Climate change made December’s hyper-warm weather across Canada at least twice as likely, concludes a new rapid analysis released this morning.
The analysis shows most of the country with a “detectable climate footprint” that drove up daily temperatures through much of the month, Princeton, NJ-based Climate Central reports. That was the case for 13.9 days out of the month in the Northwest Territories, 13.8 days in Nunavut, 11.2 days in British Columbia and Ontario, 9.9 days in Manitoba, and 9.3 days in Quebec.
Six out of 10 provinces and one out of three territories recorded their warmest December since 1970, the four-page report finds.
“Much of the country, especially the central provinces, had monthly temperatures more than 5°C above the long-term (1991-2020) average,” Climate Central states. “The three most unusually warm provinces were Manitoba (8.6°C above normal), Saskatchewan (8.0°C), and Alberta (7.1°C), but every province and territory was above normal,” with Nova Scotia recording the smallest anomaly at 2.4°C.
