NUUK, GREENLAND—Nikkulaat Jeremiassen was 6 years old when he was tasked with holding the fishing net on his father’s boat, gripping the ropes tightly in his little fists to prevent the day’s catch from escaping. Not long after, he had a 20-caliber hunting rifle shortened to suit his small frame. He was given an old fishing boat when he was 15 and was soon a self-employed fisherman. During the summer months, he would often sleep for only an hour a day for weeks on end, working overtime to stock up for the lean winter ahead—a common routine among the sea-bound workers. Fisheries are an important industry in Greenland, providing over 90 percent of the island’s exports. But even before its industrial expansion, fishing was a source of sustenance and cultural pride for Greenland’s Inuit people. Fathers taught their sons to fish and hunt using the sea ice, and to follow their prey’s migration patterns through the seasons, Jeremiassen remembers. Now, Jeremiassen, 64, is watching as warming temperatures threaten these Inuit traditions and the Greenlandic way of life he grew up with. He’s practiced traditional hunting and fishing for as long as he can remember, but future generations may not be able to say the same. Much of Greenland is above the Arctic Circle, where temperatures are climbing nearly four times faster than the global average as the build-up of greenhouse gases from fossil fuel combustion and other human activities warm the atmosphere. The Greenland Ice Sheet—which covers about 80 percent of the island—has shed around 270 billion metric tons of ice annually since 2002, while the sea ice that normally rings the island’s coastlines is growing thinner and less stable. The retreating ice has made Greenland more accessible to the world and exposed rare earth minerals that have piqued the interest of developers and the administration of U.S. President Donald Trump, who called U.S. control of Greenland “an absolute necessity” and has not ruled out the use of military force to acquire the island. But for Greenland’s Indigenous Inuit people, who make up most of the island’s population, these environmental changes are undermining the fishing, hunting and strong ties to nature that have long defined their culture, making it harder to practice their traditions and pass on generational knowledge. Inuit communities feel the effects of climate change in many aspects of daily life, through disrupted livelihoods, food insecurity and housing problems, and in changes to their cultures and identities. Ninety-two percent of Greenlanders believe climate change is occurring, and 76 percent say they have personally experienced its effects, according to a 2019 survey conducted by the University of Copenhagen, the Kraks Fond Institute for Urban Economic Research and the University of Greenland. A majority of respondents think climate change will harm sled dogs and hunting, and about half say it will negatively affect fishing. Mental health experts say climate change is driving stress and feelings of disconnection from Inuit culture that could add to the pile of risk factors affecting native Greenlanders’ psychological well being. Though sparsely populated, Greenland has frequently had one of the world’s highest suicide rates. “Nature is like a healing place. We understand the nature, the nature understands us,” said Arnârak Patricia Bloch, a doctoral student at the Center for Public Health in Greenland studying youth suicide and a Greenlandic suicide prevention instructor. “The only thing we can heal from is now being affected with climate change.”
