| Abstract | Climate and ground temperature records 10 to 30 years in length from four widely separated permafrost monitoring sites were analyzed to assess the thermal response to recent climate warming, both
seasonally and annually. The study sites are located in the tundra environments of Nunavut and the boreal forest of the Mackenzie Valley Northwest Territories. The timing and magnitude of the climate change varied regionally, and the response of the
ground varied even more due to individual site conditions. Increases in winter air temperatures were significant and appear to be largely responsible for recent increases in ground temperature. |
