In the first week of September, sea ice extent took a sharp downward turn, exceeding the pace of decline for any previous year during that period, and placing the 2020 sea ice minimum firmly as second lowest—after 2012—in the 42-year continuo

The concentration of mercury in fish in Alaska’s Yukon River may exceed EPA mercury criterion by 2050 if greenhouse gas emissions that cause global warming are not constrained, according to new scientific research led by the National Snow and Ice

After a period of rapid sea ice loss extending into the last week of August, the rate has slowed with the onset of autumn in the Arctic. A region of low concentration ice persists in the Beaufort Sea.

While the Arctic summer is waning, sea ice extent continues to drop. In early August, ice-free pockets began to develop in the Beaufort and Chukchi Seas and expanded steadily through the first half of the month.

The fast pace of ice loss observed in the beginning of July continued through the third week of July, after which the ice loss rates slowed dramatically.
