The Variability of Arctic Sea Ice Extent from Spring to Summer and Its Linkage to the Decline of SIE in September
Thesatellite record analysis formonthly differences of Arctic sea ice extent (SIE) shows that themost significant acceleratedmonthly sea ice reduction occurred between June and July although, on average, the largest sea ice reduction occurred between July and August.
