Residents of towns and villages in Arctic Alaska live on “the front line of climate change.” Some communities face immediate threats from erosion and flooding associated with thawing permafrost, increasing river flows, and reduced sea ice protection of shorelines. The term climigration, referring to migration caused by climate change, originally was coined for these places. Although initial applications emphasized the need for government relocation policies, it has elsewhere been applied more broadly to encompass unplanned migration as well. Some historical movements have been attributed to climate change, but closer study tends to find multiple causes, making it difficult to quantify the climate contribution. Clearer attribution might come from comparisons of migration rates among places that are similar in most respects, apart from known climatic impacts. We apply this approach using annual 1990–2014 time series on 43 Arctic Alaska towns and villages. Within-community time plots show no indication of enhanced out-migration from the most at-risk communities. More formally, there is no significant difference between net migration rates of at-risk and other places, testing several alternative classifications. Although climigration is not detectable to date, growing risks make either planned or unplanned movements unavoidable in the near future.

Climate change is a major challenge to Arctic and other Indigenous peoples, but not the only and often not the most pressing one. We propose re-framing the treatment of climate change in policy and research, to make sure health, poverty, education, cultural vitality, equity, justice, and other topics highlighted by the people themselves and not just climate science also get the attention they deserve in research on global and regional environmental change. Climate change can often exacerbate other problems, but a singular focus on climate change—as is often the case in much existing environmental literature on the Arctic and elsewhere—can distract from actions that can be taken now to improve the lives of Arctic peoples. The same logic also applies elsewhere in the world, where diverse residents face a host of challenges, opportunities, and obstacles, with climate change but one among many issues. Our proposed approach to regional and global environmental change research draws on the ideas of decolonization, emphasizing collaborative approaches and Indigenous voices in research and policy instead of top-down measures designed outside the affected communities. Only in this way of contextualizing human-environmental experiences can the full effects of climate change be understood—and appropriate responses developed and carried out to adapt to global change.

Marine mammals are important sources of food for indigenous residents of northern Alaska. Changing sea ice patterns affect the animals themselves as well as access to them by hunters. Documenting the traditional knowledge of Iñupiaq and Yupik hunters concerning marine mammals and sea ice makes accessible a wide range of information relevant to understanding the ecosystem to which humans belong. We interviewed hunters in 11 coastal villages from the northern Bering Sea to the Beaufort Sea. Hunters reported extensive changes in sea ice and weather that have affected the timing of marine mammal migrations, their distribution and behaviour and the efficacy of certain hunting methods. Amidst these changes, however, hunters cited offsetting technological benefits, such as more powerful and fuel-efficient outboard engines. Other concerns included potential impacts to subsistence hunting from industrial activity such as shipping and oil and gas development. While hunters have been able to adjust to some changes, continued environmental changes and increased disturbance from human activity may further challenge their ability to acquire food in the future. There are indications, however, that innovation and flexibility provide sources of resilience.
