A new study shows that the magnitude of surface darkening in the Arctic (due to the retreat of sea ice) is twice as large as that found in previous studies.
The retreat of sea ice in the Arctic Ocean is diminishing Earth's albedo, or reflectivity, by an amount considerably larger than previously estimated, according to a new study that uses data from instruments that fly aboard several NASA satellites.
I am very well aware and have previously blogged that there are multiple factors that determine the degree of ice lost any given year — but the literature is clear that even in 2007, global warming played «a large part» (see «What drove the dramatic retreat of arctic sea ice during summer 2007?
Even with the increasing summer retreats of sea ice, which climate scientists say are being driven in large part by global warming caused by humans....
Even with the increasing summer retreats of sea ice, which polar scientists say probably are being driven in large part by global warming caused by humans....
A large polar bear, stuck ashore, approached biologists studying coastal erosion related to sea - ice retreats.
Recent estimates indicate that the Antarctic sea ice cover is expanding at a statistically significant rate with a magnitude one - third as large as the rapid rate of sea ice retreat in the Arctic.
Marine ice sheet instability occurs when sub-shelf melt rate is large enough to force the ice sheet grounding line to retreat into an area where the ice is grounded below sea level on an inward - sloping bedrock, then it can become unstable.
As the sea ice retreats, the Arctic's fossil treasures are eyed greedily by large corporations and nations bordering the Arctic Ocean.
The albedo change resulting from the snowline retreat on land is similarly large as the retreat of sea ice, so the combined impact could be well over 2 W / sq m. To put this in context, albedo changes in the Arctic alone could more than double the net radiative forcing resulting from the emissions caused by all people of the world, estimated by the IPCC to be 1.6 W / sq m in 2007 and 2.29 W / sq m in 2013.»
This has never happened before because the sea ice never retreated very much in the summer and the water temperature could not rise above zero because of the ice cover... The permafrost is acting as a cap for a very large amount of methane (CH4), which is sitting in the sediments underneath in the form of methane hydrates.
As they warm and as the sea ice retreats, larger areas are freed for invasion by major blooms of algae and other microbes.
He noted the first week of October in 2015 had a large net increase of sea ice after an extended retreat.
Thus, when sea ice is retreating or advancing at a high rate over the course of the month, as was the case for December 2016, the Sea Ice Index monthly average can yield a larger extent than from simply averaging daily extent valusea ice is retreating or advancing at a high rate over the course of the month, as was the case for December 2016, the Sea Ice Index monthly average can yield a larger extent than from simply averaging daily extent valuice is retreating or advancing at a high rate over the course of the month, as was the case for December 2016, the Sea Ice Index monthly average can yield a larger extent than from simply averaging daily extent valuSea Ice Index monthly average can yield a larger extent than from simply averaging daily extent valuIce Index monthly average can yield a larger extent than from simply averaging daily extent values.
Walrus depend on sea ice as a platform for giving birth, nursing, and resting between dives to the seafloor, where they feed.46 In recent years, when summer sea ice in the Chukchi Sea retreated over waters that were too deep for walrus to feed, 47,48 large numbers of walrus abandoned the ice and came ashosea ice as a platform for giving birth, nursing, and resting between dives to the seafloor, where they feed.46 In recent years, when summer sea ice in the Chukchi Sea retreated over waters that were too deep for walrus to feed, 47,48 large numbers of walrus abandoned the ice and came ashosea ice in the Chukchi Sea retreated over waters that were too deep for walrus to feed, 47,48 large numbers of walrus abandoned the ice and came ashoSea retreated over waters that were too deep for walrus to feed, 47,48 large numbers of walrus abandoned the ice and came ashore.
This overshoot is caused predominantly by the reduction of the meltwater in the northern North Atlantic associated with the retreat of the large amount of sea ice, an effect that becomes dominant when the subpolar North Atlantic is covered by sea ice as in the glacial condition.
