Year-To-Date Average Sea Ice Extent

2018 sea ice extent is still 2nd lowest on record, and will likely stay there for the rest of the calendar year.

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 2018 compared to other years.

Ten Year Average down every day for 25 years

Daily Arctic sea ice volume is up since September because of winter. The 1-yr average is slightly up over the same time due to a colder year. And the 10-yr average has been down every day for 25 years & 9 months because of climate change.

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.

Annual Average Sea Ice Volume

Annual average sea ice volume is still 5th lowest on record, and will also most likely end up 5th for the calendar year 2018.
