Extraordinarily Warm Fall a Big Problem in Canadian Arctichttps://www.ctvnews.ca/canada/extraordinarily-warm-fall-a-big-problem-in-canadian-arctic-1.4699973For Keith Morrison, the consequences of this fall's extraordinarily warm weather across the North all came down to an urgent call for help. The fire chief for the Arctic community of Cambridge Bay in Nunavut was at home the evening of Oct. 6 when he got word that a couple had fallen through the ice near a river mouth.
"It was pitch black," Morrison recalled. "It was a close thing."
It shouldn't have been a thing at all. That stretch of ice is normally safe by this time of year, but this autumn has not been normal.
"What differentiated this year was we saw a widespread warmer temperature anomaly across the board in the Arctic," said Environment Canada meteorologist Eric Dykes. "Temperature anomalies that are five degrees above normal are happening a little bit more readily than they have in years past."
Data from around the Arctic bear him out.
In Inuvik, N.W.T., temperatures on every single day between Sept. 1 and Nov. 11 were above normal. In Nunavut, Pond Inlet had only one day of below normal, while above-normal days occurred about 80 per cent of the time in the communities of Cambridge Bay and Pangnirtung.
Not only were temperatures warm, the amount of warming was noteworthy.
The Canadian Forces Station at Alert, on the top of Ellesmere Island, broke a record for Sept. 6 this year by six degrees. Pond Inlet experienced one day that was 11 degrees warmer than average.
And not only did Resolute, Nunavut, record 68 days of above-normal warmth, nearly half of those days were outside the normal temperature variation. Kugluktuk, Nunavut, was similar -- 58 warmer-than-average days, 34 of them outside the normal range.
... It's not the only change.
"There have been more sightings of killer whales, increasing every year," Arreak said.
"Insects are being reported that aren't usually around the area. We don't even know what they're called."
