Annual Average Sea Ice Extent

In mid April we went back below the 10 mark, by averaging lower than 10 million km² sea ice extent. The worm has turned, and explicitly suggested in a dotted way below, is the possibility of 2nd lowest or a new record low for the full calendar year. Arctic sea ice extent has also been lowest on record for the date for 17 consecutive days.

Q: Where’s the data source for this plot?
A: Here: https://ads.nipr.ac.jp/vishop/#/extent
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.
