The Year–To–Date average is still 2nd lowest for sea ice volume in the Arctic. The full year 2019 will likely be 2nd lowest, maybe 3rd, and less likely lowest on record. Note the difference of 4,000 km³ back to the 2000s average from the 2010s. That’s climate change for ya.
A: Here: Arctic Sea Ice Volume for September 2019 from PIOMAS
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.
Due in large part to ongoing Collapse of Arctic Sea Ice our Frozen Earth is Going South.
