How does climate change impact Inuit trail use? Check out this new publication to find out!

In an article published in Nature Climate Change, we use 30 years of instrumental data in combination with Inuit knowledge to examine how access to trails could be impacted via climate change. We find that climate impacts on trail access is modified by trail user’s risk tolerance and skill level.


Inuit trail use in a changing climate

New article published in Nature Climate Change



Arctic climate change has the potential to affect access to semi-permanent trails on land, water and sea ice, which are the main forms of transport for communities in many circumpolar regions. Focusing on Inuit Nunangat (the Inuit homeland in northern Canada), trail access models were developed drawing upon a participatory process that connects Indigenous knowledge and science. We identified general thresholds for weather and sea ice variables that define boundaries that determine trail access, then applied these thresholds to instrumental data on weather and sea ice conditions to model daily trail accessibility from 1985 to 2016 for 16 communities. We find that overall trail access has been minimally affected by >2 °C warming in the past three decades, increasing by 1.38–1.96 days, differing by trail type. Across models, the knowledge, equipment and risk tolerance of trail users were substantially more influential in determining trail access than changing climatic conditions.
