first time on record
The oldest and thickest sea ice in the Arctic has started to break up, opening waters north of Greenland that are normally frozen, even in summer. This phenomenon – which has never been recorded before – has occurred twice this year due to warm winds and a climate-change driven heatwave in the northern hemisphere. One meteorologist described the loss of ice as “scary”. Others said it could force scientists to revise their theories about which part of the Arctic will withstand warming the longest.

NASA has discovered Arctic lakes bubbling with methane—and that's very bad news
Lakes across Alaska and Siberia have started to bubble with methane, and the release of this highly potent greenhouse gas has scientists worried. Last month NASA released footage showing the bubbling Arctic lakes, which are the result of a little known phenomenon called “abrupt thawing.” It occurs when the permafrost—ground that has been frozen for potentially thousands of years—thaws faster than expected.

Arctic ice cap destabilizes at ‘unprecedented’ speed

Changes in snow coverage threatens biodiversity of Arctic nature
Many of the plants inhabiting northern mountains depend on the snow cover lingering until late spring or summer. Snow provides shelter for plants from winter-time extreme events but at the same time it shortens the length of growing season, which prevents the establishment of more southern plants. This is why the reduced snow cover may be an even larger threat to the Arctic plants than rising temperatures.

The Abandoned Graveyards on a Thawing Arctic Island
HERSCHEL ISLAND, ALSO KNOWN AS Qikiqtaryuk, is fragile and losing ground. The whalers are long gone, and the Inuvialuit who once called it home now only pass through every once in a while, as a seasonal place to camp, or as a stopover while they’re out hunting. This 45-square-mile island in the Beaufort Sea, north of the Arctic Circle, is largely abandoned, and threatened by erosion and rapidly vanishing permafrost.

KLM’s Arctic AR-10
In 1958 KLM began flying the transpolar route between Europe and Tokyo. Because of the dangerous route the flights took each plane carried an Arctic survival kit. This included: sleeping bags, tents, a raft, a shovel, snow shoes, a camp stove, cold weather clothing, a hatchet and a 7.62x51mm chambered ArmaLite AR-10.

The Arctic is in even worse shape than you realize
Over the past three decades of global warming, the oldest and thickest ice in the Arctic has declined by a stunning 95 percent, according the National Oceanic and Atmospheric Administration’s annual Arctic Report Card. The finding suggests that the sea at the top of the world has already morphed into a new and very different state, with major implications not only for creatures such as walruses...

Arctic reindeer numbers crash by half
The population of wild reindeer, or caribou, in the Arctic has crashed by more than half in the last two decades. A new report on the impact of climate change in the Arctic revealed that numbers fell from almost 5 million to around 2.1 million animals. The report was released at the American Geophysical Research Union meeting.

Don't be deceived: these fluffy bunnies enjoy devouring meat
Snowshoe hares eat meat, and they don't seem all that picky about what kind of animal it comes from. A natural history paper published recently in the journal Northwestern Naturalist documents hares in Yukon's boreal forest scavenging on grouse, loon, other hares and even lynx.

Climate change forces Arctic animals to shift feeding habits: study
Seals and whales in the Arctic are shifting their feeding patterns as climate change alters their habitats, and the way they do so may determine whether they survive, a new study has found. Researchers harnessed datasets spanning two decades to examine how two species of Arctic wildlife -- beluga whales, also known as white whales, and ringed seals -- are adapting to their changing habitat.

As ice fields melt in Norway, archaeologists are uncovering ancient weapons, tools and clothing, and racing to preserve the material record before it is destroyed. | All Desing İdeas
Since the singing sweltering summer of 2006, just about 3,000 archeological antiques have showed up from the softening ice in Oppland, Northern Norway. Among them, an Iron Age tunic, a 1,500-year-old bolt and a 3,400-year-old shoe.

Air temperatures in the Arctic are driving system change
A new paper shows that air temperature is the “smoking gun” behind climate change in the Arctic, according to John Walsh, chief scientist for the UAF International Arctic Research Center. Several University of Alaska Fairbanks researchers are co-authors on the paper, which says that “increasing air temperatures and precipitation are drivers of major changes in various components of the Arctic system.”

Melting permafrost in Arctic will have $70tn climate impact – study
The release of methane and carbon dioxide from thawing permafrost will accelerate global warming and add up to $70tn (£54tn) to the world’s climate bill, according to the most advanced study yet of the economic consequences of a melting Arctic. If countries fail to improve on their Paris agreement commitments, this feedback mechanism, combined with a loss of heat-deflecting white ice, will cause a near 5% amplification of global warming and its associated costs, says the paper, which was published on Tuesday in Nature Communications.

Canadian Arctic fossils are oldest known fungus on Earth
Tiny fossils found in mudrock in the barren wilderness of the Canadian Arctic are the remains of the oldest known fungus on Earth, scientists say. The minuscule organisms were discovered in shallow water shale, a kind of fine-grained sedimentary rock, in a region south of Victoria island on the edge of the Arctic Ocean. Tests on the shale, which accumulated over millions of years in a river or lake, revealed that it formed between 900m and 1bn years ago in what is now the Northwest Territories.
