There’s been an ice meme gone viral, comparing apples to oranges, or rather land ice in Antarctica to sea ice in the Arctic, fooling and confusing everyone (see way below). So here’s a true 10–Year Challenge comparison for Arctic Sea Ice volume only.
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.
