On average, this is when daily area loss declines sharply But even so, the area loss of 18k is below this day's 2010's average by 9 k. Extent loss (also 5-day trailing average)) increased from 44k to 73k, above average for the day. And daily extent loss was 128k after 106k and 68k the days before..
It is all about the 4 central seas now. On the melting season thread there is evidence of strong ice loss along the Atlantic front and predictions of weather favourable for further ice loss. Will above average area losses return strongly in the last 30 days or so of the season ? Not seen for a good while. The area minus extent graph demonstrates how as far as area vs extent is concerned, this has not been an average year so far.
