There simply isn't a winter in Quebec this year. 😭 Jan 7 still no snow on the ground! I was hoping to never see this...

This is a great visualization of one of the fundamental pieces of climate change: places are going to feel extreme changes to formerly fairly consistent weather patterns.

It’s shorts weather in Svalbard in January! And this is just two weeks after it was 30 degrees below average in Chicago on Christmas Eve. On average the globe warms a few degrees, but boy howdy are we feeling the effects in different ways.

Can anyone explain the temperature key/coloring? Shouldn’t 0 C be at the same position as 32 F?

It appears that the colors represent the difference between the Jan 1 temperature and the average temperature 1991-2020 for January. I was confused at first too, there shouldn’t be 20C temps in the arctic circle.

It displays the difference in temperature between this year and the mean over 1990 to 2020. It is not the temperature of the places. Since we are computing a difference if the temperature this time was the same as the previous ones the difference would be zero being it Celsius or Fahrenheit, and since Fahrenheit increases faster than Celsius they don't have the same value when the difference in temperature is different from zero.

Exactly this, it's a temperature anomaly map. This shows the temperature difference from the long term average (1992-2020). It's much more effective than a normal temperature map because you don't have to be familiar with what normal temperatures should be in each region to understand how unusual they are

Tipping points folks. Wait for the tipping points. That’s when the dominoes will start to tumble and I honestly believe they will fall much faster than anyone can comprehend.

If anything this chart should be “data is horrifying” not “data is beautiful.”

Coldest temperature should be represented by the darkest blue considering you have used the darkest red

I get the sentiment of the mapping exercise, however I can't overlook what appears to be a bias in the gradients used in the scale.

Perhaps someone can explain why +20*c scales so very much darker than -20*c. This is not typically what you see when using color gradients to represent values.

Well not in the eastern township where I live and when I was a kid, by this time of the year there was like 2 feet of snow ... not a trace.

Pretty much all ski resort are closed or partially open in the dead of winter

It is normal to have -25 in Poland? I seriously doubt that.

Edit: This website says, that the coldest day on record had a temperature of -25.1C. Also current temperature in Warsaw is 5C. It is unlikely, that the temperature would fall by 30 degrees just little up north.

I hope Ukraine and the rest of Europe have a record warm winter only to fuck over Russia even more.

Can you explain the color choices for the gradient, why are you using a seemingly intentionally more rich color pallet & depth for +20*c vs a very muted blue for -20*c?

Did the data alone not paint the fiery globe image you wanted to project? You may as well have manipulated the data.

This is not beautiful data, it is a subjective abuse of color to paint a story the data alone didn't tell.

If you would have used a more honest color scale, this map would show that basically molto of the map, apart from the streak on the artic and the one in east Europe, are reasonably on average, with what I can guess (it's really hard to be determined in your messy yellow to black color gradient) is ±5°C. Which on a single day is honestly incredibly consistent. Though again, really hard to comprehend since yellow goes to orange to dark orange in a very small degree range.
