Into the Blue Again

Arctic sea ice extent is lowest on record for the date. Meanwhile, the much more important data for sea ice volume can be seen in this zoomed out 10–year chart: Please help share this most important graph revealing persistent decline and a climate Tipping Point several decades back in our past: The true Tipping Point […]

Arctic sea ice extent meltdown

Arctic sea ice extent meltdown has come 5% of the way from Winter Maximum to a Blue Ocean Event per March 29th. The lowest extent year ever, 2016, by the same date, was at 2%.

½ Year Arctic Blue Ocean Estimates

Our first ½ year long Arctic Blue Ocean Event could come as early as 2023. No sea ice for 6 months, in as little as 4 years?

Year-To-Date Average Sea Ice Volume

The average for the year for Arctic sea ice volume is now 7th lowest on record per March 27th. These are however still early days, and a 86–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 150–day or 200–day […]

Year-To-Date Average Sea Ice Extent

The Year–To–Date average extent is still 6th lowest for sea ice in the Arctic, but the YTD graph seems likely to peak record early this year, and maybe even before April. It peaks when today’s extent is lower than the average so far this year. Q: Where’s the data source for this plot?A: Here: https://ads.nipr.ac.jp/vishop/#/extentQ: […]

Annual Average Sea Ice Volume

Since New Year we’ve climbed from 5th lowest annual average sea ice volume on record in the Arctic to a likely 6th lowest by April, and in early March we went beyond the 14 mark for the first time since November 2016, by averaging higher than 14 thousand km³ sea ice volume. Q: Where’s the […]

Annual Average Sea Ice Extent

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 in early March we went beyond the 10 mark for the first time since June 2016, by averaging higher than 10 million km² sea ice extent. Q: Where’s the data source […]

Arctic sea ice volume refreeze

Arctic sea ice volume refreeze has come 99% of the way since Summer Minimum per March 23rd. The lowest volume year ever, 2017, by the same date, was at 85%. 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 […]
