Problems in Polar Climate
Problems in Polar climate
Now that our earth has warmed approximately 1°F
in the last 50 years, there were some effect, some are these; according to the
National Assessment Synthesis Team, Alaska has warmed about 4°F.
Ice and Glaciers
There was this record when the amount of Arctic sea ice in
September 2005 (an area twice the size of Texas) has melted. Between 1961 and
1998, Alaska lost over 588 billion cubic yards of ice mass. In south Alaska,
the amount of ice surface decreased over 95%. In 52 years time, as much as 640
m (about 2.100 feet) glaciers were thinning.
Animals
It’s whether on ice, water, or either land, animals in
Alaska, have experienced due to the global warming. Polar bears survive on sea
ice, including resting, feeding, and mating. Polar bears have experience less
sea ice for their habitat. The amount of polar bears populations were estimated
as high as 5.000 bears, then 1.800, and now it’s believed to be 1.526 bears.
