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 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.
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
The Arctic Ocean's ability to absorb carbon dioxide from the atmosphere appears to be waning due to melting permafrost and worsening coastal erosion. Arctic ocean may absorb less CO2 than ...
Countries within the Arctic Region. In 2008, following increased media attention for the Arctic, the five countries adjacent to the Arctic Ocean (Canada, Denmark (Greenland), Norway, Russia and the United States) published the Ilulissat Declaration. This proclaims the Arctic states' responsibility to protect the ecosystem of the Arctic Ocean. [3]
Millions of Americans should prepare for an Arctic blast that will blanket much of the country in below-freezing temperatures over the next several days. Frigid conditions are expected over a ...
Whilst the Arctic region is one of many natural sources of the greenhouse gas methane, there is nowadays also a human component to this due to the effects of climate change. [2] In the Arctic, the main human-influenced sources of methane are thawing permafrost, Arctic sea ice melting, clathrate breakdown and Greenland ice sheet melting.
The probes are aimed at providing more accurate data gauging the rate at which warming ocean water around Antarctica is melting the continent's coastal ice, allowing scientists to improve computer ...
