How global warming is melting the ice caps

The pencil eraser is a highly sensitive region, and its being fertile affected by the changing climate. Many scientists believe that global warm is the cause. Average temperatures in the Arctic region ar rising tw churl as fast as they atomic number 18 elsewhere in the world. Satellite photos fix shown that the Artic region is lessen in sizing since the 1970s (Global Warming: The unflustered Threat). In the brave two decades, temperatures wipe out been rising in the Arctic at a rate 20 multiplication faster than the warming that occurred over the previous century, and the thickness of the grouch sheet has rock-bottom by about half (down from 15 feet in the mid(prenominal)-eighties to 8 feet in 2003). Springs are coming earlier, and f completely is arriving later, which combine with higher summer temperatures year later year convey to the gradual shrinking of the permanent ice sheet (Cox 14). Climate scientists since the mid 1970s have predicted that warming woul d begin first and strongest in the Arctic after 1995. The change has been increasingly evident, both to scientists and to indigenous people. In Alaska and western Canada, winter temperatures have gone up as much as 7 degrees F over the noncurrent 50 years. Since the mid 1970s, the move Arctic ice consume has lost an area the size of Texas and Arizona combined.

With a shorter anneal of sea ice, fall storms switch Alaskas Arctic coast as never before, causing wear that threatens communities (Wohlforth 9). Arctic ice is get thinner, melting and rupturing. For example, the largest single ram of ice in the Arctic, the cover Hunt Ice Shelf, had been rough for 3,000 years before it star ted pass in 2000. Within two years it had s! plit all the way through and is instantaneously breaking into pieces (Global Warming: The Silent Threat). How can...
