Scientists confirm climate change is making destructive landslides more frequent across Alaska — especially in Southeast

Listen to this story:

Landslides have killed at least a dozen people in Southeast in recent years. 

That prompted Aaron Jacobs, a hydrologist at the National Weather Service in Juneau, and his colleague to answer a major question people in the region have been asking: “Are we seeing more landslides across Southeast Alaska?”

A couple of years ago, scientists weren’t sure. Now, Jacobs says the answer is yes.

According to the study, published in the journal Landslides in November, news outlets reported 281 destructive landslides between 1883 and 2025 in Alaska. Jacobs said they decided to use news reports as the data source because if a landslide affected people or infrastructure, it probably made the news.

They found the number of reported landslides started to increase in the 1980s and has skyrocketed in recent decades. 

Fewer than 10 damaging landslides were reported per decade before 1980. From the 1980s to the 2010s, they found a 295% increase in impactful landslides across the state. In the 2010s, 84 damaging landslides were reported. In just the first half of the 2020s, 76 landslides have made the news.

“A big thing that stuck out was the precipitation-driven or triggering events that were increasing within the last 20 years,” Jacobs said.

The four fatal landslides that hit Southeast in recent years — Sitka in 2015, Haines in 2020, Wrangell in 2023 and Ketchikan in 2024 — were all triggered by heavy rain or rapid snowmelt.

In the paper, the scientists drew a connection between rising average annual air temperatures — between 1.2 and 3.4 degrees Celsius — and a 3% to 27% increase in precipitation across Alaska over the past half-century. 

“It’s all connected,” Jacobs said. 

It’s a result of climate change. As the globe heats up, more intense atmospheric rivers are slamming Southeast because warmer air can hold more moisture. These downpours cause steep slopes to crumble. 

Climate change is also expected to raise the frequency and intensity of storms that dump rain on top of snow. When the rain melts the snow, it rapidly saturates hillsides and can make landslides more likely. Additional research published Wednesday by Jacobs and others found that this phenomenon triggered the 2023 Wrangell landslide.

Earlier this month, Jacobs and his colleagues posted a manuscript of a scientific paper addressing these rain-on-snow events that hasn’t been peer-reviewed yet. They used a high-precision weather forecasting model to assess atmospheric rivers in Southeast within the last handful of decades and project how they could change in the near future.

The researchers found that rain-on-snow events coincided with 8% of landslides assessed between 1981 and 2019, including some that were large and widespread. They predict that rain-on-snow events will happen more often and involve an increase in extreme rainfall and snowmelt between 2031 and 2060 as the atmosphere continues to heat up.

How people use the land also plays a role in where landslides occur and how they affect people. On Prince of Wales Island, scientists have mapped nearly 800 landslides. The island is crisscrossed by hundreds of miles of logging roads. 

“The writing is on the mountain,” said Quinn Aboudara, natural resources manager for the Shaan Seet tribal corporation in Craig. 

He said he’s noticed that landslides are more prevalent in logged patches and where roads cut across steep slopes. When he was growing up in Port St. Nicholas Bay, he said landslides weren’t as frequent and more snow fell in the winter. In recent years, it mostly rains. 

“Now we treat the rainy seasons as landslide season,” he said. 

Shaan Seet is piecing together a road and culvert inventory to identify problematic areas. During a deluge, Aboudara said some old culverts meant to funnel water under roads clog or just aren’t big enough to handle the runoff. He said that causes water pressure to build up in the hillside and can lead to landslides. 

“We’re looking to replace those with actual bridge works instead of culverts,” he said. 

At the Sitka Sound Science Center, Luka Silva is working on other measures to reduce risk. He manages the Ḵutí Geohazards Project, which works with Southeast communities to address gaps in landslide science and public safety. 

“Because no one wants to lose their neighbor or their home or their friends or loved ones in a landslide, and we have steps that we can take to make that less of a possibility,” Silva said. 

The center developed an early warning system for Sitka that Silva said other communities are using as a model. Scientists are studying soil thresholds to someday forecast landslides. Many communities are working on or already have landslide hazard maps. 

But some municipalities have struggled to take action. After residents in Juneau pushed back against updated landslide hazard maps, the Juneau Assembly declined to adopt them and rolled back development restrictions in landslide paths. Nearly identical stories played out in Sitka and Haines. It’s because homeowners don’t want to see their property values tank and insurance premiums rise. 

Silva urges people to keep the bigger picture in sight.

“We know what we know about how our landscape is going to change even further, and how our landslides are going to be more and more impactful and frequent,” he said. “What are we going to do about that? And what are we going to do to make people safer?”

Republican Sens. Murkowski and Tillis call for Noem to resign

WASHINGTON — Sen. Lisa Murkowski said Secretary of Homeland Security Kristi Noem should be held accountable over a fierce immigration crackdown that has killed two citizens in Minneapolis and that she should resign.

“She has — through her words, and I think in her actions — she’s taken a direction that has not been helpful to the situation, and I don’t think that it helps the country,” Murkowski told reporters.

She said Noem has an obligation to maintain control of what the agencies in her jurisdiction are doing. Instead, Murkowski said, Noem has inflamed tensions. She noted that almost immediately after Border Patrol agents shot and killed nurse Alex Pretti, Noem claimed, without evidence, that Pretti was a “domestic terrorist.”

Murkowski spoke to reporters on her way to a Senate vote as lawmakers returned to the Capitol from a week away. She called it a good sign that the administration has removed top Border Patrol official Gregory Bovino from Minneapolis. But, she said, accountability rests with Noem.

Reporters pressed her on whether Noem should resign.

“I voted for her,” Murkowski said, referring to Noem’s Senate confirmation. “I think the President needs to look at who he has in place as a secretary of Homeland Security. I would not support her again, and I think it probably is time for her to step down.”

Murkowski was among the first Republicans in Congress to openly criticize the tactics of the immigration enforcement operation after agents killed Pretti. The group of GOP critics remains small.

But minutes before Murkowski spoke, Sen. Thom Tillis, R-N.C., also castigated Noem. He said the enforcement operations need to focus on the serious criminals President Trump promised to target and not pursue nonviolent people.

“I think that what she’s done in Minnesota should be disqualifying. She should be out of a job,” Tillis said of Noem. “And I mean, really, it’s just amateurish. It’s terrible. It’s making the president look bad on policies that he won on.”

Tillis is retiring from the Senate after his term ends in a year. He’s become one of the more outspoken Republicans in Congress when it comes to criticizing and voting against the Trump administration.

Unlike Murkowski and Tillis, Sen. Dan Sullivan, R-Alaska, didn’t issue a social statement or a press release this weekend to condemn Pretti’s death or call for reform.

His office provided a statement to reporters on request. Sen. Sullivan “strongly supports our law enforcement and their ability to do their jobs,” it says, while calling any loss of life tragic. It also says he hopes that “the temperature in Minnesota on both sides can be lowered.”

On his way to the Senate chamber to vote Tuesday, Sullivan held his phone to his ear as he walked through a crowd of reporters, fending off approaches.

Union contract negotiations spark student outrage in support of Juneau teachers

Listen here:

Juneau high school students are speaking out about how unresolved contract negotiations are affecting them in the classroom. 

It’s been nearly a year since contract negotiations officially began between the Juneau School District and its teachers’ union. During negotiations, they reached an impasse and the district declared it would enter arbitration with Juneau Education Association. But they haven’t yet reached a new agreement. The district also hasn’t reached an agreement with its support staff union.

Seventeen-year-old Zoe Lessard is a senior at Juneau-Douglas High School: Yadaa.at Kalé. She sits on the Juneau School District Board of Education as a student representative. At meetings, she typically gives updates on school dances and sports.

But during a meeting in October, she got up from where she normally sits for board meetings and sat at the testifier seat to speak as a student and not a representative.

“These people were and are my advocates, my friends, my support, and some of them, my family,” she said. “My teachers have pushed me to be better and go into my future with confidence. Please allow them to continue to do this.”

Lessard spoke after more than an hour of comments from teachers and community members sharing their experience about working without a new contract. Some spoke about taking multiple jobs to make ends meet. Others said they were overwhelmed with the workload. 

Outside of the board setting, Lessard is continuing to speak out. She wants to send an even stronger message. So she turned to the high school’s student government last week with a drafted message.

“I cannot say what I really want to say at school board meetings, and I thought it would be a powerful statement if it was approved by the whole student council,” she said.

The high school’s governing body of 42 students unanimously approved the statement. Lessard is part of the student government because of her school board role. 

The written statement speaks to the need to have contracts that adequately pay teachers. 

“We, as the Juneau-Douglas High School: Yadaa.at Kalé Student Government, are completely appalled at the Superintendent and School Boards (sic) lack of action about this matter,” part of the statement reads. “We do not support your decision to leave teachers and support staff with insufficient contracts.”

Lessard has some personal insight into teachers’ lives; her dad is a teacher. But, she said, students in general notice and see the impact not having a new contract has on teachers.

“If they are stressed, if their needs aren’t getting met, if they need to work one or two other jobs, we notice, and we notice because they aren’t able to focus on teaching as much as they would like to, which is by no means their fault,“ she said.

The statement also brings up teacher vacancies. Based on reports from early January, the Juneau School District has more than 40 open teaching and staff positions. Vacancies and employees not opting into the district’s health insurance plan amounts to $8.5 million dollars in unused funding, according to board documents.

Bella Reyes-Boyer is the student body president at the high school. Her mom is a veteran teacher and now the school’s librarian. Last year, Reyes-Boyer volunteered at an elementary school and said she saw the effect teacher vacancies have on students.

“I really got to see firsthand how important having those paraeducators and, like, teachers who are actually able to accommodate each student individually, and how important that really is.” She said. “It was really apparent that there is a lack of, like, specialized teachers for certain students.”

Lessard said many students don’t know much about the contract negotiations, so she’s trying to educate her peers. She wants them to speak to the board in support of teachers.

“I would hope people come and testify for their teachers and support staff at the next school board meeting, that they tell the school board how much the teachers and the staff in the schools matter to them and how that’s what they need to be investing in for everybody’s future,” she said.

Juneau Education Support Staff, the union representing employees like paraeducators and custodians, had its latest negotiation meeting on Jan. 26. JEA met with the district last month, according to JEA negotiation support team co-chair Kelley Harvey. JEA and the district have an arbitration hearing scheduled April 27 and 28. As of Tuesday, JESS does not have any additional meetings scheduled with the district.

The school board is holding several budget-specific meetings in the coming weeks, including a budget work session on Tuesday evening and a budget public forum on Feb. 5.

Newscast – Tuesday, Jan. 27, 2026

In this newscast:

  • The Juneau Assembly has stalled on deciding whether to disempower the Eaglecrest Ski Area’s board of directors until March.
  • Students are speaking out about how unresolved union negotiations are affecting them in the classroom.
  • Students in Skagway are calling on their school district to adopt a policy that would let them take part in subsistence activities without it potentially counting against them.
  • With almost 700 participants, Juneau’s annual board game convention sold out for a second year.

Skagway students are asking for time off school to participate in subsistence activities

The federal government says 98% of rural Alaskans catch, hunt or gather at least some of their food. And much of that happens during the school year.

Now, students in Skagway are calling on their school district to adopt a policy that would let them take part in those activities — without it potentially counting against them.

The push originated with Ryder Calver, who is the treasurer of the Skagway student council. Calver said he’s gone moose hunting almost every year since he was six years old. But in his experience, taking part in an annual moose hunt eats up most of his allotted absences in one go – leaving little room for other absences later on.

“I’m gone for around 10 days each time, and the school only allows you to miss 15 days total per semester, whether that is a trip, you’re sick, excused or unexcused,” Calver said. “I got the idea to add a buffer.”

So this fall, Calver teamed up with Student Council Senior Parliamentarian Sam Munson to write a resolution they hope will push the school board in that direction.

Right now, students can be penalized after their fifteenth excused absence – unless they get a waiver from the superintendent or school board. The resolution makes a case for allowing students to take up to 7 “subsistence days” per semester, which wouldn’t count toward the 15 day limit.

The board’s policy committee took up the issue during a recent meeting. Munson, Calver and Student Council President Lina Hischer spoke, saying the policy should specifically provide flexibility around subsistence activities.

The fact that the current policy doesn’t do that “negatively affects kids who do subsistence hunt or gather,” Hischer said. “We want to make it more even, or equal.”

During the meeting, Skagway School District Superintendent Josh Coughran said the policy could be updated to mention subsistence activities – and to allow students to proactively request days off for a moose hunt or other trip that wouldn’t count against their attendance record.

In that case, he said subsistence days could be treated like travel days for sports or debates – which don’t count as absences.

“We know they’re not in school, but it’s on a school-sanctioned event. And so this would be the school sanctioning subsistence activities and not counting it against families,” Coughran said.

The board is set to discuss the issue at a meeting this week.

Coughran said in an email on Monday afternoon that it’s still “early days” for the idea. If the board decides to move forward with the proposal, it would go back to the policy subcommittee and then return to the full board for consideration.

Juneau Assembly stalls on whether to disempower Eaglecrest Ski Area’s board

The Juneau Assembly has stalled on deciding whether to disempower the Eaglecrest Ski Area’s board of directors until a joint meeting in March. 

Earlier this month, Mayor Beth Weldon proposed an ordinance to reduce the status of the city-owned ski area’s board from an empowered board to an advisory board. She cited the recent leadership turnover at the mountain and ongoing financial challenges.

At a committee of the whole meeting Monday night, Weldon further explained her reasoning for the proposed ordinance to the Juneau Assembly and the roughly 20 members of the public in the audience. 

“I’m literally trying to save Eaglecrest, and I think with the empowered board making the decisions, I don’t see the status quo changing,” she said.

Right now, as an empowered board, Eaglecrest has its own set of laws, rules and responsibilities. But, if it became an advisory board, members could only make recommendations to the Assembly. It would lose the authority to establish policies or make decisions without Assembly approval. 

At the meeting, Weldon argued the ski area needs more oversight, given the high amount of funding the city has funneled toward it in recent years, specifically on a new gondola project.

“If we are investing large amounts of money on things such as the chair lifts or maybe even the gondola, we want to have more of a say in how that money is spent, and currently, we don’t,” she said. 

In the coming years, the ski area is slated to run into a multimillion-dollar deficit. The deficit is a part of a plan to repair some broken and aging infrastructure while boosting pay to employees and preparing to operate year-round. 

Its expansion into summer operations relies heavily on the success of the gondola, which the ski area hopes to get up and running by the summer of 2028. However, many city leaders are worried the timeline — and cost — of the project will run far over what the board projected. 

The Assembly agreed to hold off on any decision-making until it holds a joint meeting with the Eaglecrest board on March 4. Assembly member and Eaglecrest Ski Area board liaison Neil Steininger said he thinks that’s the best option. 

“I think we owe it to everybody in the community to have a joint meeting with the Eaglecrest board to actually hash this out,” he said. 

The Assembly will then vote on whether to move the ordinance forward during a committee meeting on March 16.
