if you are thinking about downvoting, remember you can't be negative about it

Is that in Celsius, Fahrenheit, Rankine, Rømer, Réaumur, Delisle, Leiden, or Wedgwood?

I don't expect anywhere in Greece has been 0 F.

[–] Skua@kbin.earth 25 points 1 week ago (2 children)

Apparently January 1963 managed it, and by a fair margin too. The same weather system that caused the "Big Freeze" in the UK caught large chunks of the rest of Europe too, including taking Ptolemaida in Greece down to -28 C / -18 F

Wow. Cool, thank you. I don't mind being wrong.

This is the part of the map that makes me go uhm actually. I'm not sure if instruments with a bunch of decimal places ever did show exactly 0°. Of course, if we know that temperatures reached negative whatever at one point and positive whatever at another, then algebra tells us it must have been exactly zero at some point. That does not however mean that it was ever measured at that very exact moment of time. That also goes over the fact that the real world kinda isn't continuous regarding measurements once you go small enough thanks to the Planck's constant. Now, zero Kelvin is absolutely (heh) possible to achieve, but once you shift the scale? Idk I'm not a physicist; I just thought to myself hm did it ever show 0 or was it actually 0.0000001? Edit: I'm also tired and sick and there's a high chance that this comment is just my fever dream.

Fever dream. Get better soon.

wait, why are some countries grey?

[–] tanisnikana@lemmy.world 58 points 1 week ago (1 children)

They haven’t installed temperature yet.

It's bullshit you have to pay for what should have been a free update. Greedy devs at it again.

Here in Norway the scale goes from "Ferrjævelig" to "utepils". Numeric scales is an EU thing we didn't sign up for.

[–] Klear@quokk.au 1 points 1 week ago

I think I heard the first one from a unit in Age of Mythology.

[–] CaptainBlagbird@lemmy.world 10 points 1 week ago

Norway never had values at 0° or above

[–] JohnnyCanuck@lemmy.ca 8 points 1 week ago (2 children)
[–] yozul@beehaw.org 7 points 1 week ago (1 children)

Or alternatively they've only ever had temperatures below 0°.

[–] j4k3@lemmy.world 1 points 1 week ago

Is it consensual?

[–] L0rdMathias@sh.itjust.works 6 points 1 week ago

They only measure in Hot, so they won't have any cold data.

[–] Cat_Daddy@hexbear.net 4 points 1 week ago

Lack of data

[–] Lemminary@lemmy.world 3 points 1 week ago

Floor heating, probably.

[–] crazyminner@lemmy.ml 9 points 1 week ago (1 children)

I'm pretty sure zero Kelvin has never been measured.

[–] pressanykeynow@lemmy.world 4 points 1 week ago (1 children)

Can it even be measured? Won't any interference by the measurement raise temperature?

[–] crazyminner@lemmy.ml 2 points 1 week ago

I don't think you can know the absolute position of anything and having something at 0 kelvin would mean knowing it position.
