Sunday daily Arctic sea ice volume was already lower than the September minimums of 24 years; 1979–2002, with about 70 more melt days to go. 2019 Melt Season average is 2nd lowest. Ten–Year Trend though, is still very stubborn.

Q: Where’s the data source for this plot?
A: Here: arctic-sea-ice-volume-for-june-2019-from-piomas/
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.

Due in large part to ongoing Collapse of Arctic Sea Ice our Frozen Earth is Going South.
