加拿大环境部将人为碳排放与北极热浪的增加联系起来,如果温度超过正常水平12-13度,其概率是正常温度的10倍。 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.

加拿大环境和气候变化部确定,气候变化使Inuvik、Kitikmeot和Kivalliq的热浪的可能性至少增加了10倍,高峰温度比正常温度高出12至13度。 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. 这是在部门快速归属工具上首次应用最高层工具,该工具分析人为碳排放对极端天气的影响。 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. 由于海水冰层融化,北极变暖速度加快,使气温上升加剧。 The Arctic is warming faster due to melting sea ice, which exacerbates temperature increases.
