February 19th to 26th saw the second 1–week melt or compaction of sea ice in the 2019 Arctic. That is, the sea ice extent reported by JAXA was lower than 7 days before for the second time this year, be it primarily due to wind or actual melting of ice. Arguably, every single day of the year contains a combination of melt and freeze, or compaction and expansion, so clearly, we’re talking about a net melt.
Meanwhile, the much more important data for sea ice volume can be seen in this zoomed out 10–year chart:
Please help share this most important graph revealing persistent decline and a climate Tipping Point several decades back in our past: The true Tipping Point for ice is not at a future date or a yet to materialise future temperature threshold, it already happened.
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.
