Arctic sea ice / Re: The 2019 melting season

What's the official minimum then?

Currently, according to JAXA data, it is 4,158,349 km^2. Achieved on September 4th.

The extent data is misleading, at best.  The rank matters little - what matters is the sea ice thickness and the condition of the ice in general.

Unfortunately, the sea ice extent graphs are given the most attention rather than sea ice thickness and fragmentation (and sea surface temperature).

The sea ice extent is a dubious measurement, as highly fragmented slush should not be considered "extent", but it does seem to get included.  Therefore, the "extent" of the low quality single year ice of 2019 is compared against the "extent" of the multi year ice of, say 1995 - which is incorrect - it's comparing apples to oranges.

We need to be focusing on the multi year ice, sea ice thickness  - not the "extent" data.

On that note, how's that multi-year ice doing in 2019?

Record low:

Unlikely to impossible on July 17th.

Real possibility.  July 28th.
