Year-To-Date Average Sea Ice Extent

The Year–To–Date average extent is still 6th lowest for sea ice in the Arctic, but the YTD graph peaked record early this year, just as predicted on this site, and will likely go 5th lowest by the end of this week.

Q: Where’s the data source for this plot?

Q: How can anyone make a year-to-date average graph?
A: Easy. Use a computer. Add all the ice for every day so far this year, divide by the 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.
