Western Canada was one of the hotspots on the planet during one of the hottest summers on record, according to an analysis.
“Canada, and particularly the western provinces, have been unusually hot this summer,” said Andrew Pershing, science director of Climate Central, which published its study linking greenhouse gases to daily temperatures in the world.
Climate Central used widely accepted and peer-reviewed methods that calculate the contribution of climate change to extreme weather events and applied them to daily temperatures between June and August in 202 jurisdictions around the world.
The study found that 98% of humanity was suffocating in temperatures that had become twice as likely to reproduce due to atmospheric carbon dioxide, all in the hottest period in recorded history, according to the Organization. global weather.
“No one is immune to climate change,” Mr. Pershing said.
Over the summer, Climate Central analysis showed that western and northern Canada, including northern Quebec, recorded temperatures 1.5°C above normal. It is the seventh highest figure in the world.
“These regions have experienced unusually hot and very persistent conditions,” Pershing said.
The researchers then analyzed to what extent these conditions might be attributed to climate change. They concluded that across much of the West Coast, for most of the summer, unusually warm daily temperatures were made three times more likely by greenhouse gases.
Large parts of Alberta suffered the same effect for up to 30 days.
Climate Central also looked at other Canadian cities.
The organization crowns Charlottetown as Canada’s Climate Change Capital. This summer, Prince Edward Island’s capital experienced 25 days when climate change made its daily thermometer reading at least three times more likely.
Yellowknife, St. John’s, Newfoundland and Labrador, and Halifax were next with 15 days of weather reaching the same mark.
If that bar is lowered to include weather twice as likely, Surrey, B.C. had 23 days. Iqaluit had 18 and Calgary had 16.
Devastating effect
This report is the latest evidence to suggest that climate change is having an increasingly devastating effect on Canada and the entire planet.
Earlier this week, data from the European Union’s Copernicus satellites showed average temperatures in June, July and August were the hottest on record globally, by two-thirds of a degree.
This summer, record wildfires also erupted across Canada, forcing thousands of people from their homes and burning 165,000 square kilometres.
The group World Weather Attribution has found that climate change makes summers like those that led to Quebec’s disastrous wildfire season at least seven times more likely to recur.
Andrew Pershing hopes Climate Central’s routine hot weather analysis will raise awareness regarding the pervasiveness of climate change across the planet.
Globally, the report concludes that the most severe effects of climate change are hitting those who have contributed least to it.
In 79 countries, climate change has made most summer weather three times more likely. Almost two-thirds of these countries were on the United Nations index of least developed countries. Together, these countries account for regarding 7% of global greenhouse gas emissions.
