This is up a mere 2 k to 53 k above the 2010-2017 average
note : 29k minor correction to total area - the pesky polar hole adjustment keeps on popping up.

Daily area loss 12th July at 2010's average. See how using 5 day trailing average disguises major daily changes. Loads of drama on the daily extent measures, partly reflected in 5 day extent average changes already.
The result is extent loss is catching up fast to area loss, as shown well on the attached graph. Will area losses also accelerate ?
