Energy, crime and homeschool allotments: The big bills to watch as time runs out in Alaska’s legislative session


JUNEAU — With just days left in the Alaska Legislature’s regular session, major policy measures are unresolved related to energy, crime, homeschool allotments and elections.

In recent years, the budget has been the biggest source of contention and debate between legislators and Gov. Mike Dunleavy. This year, the budget has largely advanced smoothly. However, the size of this year’s Permanent Fund dividend has not been reconciled. Across the political spectrum, legislators expect it will be close to the Senate’s approved figure of almost $1,600 — lower than the nearly $2,300 figure sought earlier in the session by the House.

Senate President Gary Stevens, R-Kodiak, said Saturday that crime and energy bills are the “most crucial” measures being considered this year.

Legislators say that a multipart elections bill is the least likely of the big policy items to pass. It combines a proposal to clean up the state’s voter rolls with election provisions typically supported by progressives, like same-day voter registration.

Fairbanks Democratic Sen. Scott Kawasaki, the chief sponsor of the elections measure, acknowledged that energy, education and the budget are the highest priorities for the Legislature.

”But you can’t forgo the other issues that are part of this Legislature, like elections,” he said. “These are other things that have to pass.”

The House spent more than seven hours Saturday debating a doomed bill to restrict how transgender girls participate in school sport teams. Meanwhile, the Senate Finance Committee continued discussing and amending some of the Legislature’s biggest policy priorities.

There have been frequent breaks so legislators and the governor’s staff can meet behind closed doors to negotiate. But House members were kept largely occupied by the floor debate, halting their work on some legislation they have sought to prioritize.

The Alaska Legislature’s regular session must end by midnight on Wednesday, May 15.

Energy and transmission

Addressing a looming shortfall of Cook Inlet natural gas has been a key priority this year for Dunleavy and many in the Legislature.

Several measures have been heard to reduce royalties on oil and gas production, which are intended to incentivize new gas production. Members of Senate leadership have raised concerns that forgoing state royalty revenue won’t necessarily see more gas produced. Stevens said there’s simply not enough time left to consider and approve those bills.

“I just don’t see how we can come to a conclusion on that because we just don’t know the implications,” he said Saturday.

Asked if he thought royalty relief was off the table this year, Sutton Republican Rep. George Rauscher said, “Not at all.” He said House Bill 223 could be considered Saturday or Sunday on the House floor as discussions continue with the Senate.

The bill was initially scheduled for a floor hearing Saturday morning, but its hearing was delayed to allow time for the hours-long debate on transgender policy.

“We’re still negotiating but I’m stuck on the floor. Otherwise, I would have been able to get a lot farther today,” Rauscher said Saturday.

Green bank bills have advanced to a final vote on the House and Senate floor. The measures proposed by Dunleavy would allow the Alaska Housing Finance Corp. to offer loans for renewable energy projects. More than 80% of the Railbelt’s power comes from natural gas. A green bank bill has been supported as a way to diversify the Railbelt’s sources of energy, and is expected to pass into law this year.

Measures are also being heard by the House and Senate finance committees to modernize the Railbelt electric grid. The proposal for an integrated transmission system has divided the Railbelt utilities. Several prior attempts to form a transmission organization have fallen short over the past 50 years.

Chugach Electric Association — the state’s largest electric utility — has opposed key elements of the plan, leading legislators to coalesce around a more limited version of the proposal. The transmission organization would not have planning authority or management of the utilities’ assets. Sen. Cathy Giessel, R-Anchorage, said Saturday that would be a “shell” of the proposed transmission organization she helped author.

The measure originally proposed by Dunleavy would also have exempted renewable power producers from local property and sales taxes. On Saturday, legislators said that provision is still being negotiated between lawmakers and the governor.

Another key measure is House Bill 50. It would develop a statutory framework so the state could lease depleted gas reservoirs to store carbon dioxide deep underground. Once pitched as a revenue-raising tool for the state, carbon sequestration has now been supported as a way to attract oil and gas investment.

A provision added to HB 50 would allow the Alaska Industrial Development and Export Authority, or AIDEA, to issue loans to producers based on their gas reserves. Those loans are intended to assist BlueCrest, an Alaska-based producer, that needs $400 million to buy a platform to produce gas from the Cosmopolitan Unit in Cook Inlet.

The bill has a provision intended to prevent oil companies from deducting carbon capture and storage expenses from their state oil production taxes. But producers could still deduct costs for enhanced oil recovery.

Officials at the Department of Natural Resources have said enhanced oil recovery is a currently allowable tax deduction, and part of the oil industry’s normal operations on the North Slope. Sen. Bill Wielechowski, D-Anchorage, has argued that allowing deductions for enhanced oil recovery could potentially “blow an enormous hole” in the state budget.

A contentious provision to raise taxes on Hilcorp by more than $100 million per year was removed from the bill Wednesday after a fierce lobbying campaign.

The carbon storage bill was in the Senate Finance Committee as of Saturday evening. There have been concerns expressed in public testimony that carbon sequestration is expensive and largely unproven. But the bill has been a key priority for Dunleavy and many in the Legislature, and is expected to pass this year.

Crime bill

An omnibus crime package in the Senate combines proposals from a handful of House and Senate bills. The package has been crafted to get enough support in both legislative chambers, and is broadly expected to pass this year.

“As we move into an election here, people want to take a stance on crime. It’s such a powerful thing for people to run on,” Stevens said.

House Bill 66 contains provisions for tougher sentences for stalking; enhanced penalties for committing domestic violence and sex assault offenses in the presence of a child; renaming child pornography as child sex abuse material in state law; and the imposition of “some additional jail time” for repeated violations of conditions of release from prison.

Homer Republican Rep. Sarah Vance, chair of the House Judiciary Committee, said “it is very, very important” to pass a crime bill this session.

”Addressing crime and protection for victims is just as important as addressing energy and education. I believe we can do all at the same time,” said Vance.

”Do I love everything? No. But I can live with most of it,” Anchorage Republican Rep. Craig Johnson said Saturday.

Alaska reported its highest-ever rate of fatal opioid overdoses in 2023. As a response to the state’s fentanyl crisis, a contentious set of provisions would impose longer sentences on drug offenses.

Sandy Snodgrass, whose son Bruce Snodgrass died from a fentanyl overdose in 2021, spoke in support of those provisions. She said Alaska’s leaders need to respond “to the scourge of fentanyl and illicit drug poisonings in our state.”

The ACLU of Alaska opposes several key elements in the bill. Michael Garvey, advocacy director of the civil rights law firm, said longer sentences would not act as a deterrent.

“However, they often have the opposite effect of incarcerating people with substance use disorders and deterring people from calling for help,” Garvey said Thursday.

Under HB 66, crime victims and witnesses would no longer need to present in-person at grand juries. That change would allow law enforcement officials to summarize a victim’s testimony or to show a video of that testimony at grand jury proceedings. Victims’ rights groups have said that could help avoid retraumatizing crime victims, particularly in domestic violence and sexual abuse cases.

The federal government and 33 states allow “hearsay” evidence to be presented to grand juries to secure an indictment, which is constitutionally required in Alaska for a felony charge to proceed to court. The change would apply not just to domestic violence and sexual abuse, but to all felony offenses.

Civil liberties groups have raised concerns that using second- and third-hand evidence at grand juries could deny Alaskans long-held protections against unfounded charges.

Susan Orlansky, a private attorney who often volunteers with the ACLU of Alaska, said she was concerned because grand jurors could not evaluate the credibility of witnesses or ask follow-up questions. Under the bill, the law enforcement officer presenting to the grand jury may not have interviewed the victim or investigated the case.

”By allowing second- and third-hand hearsay, the bill authorizes testimony that’s no more reliable than the last statement in a game of telephone,” Orlansky said.

Sen. Jesse Kiehl, D-Juneau, said Saturday that he’s sensitive to the concerns of victims’ rights groups, but he is also trying to craft an amendment to narrow what hearsay evidence can be presented to grand juries.

Another key provision in the bill would extend the period certain people can be involuntarily committed. That comes after an Anchorage woman, Angela Harris, was stabbed in the back two years ago in the Loussac Library by a man who had been deemed unfit to stand trial.

Supporters say involuntary commitment reforms could help protect Alaskans. But the ACLU of Alaska has raised constitutional concerns about the impacts of extending involuntary commitment from a maximum period of six months to two years. Sen. David Wilson, R-Wasilla, said he was concerned that the long-struggling Alaska Psychiatric Institute could also be overwhelmed with new patients.

Homeschool and education

Competing bills in the House and Senate would instruct the Alaska board of education to draft new regulations governing Alaska’s correspondence programs, after an Anchorage Superior Court judge ruled last month that two state statutes violated the state constitution by allowing public funds designated for the program to be used at private and religious schools.

But the bills — and the urgency that some lawmakers see in passing legislation to shore up the schools that serve nearly 23,000 homeschooled Alaskans — could be used as a vehicle to add other education provisions, including a permanent increase to state spending on education long sought by educators.

The correspondence school statutes, conceived by Dunleavy when he was a state senator, were enacted in 2014, allowing for a growing practice of families using correspondence allotments of up to $4,500 per student per year to be used to pay tuition at private schools.

The decision by Judge Adolf Zeman, which prohibited the practice but kept correspondence programs in place, was paused through June. It was appealed by the Dunleavy administration to the state Supreme Court, which has proposed an expedited hearing schedule.

House Bill 400, authored by Rep. Justin Ruffridge, a Soldotna Republican, would create a temporary solution, instructing the state board — whose members are appointed by Dunleavy — to put in place regulations that will expire in 2025, allowing lawmakers to work on a permanent solution when they return to Juneau next year that takes into account the supreme court decision.

At Dunleavy’s urging, the bill would also keep on the books the statutes that Zeman found violated the state constitution, meaning they could be reinstated if the Alaska Supreme Court overturns Zeman’s decision.

The House Finance Committee held a hearing on the bill that lasted late into the evening on Friday. During the hearing, some minority members raised concerns about whether the state board of education could be trusted to enact regulations that followed the constitution.

“They’re going to philosophically follow what the attorney general tells them to follow,” said Rep. Andy Josephson, an Anchorage Democrat. Attorney General Treg Taylor has used correspondence allotments to pay tuition at private Christian schools.

Senate Bill 266, authored by Sen. Löki Tobin, an Anchorage Democrat, would instruct the state board to author permanent regulations — with more defined guardrails on how the correspondence allotments can be used, including a limit on the amount of funds that can be kept from year to year, and a limit on the amount of funds that can be used to pay for private music, arts and physical education classes.

Stevens, a Kodiak Republican, said he trusted that the board would enact constitutional regulations, even if lawmakers failed to pass a bill instructing them to do so before the end of the session.

“In the end, if we can’t get a bill through — I’d prefer it if we could, but if we can’t — then I think the governor and the administration and the department has the wherewithal to write the rules,” said Stevens.

The Senate bill must be heard by the Finance Committee before it can head to a floor vote. It has yet to be scheduled for a committee hearing.

“As they often say, they are not a rubber stamp, so they’re going to do their due diligence,” Tobin said of the coming hearing in the Finance Committee, adding that she expected the House proposal could pass before the Senate finishes considering its competing proposal.

Despite Dunleavy’s indication that he wanted to keep the struck-down statutes on the books, Tobin said she wanted to see them amended in legislation that lawmakers consider this year.

“My approach is to pass legislation that will create stability and certainty,” she said.

In Friday’s House Finance Committee hearing, Rep. Alyse Galvin, an Anchorage independent, proposed an amendment that would have permanently increased Alaska’s education funding formula. That amendment was tabled in a narrow 6-5 vote. The committee ended its work for the day at 8 p.m. without passing the bill, leaving open the possibility of further changes when the House Finance Committee reconvenes.

“To me, there’s nothing more important than having predictable, adequate, stable funding,” said Galvin. “This is just a lift-all-boats amendment.”

Lawmakers earlier this year agreed to permanently increase the Base Student Allocation from $5,960 to $6,640, amounting to an increase of roughly $175 million per year. But Dunleavy vetoed that bill and lawmakers failed by a single vote to override his veto.

The current year’s budget already has an equivalent funding boost, but the funding was added on a one-time basis, meaning it would not be included in next year’s budget without additional action by lawmakers, and schools are limited in how they can use the funds.

Supporters of the permanent boost have said it will aid all public school students in Alaska, including correspondence and charter students, who have been championed by Dunleavy.

Lawmakers opposed to the move, including many House Republicans, have said they opposed it because Dunleavy has said he will veto an increase to the Base Student Allocation unless his priorities are satisfied.

Dunleavy said earlier this year that he is seeking to empower the state board of education to approve new charter schools — a power currently given only to locally elected school boards. Leaders of the bipartisan Senate majority have said they’re opposed to the proposal.

Tobin said that without specific guidance from Dunleavy on whether he would support a permanent BSA increase, the bipartisan Senate majority would be unlikely to pursue adding a funding boost to a bill meant to stabilize correspondence schools.

“I do not see the bandwidth of my caucus to go back through the negotiation process just to have a similar outcome as what happened (on the vetoed bill),” said Tobin.

“It is a little difficult to know what we could get across the finish line at this point in time. So it feels like it’s a bit of a shot in the dark.”

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.

Advertisement

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.

Advertisement

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.

Opinion: The cost of waiting on Alaska LNG is already showing up

As former mayors of Anchorage, we each had the responsibility of leading Alaska’s largest city through moments of challenge and opportunity. While our administrations differed in time and approach, one priority remained constant: ensuring that Anchorage and Alaska have access to reliable, affordable energy.

Energy keeps our homes warm through long winters, powers our schools and hospitals, and fuels the businesses that employ our neighbors. It literally fuels every aspect of our economy and our quality of life. When energy becomes uncertain or unaffordable, the consequences are felt immediately by families, employers and communities across the state.

Today, Alaska faces a generational energy challenge. Cook Inlet natural gas production has been declining for decades. Like the frog in a pot on the stove, the problem around us has slowly grown but is about to reach a raging boil. Declining supplies of inexpensive Cook Inlet gas, rising demand and a lack of long-term certainty jeopardize the stability we rely on. Without action — right now — we will lose control over energy costs and availability.

We have faced moments like this before. During his tenure as mayor, Dan Sullivan recognized early the urgency created by declining Cook Inlet gas production. He convened an Energy Task Force that brought together industry leaders, policymakers and stakeholders to confront the issue directly. That work helped lay the foundation for the Cook Inlet Recovery Act, which the Legislature passed quickly to spur new investment and extend the life of the basin. It showed what is possible when Alaska acts with focus and urgency. It also showed the legislature can move fast when aligned on policy.

This is not a new conversation. For years, studies commissioned by both the Alaska Legislature and multiple administrations have identified the need to modernize Alaska’s tax structure and energy policies to remain competitive for large-scale investment and infrastructure projects. Again and again, those reviews reached the same conclusion: If Alaska wants to attract and keep transformational projects, the state must provide a stable, competitive framework that reflects the realities of modern energy development.

The Alaska LNG project is the only viable path to meet that need. It would deliver a stable, long-term supply of natural gas to Southcentral Alaska, helping ensure that homes, schools and businesses have dependable energy at predictable prices. It would also create jobs, strengthen the economy and generate revenue that supports essential public services.

For Anchorage and the entire Southcentral region, the stakes could not be higher. As the economic center of the state, Anchorage depends on dependable energy to sustain growth and opportunity. Utilities, employers and families all need certainty to plan ahead.

If the Legislature fails to pass meaningful property tax reform for Alaska LNG, this opportunity will slip away like other projects have done. Alaska’s property tax system was not designed for a megaproject like Alaska LNG. Because of that, tax reform legislation was introduced in March that will lower our energy bills and speed the delivery of natural gas from the North Slope. Our legislators must act quickly on a targeted solution and avoid making changes that raise energy costs or slow this project. Otherwise, Anchorage and all Southcentral Alaska will be forced to rely on imported gas for decades.

That outcome exposes us to higher and more volatile costs, shrinks our economy, prevents job growth and sends billions of dollars out of state.

Every day of delay increases that risk. As our electric and gas bills made clear this winter, costs are already rising. Without fast action, consumers should be prepared for increases of 30% to 40% or more. Our state will become an even harder place to start a family or a business.

A project of this scale requires careful consideration and responsible decision-making. But waiting carries its own consequences. The longer Alaska delays, the fewer options remain and the more expensive those options become.

As former mayors of Anchorage, we each had unique approaches to problem-solving. But now we speak with one voice: State leaders and legislators must act with urgency and purpose to enact tax changes that propel this project and unlock the revenue, economic, energy security and other benefits from our North Slope natural gas. Decisions now will shape the state’s economic future for generations.
