If you want a story about record low Arctic sea ice then forget it!
The Arctic sea ice has gain proved far more resilient than forecast and has refused to produce a record low minimum in 2019.

Will it slide like in 2012?
The big question is will the Arctic sea extent slide away like it did in the summer of 2012 or take a shallower trajectory?
Arctic sea ice close to historic low for early June
Arctic sea ice extent is second lowest behind 2016 for early June, but 2012 is the year to watch.
Polar sea ice extent since 1990
I have always thought that following sea ice extent using daily SII values from the NSIDC was not a good idea. Even following weekly, monthly or seasonal extremes didn’t seem to simplify the ‘noise’ that you got with line graph or bar chart. That’s why in my opinion a graph of moving 365 day average sea ice extents is ideal at looking at the long term trend in the last 30 years. The Arctic has most people must now realise has seen a steady decline since 1990, although in the last year the 365 day average has recovered somewhat, although...
