Since New Year we’ve climbed from 2nd lowest annual average sea ice extent on record in the Arctic, back up to 4th lowest, and per now it seems very likely we’ll go higher than 10 million km² this month, for the first time since June 2016.

½ Year Arctic Blue Ocean Estimates
Our first ½ year long Arctic Blue Ocean Event could come as early as 2025. No sea ice for 6 months, in as little as 6 years?

Year-To-Date Average Sea Ice Volume
The average for the year for Arctic sea ice volume is still 6th lowest per March 4th, but fast approaching 7th lowest. These are however still early days, and a 63–day average, while much more reliable than just a daily figure, is a lot less indicative of where the year is going than, say, a …
Year-To-Date Average Sea Ice Extent
The average for the year for Arctic sea ice extent is up from 5th to 6th lowest per March 3rd. These are however still early days, and a 62–day average, while much more reliable than just a daily figure, is a lot less indicative of where the year is going than, say, a 100–day or …
Arctic sea ice volume refreeze
Arctic sea ice volume refreeze has come 90% of the way since Summer Minimum per March 1st. The lowest volume year ever, 2017, by the same date, was at 78%. Q: Where’s the data source for this plot?A: Here: http://psc.apl.uw.edu/research/projects/arctic-sea-ice-volume-anomaly/data/Q: How can anyone know if there is a full refreeze?A: Easy. Use a computer. If you …
Arctic sea ice extent meltdown
Arctic sea ice extent meltdown has come 2% of the way from Winter Maximum to a Blue Ocean Event per February 28th. The lowest extent year ever, 2016, by the same date, was still in refreeze, at 100%.

Annual Average Sea Ice Volume
2018 was the 5th lowest calendar year on record for annual average sea ice volume in the Arctic. After 2017, 2012, 2016 & 2011. Since New Year we’ve climbed further up, and by early March it seems likely we’ll go beyond the 14 mark for the first time since November 2016, by averaging higher than …
Second 1–Week Melt in the Arctic
February 19th to 26th saw the second 1–week melt or compaction of sea ice in the 2019 Arctic. That is, the sea ice extent reported by JAXA was lower than 7 days before for the second time this year, be it primarily due to wind or actual melting of ice. Arguably, every single day of …
Annual Average Sea Ice Extent
2018 was the 2nd lowest (start of the green graph) calendar year on record for annual average sea ice extent in the Arctic. After 2016, but before 2017. Since New Year we’ve climbed back up to 4th lowest, and per now it even seems likely we’ll leave this chart at the high end during March, …
