在加拿大北部的伊格卢利克、乌鲁哈托克和丘吉尔社区进行的研究表明，与用于狩猎和旅行的冰有关的危险暴露越来越多。这一趋势与冰层条件的变化有关。仪器记录显示，自20世纪70年代末以来，较晚的冰冻和较早的解冻，导致气温上升，以及案例研究社区的天气变化。长老和成熟的社区成员利用他们的传统知识，描述了近年来冰层和其他与气候有关的条件的类似变化。这些变化增加了利用冰进行狩猎和旅行的风险，并减少了获得传统食物的机会。在过去的几十年里，伊格卢利克和乌鲁哈托克也记录了冰使用者冒险行为的变化，并影响了最近冰情变化的影响。社区之间的比较显示，冰条件变化的后果参差不齐，这与冰使用的性质、当地的生理环境和社区的社会文化动态有关。
Research conducted with the communities of Igloolik, Ulukhaktok, and Churchill in northern Canada documents increasing exposure to hazards associated with ice use for hunting and travel. This trend is related to changing ice conditions. Instrumental records show later ice freeze-up and earlier breakup since the late 1970s, increasing temperatures, and changes in weather in the case study communities. Elders and mature community members, drawing upon their traditional knowledge, describe similar changes in ice and other climate-related conditions in recent years. These changes are increasing the risks of utilizing the ice for hunting and travel and they are reducing access to traditional food. Change in risk-taking behavior among users of the ice has also been documented in Igloolik and Ulukhaktok over the last few decades and has shaped the implications of more recent changes in ice conditions. Comparison between the communities reveals uneven consequences of changing ice conditions which is linked to the nature of ice use, local physiological setting, and community socio-cultural dynamics.
