Annual Average Sea Ice Volume

In early March we went beyond the 14 mark for the first time since November 2016, by averaging higher than 14 thousand km³ sea ice volume. Now the worm has turned and we’ve been going down for about a week for the first time in 5 months, but of course, as soon as such a thing is published, the Arctic will twist and turn like the giant unpredictable Midgardsorm it is, or at least the pendulum will likely go back and forth a few times, before we truly know where we’re heading.

Q: Where’s the data source for this plot?
A: Here: http://psc.apl.uw.edu/research/projects/arctic-sea-ice-volume-anomaly/data/
Q: How can anyone make an annual average graph?
A: Easy. Use a computer. Add all the ice for the latest 365 days, divide by that number of days.
Q: Why would I even do that?
A: Let’s say you want to know how much ice we have in 2019 compared to other years.
