Nunavut climate outlook: 10 C winter warming, permafrost carbon, and the shift away from diesel

Canada's Changing Climate report projects that winter temperatures in Nunavut could rise more than 10 C by 2100, with permafrost thaw, coastal erosion, and record-low sea ice already reshaping the territory. The report warns that Arctic permafrost holds up to three times the carbon in the atmosphere, so thawing ground could release large amounts of CO2 and methane, making future warming harder to stop. The article also covers adaptation work in Nunavut, including thermosyphon systems in buildings and the Government of Nunavut's mapping of permafrost and climate hazards. On the energy side, a new solar project in Naujaat now supplies 30 percent of that community's electricity, part of a push to cut diesel reliance. Canada remains far from its 2030 and 2050 climate targets, but the report's authors say sustained action could still stabilize temperatures later this century.
