Heat waves that blanketed British Columbia in August and early September were made much more likely by human-caused climate change. Canadian climate scientists analyzed 10 of the hottest heat waves across the country in July and August, using a system that monitors extreme heat and cold events. Researchers found nine out of the 10 heat waves were made much more likely because of climate change. ECCC said one heat wave that hit Atlantic Canada from Aug. 7 to 14 stands out as being at least 10 times more likely to occur due to human-caused climate change. It also noted prolonged heat waves and longer fire seasons are major contributors to more frequent and intense wildfires across Canada.
