The 365–day running average for sea ice volume is still 2nd lowest and lower than 13.63 thousand km³, dropping by about 55 km³ per month. The prognosis suggests we’ll go lower than 2012 for the all–year average, pushing 2012 to #3 for low sea ice.

Q: How can anyone make an annual average graph?
A: Easy. Use a computer. Add all the ice for the latest 365 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 2019 compared to other years.
Due in large part to ongoing Collapse of Arctic Sea Ice our Frozen Earth is Going South.
