Four Year Average at new Record Low

In the Arctic, the sea ice volume 4-yr average reached a new record low last week due to climate change. The new milestone was 13.6 thousand km³.

Q: How can anyone make a 4–year average graph?
A: Easy. Use a computer. Add all the ice for the latest 4×365 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 the latest 4–year period compared to the 4–year periods before that.

Annual Average Sea Ice Volume

The 365–day running average for sea ice volume is now lower than 13.78 thousand km³ and dropping by about 92 km³ per month. The prognosis suggests 2019 may go 2nd lowest on record for all–year average.

2018 Minimum Destroyed on August 16 | Arctic Sea Ice Volume

Friday’s daily Arctic sea ice volume was already lower than the September minimums of 35 years; 1979–2009 + 2013–15 + 2018, with about 30 more melt days to go. 2019 Melt Season average is 2nd lowest. Ten–Year Trend though, is still very stubbornly all–time low.

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.

Sea Ice Extent Minimum | Top 5

Arctic sea ice extent went below 6 million km² during July for the first time on record, yet 2012 was first below 5. Chart shows 2012 as lowest in mid August. We have until August 22nd to beat the 2012 record for first below 4.

Q: Why only 5 years and why these particular years?
A: Elementary. These are the 5 years on record that came closest to a Blue Ocean Event.

Sea Ice Volume Minimum | Top 5

Arctic sea ice volume went below 6 thousand km³ record early (just as for 10, 9, 8 & 7). But the chart shows we didn’t quite manage to beat the 2012 record for first below 5 by August 13th.

Year-To-Date Average Sea Ice Volume

The Year–To–Date average volume is now 2nd lowest for sea ice in the Arctic. Next target is record low 2017. Note also that the 2000s average is still not below the 21k upper edge, while this year’s at 17.3. That’s climate change for ya.

Year-To-Date Average Sea Ice Extent

The Year–To–Date average extent is still 2nd lowest for sea ice in the Arctic. All 4 lowest years are also the 4 latest years: 2016, 2017, 2018 & 2019. Next target is record low 2016.

Arctic sea ice extent meltdown

Arctic sea ice extent meltdown has come 70% of the way from Winter Maximum to a Blue Ocean Event per August 11th. The lowest extent year ever, 2016, for comparison, was at 65%.

Q: Where’s the data source for this plot?
A: Here: https://ads.nipr.ac.jp/vishop/#/extent
Q: How can anyone know if there is a Blue Ocean Event?
A: Easy. Use a computer. If you have less than 1 million km² sea ice extent in the Arctic, then you have a Blue Ocean Event.
Q: Why would I even do that?
A: Let’s say you want to know when the Arctic Ocean goes ice–free. Basing this on satellite measurements instead of gut feeling makes your conversations more interesting.

Arctic sea ice volume meltdown

Arctic sea ice volume meltdown has come 79% of the way from Winter Maximum to a Blue Ocean Event per August 10th. The lowest volume year ever, 2017, for comparison, was at 76%.

2007 Destroyed on August 1 | Arctic Sea Ice Volume

Friday daily Arctic sea ice volume was already lower than the September minimums of 33 years; 1979–2009 + 2014–15, with about 40 more melt days to go. 2019 Melt Season average is 2nd lowest. Ten–Year Trend though, is still very stubbornly all–time low. Interestingly, the once record low shocker 2007 was crushed by 2019 as early as August 1st.
