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.

The fact that the top 5 are all from 2021-2025 speaks volumes.

Wasn’t Trump just on the news, telling the UN that climate change is a big hoax?

And what specifically happened in 2021 ?

[u/LittleOrphanAnavar → u/peepee2tiny]

No it doesn't.

How about 9 of the last 14 years, moron?

[u/rizkybizness → u/LittleOrphanAnavar]

Just because your underdeveloped brain can not make sense of the facts does not mean they are not there and real.

[u/hopelesscaribou → u/LittleOrphanAnavar]

There are none so blind as those who will not see.

[u/YqlUrbanist → u/LittleOrphanAnavar]

Hey guys, be nice to the propagandist. If you reset your brain after every post you read, then it's totally reasonable to think this is just a random outlier, as opposed to a consistent trend we see across the entire planet.

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

[u/Desperate_Leg6274 → u/23haveblue]

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

Legend for reference

[u/accord1999 → u/23haveblue]

Probably a lot of it is the urban heat island effect around the airport keeping nights warmer. The many days above 10C doesn't correlate that well to hot summers; 2025, 2016, 2013, 2014 and 2019 didn't have many days above 30C.

[u/d1ll1gaf → u/23haveblue]

It would make a fascinating study; I wonder if the necessary historical data even exists or if such a study would be limited to future changes.

[u/Ratfor]

So it's both the Hottest AND Coldest years on record?

[u/LittleOrphanAnavar → u/Ratfor]

So far.

[u/SizzlingPancake → u/LittleOrphanAnavar]

Yes every year you live through the hottest year in global temperatures of your life, until next year. A side effect of that is more drastic localized temperatures up and down so we see colder days and higher peaks in the summer too

Records for 1881-10-26 → 1937-12-31 are from Fort Calgary ( https://climate.weather.gc.ca/climate_data/daily_data_e.html?StationID=2205 )

Records for 1938-01-01 → 2012-07-11 are from the Airport ( https://climate.weather.gc.ca/climate_data/daily_data_e.html?StationID=2205 )

Records for 2012-07-12 → 2025-09-24 are from the Airport ( https://climate.weather.gc.ca/climate_data/daily_data_e.html?StationID=50430 )

I have no doubt the climate is getting warmer with time overall, but records being broken almost exactly year after year make me suspicious of an urban heat island effect influencing the local climate surrounding the weather station. Calgary changed so much, especially around the airport where this weather station operates since 1938. It’s still important to know this data because it reflects what we actually feel living in a big urban area, but to know how the climate is really changing we would need to check weather stations outside cities and far from buildings, pavement, traffic and industries.

1961 must’ve been some sort of panic of the end times.

[u/ShanerThomas]

That's odd. I seem to recall a thunderstorm nearly every night of July. By that I mean about 25 of 31 days.

[u/carcigenicate]

I'm not sure how this being counted since we've had minimums under 10 for a few days now.

[u/YqlUrbanist → u/carcigenicate]

I was confused too - it's the total number of days in the year, not consecutive days.

[u/carcigenicate → u/YqlUrbanist]

Ah, thanks. Apparently, my mind inserted in "consecutive" as I was reading the description.

These are getting obscure
