Arctic sea ice volume is currently 5th lowest, the 2019 Melt Season is just started. 2017 is the lowest year on record for volume, and you see it’s much lower than #2–5. 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.
