Semimonthly BOE evaluation.
As of May 31st, extent is 10,834,476 km2. With on average 105 days to go until the end of the melt season on September 13th, we now require a daily drop of -93,662 km2 for a BOE to occur. (See Attachment 1).
Total extent loss so far this season is -3,613,165 km2. This has resulted in the current average daily drop of -40,597 km2. Since the year 2007, this is the 4th highest average daily loss from maximum to April 30th (2007-2020). (See Attachment 2).
Total extent loss from maximum is 1st highest on record since 2007, knocking 2016 from lead in this metric. (See Attachment 3).
Looking only at the month of May, 2020 lost -1,792,544 km2, nearly 200,000 km2 more than the 2007-2019 average. This is the 2nd largest loss since 2007, behind only 2010. (See Attachment 4).
