Summary(Plain Language Summary, not published)
The Geological Survey of Canada undertaken a study to determine if permafrost thawing could explain an observation, made by the local people, of lake level change near the community of Rankin Inlet, Nunavut. Knowledge of permafrost conditions is required to understand climate change impacts and to aid in developing adaptation solutions. Results indicated that some of the lake level change were due to permafrost thawing, triggered by climate change, while others responded to annual precipitation change. When permafrost thawing was involved, lake water level change was influenced by surficial geology units. This association between lake level change, permafrost, and surficial geology units is used to extrapolate permafrost conditions over a regional scale and assess how these terrain units could respond to warming climate.
