The Variability of Arctic Sea Ice Extent from Spring to Summer and Its Linkage to the Decline of SIE in September
The satellite record analysis for monthly differences of Arctic sea ice extent (SIE) shows that the most significant accelerated monthly sea ice reduction occurred between June and July although, on average, the largest sea ice reduction occurred between July and August. The monthly difference of Ju...
