Reply to comment by Few_Memory5631 in [OC] Map showing temperature anomalies over the northern hemispher on New Year's Day by sdbernard

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.

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

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.
