Arctic rivers face big changes with warming climate, permafrost thaw and accelerating water cycle • Alaska Beacon


As the Arctic warms, its mighty rivers are changing in ways that could have vast consequences – not only for the Arctic region but for the world.

Rivers represent the land branch of the earth’s hydrological cycle. As rain and snow fall, rivers transport freshwater runoff along with dissolved organic and particulate materials, including carbon, to coastal areas. With the Arctic now warming nearly four times faster than the rest of the world, the region is seeing more precipitation and the permafrost is thawing, leading to stronger river flows.

We’re climate scientists who study how warming is influencing the water cycle and ecosystems. In a new study using historical data and sophisticated computer models of Earth’s climate and hydrology, we explored how climate change is altering Arctic rivers.

We found that thawing permafrost and intensifying storms will change how water moves into and through Arctic rivers. These changes will affect coastal regions, the Arctic Ocean and, potentially, the North Atlantic, as well as the climate.

Thawing permafrost: Big changes in Arctic soils

Permafrost thaw is one of the most consequential changes that the Arctic is experiencing as temperatures rise.

Permafrost is soil that has been frozen for at least two years and often for millennia. It covers approximately 8.8 million square miles (about 22.8 million square kilometers) in Earth’s Northern Hemisphere, but that area is shrinking as the permafrost thaws.

Historically, most water going into Arctic rivers flows atop frozen permafrost soils in spring. Scientists call this “overland runoff.”

However, our results suggest that as warming continues, an increasing fraction of annual river flow will come from under the surface, through thawed soils in the degrading permafrost. As the overall flow increases with more precipitation, as much as 30% more of it could be moving underground by the end of this century as subsurface pathways expand.

When water flows through soil, it picks up different chemicals and metals. As a result, water coming into rivers will likely have a different chemical character. For example, it may carry more nutrients and dissolved carbon that can affect coastal zones and the global climate. The fate of that mobilized carbon is an active area of study.

More carbon in river water could end up “outgassed” upon reaching placid coastal waters, increasing the amount of carbon dioxide released into the atmosphere, which further drives climate warming. The thaw is also revealing other nasty surprises, such as the emergence of long-frozen viruses.

More rain and snow, more runoff

The Arctic’s water cycle is also ramping up as temperatures rise, meaning more precipitation, evaporation, plant transpiration and river discharge. This is primarily due to a warmer atmosphere’s inherent ability to hold more moisture. It’s the same reason that bigger snowstorms are occurring as the climate warms.

Our study found that the bulk of the additional precipitation will occur across far northern parts of the Arctic basin. As sea ice disappears in a warming climate, computer models agree that a more open Arctic Ocean will feed more water to the atmosphere, where it will be transported to adjacent land areas to fall as precipitation.

More snow in northern Alaska, Siberia and Canada will lead to more water flowing in rivers, potentially up to 25% more under a high-warming scenario based on our research. There is more carbon in the soil in northern parts of the Arctic compared with the south. With permafrost thaw, those regions will also see more water coming into rivers from below the surface, where additional soil carbon can leach into the water and become dissolved organic carbon.

More old carbon is already showing up in samples gathered from Arctic rivers, attributed to permafrost thaw. Carbon dating shows that some of this carbon has been frozen for thousands of years.

Impacts will cascade through Arctic ecosystems

So, what does the future hold?

One of the most notable changes expected involves the transport of fresh water and associated materials, such as dissolved organic carbon and heat energy, to Arctic coastal zones.

Coastal lagoons may become fresher. This change would affect organisms up and down the food chain, though our current understanding of the potential affects of changes in fresh water and dissolved organic carbon is still murky.

River water will also be warmer as the climate heats up and has the potential to melt coastal sea ice earlier in the season. Scientists observed this in spring 2023, when unusually warm water in Canada’s Mackenzie River carried heat to the Beaufort Sea, contributing to early coastal sea ice melting.

Finally, more river water reaching the coast has the potential to freshen the Arctic Ocean, particularly along northern Eurasia, where big Russian rivers export massive amounts of fresh water each year.

There are concerns that rising river flows in that region are influencing the Atlantic Meridional Overturning Circulation, the currents that circulate heat from the tropics, up along the U.S. East Coast and toward Europe. Evidence is mounting that these currents have been slowing in recent years as more fresh water enters the North Atlantic. If the circulation shuts down, it would significantly affect temperatures across North America and Europe.

At the coast, changing river flows will also affect the plants, animals and Indigenous populations that call the region home. For them and for the global climate, our study’s findings highlight the need to closely watch how the Arctic is being transformed and take steps to mitigate the effects.The Conversation

Black bear breaks into Alaskan mall, eats a peach and relieves itself on floor before leaving: video


Can bearly believe it!

A black bear was caught on camera seemingly running errands at a local shopping mall in Anchorage, Alaska over the weekend.

A black bear in Alaska strolled through the automatic doors of the commissary mall on the military base on Sunday. Kory Godbout

The bear entered the commissary mall at Joint Base Elmendorf-Richardson around 9 a.m. Sunday, KTUU reported, citing a JBER spokesperson. 

Wild footage shows the young cub strolling through the commissary’s automatic doors and exploring all that the mall had to offer.

The hungry bear stole and ate a piece of fruit before emptying its bowels on the hallway floor on its way out of the building.

Kory Godbout, who works at the barber shop on the military base, was waiting for his first customer of the day when he spotted the furry intruder traveling through the automatic doors.

“My coworker, who is cutting hair in front of me, she yelled, ‘Bear!’” Godbout recalled. 

The grizzly bear decided to “use the restroom in the hallway” of the shopping mall. Kory Godbout

“And I looked up from my phone and the bear was walking into the barber shop right in front of me,” the barber said. “And we all ran into the break room and shut the door behind us.”

After a few minutes, Godbout and his coworkers emerged from the break room and followed the out-of-place bear into the commissary, where it took a peach from the grocery store and ate it.

But all of a sudden, the black bear returned to the barber shop.

“By that time, we were able to run back to the shop and then lock the door,” Godbout said. 

The bear cleared its bowels on the floor before leaving the shopping mall. Facebook

“And then we were watching him from the window and then that’s when he decided to, you know, use the restroom in the hallway.”

Officers from Conservation Law Enforcement attended the peculiar grizzly scene and were able to direct the wild animal towards a river and into the woods, according to the JBER spokesperson.

JBER’s wildlife program manager Colette Brandt said in a press release that the bear had triggered the automatic doors and that Sunday’s events were entirely incidental, KTUU reported.

While there has been a decline in bear-related calls since the military base installed bear-resistant dumpsters, seven bears have been put down at JBER for public safety over the past year.

Did I Find a Cure for Male Loneliness? No, But I Found a Way to Embrace Solitude in the Wild.

Did I Find a Cure for Male Loneliness? No, But I Found a Way to Embrace Solitude in the Wild.


Published July 9, 2026 03:00AM

On the longest solo trip of my life, I stepped off a two-seat float plane onto the rocky shore of Upper Twin Lake in Alaska’s Lake Clark National Park.

I had taken four flights from New Jersey to Alaska to write about the iconic cabin handbuilt by Richard “Dick” Proenneke, the self-taught naturalist whose 30-year solo life in the wilderness was captured in the beloved PBS documentary Alone in the Wilderness. Proenneke never married, never had children, and spent nearly three decades completely alone, save for the birds he fed by hand and bears that occasionally clawed at his logs.

“He must have been lonely out here,” a fellow traveler said during the park ranger’s tour of the cabin.

On that chilly June morning last year, I found myself wondering the same thing. I was just coming to a different conclusion.

Park officials told me the cabin has seen a recent uptick in visitors, which they attribute to Proenneke’s newfound popularity on social media, and to a direct flight to the property by an outback flying service. I visited the cabin as a member of a tour group led by two guides. My group included a doctor, a retired attorney, a veterinarian, and a handful of National Parks superfans. Still, I stuck mostly to myself, spending the trip deep in my own thoughts. In Alaska, I wound up pondering a life like Proenneke’s, sans the means or skills to make it happen.

According to podcasters, writers, polls, therapists, influencers, and anyone else with a mouth or keyboard, there’s a male loneliness epidemic eroding the dated fabric of masculinity, like the snake of patriarchy eating its own tail.

Remedies for this epidemic are everywhere in the media, with new ones popping up weekly. The New York Times wondered if pickleball held the answers; others have suggested buying a personal watercraft, joining a mosh pit, or taking off your shirt at a college football game, or watching a horror-comedy starring Paul Rudd. In recent months, brunch, AI-powered companion dolls, and Jack Black have been mentioned as cures.

Outside wondered whether “outdoor friendships,” volunteering, or getting a pet could work.

These cures may seem unrelated and even, perhaps, a little silly. However, the common theme between them seems to be social interaction, choosing community over individualism, a bowling league or running club over your PlayStation.

Some entrepreneurs have even launched businesses to combat male loneliness. A deep-dive earlier this year in the New Yorker revealed how fathers are paying men to turn their sons into “alphas,” while others are joining men-only retreats to be screamed at. Men are taking reams of peptides, smashing their cheekbones with hammers, and getting chin implants in an effort to chase some warped standard of masculinity.

Most of these solutions seem alien to the introverts of society, myself included. I’m not sure I’ve ever been lonely, per se, or even bored, unless I’m stuck in small talk. I’ve never loved team sports or double dates either. In school, hearing a teacher say “let’s break into groups” made me groan.

During my trip to Alaska, I realized that Proenneke enjoyed solitude but not loneliness. The former feels intentional and rewarding, as opposed to the latter, which causes anxiety and depression. He wasn’t a misanthrope. He welcomed visitors and was thoughtful enough to whittle a variety of walking sticks to match their height.

Monroe Robinson, author of The Handcrafted Life of Dick Proenneke, spent nearly 20 years living at the cabin and maintaining it for the National Park Service. Robinson knew Proenneke, who died in 2003, at the age of 86. “He liked when people came to visit,” Robinson told me later in a call, “and he also liked when they left.”

I can relate.

My aversions to crowds and clubs have been a source of personal confusion over the years. I’m not a misanthrope, either. As a reporter, I crave deeply personal interactions with others and get invested in the people I write about to a fault. Part of me always thought loneliness was a good way to avoid heartbreak. I’ve loved deeply anyhow, and lost people in my life to suicide and divorce.

In June of 2024, I learned my then-wife was deeply unhappy in our marriage. I had a real breakdown. The ensuing algorithms of online divorce content can be toxic for men, a slippery slope greased by manosphere grifters. Well-intentioned friends and family will often just take your side during a breakup, too, and there’s not much growth in that. So I tried to avoid that noise, choosing to walk inside myself, to find a “vast inner solitude” as the poet Rainer Marie Rilke advised.

I wanted to confront my own bullshit.

I spent a few dozen nights sleeping in tents for the rest of that year, mostly in the Northeast. Sometimes I slept in single-digit temperatures. I’d reserved a tent site for my wedding anniversary, a campground where I’d wanted to renew my vows. But after my marriage began to crumble, I took my young daughter, instead of canceling. I put her in a hiking backpack to slog my way up a few summits. I kept on punishing myself too, on trail runs and difficult hikes, hoping exhaustion would tamp down the urge to beg my ex and anyone who knew her for answers. Bad cell service helped with that.

(I also found a great therapist, thankfully.)

On a long-planned family vacation to Southwest Colorado in August of 2024 that I couldn’t afford and couldn’t cancel, the San Juan Mountains loomed everywhere I went. I saw them from the window of my cabin, the dirt roads I drove along with my kids, and the hammock where I finished The Snow Leopard, in which author Peter Matthiessen joins an expedition to find the mythic beast in Nepal after the death of his wife.

The mountains felt timeless and unavoidable there, and they spoke to me, a perfect epilogue to the book’s zen message.

“Accept what’s happening” they said.

And so I accepted that my marriage was over.

In May of 2025, the divorce was finalized. A few weeks later, I was in Alaska as a freelancer, pinching myself as my plane touched down on the icy, blue lake.

Robinson, when I asked, said “feeling lonely was not a thing” for Proenneke. He was too active, too busy trying to survive. Proenneke left society, yes, but he didn’t withdraw from life. In the long winters, when no sun hit Proenneke’s sod roof, when no planes landed on the frozen lake, he would spend months penning thoughtful letters to close friends, family, and his growing legion of fans.

Proenneke cared about his cabin’s appearance too, about beauty, and that matters. He built a stone fireplace, an extra bunk for guests, and hand-carved a much-beloved Dutch door. Windows would be an inconvenient luxury in a trapper’s cabin in Alaska, but Prokenneke fashioned one that offered a grand view of the lake anyway.

While I was contemplating Proenneke’s contentment in Alaska, I was also watching contentment in action with the two young guides in charge of us there. For a moment or two, I envied both of them, the same way I envied Proenneke. Guide Dom Gawel, who is in his mid-20s,  was the quieter of the two, and he led a few of us on some longer hikes while others stayed behind at camp. Later, I asked Dom about loneliness. He thought young men feel lost today “because they are comparing themselves to others in a negative way through social media” and “disconnected from nature.”

Luckily, there’s nothing close to a signal at Lake Clark National Park, no texts you feel compelled to answer, no influencers to interact with. That’s not easy to do in the United States.

I also found kinship with Dr. Adam Bolour, my kayak partner at Twin Lakes and roommate at Port Alsworth, a tiny Alaskan village on Lake Clark where we slept on our final night. We talked about fatherhood, relationships, and nature. He was traveling solo too, from California, and while he was upbeat and talkative with everyone, I watched him steal away to read some Ralph Waldo Emerson’s Self-Reliance by the lakeshore. I did the same with Proenekke’s book there.

I emailed to ask about male loneliness, when I got back to New Jersey.

“I cherish solo trips, whether I’m married, feeling alone, feeling super connected with someone or a big group,” he wrote. “It’s just great to get away and convene with silence and space.”

My revelations in Colorado and, later, at Proenneke’s cabin, helped me realize I must connect deeply with myself in the outdoors from time to time. Nature can’t just be an emergency room for me, either. It’s long-term maintenance for my physical and mental health, whether it’s trail running, floating in a swimming hole, or staring at mountains. It’s more than a hobby. The version of me who returns from those trips is a better father and, hopefully, a better partner someday.

Unlike Matthiessen, who spent months away from his young, grieving son in search of a snow leopard, or Proenneke, who spent 30 years away from almost everyone, I couldn’t and wouldn’t want to pull myself away from my children and responsibilities to that extreme. I have been guilty of that in the past. I’ll make do with a vow to see mountains like the San Juans as much as possible, even if it’s just a few days to convene with solitude, as Adam does. And if I can’t get to the Sawtooths or Switzerland, I’ll cut myself a break and keep exploring Pennsylvania or the Catskills.

A few months after I got back from Alaska, I tackled Pennsylvania’s Black Forest Trail. It’s the state’s most difficult hike, a 43-mile loop with a mind-boggling 8,500 feet of elevation gain. I was craving solitude, again, and found the trail emptier than the Alaskan backcountry. I saw as many rattlesnakes as people on that trip.

On my final night of the hike, after pushing hard for about 18 miles, I took off my boots and socks and stretched out on a shady vista as the sun began to sink.  Two hikers came in, a father and son, after their own long day. They hoped to camp there too and asked if I minded. I said it was fine and then, a few minutes later, reached for my socks and boots.

I shouldered my heavy pack, wished them a deep sleep, and pushed on to find solitude, that little bit of loneliness all the world says is a problem.
