It was by chance that Camille Seaman first travelled north — a bumped flight on Alaska Airlines led to a free trip to Kotzebue on the Bering Strait.

Little did the San Francisco-based photographer know it was the beginning of a decade-long quest, an unshakable compulsion to take pictures of icebergs in some of the most extreme environments on Earth.

At the time, she simply wanted to document beauty in visually stunning vistas of the Arctic and Antarctica.

She wasn’t thinking about climate change then, but as the newest artist-in-residence at Denali National Park in central Alaska, it’s top of mind now. On her last Arctic sailing in 2011, she says there was almost no ice.

"There was nothing on the radar for ice," she said. "We could have kept going [to the North Pole], if we had enough fuel. It just shouldn’t be."

A grandfather’s teachings

Part Native American, Seaman attributes her environmental awareness to her childhood spent near the Shinnecock Reservation in New York State, and especially to the teachings of her grandfather.

He would take her for long walks in the woods to introduce her, individually, to trees.

"He really required that you stop at each tree and acknowledge it physically, place your hands on it and feel its life force, its physical structure, and understand it’s a relative to you."

'It's painful to see the devastation … to know what is being lost, and what we may not get back.' - Camille Seaman

She later brought her grandfather’s sensibilities to her polar art.

While working as an expedition photographer aboard science vessels and commercials ships, she approached each photograph of an iceberg as if it was a portrait of an ancestor: "I've never met two which were alike."

She compiled those photos and stories in a new book titled Melting Away: A Ten-Year Journey through Our Endangered Polar Regions.

"It's painful to see the devastation," said Seaman. "It's painful to know what is being lost, and what we may not get back."

Front lines of climate change

Though she stopped her polar explorations in 2011 — "I acknowledge I’m part of the problem" — she jumped at the opportunity to visit Denali because she sees Alaska as one of the front lines of climate change in the United States.

"No one can deny what Alaskans are experiencing and witnessing first-hand."

"I can't say making a photo is very important. In fact I feel sad it's all I can do. But that's what I'm gonna do." (Camille Seaman)

Scientists say climate change is altering the park's landscape in many ways — from forests of so-called "drunken trees" leaning against each other as permafrost thaws to tree lines creeping up the mountainside that affect habitat of the iconic Dall sheep.

Of course, there’s also Alaska’s retreating glaciers, which Canadian glaciologist Joanna Young views as canaries in the coal mine.

"They are a great metric to show us that climate change is real and that these changes are happening at an accelerating rate," said Young, who works at the University of Alaska.

"Once society realizes this is a real issue, we can start thinking more along the lines of mitigation and adaptation."

Seaman will be fresh off her residency at Denali National Park when she arrives in Vancouver this month to attend the 2015 TED (Technology, Entertainment, Design) Conference.

She was named a Senior TED fellow after her popular talks featuring her photos of icebergs and storm chasing.
