(Click on "Antarctic", and then click "Show all years.")

Kinda hard to spin as "it's all a part of natural variability" when the graph looks back at you like that.

* The Arctic graph is also interesting. At first sight it doesn't look that bad, until you zoom in and realize that the bottom of the graph is pretty much entirely 2010s and 2020s.

Edit: Oh, actually you can just change the color scheme and see the Arctic graph sliding down over time! Neat.
