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
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. Now the worm has turned, and explicitly suggested in a dotted way below, is the possibility of a new record low for the full calendar year. Of course, as …
Arctic sea ice volume refreeze
Arctic sea ice volume refreeze has come 99% of the way since Summer Minimum per March 31st. The lowest volume year ever, 2017, by the same date, was at 87%.
