collapse of the old society

Looks bad. I also suggest looking here for better context:

My impression:

Ice extent is far below normal, 2023 is the worst year on recent record.

Ice volume has not responded dramatically yet (it has inertia) and there exists a year on recent record worse than 2023 - but it will respond soon enough.

Overall, I'm not sure if plotting a graph with standard deviations as the unit of measure is a good choice. It helps shake people up from sleep - yes. You typically look for standard deviations to determine if something is happening - and 6 deviations is considered solid proof. But to examine the quantity of ice, you measure square and cubic kilometers.
