As the commercial salmon season opens, some Alaska fishermen fear for their futures

As the commercial salmon season opens, some Alaska fishermen fear for their futures


HOMER — On a brilliant spring morning, Buck Laukitis, a longtime fisherman from this Kenai Peninsula town, stood at the city dock watching his catch come ashore.

Crew members aboard Laukitis’ boat, the Oracle, filled bags with dozens of halibut — some of the fatter ones worth $200 or more — which a crane would lift to the dock. There, processing workers on a small slime line weighed the fish, tossed crushed ice into the gills and slid them into boxes for shipment to Canada.

Harvest, unload, sell, repeat — exactly how the iconic Alaska commercial fishing industry is supposed to work. Until you ask Laukitis about the Oracle’s sister vessel, the Halcyon.

Instead of fishing for another species, black cod, like it’s built for, the Halcyon is tied up at the dock.

For Laukitis to make money, processing companies would need to pay $2.50 for each pound of black cod delivered to a plant. But right now, buyers aren’t paying much more than $1.50, he said.

With Laukitis on the dock last month were his young grandkids and adult daughters — fishermen who run a popular brand called the Salmon Sisters.

Those generations, he said, were on his mind as a sharp downturn in Alaska’s fishing industry continues looming over his livelihood. Some say that the crisis, driven by an array of market forces and economic factors outside fishermen’s control, is the biggest for the industry since statehood.

“We’re trying to do multi-generation fishing,” Laukitis said. “But believe me: It keeps me up at night, wondering about the future.”

Roughly a year into the downturn, with the major summer harvest of salmon just starting, there are some signs of recovery. Some fishermen say they managed to turn profits even after last year’s plunge in prices. And startup businesses are launching new models for processing that they say could help boost the quality and value of Alaska’s catch.

But major threats persist, many of which fishermen feel powerless to affect — posing existential risks to a $6 billion industry that employs more than 15,000 Alaskans.

Industry and state elected leaders say they expect Russia to continue selling huge quantities of fish into global markets, undercutting the prices of Alaska’s harvests — which also have to compete with farmed fish.

Inflation and high borrowing costs are hammering processing companies, which typically take out huge loans to buy supplies and stage workers and equipment at the start of each summer salmon season. Plants and whole processing businesses have shuttered around the state, while others are putting assets up for sale.

Then there’s the long-term uncertainty that comes with global warming, which appears to be boosting some fish populations but disrupting others.

Fishermen who have made big investments in recent years now own permits that could be worth a fraction of the purchase price.

Permits to participate in the typically lucrative Bristol Bay salmon fishery were going for $260,000 two years ago; now they’re selling for $140,000.

Many skippers face steep startup costs for the summer season without much confidence that their harvest will pay off. Some who are nearing retirement are having to postpone those plans until they can sell their boats and permits at higher prices.

“There are people who literally cannot afford to go fishing. They’re going to be paying money out of their own pocket to deliver their fish pretty soon,” said Maddie Lightsey, who brokers sales of permits and boats at her family business in Homer. “But they also can’t afford to sell, because the market has crashed and come down so far that they’re dramatically upside down on their loans.”

Most Alaska fishermen are in the business for the long haul, not for short-term investment returns. But some, like 41-year-old Erik Velsko, are starting to hedge their bets.

Velsko, another longtime Homer fisherman, is training to be a ship’s pilot, in case his chosen career doesn’t work out. Others said they’re looking at jobs in health care and aboard state ferries.

“That’s how much faith I have in, at least, the fisheries we’re doing,” Velsko said. “It was pretty good, for quite a while.”

‘Nothing to fall back on’

The industry turmoil first started generating big headlines after last summer’s Bristol Bay salmon harvest, when processing companies announced they would pay fishermen per-pound prices that were roughly half of the previous year’s.

The prices, which prompted vehement protests from fishermen, were the lowest in two decades, and they could end up being the lowest on record, according to a preliminary analysis by the Alaska Seafood Marketing Institute.

But the focus on salmon has, to a degree, overshadowed that the crisis is broader, covering an array of other species.

Among the biggest problems is pollock — a whitefish harvested in huge quantities in the Gulf of Alaska and Bering Sea. It’s sold into markets in Asia, Europe and the U.S. to make products like fish sticks, fried fish sandwiches and imitation crab.

Many of Alaska’s big processing companies depend on revenue from consistent, multi-season harvests of pollock to smooth out the short, frenetic summer salmon season.

But processors say that huge increases in aggressively low-priced sales of pollock products from Russia — particularly of surimi, the fish paste used to make fake crab — are crowding them out of the market, especially in Asia and Europe.

Processors say they’re also facing increased competition from Russia-caught salmon, and from farm-raised fish. Other species, like black cod, are also fetching rock-bottom prices — meaning that even fishermen who have diversified into multiple species aren’t insulated from the chaos.

“There’s nothing to fall back on. Everything, across the board, is in trouble,” Lightsey said. “This is different from other downturns in that way.”

Other dynamics that processors say are limiting the prices they can pay for fish include a historically low value of the Japanese yen against the U.S. dollar. That’s limited the demand for Alaska products in a country that’s often been a huge market.

Inflation and sharply rising borrowing costs in the past two years are also big problems.

Processing companies often take out loans of tens of millions of dollars at the start of each salmon season — money for buying empty cans and plastic, flying workers to remote plants and funding preseason boat upgrades, insurance policies and other necessities for the skippers who sell them fish.

“You had interest rates go up by three times,” said Rob Gillam, whose McKinley financial and research businesses have studied and invested in the Alaska seafood industry in recent years. “At the same time, what we can sell the fish for is going down, not up.”

Wages for processing workers, like for those in other industries, have also spiked. At a news conference last month, Joe Bundrant, the chief executive of the huge processing company Trident Seafoods, said labor costs have risen by 240% in the past five years, with diesel fuel prices also rising sharply in the same period.

“All the while that the Russians were weaponizing their seafood industry against us, we’ve seen unprecedented cost increases,” said Bundrant. His company is based in Seattle but has operated 11 plants in Alaska — four of which Trident put up for sale last year.

Deferred loans and deepening debts

Processing companies’ woes trickle down to skippers and crew, since fishermen depend on the prices those businesses can pay for their catch. Some of the same trends hitting the processing companies, like inflation, are also affecting fishermen directly.

In interviews, numerous Homer fishermen said they’re facing steep increases in the cost of insuring their boats for the summer salmon season. Jennifer Hakala, whose husband runs a boat in Bristol Bay, said the price of insurance for this year’s six-week fishery spiked to $8,000 from $5,000 in 2023.

To survive, some fishermen are deferring loan payments or taking on more debt. Others, like Hakala, are getting creative.

Typically, her husband hires two deckhands to help on the boat, but this year, they’re depending on their 16-year-old son, and Hakala, who manages a Homer marine supply store, will help out, too.

“I’m going to fly in on the peak and help them finish off the year — and hopefully we make our boat payment,” she said, referring to the yearly amount that’s due on the loan the family took out to buy their vessel.

Most fishermen in Kodiak have been able to get through the past year without contemplating difficult decisions like bankruptcy, according to Danielle Ringer, a fisherman and fisheries scholar from Homer who’s now based on Kodiak Island.

She’s heard of some skippers who have been working as crew members in fisheries they don’t normally participate in. Others are thinking about working construction instead of taking the risk of gearing up their boat for this coming summer.

“It could be OK,” Ringer said. “But not if it’s a couple more seasons like last year.”

Ringer said she’s seen support coming from the state and federal governments for large and small seafood processing companies.

Those programs are legitimate, Ringer said, but she’d also like to see more support for individual fishermen, too — ideas like direct aid, or loan forbearance. She endorsed concepts being discussed by policymakers to create new programs modeled on federal supports for agriculture.

“For healthy fisheries and healthy communities, you need all of these different aspects,” she said. “Even if government folks and others are interested in supporting fishermen, I think there are still questions about how to do that the right way.”

Not all bad news

While many Alaska fishermen are struggling, others say they have managed to stay profitable — and that they see bright spots ahead.

Last year, Homer resident Scotty Switzer and his three crew members all made money fishing off Kodiak Island, where big runs of salmon made up for the low price they were paid.

“I’m just grateful to have made something,” said Switzer, 36. “Getting into this industry, I knew there were going to be ups and downs.”

Switzer took on hundreds of thousands of dollars in loans to acquire his permit, boat and other assets, and he’s still deeply in debt. But, like other fishermen working on their boats in the Homer harbor, he said he’s not feeling too anxious about his future.

“Probably should, could,” he said. “But, I’m in it now.”

For the upcoming season, one processing company, seeking to reassure fishermen, has already announced its minimum price for Bristol Bay sockeye salmon. Silver Bay Seafoods, one of the biggest Alaska processing companies, says it will pay a minimum of 80 cents a pound, a significant bump from the 50-cent minimum it paid last year.

Meanwhile, two startup companies, Northline Seafoods and Circle Seafoods, are hoping to revolutionize the industry’s traditional freezing and salmon processing methods — thereby fetching higher prices from consumers.

Typically, processors send big boats known as tenders to collect salmon from fishermen, then motor the catch back to plants on shore, where workers are flown each summer to handle the fish and operate equipment. Delays in pickup and delivery — and sometimes less-than-meticulous handling and chilling by fishermen — can translate into lower-quality fillets.

The two companies will park new, floating factory barges directly on or near the fishing grounds, reducing the amount of transit time once salmon are caught.

Once full of whole, frozen fish, the barges will be taken back to Washington state, where the salmon will be processed throughout the offseason without requiring workers to take expensive flights to rural Alaska plants.

“We’re trying to turn it into a manufactured good, as opposed to this seasonal rush of production that’s cut by temporary seasonal workers who have never seen a fish before,” said Charlie Campbell, Circle Seafoods’ co-founder. His company has raised $36 million from investors, loans and federal tax credits, he said.

A ‘bigger, more systematic downturn’

Alaska’s congressional delegation, led by Republican U.S. Sen. Dan Sullivan, has also been chipping away at the problems of Russian pollock and salmon exports.

While the U.S. banned imports of Russian seafood in 2022, a loophole allowed those harvests to continue entering America if they’d been processed in China or other countries.

Sullivan and other Alaska elected officials successfully pressured the Biden administration to fix that problem in December; he’s also appealed directly to European Union and Asian allies to consider tighter Russian import restrictions of their own.

“When the U.S. government moves in a coordinated fashion, it can get things done,” Sullivan said. “If we got international cooperation from the EU and Japan, there’s no doubt it would stabilize prices.”

Beyond pollock and salmon, there are reasons to be hopeful about the medium- and long-term prospects for two other key Alaska species, halibut and black cod, said Norm Pillen, president of the fishermen-owned Seafood Producers Cooperative, a small processor based in Sitka.

But the near-term is less promising, with continuing low prices and high borrowing and shipping costs, he added. Sitka fishermen are also nervous about a conservation group’s request to have the federal government list Gulf of Alaska king salmon under the Endangered Species Act.

“We’re going to have another tough year to get through,” Pillen said.

Back on the Homer dock, Laukitis, the boat owner, said that last year, he thought the turmoil in the Alaska fishing industry would be short-lived, like other dips that participants have had to periodically endure over the years.

Now, he sees it differently — as a “bigger, more systematic downturn” that’s landing directly on fishermen. Processing companies may not be able to control the prices they pay for fuel or packaging, but they can reduce the price they pay for fish.

“There’s a disequilibrium,” Laukitis said. “And we’re the ones getting squeezed the hardest.”

Norwegian filmmakers’ documentary spotlights homelessness in Anchorage, aims for Alaska screening

Norwegian filmmakers’ documentary spotlights homelessness in Anchorage, aims for Alaska screening


ANCHORAGE, Alaska (KTUU) – Two Norwegian filmmakers say their debut documentary, Anchorage Welcomes You, is meant to put viewers face-to-face with people living on Anchorage streets — not to prescribe a political fix, but to “describe the situation” and the human stakes behind a crisis visible across the city.

“I think the core story is to shine a light on the prevalence of the problem that is in Anchorage when it comes to drug abuse and homelessness,” said director/cinematographer Peter Gupta. “But it’s also to show how people are … capable of taking a wrong turn in life and coming back from it.”

The documentary was shot over multiple trips to Anchorage spanning roughly two years, beginning with a summer 2022 visit, followed by a winter 2024 return and a completion last fall.

Gupta, along with editor/screenwriter Rasmus Aarskog Sætersdal, said the project first grew out of Gupta’s canoe trip down the Yukon River, where he said he saw “communities ravaged by drugs and alcohol.”

“I canoed the whole length of the Yukon in 2017,” Gupta said. “And I saw what was going on in all the villages. And I wanted to go back and make a film at some point.”

Gupta said he met Anchorage resident Erinn Leann — a central figure in the film — at the end of that trip and told her then he planned to return to Alaska to make a documentary.

A title drawn from a sign — and the ‘duality’ beneath it

The film’s title comes from the weathered “Anchorage Welcomes You” sign seen by commuters entering the city — and, the filmmakers said, from what they described as the contrast between Anchorage’s image and the encampments they saw nearby.

“It was interesting when we were there the first year and we saw this Anchorage welcomes sign falling apart and a whole … camp growing up beneath it,” Sætersdal said. “And it was just this … you can say duality of presentation for the city.”

Gupta said the pair debated keeping the name, but after multiple test screenings they found Alaskans preferred the working title.

“We’ve had ambivalent feelings about the title of the film because it’s kind of tongue in cheek,” Gupta said. “We didn’t want to keep it at some point, but the people from Anchorage really wanted to keep it.”

Building trust — and setting rules

Much of the film unfolds in intimate, up-close moments that are hard to capture in traditional daily news reporting.

Sætersdal said filming required clear rules and consent. He said the filmmakers spent time walking the same routes and meeting the same people repeatedly. Gupta added that trust was foundational.

“I think it’s so important, that respect for whoever is participating, that’s a prerequisite for bringing them into the project,” he said.

Anchorage through outsiders’ eyes

Asked what makes homelessness in Anchorage distinct, Gupta said his travels shaped his perspective. Gupta described what he called “social fragmentation” and “hopelessness” — a situation he said can be more than just a lack of material resources.

“I’ve been around the world,” he said. “And the poverty in the United States is different.

“When you go to the United States, there’s a social fragmentation in a way that is quite unique. And I think there is a hopelessness and a different character to it … it’s not only a material problem. It is also a social problem.”

Sætersdal added Alaska’s identity as a frontier draws people seeking escape.

“Alaska still has this mythical place in imagination as the last frontier,” he said. “You see also people coming from all over the country … coming to Alaska in escapism of something. And then there’s nowhere else to go.”

‘Not to tell the people of Anchorage what to do’

Gupta and Sætersdal said they hope the documentary sparks conversations without presenting a single prescribed solution.

“What we’re trying to do with this film is not to tell the people of Anchorage what to do about homelessness,” Gupta said. “It’s about describing what’s happening and sparking a conversation.

“We hope that we can kind of make the homeless appear as resourceful and also capable of changing. But it’s not down to us what to do with it.”

Returning to Anchorage — and trying to bring the film home

Now, the two say the hope is to screen it in Alaska — and eventually get broader U.S. distribution. They said navigating distribution has been its own grind, but Sætersdal added that Alaska continues to pull at them creatively.

“Alaska really is a place that it sticks to you,” Sætersdal said. “You can’t unsee it once you’ve been there and you can’t like brush it off. It becomes a part of you.”

10 Reasons the 2026 Princess Cruises Season Is the Ultimate Alaska Power Move – AOL

10 Reasons the 2026 Princess Cruises Season Is the Ultimate Alaska Power Move – AOL


Alaska already has glaciers, whales, old gold-rush towns, wild seafood, and mountains. But Princess Cruises is taking the year by storm with something bigger than a standard summer schedule. The line is sending eight ships to Alaska, adding new North-to-Alaska programming, and giving travelers more ways to turn their trip into a full land-and-sea adventure.

Princess Is Going Bigger Than Ever

The 2026 Alaska season gives Princess its largest presence in the region to date, with eight ships, 180 departures, and visits to 19 destinations. Travelers are not boxed into a narrow route or one small batch of dates. The ship lineup includes Star Princess, Coral Princess, Royal Princess, Ruby Princess, Grand Princess, Emerald Princess, Discovery Princess, and Island Princess. For anyone comparing Alaska cruise options, that much capacity means more itinerary choices.

Star Princess Gives The Season A New Headliner

Star Princess is the newest ship in the Princess fleet. This matters because Alaska cruising can easily feel like a trade-off between destination and ship experience. Princess is putting one of its newest vessels into one of its most important regions. Star Princess also hosts the new Après Sea experience inside The Dome, a high-positioned venue designed around big views.

Glacier Days Get The Full Main-Event Treatment

Glacier viewing has always been one of Alaska cruising’s biggest draws, but Princess is giving it extra structure through “The Glacier Experience: A Signature Princess Day.” On select Glacier Bay sailings, guests get close-up glacier views, live narration, and Park Ranger commentary from the bridge and open decks. There are also theater presentations and Junior and Teen Ranger programming. VIP viewing areas and bowfront access add another layer for guests who want the best possible look at the ice.

The Trip Can Extend Deep Into Alaska By Land

Princess has long built part of its reputation around cruisetours that combine time at sea with inland travel. A seven-night sailing can deliver a strong Alaska trip in itself. However, inland travel opens the door to scenic train journeys, Princess Wilderness Lodges, and routes to places such as Denali, Kenai, and the Mt. McKinley lodge area. The 2026 season continues to lean into sea-and-land travel.

North To Alaska Makes The Ship Feel Local

Princess first introduced its North to Alaska program in 2015, and in 2026, every Princess ship sailing in Alaska will carry the new programming. The whole idea is to bring local culture, food, personalities, and storytelling on board so guests learn something about Alaska between ports. This includes Native Alaskan speakers, naturalists, enrichment presenters, and destination-focused events that connect the trip to the place outside the ship. Names in the speaker series include Tlingit voices, Alaska Native educators, writers, and photographers.

Alaska Seafood Gets A Bigger Seat At The Table

Princess is leaning into Alaska’s food identity with “A Taste of The Great Land.” The 2026 specialty restaurant offerings feature sustainably sourced, wild-caught Alaskan seafood created with regional suppliers. Crown Grill offers dishes such as Wild King Salmon, Alaskan Jumbo Lump Crab Cake, and Jumbo Lump Crab paired with Butter-Broiled Lobster Tail. Sabatini’s Italian Trattoria also brings Alaskan fish into an Italian-style setting.

The Entertainment Has Alaska In Its Bones

This season also features “Candlelight Concert Series: Fire & Ice,” with Alaska singer-songwriters performing in a candlelit setting twice per voyage. This gives the onboard entertainment a stronger sense of place than a generic music night. Returning favorites add a livelier side, including Great Alaskan Lumberjack Show elements with axe-throwing recruits, trivia, and timber-sports storytelling tied to Ketchikan. Select sailings also feature Deadliest Catch captains and crew members sharing Bering Sea crab-fishing stories. The lineup draws from Alaska’s labor, music, weather, and folklore.

Families Get More Than A Pretty View

Younger travelers are getting special attention, not a watered-down version of the adult trip. Glacier Bay Junior Rangers let kids complete activity books, attend presentations, and earn a badge and certificate through a partnership with the National Park Service. Gold Rush Adventures pulls families into a shipwide Klondike-style search, while Great Alaskan Expedition offers youth and teens a three-hour team-based experience across land, sea, and air. As puppies in the Piazza also return on ships visiting Skagway, guests get to see Alaskan Huskies and sled-dog culture.

Après Sea Gives Alaska A Stylish Cooldown

After a long day outside, Princess is adding a dedicated wind-down ritual through Après Sea. The setup is inspired by après-ski culture. Guests can expect warm drinks, happy hour, and panoramic views after they return from exploring. On Star Princess, the experience is in The Dome, and it provides a strong visual setting at the top of the ship. A relaxed lounge concept gives the evening its own personality, and guests don’t have to jump straight from adventure into dinner.

MedallionClass Keeps The Whole Trip Moving Smoothly

Alaska days can get busy fast, with early excursions, glacier viewing, dinner plans, family meetups, and plenty of time spent moving around the ship. The Princess Medallion Class setup helps cut down on small hassles. The wearable Medallion supports contactless boarding, keyless stateroom entry, onboard ordering, contactless payment, ship navigation, and locating travel companions through the app. When the day already includes ports, wildlife, ice, and dinner reservations, fewer friction points onboard can make a real difference.

Hantavirus outbreak, climate risks from microplastics and Alaska’s surprise tsunami

Hantavirus outbreak, climate risks from microplastics and Alaska’s surprise tsunami


Rachel Feltman: Happy Monday, listeners! For Scientific American’s Science Quickly, I’m Rachel Feltman. Let’s kick off the week with a quick roundup of some science news you may have missed.

First, you may have seen some headlines last week about an outbreak of hantavirus on a cruise ship. Here to tell us more about what happened is Tanya Lewis, SciAm’s senior desk editor for health and medicine.

Tanya, thanks so much for coming on to walk us through this.

Tanya Lewis: Yeah, no, thanks so much for having me.

Feltman: Why are we talking about hantavirus and this cruise ship? What happened?

Lewis: Just to catch people up, this outbreak was first noticed about a week ago on a ship called the MV Hondius, which was a cruise ship departing from South America, Argentina. And the people that were sickened and unfortunately passed away, two of those individuals were a married couple who had been traveling—it was a Dutch couple—we think were infected in Argentina and then boarded the ship. And then subsequently, multiple other people have been infected. As of May 7 the number of people on this cruise ship who had been infected with hantavirus was eight people. So that probably could still change.

But you might not have heard of hantavirus before, but it is a virus family that people have been sickened with before, and it’s generally spread by rodents, like rats or mice. And this commonly happens in places where people are exposed to the feces of these animals.

And it causes pretty severe disease. It can cause anything from respiratory distress and fluid in the lungs to some forms of it can be more of, like, a hemorrhagic fever, kind of like Ebola. But the kind that we’re seeing on this cruise ship is more the respiratory kind.

But yeah, this is a virus that, while it is fairly rare to be infected with it, it’s quite lethal. The estimates of its lethality vary, but anywhere from, like, 30 percent to even 50 percent of people infected have died of it.

Feltman: Right, well, and like you said, it, it’s usually spread through rodent feces. But unfortunately, the specific virus we’re talking about, with regard to this cruise ship, is one of the rare instances where it is technically possible to spread from human to human. Can you tell us a little bit more about that?

Lewis: Basically, these individuals on the ship were thought to be infected by human-to-human transmission. At least, that’s the working hypothesis right now. And the reason has to do with the exposure routes.

As I mentioned two of the people were a married couple, so we’re talking about, like, very close contact. This is not something like SARS-CoV-2, the virus that causes COVID, where it’s, like, in the air and wafting around for hours or something. This is something that you would probably need to be, like, breathing very closely, in the same space. And of course, cruise ships are, like, kind of the perfect petri dish for that.

Feltman: Yeah.

So I think there are two things to talk about. There’s, one, why experts are not immediately super concerned about pandemic potential from this specific thing, but also why it is reasonable that I think so many of us, when seeing this news, went, “Uh-oh. We’re—this is a reminder of public-health paradigms I do not wanna be reminded of.”

So let’s start with the good news: Why are experts not freaking out about this?

Lewis: Yeah, so we have to remember that this is a virus that is very different than a lot of the pathogens that have caused respiratory pandemics in the past. In order for a pathogen to be a major pandemic concern, it needs to be very transmissible, and that is something that we have not yet seen with this hantavirus.

I should say, this particular strain is the only strain that has been shown to transmit human to human; it’s called the Andes strain. Most hantaviruses are not thought to spread that way. So the good news is, it’s kind of rare. The bad news, maybe, is that it does appear to have spread, at least, you know, in a limited way, between people.

But yeah, in terms of why experts are not, like, immediately concerned that this will spark a larger epidemic, I think the reason is just that this type of virus and the way it spreads is not conducive, as far as we know, to that type of outbreak. And it’s also happening in a very contained space, so although there have been reports that several of the people on board the ship have disembarked and we are still following that closely, at this point there is no indication of wider community spread, which is what we call it when people are getting infected who have not had direct exposure to the infected individuals.

Feltman: Is there any concern that the time that this virus spent, you know, in such a perfect petri dish may have given it the opportunity to mutate and be better at jumping from person to person?

Lewis: I think what virologists would tell you is, like, the more opportunities a virus has to jump between people, the higher the risk of it developing, like, a concerning mutation that makes it more transmissible.

That said, we’re still talking about a relatively small number of individuals. I mean, eight people sounds like a lot, but, you know, when you’re talking about this being very close quarters on a ship, this is not like, oh, you’re walking into a giant city like New York City and infecting everyone around you or something. So I think that is a little bit reassuring, perhaps, at this point.

But that said, we’ve been humbled before, and I think if there’s one lesson we can take from the COVID pandemic, it’s that we shouldn’t panic, but we should definitely pay attention. And at least scientists wanna know and learn more about this virus and understand it better.

Feltman: I think a lot of people are getting a little freaked out by this news. [Laughs.]

Advertisement

Lewis: Yeah, and I mean, I would be the first to say, like, something like this you hear about, it’s, like, instantly puts you back in that fearful space of 2020. And of course, there was the famous cruise ship, the Diamond Princess, where some of the early COVID cases happened. So that is always concerning.

On the other hand, you know, we have to sort of put it in perspective and remember this is a rare virus and it is something that people have been infected with in the past, so it’s not a completely new virus, unlike SARS-CoV-2, which we had never seen before. So we do have some idea of how this virus works, and while we don’t have any specific treatments for it, we do at least have experts who study it. So that should hopefully give some reassurance that, like, this is not a complete unknown. We are not starting from square one.

Feltman: Thanks for that, Tanya.

Now, listeners, keep in mind we had this conversation on Thursday, May 7. But you can always go to ScientificAmerican.com for more up-to-date science news.

Now for new research on micro- and nanoplastics—but this isn’t the health story you might be expecting. According to a study published last Monday in Nature Climate Change, these tiny bits of broken-down plastic could be contributing to our planet’s warming temperatures.

For starters, just in case you are blissfully unaware: yes, there are, unfortunately, microplastics in the sky. According to a study published in 2021, some of these particles swirl up into the air from the road, where tires and brakes frequently shed small pieces of plastic.

Now, the idea of microplastics permeating the air and even seeding clouds into existence is creepy enough, in my opinion. But this new study suggests they can also have a warming effect on the atmosphere.

Here’s how that would work: if you’ve ever spent time on a patch of blacktop on a sunny summer day, you know that black material absorbs heat. Conversely, white material reflects heat. The same thing happens when you scatter bits of dark and light plastic into the atmosphere, which is what humanity has inadvertently done quite a bit over the past few decades.

Unfortunately, according to this new study, any cooling effects we might get from light microplastics are probably vastly outweighed by the warming effects of dark microplastics. While the estimated effect is a small percentage of the warming fueled by soot from coal power plants, the results are still worrying.

As Jackie Flynn Mogenson reported for SciAm last week, we don’t actually know the concentration of micro- and nanoplastics currently in our atmosphere. But the authors of the new study argue that global climate assessments should do more to factor in these tiny plastic bits. And their findings serve as a great reminder that when we talk about the downsides of plastic, we should recognize that there may be impacts far less concrete and obvious than creating growing piles of trash in landfills.

Now I’ll turn the mic over briefly to SciAm’s chief newsletter editor, Andrea Gawrylewski. She’s gonna tell us about the science behind a tsunami that caught Alaska by surprise.

Andrea Gawrylewski: Thanks, Rachel.

Last summer, in August, a small cruise boat called the David B spent the night in an inlet about 50 miles from Juneau, Alaska. They were supposed to be at anchor nearer to Juneau in this beautiful fjord called Tracy Arm, but bad weather had forced them to pick another place to stay. And it turns out that detour may have saved their lives.

In the morning, from where they were anchored, the boat’s owners noticed seawater rolling over the nearby [sandbar] and shoreline. It was weird because the tide was supposed to be out at that time, and they had no idea why the water was so high.

When scientists heard about the strange sea-level rise, they began examining seismic data, they looked at aerial footage and satellite images, and determined that a massive landslide had occurred at the top of the Tracy Arm fjord.

So what had happened?

The South Sawyer Glacier at the top of Tracy Arm has been steadily shrinking and retreating for the last 25 years. In the spring and summer of last year the ice retreated inland several hundred feet, exposing so much bare rock that it ultimately caused a landslide.

That big slide hit the water and sent a tsunami racing through the fjord—like, so much water that the tsunami surged more than 1,500 feet up the sides of the fjord and sloshed back and forth, like in a bathtub.

That event also produced a seismic signal equivalent to a magnitude 5.4 earthquake. Scientists found smaller seismic events in the data that had occurred at least 24 hours before the big one, and they were increasing exponentially in intensity in the six hours before the landslide.

So now the question is: Could these early seismic signals be used as a warning system? One scientist at the Alaska Earthquake Center has been testing a landslide detection algorithm, and so far it’s detected 35 landslides in near real time. Sending out warnings within three to four minutes of big events could make all the difference to people who live in the area, so scientists are working to improve tools like these.
