Arctic Sea Ice News and Analysis
The article is about the scientific analysis of the conditions of the Arctic sea ice which provides information more frequently relative to the conditions at specified intervals of time. It also looks at the level of the Arctic sea ice in the previous years as compared to what is being experienced currently as to whether it is at its lowest or maximum(NSIDC, 1). There has been a constant increase in the level of ice in the Arctic sea ice in all sides of the sea; the Atlantic side and the Pacific side of the Arctic. Records from the satellite show Arctic sea ice attained its annual maximum level in March 2018. In the past four years, there occurred lowest maximum extents in the level of the sea ice.
The concentration of sea ice refers to the total area covered by the sea ice about its total at some particular specific location in the sea. It is usually used by climate scientists and nautical navigators as a variable. The percentage threshold used to delineate sea ice is extent usually is 15 percent.
The maximum sea ice extent occurs during lower temperatures with cold air experienced by the sea ice which increases the rate of freezing while the minimum sea ice extent occurs when there are slightly higher temperatures at sea with warm air blowing which causes ice to melt away.
The difference that was there between the 1979 and 2017 maximum sea ice extent is 14.48 million square kilometers while the minimum sea ice extent between 1979 and 2012 is 6.

75 million square kilometers. The ten years with the lowest maximum sea ice extents also exhibit the lowest minimum sea ice extents.
The Ice-Albedo Feedback is just a feedback climate process that is positive where alterations in the glaciers, sea ice, and caps normally affect the albedo. The sea ice measurement extent that I find to be closely connected to the Ice-Albedo Feedback is the maximum measurement extent. This is because Sea Ice climate has to be always cool with cool temperatures; factors which contribute to the normal environment as well as providing towards the maximum extent of the sea ice(NSIDC, 1).
The Antarctica sea ice extent on an annual basis is closely related to that of the Arctic because they both exhibit constant rates of increase in the extent of the sea ice (NSIDC, 1). Antarctica and the Arctic experience almost experience rapid growth of ice along the sidelines of the sea which leads to the sea ice expansion. Therefore both extents rely on the same factors for an increase of reduction, however; Antarctica has potential to experience more increased levels of sea ice extent than the Arctic.
An ice-free arctic in the very first place will impact trade in a way that it will provide a convenient network of navigation for ships which are mostly cruising the Arctic for business. When the ice melts, it will allow smooth passage of water vessels across the Arctic which will improve trade in the region between associated parties (NSIDC, 1). This will cause shallow surface ocean circulations because of the higher temperature of the sea due to warmer air. The latter will also affect the oil exploration and land rights because the reduction in sea ice usually renders oil exploration a dangerous exercise therefore in the event, it will eventually lead to changes in the land rights.
