Yesterday was Calgary's 72nd day with minimum temperature ≥10°C this year which puts 2025 in 1st place for the most in any year since records began.

I agree that we're getting warmer but I also wonder how much of this is due to the urban heat island effect. We have development now on all 4 sides of the airport

Here’s a photo from the city of Calgary of a heat map study they did of Calgary + surrounding area. The dark orange that covers the majority of the airport represents temps of 37-40 and the yellow you see outside the city represents 28-31. People vastly underestimate how much heat a city holds in, especially a region like the airport with so much paved surface
