As a couple of readers have already mentioned, sea ice extent according to IARC/JAXA has reached a new record low value. Sea ice extent according to NSIDC is “knockin’ on the door.”
The mean date of daily minimum extent in the IARC/JAXA data is Sep. 15.5, the earliest is Sep. 9 and the latest Sep. 24. So we can expect *about* 3 more weeks before the actual minimum is reached.
And we’ve already broken the record minimum for sea ice area. It’s looking more and more like this year will break the records for sea ice area, extent, and volume. For more information (including more broken records of specific data sets), see Neven’s excellent sea ice blog.
