The year 2008 was mo only to 2007, the warmest year on record for the Arctic. Atmospheric temperatures in the Arctic are now 5 degrees Celsius (9 degrees Fahrenheit) greater than normal. overwinter and springtime temperatures remain relatively warm over the replete(p) Arctic, in contrast to the 20th century and consistent with an uphill global warming influence.
The oceans of the Arctic continue to warm, mainly as a result of the dramatic ocean deoxyephedrine lam which allows more solar energy to be absorbed by the oceans. More worryingly these changes were accompanied by an unprecedented send of sea level rise and in relation to the salinity of the Arctic region, in 2007 upper-ocean salinity structure and Atlantic weewee temperatures in the central Arctic Ocean moved out-of-door from climatologically norms, with increased salinity and temperature.
This highlights a general increase in permafrost temperatures in Alaska, Northwest Canada, Siberia and Northern Europe. This could micturate a macro impact on global warming as, according to Chapter 6 of Terrestrial Ecosystems in a Changing World, by JG Canadell et al, produce by Springer-Verlag in 2007, permafrost traps over 400 billion slews of carbon in the soil.
The warming temperature and the loss of sea ice impacts heavily on marine life in the Arctic region. The polar bear, walrus, caribou, and beluga whale and reindeer populations as beingness particularly at risk of the environmental changes taking place.
dapple melt of sea ice in the Arctic would have a marginal effect on sea levels, melting of the ice shelf in Greenland would have dramatic sea level effects. Greenlands largest glacier, among a majority of others, continued its retreat. The ice sail lost at least 100 cubic km (24 cubic miles) of ice, making it one of the largest single contributors to global sea level rise.
The Arctic Report Card 2008 shows how close the satellite is to...If you want to get a full essay, order it on our website: Orderessay
