Environment and Climate Change Canada has released the most recent results of its effort to compare current climate models with pre-industrial weather models to understand how human emissions and activities are affecting weather today.
The June to September 2024 analysis looked at 37 of Canada’s hottest heatwaves occurring in 17 regions across the country. It found five were more likely to occur, 28 were much more likely to occur and four were far more likely to occur as a result of human-caused climate change.
Rising insurance claims
The report warns that Canada is warming at roughly double the average global rate. It also notes rising insurance claims and notes that 2023 was the second warmest year on record in Canada since nationwide estimates began in 1948. “From 1948 to 2023, the annual average temperature in Canada increased by two degrees,” they write.
Beginning this winter, Environment and Climate Change Canada says it will be able to use the Rapid Extreme Weather Event Attribution System to analyze the connection between human-caused climate change and the odds of extreme cold temperature events. “Work is also underway to develop the system to analyze extreme precipitation. This capability is expected to come online in 2025.”
