If you live in europe, please check in with your elderly neighbours. Hot temperatures can be deadly for old people

      Whoever had to extend the scale in a hurry because the numbers were literally unthinkable when it was made. This year people who can have lunch in death valley national park are getting cooler temperatures than London.

      Those people near death valley are living in (mostly shitty) homes built for extreme heat, with central air thick insulation and light colored exteriors, double pane windows, entry vestibules in the nicer ones, all the things nobody in england has seen outside american TV.

    Not only are the colours bad, but the numbers are too? How is a max of 18 in summer worrying? We are way above those numbers.

        It goes red-black-white-red. And since temperatures rarely jumps 5°c without gradient, the map will have black and gray area surrounding any white that represents +13, and white will surround and red that represents +18°.

        I’ve just realised that this is saying that the UK is warmer than France. Because despite the term being white hot it’s actually decided that red is hotter than white. Why didn’t they just go from white being cold to red been hot?

      Exactly what I was thinking. There are 3 different off-white colors that indicate vastly different temperature variants. This map is incredibly ambiguous. Which white zones are -8° below average, roughly the same as average, or 13° above average?

      I might be the only one who doesn’t mind the color scheme. For the temperature range on the map, the only colors that don’t fit into the typical blue-to-red gradient are the green for really cold, which makes the coldest anomalies really pop, and the white for really hot. I get the complaints about white being used for both normal average temperature and for extreme heat, but it’s easy to tell which is which by the neighboring colors, and it almost looks as if France got so hot that it got a third degree burn, which chars the flesh, nerves included, and no longer feels like anything - thus insensate white.

      So MAYBE, and I’m pulling this out of my ass with no background here, but expectation is temperature doesn’t jump, but flows as a gradient. Using France as the start, we’ve white fading to dark greys then reds, which is the hottest of the three white possibilities. As going hotter then that gets pink again, the top end is white in France. We then decrease down the scale until we get those. green pockets. Light green/white touching green would signify the lower of the three white temps. Not a great map, but perhaps it’s an understood practice with the field. After all, how do you convert a quantitative scale into qualitative data. You can’t really just number everything (people have shit attention spans and they’ll gloss over immediately. Anybody who’s delivered technical data to management can attest to that lol) Color works well for that, but has a limited useful spectrum. Getting too specific in a single spectrum muddies the graphic (what’s the exact color over Lisbon here? This kinda salmony guy? So 8? Or closer to 9?)

        So there is a lot of work on this in color theory, and you can go deep into this… Here are a few chapters on the matter: https://slcc.pressbooks.pub/maps/chapter/9-2/ , https://courses.ems.psu.edu/geog486/node/876 , and this part in particular https://courses.ems.psu.edu/geog486/node/877

        Basically, their use of brightness within hue bins makes this a non-function. Notice how its gets whiter closer to 0 and closer to 13. If two values of Y can get plugged into a function and they both return 0 for the expected X term, thats a non-function.

        Temperature, or rather, difference in temperature from expected, which is whats being plotted here, is about divergence from normal.

        To fix this map, pick a divergent color scheme, center 0, then create bins at either a specific interval or at quantile intervals.

        Something like this: https://colorbrewer2.org/#type=diverging&scheme=RdYlBu&n=11

          While I do appreciate the information on better infographic creation, the example map has such a small range comparably. There’s over 30 values, not to mention the shades in-between values. I think a two color gradient would end up being very smooth at this scale. Sorta looks to generally drop in temperature as you go east here, nice red to blue fade.

          Expanding the color palette does give more room for distinction, but that’s seemingly how they got where they did.

          To be fair, from my friends who’ve actually had color theory and graphic design classes, STEM folks tend to do a poor job of communicating well.

          So eh. Maybe it’s pointless for me to argue against it.

            it’s a way of thinking about your audience, i think. when i worked in accounting and had to present to and teach accountants: simple formatted tables, stuff that looks like excel, it didn’t need to be bright or colorful. it just needed to have colors that were unobtrusive. i’m working in music now and if my seminars don’t have showmanship (and if i use powerpoint at all) i’m hosed. different audiences have completely different styles that they are used to communicating with, and if you adapt to that you’re going to have more success

            so like, i’m sure the STEM folk are fine at communicating within their field. outside? well, a few of my uncles were engineers. does it show?

    That is absolutely brutal. I really hope people are finding ways to escape the heat.

    Separately, this visualization is bad in a way I have never seen before: a scale of pink to dark red, where dark red actually represents 2 completely different numbers!

      Many just can’t escape it, for many reasons. People are dying, and this will only become more and more common and even worse. We only see the short term effects now too, it’ll be so much worse after some years when the long term effects become clear. Crops dying, water shortages, infrastructure damage etc.

      Deviation to the average temperature. So its 13 K above the average. Or in other words around 42-44°C

      Edit: oh you were complaining about the colormap? Yeah its super shit

      The color scale is definitely… a choice but it is not ambiguous. There is only one “path” that goes red, then black, then white.

    While yes, a 14c deviation from average temperatures is fucking insane, so is this map. The scale is cooked.

        +14C deviation is equivalent to +25F not 57. You don’t add the 32F for a deviation, only actual. Still an insane increase above normal though.

      It means that statistically, of the climate was constant, the temperatures we have now would be as probable as having 6°C.

      What’s it measuring against average temperature for this time of year because Europe does get hot at this time of year we know that. It’s also not as bad as the heat wave we had 6 weeks ago. Not too underestimate our awful the weather currently is.

        I assume it’s comparing against the average temperatures for June 21-26 as that would align with what my weather app says, which compares with the average temperatures since 1970

    so what is the unit? because it’s a hell of a lot warmer than 18C. Difference from… what historical average?

    it says 2m temperature anomaly and if it got 18 degrees C hotter outside in two minutes i think i’d just accept death. i must be misreading something.

    We used to have backbone. The count rised taxes too high and people picked up their pitchforks and torches. Now the rich elite makes planet inhabitable and no one cares to even complain about it loudly.

    The graph stops at 18°C, that’s the temperature it should be not the temperature that it is. Also why does it have two whites, white is apparently both zero and 13, which is bizarre because it’s definitely hotter than 13 everywhere in Europe right now and probably in Iceland as well. This map makes no sense.

    I honestly wouldn’t be able to cope in such temperatures. I’m glad Denmark is in the middle of the map here, wedged right in the sweet spot. Even then, it’s going to be unbearable next weekend and I’m slowly preparing for it.
