Annual Average Sea Ice Volume

The 365–day running average for sea ice volume is now lower than 14.05 thousand km³ and dropping by about 60 km³ per month. The prognosis suggests 2019 may go 2nd lowest on record for all–year average.

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.
