JAXA GLOBAL SEA ICE EXTENT : 16,943,034 km2 as at 3 February 2020
3 days ago, I wrote..
Recently, mostly above average Arctic sea ice extent daily gains, and mostly below average Antarctic sea ice extent daily loss leading to recent days of extent gain. It is therefore possible that minimum was reached on the 29 January at sea ice extent of 17,046,068 km2, i.e 2 weeks earlier than the average of the last 10 years.
I was wrong. In the last 3 days Arctic Sea Ice gain has stalled, and Antarctic Sea Ice loss a bit above average. Predictions are a mug's game.
- On this day extent is 9th lowest in the satellite record since 1979,
- Extent LOSS on this day 55 k, 35 k MORE THAN the last 10 years' average loss of 20 k,
- Extent loss to date 7.66 million km2, 1.15 million (13.1%) less than the 10 year average of 8.81 million km2 by this day.
- Extent is 0.68 million km2 greater than 2006,
- Extent is 1.19 million km2 greater than 2017,
- Extent is 1.06 million km2 greater than 2018,
- Extent is 0.65 million km2 greater than 2019,
- Extent is just 9 k km2 greater than the 2010's average,
- 96.7% of the average ice loss of the season done, with on average 9 days to the average minimum date of 12 Feb.
The Perils of Projections
Average melt from this date would produce a minimum of 16.64 million km2, 1.09 million more than the record low in early 2018.
