July's extent loss was 209% of June's, something pretty much unheard of in the satellite record. Average ratio over the past ten seasons is 142%, with a low of 93% (2010) and a high of 179% (2004). Not that that really means much; this year's July/June loss ratio is only so lopsided because June's loss was one of the very lowest on record. In fact, total extent loss last month was smaller than those recorded in 2007, 2009, 2012, and 2013. IOW, it was right around the median.
For the MJJA period-to-date, 2015 loss trails 2013, 2011, 2009, 2007, 2010, and 2012.
