MELISSA BLOCK, HOST:
You're listening to ALL THINGS CONSIDERED from NPR News.
Nelson Kanuk is suing the state of Alaska. Kanuk is an 18-year-old Yupik Eskimo. His house stands on melting tundra, and he says the state most do more about climate change.
Here's Ed Ronco of member station KCAW.
ED RONCO, BYLINE: Nelson Kanuk dashes across the gymnasium at Mount Edgecumbe High School in Sitka. He's enrolled in EMT class, and today is his first CPR test.
NELSON KANUK: Starting compressions. One, two, three, four, five...
RONCO: He delivers chest compressions to a plastic mannequin while his partner runs to grab the emergency defibrillator on the gym wall.
KANUK: ...19, 20, 21, 22...
RONCO: Nelson and his partner work furiously to save the mannequin. But outside of class, and a thousand miles away from this state-run boarding school, the high school senior hopes to save something much bigger and much more real: his home.
KANUK: The river that runs in front of my house is called the Kugkaktlik River, and it means the middle one in the Yupik language.
RONCO: Nelson is from a Yupik Eskimo village called Kipnuk. There are no roads in or out, so the river is the village's main highway. It's seven hours by motor boat to the nearest town. And now that the permafrost isn't so perma, something is happening to Nelson's yard.
KANUK: It's disappearing.
RONCO: When the river ice moves out in the spring, it carves away at the bank. Last spring, the Kanuks lost eight feet from their yard.
KANUK: And then, as the summer progressed, we lost another five feet.
RONCO: How much is left before it gets to your house?
KANUK: Last fall, before I left, there was about 40 feet or so. But when springtime comes, there's definitely going to be a couple more feet that will be lost.
RONCO: This is how his family has lived for generations, on a river delta in western Alaska, where the land provides what the local store cannot.
KANUK: We actually go out into the tundra, and we harvest salmonberries. And we actually go out into the river, and we fish for salmon. And then we go out to the ocean in the springtime, and that's how we get the seal meat that we need to help us survive in the wintertime.
RONCO: Nelson Kanuk is one of six young Alaskans suing the state, with help from the organization Our Children's Trust. The Oregon-based nonprofit filed lawsuits on behalf of young plaintiffs against nine states and the federal government.
The lawsuits ask the states to consider the atmosphere a public trust and to exercise their duty to protect it. Part of the argument is that if the state of Alaska can manage other natural resources under its control, for example, by issuing hunting or fishing licenses, it should also be able to manage what's released into the atmosphere.
Seth Beausang, a lawyer for the state of Alaska, says he understands part of the argument.
SETH BEAUSANG: But the state has almost no control over the concentration of greenhouse gases in the atmosphere because that is determined by global emissions of greenhouse gases.
RONCO: Beausang says the issue of whether the state should regulate the atmosphere doesn't belong in the courts at all.
BEAUSANG: We say that it is more consistent with democratic principles for Alaska's elected representatives to be making policy in this area. We think the legislature and the governor should be making policy, not a single superior court judge.
RONCO: But Nelson Kanuk says the political process might be too slow, especially as he watches the river move closer to swallowing his home.
KANUK: It's not a few years anymore. It could be within the next year.
RONCO: A state court judge in Anchorage dismissed Nelson's case, and he's appealing that decision. He says he understands some people might view an eroding river bank as a consequence of living in a remote wilderness, but he doesn't see it that way.
KANUK: It's not different from your home because that is where we live. And it's a part of who we are, and it's the same with you.
RONCO: What happens to Nelson's home depends on river ice and permafrost, but what happens to Nelson's case is up to the Alaska Supreme Court. It's expected to hear an appeal sometime this year.
