Elmer Brown was following two friends on his four-wheeler last November, hunting caribou across a frozen channel in northern Alaska when the ice gave way. All three plunged into the frigid water. One friend drowned, and Brown later died of hypothermia, leaving behind five children.

“He was always helping other people and sharing his catch with the elders,” said his brother Jimmy Brown. “It’s been tough, not seeing him. I keep expecting him to walk in and tell me about his day.”

The tragedy underscores the changing climate in Alaska, where the ice that has long been a traditional hunting ground is becoming thinner and more unpredictable, leading to increased risks for those who depend on it.

The friends had ventured onto the ice to hunt caribou, driven by the urgency of shorter and less reliable hunting seasons.

The Brown brothers’ father drowned in 1999 while seal hunting. They are among thousands who have died on ice across the Northern Hemisphere as warming winters create conditions that are less stable and more dangerous.

In Alaska, where average temperatures have increased by 10 degrees Fahrenheit over the past 50 years, the ice season has become over 40 days shorter on average compared to the seventies.

“Every day that people can’t go hunting or fishing is one more day where the community is more food insecure,” said Alex Whiting, environmental program director for the Native Village of Kotzebue.

With the risks increasing, there’s also an increasing desperation to hunt even when conditions are dangerous. “The caribou are here, they might be gone tomorrow. This might be my only shot for the entire year,” says Whiting.

Studies show a global trend of lakes losing days of ice cover per century. The risk of drowning on ice is projected to decline not because conditions are improving, but because fewer bodies of water will freeze entirely.

As more traditional lifeways face threats from climate change, communities in Alaska find themselves grappling with loss, risk, and the struggle to adapt to indeterminate futures.
