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!

The product of human activity, Donald Trump's deregulations, everyone trusting China with their manufacturing (given their own lax systems of regulation), and the rampant building of data centers.

We are all partially guilty, and the phrase "fry in hell" is of our own making.

There seems to be three different values for white.

@A404 States around the world absolutely fucking failed regarding Climate Change.Be it mitigation or prevention even the bare minimum was too much to ask for.Here in Germany activists even won a lawsuit upholding the law? To quote Proudhon : "Laws: We know what they are, and what they are worth! They are spider webs for the rich and mighty, steel chains for the poor and weak, fishing nets in the hands of government."

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

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?

Like I don't have time to get into it cus I'm at work, but their use of hue is a non-function the color space.

The neighbouring colors are different though, so since it's not going to jump from +10 to -8 you can unequivocally tell. Honestly I think I hate this less than having 8 shades of slightly different red

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

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.

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.

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

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.

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?

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.

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.

This will probably start to change if this is now the reality but at least historically the reason Europe didn't have air conditioning was it wasn't worth it for the 4 days of the year that it would be used.

The other reason being that houses won't design to be air conditioned, we don't have ducted heating so if I bought an air conditioner and had it installed in a room it would air condition that room, if I wanted air conditioning in my house I would have to have a unit fitted in each room, that's going to get expensive. Alternatively I could buy this £15 fan from Lidl.

I think the 2m is for temperatures taken two meters off the ground. What the data range for the average is though, impossible to tell.

The scale is "temperature anomaly" so this is deviation from the norm, not the temperature itself
