The effects of global warming in the Arctic include rising temperatures, loss of sea ice, and melting of the Greenland ice sheet. Potential methane release from the region, in particular through the thawing of permafrost and methane clathrates, is also a concern. Because of the amplified response of the Arctic to global warming, it is often seen as a leading indicator of global warming. According to the Intergovernmental Panel on Climate Change, “warming in the Arctic, as indicated by daily maximum and minimum temperatures, has been as great as in any other part of the world. The period of 1995-2005 was the hottest decade in the Arctic since at least the 17th hundred, with temperatures 2 °C (3.6 °F) above the 1951-1990 average. Some areas within the Arctic have warmed even further rapidly causing changes, with Alaska and western Canada’s temperature rising by 3 to 4 °C (5.40 to 7.20 °F).This warming has been made not only by the increase in greenhouse gas concentration but also the deposition of soot on Arctic ice. A 2013 article published in Geophysical Research Letters has revealed that temperatures in the region must be as high as they currently are because at minimum 44,000 years ago and possibly as long as 120,000 years ago. The writers conclude that “anthropogenic increases in greenhouse gasses have led to unprecedented regional warmth.The poles of the Earth are more sensitive to any change in the planet’s climate than the rest of the world. In the face of continuous global warming, the poles are heating faster than lower latitudes. The primary cause of this phenomenon is ice-albedo feedback, whereby melting ice uncovers darker land or ocean beneath, which then absorbs more sunlight, causing more heating. The destruction of the Arctic sea ice may signify a tipping point in global warming when uncontrolled climate change begins, but on this stage, the science is not yet settled.Sea ice is currently in deterioration in the area, extent, and volume and will cease to exist someday during the 21st century. Sea ice area relates to the total area covered by ice, while sea ice extent is the area of ocean with in the least 15% sea ice, while the volume is the total mass of ice in the Arctic.People are changing the geographic space of the Arctic, and the Arctic is altering the population. Much of the climate change in the Arctic can be attributed to women influences on the atmosphere, such as an enhanced greenhouse effect caused by the increase in CO2 due to the burning of fossil fuels. Climate Change is having a direct bearing on the people that live in the Arctic, as well as other societies around the world. The warming environment offers difficulties to local communities such as the Inuit. Hunting, which is a major way of continuance for some small communities, will be changed with increasing temperatures. This has lead to many problems like the movement of animals and supplies by trucks over large distances even wouldn’t work in this kind of situation.
The reduction of sea ice will cause certain species populations to decline or even become extinct. In good years, some towns are fully employed by the economic harvest of certain animals.The harvest of many animals fluctuates each year including with the increase of temperatures; it is likely to continue changing and creating issues for Inuit hunters. Unsuspected fluctuations in river and snow situations will cause herds of animals, including reindeer, to change migration patterns, calving spots, and forage availability. Other forms of transportation in the Arctic have seen negative impacts from the current warming, with some transportation routes and pipelines on land being disrupted by the melting of ice. Many Arctic communities depend on frozen roadways to transport supplies and journey from area to area.The changing landscape and unpredictability of weather are creating new challenges in the Arctic.
