Climate change contributed to big Canada fires, study says as Trump blames mismanagement
Summary
A new study found that human-caused climate change doubled the chances of the hot and dry weather conditions that led to Canada’s large wildfires this summer. The fires caused smoke to spread widely and led U.S. President Donald Trump to blame Canada’s fire management, while scientists pointed to global warming as the main cause.Key Facts
- Human-caused climate change has made extreme fire weather conditions twice as likely in parts of Canada.
- The study was done by World Weather Attribution, a group that looks for climate change impacts on extreme weather.
- The research compared current conditions to a hypothetical world without 2.5 degrees Fahrenheit (1.4 Celsius) of warming since the industrial era.
- The weather linked to the fires involves heat, low rain, humidity, and wind, creating “tinderbox” conditions.
- The wildfire weather this year in Ontario happens roughly once every six years now, but before the industrial age, it might have happened only once in a lifetime.
- Scientists said hotter and drier weather from burning fossil fuels causes more frequent and intense fires.
- President Trump blamed Canadian mismanagement for the fires and smoke that affected the U.S.
- Experts say the U.S. has also contributed heavily to climate change due to its past burning of coal, oil, and gas.
