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.
Records are falling at the top of the world. The Arctic summer has a long way to go, but already sea ice levels over great swathes of the sprawling Arctic ocean are at historic lows (in the 40 ...
The increasingly concerning consequences of climate change in the Arctic, resulting in melting Arctic sea ice, have become ground for enhanced attention and cooperation in the region. Fear of economic exploitation and pollution in the Arctic Ocean was a key source of momentum in drafting and implementing the Ilulissat Declaration. [ 3 ]
The dark ocean surface reflects only 6 percent of incoming solar radiation, while sea ice reflects 50 to 70 percent. [32] The Arctic was historically described as warming twice as fast as the global average, [33] but this estimate was based on older observations

Arctic sea ice has been monitored by satellites since 1979, [8] and has been recorded to be melting away every decade. [9] [10] The ice sheets are becoming thinner and younger, indicating increasing fragility. [11] The major threats are emissions from greenhouse gases and fossil fuels that are primary causes of global warming.
