Canada releases June and July results from rapid extreme weather event attribution system
Environment and Climate Change Canada has analyzed the heat waves that impacted Canada in June and July using its Rapid Extreme Weather Event Attribution system. The system uses climate models to compare today’s climate to a pre-industrial one to explain how much human-caused climate change affected each heat wave’s likelihood.
Using this system, climate scientists analyzed the heat waves experienced in the following regions and determined, in all instances, that human-caused climate change made these heat waves much more likely. This means that human influence on the climate made these events at least 2 to 10 times more likely to happen.
Understanding the causes and risks of extreme weather events can help Canadians make informed decisions that protect the health, safety, and long-term well-being of our communities. Prolonged heat waves are a major contributor to more intense wildfires across Canada. The 2023 wildfires in Canada burned almost 15 million hectares of forest and cost Canadians tens of billions of dollars in damages.
Environment and Climate Change Canada urge the public to regularly monitor weather forecasts, take all weather alerts seriously, and get prepared for weather-related events by developing an emergency plan and being ready to adjust their travel plans. Canadians can download the WeatherCAN app to receive weather alert notifications directly on their mobile devices. Alerts help Canadians prepare to face severe weather events, save lives, and reduce the impacts on property and livelihoods.
