The first sea ice-free September could occur as early as the 2030s, the study found. Arctic sea ice has been declining for decades but has shrunk at an even faster rate in the past 20 years.
The Arctic has already lost about half of its sea ice, compared to the 1980s at the end of the summer. It is known that more warming has delayed ice formation, and resulted in thinner sea ice growth.
Every September, scientists measure the extent of Arctic sea ice at its seasonal minimum. This year, sea ice was the sixth-lowest in the 45 years since satellites began measuring; sea ice extents ...
The Arctic Ocean is the mass of water positioned approximately above latitude 65° N. Arctic Sea Ice refers to the area of the Arctic Ocean covered by ice. The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September.
This visual shows the Arctic sea ice change and the corresponding absorbed solar radiation change during June, July, and August from 2000 through 2014. The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The Arctic ice pack undergoes a regular seasonal cycle in which ice melts in spring and summer, reaches a minimum ...
Sea ice decline refers to the melting of sea ice in the polar regions: In the Arctic: Arctic sea ice decline; In the Antarctic: Antarctica#Glaciers and floating ice and Antarctic sea ice#Recent trends and climate change
Arctic sea routes are increasingly being used for connecting major economies across the Pacific and Atlantic Oceans as global warming shrinks ice packs and allows for longer ice-free periods at sea.
Variation of Arctic sea ice from 1984 to 2019. Younger ice (first-year ice) is shown in darker shades, while older ice (four-year or older) is shown in white. Housed in the western part of the Arctic Ocean is the Beaufort Gyre, whose growing reservoir of freshwater is shrouded in mystery. In recent years, this increasing freshwater content (FWC ...
