September is underway, but experts say the start of Canada’s fall season – especially in eastern regions – could look more like summer.
These hot-weather temperatures are between 5 ° C and 8 ° C above normal and could persist until October, according to Anthony Farnell, chief meteorologist of Global News.
Farnell said major cities such as Toronto, Ottawa, Montreal and Halifax have maintained temperatures close to 20C, and these are expected to soar through their mid-twenties through the end of the month.
“When you have highs of around 28 degrees at the end of September in Toronto, it becomes rather unusual,” he said.
However, in western provinces like British Columbia, there has been more temperature reversal.
In recent months, British Columbia has experienced unprecedented and severe heat waves that have broken records and killed hundreds of people.
Alberta also suffered from a heat wave this summer as recorded temperatures hit 30C or higher and smoky air quality remained for nearly three weeks in August.
“We now have cooler conditions in BC and Alberta,” said Farnell.
Extreme weather events set to become more frequent in the face of climate change
Recently, temperatures have averaged around 15 ° C and 18 ° C in British Columbia and Alberta.
“(But there is) all kinds of heat and even humidity that are likely to persist until October for areas around the Great Lakes, Quebec and Atlantic Canada as well,” he said.
It is difficult to determine whether climate change is causing the latest wave of temperature increases.
On the one hand, scientists claim that there is a “clear link” between climate change and extreme weather conditions.
In August, the The Intergovernmental Panel on Climate Change released a report who warned the whole world – and with it, Canada – was on track for more devastating forest fires, smoldering heat waves and other extreme weather events if climate change was not reversed.
British Columbia’s third summer heat wave will peak on Friday and last until Sunday
But Farnell said the east coast has naturally warmer waters, adding that parts of Canada, including Ontario, Quebec and the Atlantic, have experienced a warmer September cycle for 15 years.
“It’s almost like the seasons have changed a bit, as we now get better weather in September and early October, then maybe more clouds, showers and cooler conditions for April and early May. He said, noting that Canada could also be for an earlier winter.
Gerald Cheng, a warning preparedness meteorologist at Environment and Climate Change Canada, said it was difficult to predict whether the rise in temperatures will last in the coming months, but he agreed with Farnell that September “is going to be over. from normal “.
“It’s less clear as we look at October and even further into November, the signal is coming back that it’s going to be above normal, but there is less confidence,” Cheng said.
