Ecosystem shifts, glacial flooding and ‘rusting rivers’ among Alaska impacts in Arctic report

The National Oceanic and Atmospheric Administration issued its annual Arctic Report Card on Tuesday, which documents the way rising temperatures, diminished ice, thawing permafrost, melting glaciers and vegetation shifts are transforming the region and affecting its people. The agency has released the report for 20 years as a way to track changes in the Arctic.

“The Arctic continues to warm faster than the global average, with the 10 years that comprise the last decade marking the 10 warmest years on record,” Steve Thur, NOAA’s acting administrator for oceanic and atmospheric research and the agency’s acting chief scientist, said at a news conference Tuesday.

The report card is a peer-reviewed collaboration of more than 100 scientists from 13 countries, with numerous coauthors from the University of Alaska Fairbanks. It was officially released at the American Geophysical Union’s annual meeting in New Orleans, where Thur and other officials held the news conference.

The report is the first under the second Trump administration, at a time when the federal government’s commitment to documenting Arctic climate change has diminished: The president has repeatedly called climate change a hoax and federal departments are cancelling climate change-related research and projects, as well as scrubbing climate information from public view.

Under directives from the Trump administration, NOAA no longer provides information that the National Snow and Ice Data Center once used to monitor sea ice and snow cover, for example. The Colorado-based center now relies on satellite information from the Japan Aerospace Exploration Agency for its sea ice reports, and it has reduced its analysis.

A national dataset about the melt of the Greenland Ice Sheet has also been lost to the Trump administration’s cutbacks, said Rick Thoman of the UAF’s Alaska Center for Climate Assessment and Preparedness, one of the report’s main editors. The ice sheet is still being monitored by European satellites, but the data is not equivalent, he said.

Government entities like NOAA’s Alaska Fisheries Science Center, which regularly provides scientific information that goes into the Arctic Report Card, have endured deep budget cuts and staff firings.

On Tuesday, Russel Vought, President Donald Trump’s Office of Management and Budget Director, said the administration plans to close the National Center for Atmospheric Research, a Colorado research facility that has operated since 1960. The facility “is one of the largest sources of climate alarmism in the country,” Vought said in a post on the social media site X.

And this year, unlike the other years since 2006 when NOAA published the first Arctic Report Card, the agency declined to issue a news release about it.

Thur, asked if NOAA will continue to publish report cards in the future, said the agency will continue the work that goes into the annual documents.

“What I would say in response to that question, is that we’re here today and that we have released the 2025 version,” he said. NOAA has continued its long-term environmental observations in the Arctic, both with satellite observations, he said. “So I think one of the things that the community can rely upon is that our efforts to continue to observe the planet will remain present,” he said.

Thur also demurred when asked whether NOAA still stands by the statements about fossil fuels made by the agency’s prior administrator, Rick Spinrad. When last year’s report was issued at the end of the Biden administration, Spinrad said the changes in the Arctic were directly related to fossil-fuel emissions. Thur did not mention fossil fuels.

“What I would say in response to that question is that we recognize that the planet is changing dramatically,” he said during the news conference. “Our role within NOAA is to try to predict what’s going to occur in the future by documenting what’s occurring today,” he said. “There is a human role, as our administrator currently, Dr. Neil Jacobs, said during his congressional confirmation hearing, for humans in influencing those changes.”

Matthew Druckenmiller of the National Snow and Ice Data Center, another lead editor of the report, made no such equivocations.

“Let us start by first acknowledging that the warming of our planet driven by human greenhouse gas emissions into our atmosphere is amplified in the Arctic,” he said near the start of the news conference. “The Arctic continues to warm much faster than the globe overall, amplified by the loss of reflective sea ice and snow, causing more of the sun’s heat to penetrate into land and ocean.”

Druckenmiller also said the Trump administration did not interfere with drafting of the report.

“I can say that in producing the Arctic report card in 2025, we did not receive any political interference with our results,” he said.

Lower sea ice, more  precipitation, more melt and thaw

Some of the main messages in this report concern superlatives, while others describe a continuation of long-term changes.

It was the Arctic’s hottest year in a record dating back to 1900, the report said. The past year’s winter sea ice maximum was the lowest in the satellite record, which dates back to the late 1970s, and sea ice is much thinner and younger than it was in the past, the report said.

The region set a record for precipitation for the 12 months that ended in September, despite an unusually dry summer in parts of northern Canada and Eurasia. Warmer air holds more moisture, and a long-term trend of higher precipitation continues, the report said.

Across the Arctic, June snow cover extent has declined by 50% over the past six decades, since the 1960s. “Even though you’re starting out in season with more snow, it’s melting faster,” Thoman said.

For rain, there is another pattern: more heavy rain events. Those included last January’s powerful, northward pushing “atmospheric river” that stretched from the Aleutian Islands through mainland Alaska, bringing midwinter rain and flood conditions to Anchorage and elsewhere.

Alaska figures prominently in this year’s report card, as it has in past years’ reports.

One chapter is devoted to changing conditions in the Northern Bering Sea and the Chukchi Sea, where a warming-related process termed “borealization” is ongoing. That refers to the transition from an Arctic ecosystem to a more southern ecosystem.

In both seas, the report said, boreal species ranging from commercially important fish like Alaska pollock and Pacific cod to tiny organisms that make up the base of the food web, have been pushing out the more cold-adapted Arctic species like Arctic cod, saffron cod and snow crab. There are impacts to people and marine mammals, the report noted.

“Warming temperatures, declining sea ice, and shifting productivity in the Chukchi and northern Bering Seas drive ecosystem changes with significant implications for fisheries, food security, and Indigenous subsistence,” the report said.

In both seas, about a third of the boreal species groups examined over time increased, while about a third of the Arctic species groups decreased. Some of those boreal species populations spiked in recent years. That long-term trend is evident despite a lot of year-to-year variation and anomalously cold conditions in the Chukchi over the past year.

A chapter about mountain glaciers, a major contributor to global sea level rise, highlights this summer’s glacial outburst flood in Juneau, a phenomenon that has become an annual occurrence in Alaska’s capital city. Glacial outburst floods are increasing in frequency and severity in certain parts of the Arctic and subarctic, said Gabriel Wolken of UAF at the news conference.

Glacial melt is also tied to another extreme event that happened this summer in Southeast Alaska: the collapse of a mountainside along narrow Tracy Arm, which generated a local tsunami that rose nearly 1,600 feet up the opposite side.

“Glacier retreat combined with slope instability can lead to landslides,” Wolken said, adding that those slides can lead to far-reaching tsunamis. “The August 10th, 2025 landslide in Southeast Alaska’s Tracey Arm illustrates the sheer power of these hazards,” he said.

A chapter in the report is devoted to “rusting rivers,” a permafrost-related phenomenon documented throughout the Arctic but especially in Northwestern Alaska. The name comes from the conversion of clear streams to rust-colored waterways, the product of iron and other chemicals that leech out from rocks because of permafrost thaw. There are more than 200 such rusting watersheds in Alaska, said Abagael Pruitt, a University of California, Davis scientist studying the subject.

Another chapter in the report describes the Indigenous science monitoring being done at the community level. That includes work by the Aleut Community of St. Paul Island, a tribal government that has established its own lab to screen traditional foods for mercury contents.

While much of the report was devoted to impacts within the Arctic and to people living in the region, its coauthors pointed out that rapid climate change in the far north affects latitudes far to the south. Sea level rise, disrupted weather patterns and shocks to commercial fisheries that are important global food sources are among the far-ranging effects of melt, thaw and other changes, they said.

Wolken, at the news conference, put it this way:

“From the deep oceans to the highest peaks, the Arctic cryosphere is undergoing rapid, interconnected and unprecedented change, and those changes matter far beyond the Arctic.”

UAS lecture highlights rapid warming and ecological shifts in the Arctic

By: Grace Dumas, News of the North

The University of Alaska Southeast spotlighted rapid Arctic environmental change at its Evenings at Egan lecture Friday, featuring UAS’s new professor of forest ecology, Dr. Logan Berner.

His research tracks how northern ecosystems are reshaping in a warming world.

Berner, who grew up in Gustavus and studied as an undergraduate at UAS before returning as faculty.

“Growing up on the edge of Glacier Bay National Park, you know, you’re right there on the edge of the Arctic.” Berner said, “Seeing glaciers receding and these mounting impacts of climate change in Southeast Alaska was something that really drew me to the science of forest ecology and global change ecology.”

Berner said the Arctic has warmed three to four times faster than the rest of the planet, in recent decades.

“This long term warming trend has had all sorts of impacts on these northern ecosystems, which are otherwise the coldest ecosystems that we have on our planet.” Said Berner, “Not surprisingly, as temperatures rise, we see all sorts of ecological impacts occurring. We see trees and shrubs expanding across northern landscapes. We see impacts on wildlife as habitat changes, and all of that then influences people who live in the North as well as broader global society.”

Berner said caribou populations have declined by more than 60% across much of the Arctic in recent decades as expanding shrubs outcompete lichens crucial to winter forage

However, he said species tied to woody habitat, moose and beaver, are pushing north and, in some cases, reaching Alaska’s Arctic coast.

“It’s not all necessarily doom and gloom in terms of wildlife change, right? while caribou might be really suffering under these warmer, shrubbier environments, moose and beaver are thriving.” He said, “The animals that are historically more used to living in the boreal forest, it’s been possible for them to expand northward, up into the Arctic tundra, as those northern landscapes have become progressively dominated by woody plants.”

While Berner says not all change is negative for wildlife, the pace of transformation requires careful attention.

Berner’s work combines field ecology, satellite remote sensing, and ecological informatics to understand terrestrial ecosystems in the warming world.

His past research projects included field work in various parts of Alaska, as well as northern Canada, Finland, and Russia.

Though his work primarily centers the Arctic, Berner says Juneau serves as a point of research at the ‘edge of the Arctic.’

“If you go up into the mountains around town, these are Arctic tundra ecosystems, they’re fingers of mountain ranges that push out of the Arctic and have many of the same plant communities as you find in the more polar north.” Berner said, “Juneau really is part of the Arctic ecologically. Juneau offers a unique opportunity to study those changes in those kinds of ecosystems at the edge of the Arctic, and there are certainly folks at UAS who are studying various aspects of ecosystems around Juneau, from changes in Glacier dynamics, outburst floods, to wildlife populations, to the kind of biogeochemistry of rivers. There’s a lot of research that happens at UAS focused on understanding ecosystems at the edge of the Arctic.”

UAS’s Evenings are free to the public and have accessible attendance options including livestreams.

The series concludes Dec. 12 with a “Winter Fire Showcase” of local writers and artists.

Republicans vote to roll back Biden-era restrictions on mining and drilling in Alaska

AP- Congressional Republicans have voted to roll back restrictions on mining, drilling and other development in three Western states, including Alaska advancing President Donald Trump’s ambitions to expand energy production from public lands.

Senators voted 50-46 Thursday to repeal a land management plan for a large swath of Alaska that was adopted in the final weeks of Democratic President Joe Biden’s administration. Lawmakers voted to roll back similar plans for land in Montana and North Dakota earlier this week.

The timing of Biden’s actions made the plans vulnerable to the Congressional Review Act, which allows Congress to terminate rules that are finalized near the end of a president’s term. The resolutions require a simple majority in each chamber and take effect upon the president’s signature.

The House approved the repeals last month in votes largely along party lines. Trump is expected to sign the measures, which will boost a proposed 211-mile road through an Alaska wilderness to allow mining of copper, cobalt, gold and other minerals.

Trump ordered approval of the Ambler Road project earlier this week, saying it will unlock access to copper, cobalt and other critical minerals that the United States needs to compete with China on artificial intelligence and other resource development. Copper is used in the production of cars, electronics and even renewable energy technologies such as wind turbines.

The road was approved in Trump’s first term, but was later blocked by Biden after an analysis determined the project would threaten caribou and other wildlife and harm Alaska Native tribes that rely on hunting and fishing.

The Biden-era restrictions also included a block on new mining leases in the nation’s most productive coal-producing region, the Powder River Basin in Montana and Wyoming. On Monday, the Trump administration held the biggest coal sale in that area in more than a decade, drawing a single bid of $186,000 for 167.5 million tons of coal, or about a tenth of a penny per ton.

Trump has largely cast aside Biden’s goal to reduce climate-warming emissions from the burning of coal and other fossil fuels extracted from federal land. Instead, he and congressional Republicans have moved to open more taxpayer-owned land to fossil fuel development, hoping to create more jobs and revenue. The Republican administration also has pushed to develop critical minerals, including copper, cobalt, gold and zinc.

A decision on whether to accept the recent bid from the Navajo Transitional Energy Co. is pending, and the lease cannot be issued until the Montana land plan is altered. The dirt-cheap value reflects dampened industry interest in coal despite Trump’s efforts. Many utilities have switched to cheaper natural gas or renewables such as wind and solar power.

Administration officials expressed disappointment that they did not receive “stronger participation” in the Montana sale. In a statement, Interior Department spokesperson Aubrie Spady blamed a “decades long war on coal” by Biden and former Democratic President Barack Obama.

Republican Sen. Tim Sheehy of Montana said the repeal of the land-management plan in his state was “putting an end to disastrous Biden-era regulations that put our resource economy on life support.”

Republican Sen. Dan Sullivan of Alaska called the Biden-era plan for 13 million acres in the central Yukon region “a clear case of federal overreach that locks up Alaska’s lands, ignores Alaska Native voices … and blocks access to critical energy, gravel & mineral resources.”

The GOP legislation “restores balance, strengthens U.S. energy & mineral security and upholds the law,” Sullivan said in a statement.

Democrats urged rejection of the repeals, arguing that Trump’s fossil fuel-friendly agenda is driving up energy prices because renewable sources are being sidelined even as the tech industry’s power demands soar for data centers and other projects.

“We are seeing dramatic increases in the price of energy for American consumers and businesses and the slashing of American jobs, so that Donald Trump can give an easy pass to the fossil fuel industry,” Democratic Sen. Tim Kaine of Virginia said Wednesday on the Senate floor.

Last week, the administration canceled almost $8 billion in grants for clean energy projects in 16 states that Democratic presidential candidate Kamala Harris won in the 2024 election.

Ashley Nunes, public lands specialist at the Center for Biological Diversity, an environmental group, said Republicans were unleashing “a wholesale assault on America’s public lands.” Using the Congressional Review Act to erase land management plans “will sow chaos across the country and turn our most cherished places into playgrounds for coal barons and industry polluters,” she said.

In Alaska, a graphite mine races toward approval without the required tribal consent

By: Lois Parshley, Grist

This story was originally published by Grist and Alaska Public Media. Sign up for Grist’s weekly newsletter here.

The Kigluaik Mountains stretch across the Seward Peninsula of western Alaska like a spine, their jagged ridges keeping a record of time. The Inupiaq have long read these ridges and valleys as a living story: Fire and fracture have marked the rock, and glaciers’ slow grind polished it. The talus slopes gleam in the low fall sun, meltwater from the snowfields spilling into streams that thread across the map of caribou trails on the tundra below.

Hidden beneath these remote valleys lies one of the world’s largest known graphite deposits. Over millions of years, carbon deep within the earth was subjected to immense heat and pressure, forming crystalline sheets black and soft as pencil lead. Canadian company Graphite One plans to mine the valuable material for batteries and strategic minerals — despite many residents’ objections, and so far, without the federally required tribal consultation with the nearby communities of Teller, Brevig Mission, and Mary’s Igloo.

The area slated for development drains into Imuruk Basin, an estuary fed by four rivers that create one of the continent’s most biodiverse ecosystems. This vital hunting and fishing area is essential to residents’ food security and the traditions that tie them to the land. As Lucy Oquilluk, president of Mary’s Igloo Traditional Council, told the federal government, sidelining her community denied it “the opportunity to have our voice heard on issues that directly impact our communities and ways of life.”

After President Trump invoked emergency powers to produce critical minerals this spring, the federal government fast-tracked the mine’s permitting. Three of the four local tribes have vehemently opposed the project, and say the public review process has been short-changed. (The fourth, Nome Eskimo Community, has not joined the opposition, and did not respond to an interview request.)

In June, Graphite One became the first Alaskan mine — and among the first in the country — to qualify for FAST-41, a process that expedites federal approval of critical infrastructure. This hastens environmental reviews to as little as 30 days. The complex choreography of federal permits — spanning the Army Corps of Engineers, the Bureau of Land Management, and the Fish and Wildlife Service — is now moving with unprecedented speed.

The company, which did not respond to requests for comment, envisions carving a sprawling operation into the Kigluaik: To access the remote site, it will need to use 30 miles of public road and lay 17 miles of new road, cutting across salmon streams and archaeological sites. It plans to truck the ore year-round over public roads to a temporary holding facility in Nome until a deep-water port can be built. From there, the material will make its way to Ohio, where the company plans to build a processing facility on a brownfield once used by the Department of Defense.

Graphite supply is vital to both the battery industry and national defense, and China dominates the global market. Company CEO Anthony Huston said the site “is the perfect home for the second link in our strategy to build a 100-percent U.S.-based advanced graphite supply chain.” Yet the company plans to rely on a Chinese manufacturer, Hunan Chenyu Fuji New Energy Technology Co., for design, construction, and operations — underscoring how even “domestic” supply chains remain tied to global networks and exposed to geopolitical risks.

On the strength of its promises to reduce reliance on overseas sources, the venture has received significant subsidies. In 2019, Republican Governor Mike Dunleavy nominated it as a high-priority infrastructure project, streamlining permitting. Four years later, Graphite One secured pivotal support from the U.S. Department of Defense. With funds from the Inflation Reduction Act, the company received a $37.5 million grant to expedite its feasibility study. Framed as a national security measure under the Defense Production Act, the funding aimed to develop domestic supplies of critical minerals. The resulting analysis estimated the mine could generate $43 billion in revenue for the Canadian company. In 2023, Graphite One received an additional $4.7 million from the Defense Department to develop a foam fire suppressant. Earlier this month, the company received $570 million from the Export-Import Bank of the United States, the official credit agency of the federal government.

This kind of governmental support has helped fuel a surge in mining across Alaska, where state officials are encouraging rapid development. Dunleavy recently decreed that if a state agency misses a permitting deadline, the project gains automatic approval — raising concerns of a regulatory free-for-all. Earlier this month, for example, the state approved a United States Antimony Corporation operation near Fairbanks, just three months after the company acquired the mine, saying it met permitting exemptions under state law.

In Graphite One’s case, fast-tracking has pushed tribal input to the margins. In September 2023, the tribal governments of three Inupiaq communities sent letters to the U.S. Department of Defense, protesting the fact they had not been consulted as legally required before the agency funded the project’s feasibility study. It did not respond until the White House intervened. “After the fact doesn’t count,” said Austin Ahmasuk, a Nome Eskimo Community tribal member.

During a Zoom meeting more than a year later, the department finally acknowledged the oversight, but the tribes report they never received the promised meeting notes or any follow up. The feasibility study the company produced with that federal funding explicitly tries to exclude tribes as “cooperating agencies,” limiting their ability to influence project planning and environmental assessments. (The U.S. Army Corps told Grist this was incorrect, and that relevant tribal entities have been invited into the FAST-41 process.) All of this “violates free, prior, and informed consent,” Ahmasuk said, referring to a requirement under the U.N. Declaration on the Rights of Indigenous Peoples, or UNDRIP, that tribes be consulted and involved in any decisions affecting their lands.

A similar pattern is emerging with the U.S. Army Corps of Engineers. It initially estimated an environmental review would take over two years, but after a 2023 Supreme Court decision narrowed the definition of “waters of the United States,” the agency reduced the review’s scope, despite the company’s plans to expand the size of the mine, and accelerated its timeline. Tribes have insisted on the required consultation before this permit is issued, and while the Corps has agreed in principle, Graphite One submitted an application in August, while a meeting has not yet been confirmed. These expedited reviews, said Hal Shepherd, a consultant who works with tribes on water policy, turn consultation from a meaningful process into a bureaucratic checkbox. “Even if consultation does take place, the tribes are in an uphill battle to have any meaningful input for this project,” Shepherd said.

Such consultation is more than a courtesy — it is a legal and ethical requirement. Multiple federal laws and statutes require agencies to engage with tribes on projects that affect their lands. Yet across the country, critical mineral projects are pressing ahead with minimal input from the Indigenous peoples whose lands and resources they affect. In Nevada, the Thacker Pass lithium mine moved forward in February without free, prior, and informed consent. In Minnesota, tribes report being sidelined as the Department of Defense funds mineral projects, while in Arizona, a transfer of federal lands to a copper mining company was just greenlit despite a lawsuit from the Apache Stronghold.

Canada also has moved to require meaningful Indigenous consultation. Although Canadian regulations generally don’t extend to operations abroad, British Columbia, where Graphite One is based, became the first jurisdiction in Canada to enshrine Indigenous rights under UNDRIP in 2019. In 2021, Canada’s Parliament followed, requiring federal laws to align with the U.N. declaration.

Amid these broader Indigenous rights debates, Alaska Native communities are voicing their concerns: Tribal leaders from around the Kigluaik Mountains gathered September 20 to oppose Graphite One. They discussed its “irreversible damage,” the potential violence against women that often accompanies the arrival of a large workforce in remote locations, and the generational impacts to the landscape. Tribal leaders also brought up the Trump administration’s executive order eliminating federal diversity and anti-discrimination policies, which they worry will undermine potential job opportunities at the mine for community members.

Although some Nome residents support the mine for its potential economic benefits, others are upset that the Bering Straits Native Corporation, a regional for-profit entity where many tribal members are enrolled as shareholders, invested $2 million in the project without a shareholder vote. “The tribe has the treaty responsibility and the right to government-to-government consultation,” said Nome Eskimo Community tribal member Addy Ahmasuk, who is Austin’s daughter. “But the corporation has taken up a lot of power as the owner of the subsurface rights.” When corporate interests exploit divisions within Native communities, she said, sovereignty debates can turn into conflicts over profit rather than a community’s well-being.

These divisions are compounded by accelerated reviews, which Austin Ahmasuk worries means environmental risks will be overlooked. “Even now, at the exploration stage, there’s a very noticeable change in the landscape,” he said, including the construction of roads, which he said will likely damage cultural sites. “You simply cannot avoid the archeological history. You essentially stumble across it everywhere,” he said.

On a recent afternoon, he tried to imagine what his hometown would look like once the mine was built. The company plans to build a facility almost as large as the town itself to store its ore. The public road the trucks would rumble down crosses numerous salmon streams, where families go to put away fish for the winter. “This mine needs so much infrastructure,” he said. “That’s a significant change to the community.” New sections of road risk disturbing wildlife habitat and may prevent access to hunting grounds and fishing sites generations have depended on. Without these lands, he said, families risk losing their main sources of food. Oversight of the mine, he added, will fall largely on the community “to even understand potential violations,” noting that state and federal regulators are rarely present in the region, and in his experience, provide only minimal monitoring. “People who really care about this area, we feel sort of hopeless,” he said.

Addy Ahmasuk, meanwhile, fears the toxic tailing ponds mining creates will pollute Imuruk Basin, which sustains the surrounding communities. Graphite One plans to mill and burn the ore to concentrate it prior to shipping, releasing graphite into the wind near a lagoon many families depend on for potable water, especially communities like Teller that lack running water. “Graphite dust makes water undrinkable,” she said. The ground naturally contains sulfides that, when disturbed by mining, will create a significant risk of acid drainage that will require long-term management. “Pretty much every mine that’s mining in sulfide material has some sort of water quality impact,” said Dave Chambers, founder of The Center for Science in Public Participation. The nonprofit provides technical support on mining and has been following the project closely.

He notes faster permitting has historically led to mining projects that go awry, pointing to the Rock Creek Mine, an open-pit gold mine near Nome that benefited from accelerated oversight. “Not only did the mine not even open because their engineering was so sloppy, but they killed a couple people,” Chambers said. “That’s a really good example of what happens when you try to grease the skids and get a project through as fast as possible.”

For Addy Ahmasuk, the lesson isn’t just to slow down, it’s to rethink what activism can look like. This land is central to her tribe’s creation myths. She’s launched a grassroots organization, Sacred Kigluait, aimed at restoring and sharing the stories that colonization and boarding schools sought to erase. In doing so, she hopes to protect more than just the land under threat from Graphite One — she’s fighting for the living traditions rooted in it. “The center point isn’t stopping a mine,” she said. “The center point is coming together to remember our creation stories and start telling them again.”

When permafrost thaw turns Arctic Alaska river red, toxicity levels rise, scientists find

By: Yereth Rosen, Alaska Beacon

When scientists Patrick Sullivan and Roman Dial were heading to a remote area in the Brooks Range in 2019 to map the spread of woody plants there, they were looking forward to seeing a celebrated river that author John McPhee described decades ago as having the “clearest, purest water I have ever seen flowing over rocks.”

What they found in the Salmon River, a waterway that flows through Northwest Alaska’s Kobuk Valley National Park, was much different than what McPhee described in his landmark 1976 Alaska book “Coming Into the Country.” The waters Sullivan and Dial found were reddish-orange and murky from loads of minerals flowing into them.

The Salmon River and its tributaries had become transformed into “rusting rivers,” a phenomenon caused by climate change in permafrost regions.

“The permafrost is thawing, and it’s essentially acid rock drainage that’s occurring. These sulfite minerals are being exposed to oxygen and water for the first time in thousands of years and it’s releasing acid which is leaching metals out of the rocks to the streams,” said Sullivan, who heads the Environment and Natural Resource Institute at the University of Alaska Anchorage.

The problem goes beyond aesthetics, according to further research by Sullivan, Dial, who is at Alaska Pacific University, and their colleagues.

The Salmon River, a designated wild and scenic river, and its tributaries are so tainted by acid-rock drainage that their concentration of metals is considered toxic to chronically exposed aquatic life, they found.

Water samples taken in the summers of 2022 and 2023 found that the river and almost all of its tributaries were carrying metals at levels above U.S. Environmental Protection Agency and state of Alaska standards, according to a recently published study by Sullivan and his colleagues. A variety of metals were showing up in amounts dangerous to aquatic life: iron, cadmium, aluminum, nickel, zinc and copper, their study found.

The “rusting rivers” pollution is similar to the kind of pollution that can happen from hardrock metals mining. But unlike the case with mining, it is happening in the absence of human development, and it is happening over diffuse spots, whereas a single point source at a mine that could potentially be controlled.

“This wild and scenic river in the heart of Kobuk Valley National Park, it’s about as protected as you can get and as remote as you can get. And it’s kind of falling apart,” Sullivan said.

The study, published in the journal Proceedings of the National Academy of Sciences, summarized the situation in its title: “Wild, scenic, and toxic.”

There are places around the Arctic where rust-red rivers have been that way for centuries, like Canada’s Arctic Red River, also known in the Gwich’in language as Tsiigehnjik, meaning “iron river.”

But for the Salmon River, the change was abrupt.

The Bush pilot who ferried Sullivan and Dial to the site in 2019, who described the river’s appearance as similar to sewage, said it had just happened that year.

The toxicity findings are potentially ominous for fish health.

The timing of the change suggests that thaw-induced acid rock drainage could be one of the many factors depressing western Alaska salmon runs, the study found.

Salmon runs have been disastrously low in the region for the past few years, sometimes precluding even traditional subsistence harvests that are relatively small in scale but hugely important to culture and food security.

At the very least, the timing is a coincidence, Sullivan said. “It’s identical to what you would expect if these degrading streams were impacting spawning success,” he said, pointing out that most of the chum salmon that returns to the Kotzebue Sound area do so at the ages of four of five years, after emerging from the spawning rivers and swimming around in the ocean.

There is too little evidence for now to definitely link the rust-tinted waters of the Salmon River to poor salmon runs, Sullivan said. That is largely because there is too little known about that river’s fish populations, though the name suggests that the river was important to salmon in the past, he said.

It appears to have been that way in the 1970s, when McPhee was there boating there, fishing, camping and collecting information for his book.

At that time, the water was so clear that the riverbed was “as distinct as if the water were not there,” McPhee wrote. Those clear waters chock-full of oval-shaped salmon swimming upstream to spawn, he wrote. “Looking over the side of the canoe is like staring down into a sky full of zeppelins,” he wrote.

The recent proliferation of rusting rivers is not limited to Alaska and other parts of the Arctic. There are affected high-altitude areas that have permafrost, glaciers or both, including Switzerland and neighboring parts of the AlpsPeru and parts of Colorado.

In Alaska, the rusting rivers phenomenon is more pronounced in the western part of the North Slope than in the eastern part, Sullivan and Dial have found. Their past studies linked the vegetation changes in the northwest to more pronounced warming on the Chukchi Sea side of Alaska’s Arctic than on the Beaufort Sea. That spread of woody plants is detrimental to tundra caribou that eat lichen and moss, and could help explain the decline in the Western Arctic caribou herd, which has a habitat that is changing more quickly than that of the Porcupine caribou herd on the eastern North Slope, they found.

After Sullivan and Dial encountered multiple rusting rivers during their plant studies, they felt compelled to alert fellow Alaskans about the situation.

They penned a 2022 column for the Anchorage Daily News. And they embarked on their further studies, which wound up generating a small National Science Foundation grant, creating partnerships with scientists at other universities who are experts in biochemistry and, ultimately, the newly published study on toxicity.

But before then, when they were expecting to see the same conditions that McPhee did in the 1970s, Sullivan packed a fishing rod with the gear he took on the trip to the Salmon River.

His attempts to fish in the murky, opaque water proved futile, however. “I think I tried for, like, five minutes and then I quickly realized that I was wasting my time,” he said.

That experience suggests that there might be further ecological impacts of the cloudy, rusted waters, he said.

“I think it would be very hard, for instance, for a bear to fish for a salmon just because of the turbidity. Raptors would have a really hard time catching a fish if they were fishing there,” he said, citing the suspended solids that make the water opaque.

For now, Sullivan and other scientists are using satellite imagery to spot other rivers and streams that might be similarly affected. The imagery is useful not just for spotting acid-tinted streams but the point sources in the tundra, he said.

It would be helpful to have more research on the region’s fish to explore whether they are carrying metals in their bodies, he said. Another topic of study could be the response of chum salmon in the region, as the species does show the some ability to shift habitats, he said.

Yet to be determined, Sullivan said, is how long this rusting river situation will last.

“It’s possible that this will kind of run its course over some period of time. And once the unweathered sulfite minerals have been oxidized, then it’s likely that the stream will turn back to clear again,” he said. “But we have no idea when that process might reach its conclusion and how many new acid seeps might develop.”
