Red indicates a higher average temperature than the previous year; blue the opposite.

I'd just have thought they had some absolute scale going. It's a relative scale. This can lead to wildly wrong conclusions. Not in this case as the message would be the same mostly, but still.

Relative scale is worse. Not only that the temperatures keep going up and aren't a fixed "red", but that there's few to no blues now, meaning it's always going up everywhere. And this is actually a more calming way to present it that the usual exponential spike chart.

We need a color that's more alarming than red to switch to next

The temperatures are relative to the 1961-1990 average for that region, from the HadCRUT5 dataset.
Edit: I'm just going to find out if it's relative to the average, or just lowest value is blue, highest is red.

The footnote detailing this is maybe a little unclear.
