2019 Arctic Sea Ice Minimum Is Second LowestThis photo, taken during an Operation IceBridge flight on September 9, 2019, shows an opening in the sea ice cover north of Greenland. The lead is partially filled by much smaller sea ice rubble and floes. Unlike 2012—when a powerful August cyclone smashed the ice cover and accelerated its decline to the lowest ice extent on record—this melt season did not bring any extreme weather events. Although areas within the Arctic Circle saw average temperatures 4 to 5 degrees Celsius (7 to 9 degrees Fahrenheit) above normal, events such as the severe Arctic wildfire season and the European heat wave did not have much impact on sea ice melting.
