The treacherous ice of northern Alaska claimed another life last November when Elmer Brown, 45, plunged into frigid waters while caribou hunting.
Following two friends on his four-wheeler, the ice gave way, leading to the drowning of one companion and Brown's subsequent death from hypothermia, leaving behind five children. His brother, Jimmy Brown, lamented, "He was always helping other people and sharing his catch with the elders. It's been tough, not seeing him. I keep expecting him to walk in and tell me about his day."
This tragic incident underscores a growing crisis across the Northern Hemisphere, where warming winters are rendering ice conditions increasingly unpredictable and perilous. The friends had been hunting under pressure to make the most of shorter and less reliable seasons, a challenge exacerbated by climate change. The Brown family has experienced such loss before; their father drowned in 1999 during a seal hunt.
Thousands have perished on ice in recent decades as conditions become thinner and less reliable for those who depend on frozen lakes, rivers, and coastal waters for sustenance and recreation. March and April are particularly dangerous months as winter conditions recede. Alaska faces especially acute risks, with the erratic ice season disrupting Indigenous hunting traditions and compelling individuals to take greater chances. While some communities now utilise satellite imagery and social media to monitor ice, these technological aids cannot fully compensate for the lost predictability that generations once relied upon.
A 2020 study examined more than 4,000 winter drownings across 10 countries, including Canada, the U.S., Russia and Japan, over a 26-year period ending in 2017. It found drowning rates surged fivefold when winter temperatures rose to just below freezing. Deaths peaked in March and April, when reduced snow cover allows sunlight to penetrate the ice, melting it from within in invisible ways, said Sapna Sharma, a biology professor at York University and the study’s author.
“It’s only a matter of three to five days where you can go from safe ice conditions to totally unsafe,” she said.
A 2013 study published in the Journal of Public Health found in Alaska alone, some 450 people fell through the ice between 1990 and 2010, with at least 112 deaths. Most accidents occurred in November and March — transition months when ice is forming or melting — while people were traveling or hunting. Snowmobiles were involved in half the cases. The researchers encouraged more awareness of conditions and better safety training and equipment.
Elsewhere, ice safety approaches vary. Researchers say Minnesota and Wisconsin have seen ice‑related deaths drop as officials reduced speed limits and expanded safety courses. Germany and Italy have few drownings thanks to strict ice regulations that people follow. Estonia and Latvia have higher drowning rates despite similar temperatures, as ice fishing is embedded in culture and alcohol consumption during winter activities is common. In Canada, which has millions of lakes scattered across a vast landscape, enforcement is nearly impossible.
The Brown brothers’ hometown of Kotzebue, a predominantly Inupiaq community of 3,000, is perched on a narrow spit of land surrounded almost entirely by water. During winter, frozen waterways are the only way in and out, besides planes. There, average fall temperatures have warmed by 10 degrees Fahrenheit (6 degrees Celsius) over the last 50 years.
To the south, in the Bering Sea — where many western Alaska communities rely on coastal ice for travel and hunting — ice season is more than 40 days shorter on average than it was in the 1970s.
What was once a predictable early fall freeze-up has become later and more erratic: freezing, then breaking up, sometimes crumbling to open water for weeks before freezing again.
This unpredictability is eroding generations of ice safety knowledge. In a state where more than 80% of communities are not connected to the road system, extended transition periods — too slushy for boats, too unstable for snowmachines — can leave villages with few options to hunt or travel.
Earlier sea ice breakup has shortened Kotzebue’s spring seal-hunting season by 26 days compared to a decade ago, research shows.
“Each winter, it gets more and more dangerous to be out on the ice,” said Roswell Schaeffer, 78, one of Kotzebue’s few Inupiaq who still hunts seals at the treacherous ice edge.
Three years ago, Schaeffer's 50-year-old son fell through the ice while traveling by snowmobile in spring. He sustained a serious brain injury and later died by suicide.
Schaeffer hopes to teach his great-grandson to hunt seals, but worries the rising danger will cause the tradition to fade.
“Our native food is really key in terms of how we survive the Arctic,” Schaeffer said. “The ice is changing too much, and it’s not going to slow down.”
The climate-driven changes are creating difficult choices. Families once reliably hunted caribou by boat during their August to September migration, stocking freezers before winter. Now, herds often arrive in October or November, just as the ice begins its stuttering formation.
“Every day that people can’t go hunting or fishing is one more day of the year where the community is more food insecure, because a whole day of opportunity is lost,” said Alex Whiting, environmental program director for the Native Village of Kotzebue.
In the past, he said, when families could reliably hunt a half-dozen caribou in the fall, they could afford to wait until the ice was solid before heading out again. But with freezers empty and winter setting in, people are more willing to risk traveling on thin ice.
“There’s this extra impetus at play that’s egging you on,” Whiting said. “The caribou are here, they might be gone tomorrow. This might be my only shot for the entire year.”
The changes also threaten the food chain. Sea ice fuels the spring algal blooms, which sustain the plankton, fish and other critters whales, walruses and narwhals feed on.
“The ice is part of the annual pulse of the ecosystem,” said Andy Mahoney, a professor of sea ice geophysics at the University of Alaska Fairbanks.
Inland, ice season on Alaskan lakes and rivers has also shrunk by several weeks, according to a decades-long analysis.
“The Arctic only works when it’s frozen — that’s why it’s the Arctic,” Whiting said. “Everything up here has evolved to be frozen for a majority of the year. And when that isn’t the case anymore, it all starts to fall apart.”
Globally, lakes are losing some 17 days of ice cover per century, at a rate that has accelerated sixfold over the past 25 years, research shows.
The risk of drowning will eventually decline — not because conditions improve, but because ice will largely disappear, said York University’s Sharma.
“If we continue releasing greenhouse gas emissions at current rates, by the end of the century, thousands of lakes will no longer freeze and people won’t fall through the ice,” she said.
Back in Kotzebue, Jimmy Brown is still adjusting to life without his brother. They used to ride out into the tundra and gather firewood together, but Brown hasn't been able to bring himself to do those things alone.
He’s been attending Elmer’s daughter’s high school basketball games, trying to support her through her senior year.
“I know I can’t replace her dad,” he said. “I’m just thankful I can be there for her.”
