Arctic Sea Ice Volume

Yesterday daily Arctic sea ice volume was already lower than the September minimums of 8 years; 1979-80, 1983, 1986-89 and 1992, with about 90 more melt days to go. 2019 Melt Season average is 3rd lowest. Ten–Year Trend though, is still very stubborn.

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 a decadal average graph?
A: Easy. Use a computer. Add all the ice for the latest 3650 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 the latest decade compared to the decades before that.
