If you feel the ice cracking beneath you before a fall, prepare yourself for the shock of cold water. The shock of the water causes immediate changes in breathing and heart rate, so it is not to be underestimated.

The study highlights how rapid Arctic warming increases the frequency of extreme weather events, particularly concurrent heatwaves across Europe and eastern Asia.

In April 2024, Churchill's waste management facility-an old military building known as L5-burned to the ground. Spontaneous combustion in the gaseous garbage pile was the likely cause. The warehouse had been capable of storing up to three years' worth of the town's garbage at a time. Overnight, the town's 900 or so residents were left with nothing.

The first victim was located approximately one meter below the surface and showed signs of life after being freed. The second burial was beyond the reach of standard probe rods, and the victim was eventually found 13 to 16 feet down.

I don't know who invented this crazy challenge, but the idea is to put someone in a carved-out ice bowl and see if they can get out. Check it out! The bowl is shaped like the inside of a sphere, so the higher up the sides you go, the steeper it gets. If you think an icy sidewalk is slippery, try going uphill on an icy sidewalk. What do you do when faced with a problem like this? You build a physics model, of course.

There's a glorious smugness that can only be experienced by exercising outdoors in winter conditions. The fresh air, the endorphins, the reduced risk of heart disease they're all nice bonuses, but nothing beats that knowing nod from another rain-drenched runner, or the horrified faces of nearby dog walkers as you stride confidently into the sea for a winter dip.

To capture the biological impact of this extreme environment, I used a comprehensive suite of sensors and biomarker analyses. I wore a wireless electroencephalograph (EEG) system to monitor brain activity, sleep stages and neural signatures of stress and adaptation; the Oura Ring to continuously track sleep patterns, heart-rate variability and circadian-rhythm shifts; and the glucose monitor to follow metabolic responses in real time.

He had flown in from Mar-a-Lago and, he told me, was there to observe. The next day, he watched as Åsa Rennermalm, a Rutgers University professor who studies polar regions, sat onstage with European foreign ministers and spoke out against cuts to U.S. science funding. "A leading US Arctic scientist is on stage absolutely ripping her country to the delight of the audience," Dans wrote on X. "Embarassing." He punctuated his post with an American-flag emoji.

Wind chill is a measure of how quickly bodies lose heat when you combine low temperatures with high winds. And wind chill conditions can be dangerous. "The stronger the winds [and] the colder it is, the more likely you are to develop frostbite in a short amount of time or hypothermia," says Jessica Lee of the National Weather Service's Weather Prediction Center.

On paper, many of the world's most famous weapons looked like reliable successes. In practice, desert sand, jungle humidity, and arctic cold often had other ideas. Systems that performed well in testing or early combat sometimes broke down once environmental stress became unavoidable. Here, 24/7 Wall St. is taking a closer look at how the environment, not enemy fire, can quietly expose limits that designers never fully anticipated.

In the pristine High Arctic sits the Kitsissut island cluster, also known as the Carey Islands, nestled between northwest Greenland and northeast Canada. The surrounding seas are perilous, and traveling there is difficult even with modern boats. But new archaeological evidence suggests ancient humans managed to sail to the islands, too. Early settlers lived on the islands between 4,500 and 2,700 years ago.

Packing for a truly freezing destination takes more than tossing a few sweaters into your bag-something I quickly learned in the Arctic Circle during polar night, when "daytime" is pitch-black and the temperatures regularly plunge well below zero. Growing up in New York winters, spending the last few snow seasons in the Rockies, and now logging weeks above the Arctic Circle has taught me one key lesson: staying warm in subzero temps is all about smart layers -not necessarily bulky expedition gear.

Polar bears are the poster children of climate changeand for good reason. These giant bears hunt, mate and spend their days hanging out on Arctic sea ice, which is rapidly disappearing as the climate warms. But some polar bears, it seems, are far more resilient than we realized: new research suggests that in one region, the bears are adapting to the declining sea ice.

Decades of successful scientific collaboration could be at risk if Europe-US political relations continue to fray over trade and defense issues. For more than 30 years, Arctic nations have worked together across the physical, biological and social sciences to understand one of the world's fastest changing regions. Since the late 1970s, the Arctic has lost around 33,000 square miles of sea ice each year roughly the same area as Czechia.

Cody Cirillo and Matthew Tufts set out to do something that sounds simple until you picture the map, the season, and the wind. In the dead of winter, they bike-packed and skied their way around Iceland on a 1,000-mile, 35-day, human-powered loop. Their new film, A Hundred Words for Wind , released December 18, tracks the whole push, from ice-choked roads and sideways rain to those rare, hard-won windows when the mountains finally opened long enough to climb and ski.

Alaska is a hot spot for grizzly bears, easily home to the most of any of the 50 states. There are an estimated 30,000 across the entire state, representing over 98 percent of the United States population. The Alaska Department of Fish and Game manages the population, ensuring that the population remains healthy and grizzly bear viewing opportunities stay abundant.

The record-breaking arctic blast that hit Florida earlier this month may have sent humans scurrying for winter coats, but it sent wildlife scurrying, swimming and slithering for their lives. Some of those animals were native, some were invasive. Some survived. Thousands of others did not. The benchmark for cold snaps in Florida is the 2010 freeze, which killed manatees, crocodiles, iguanas, thousands of snook and goliath grouper, and caused 50% to 90% of invasive pythons to die in some areas.

Recently, Anchorage, Alaska's largest city with nearly 400,000 residents, has just recorded its snowiest January on record. Tucked in between the mighty Cook Inlet and pushed right up against the Chugach Mountains, Anchorage sits in prime location for some serious snow totals. Moisture from pacific storms builds up over the inlet, and thanks to orographic lift caused by the mountains, forces that moisture to drop over Anchorage. Thanks to Alaska's northernly location, that moisture often falls in the form of snow.

During a rare break in the weather, the NYT says helicopters airlifted the researchers and their equipment 19 miles to their planned outpost site on top of the glacier. The two helicopters involved flew a dozen total loads of cargo from the icebreaker ship to the camp site, while glacial scientists and engineers erected a small tent city, complete with bathrooms, generators, and a mess hall.
