So how much ice did we lose from the previous decade to this one? Let’s start with the good news, shall we? We lost only 6.5% flat, 2D surface cover. What the bad news is? Well, we lost 21.7% of the sea ice. So there’s that.

Q: Where’s the data source for this plot?
A: Here: Ice Volume for August 2019 from PIOMAS and here: https://ads.nipr.ac.jp/vishop/#/extent
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.
