Environment Canada links human-caused carbon emissions to an increase in Arctic heat waves, 10 times more likely with temperatures 12-13 degrees above normal.

Environment and Climate Change Canada has determined that climate change has made heat waves in Inuvik, Kitikmeot, and Kivalliq at least 10 times more likely, with peak temperatures 12 to 13 degrees above normal. This is the first application of the highest level on the department's rapid attribution tool, which analyzes the impact of human-caused carbon emissions on extreme weather. The Arctic is warming faster due to melting sea ice, which exacerbates temperature increases.
