Climate Change Increases Likelihood of August Heat Waves in Canada

Environment Canada reports that human-caused climate change made some northern heat waves at least 10 times more likely.

Environment Canada's rapid analysis tool indicates that August heat waves in Inuvik, Kitikmeot, and Kivalliq were significantly influenced by climate change.
The rapid attribution tool, currently in its pilot phase, has linked human-caused carbon emissions to increased frequency and intensity of extreme weather events.
Seven other heat waves across Canada in August were found to be two to ten times more likely due to climate change, with one in Manitoba being one to two times more likely.
The Arctic is experiencing faster warming than other regions, partly due to Arctic amplification and melting sea ice.
Prolonged heat waves contribute to more intense wildfires, with the 2023 wildfire season burning nearly 15 million hectares of forest in Canada.
