Since the mid 1970s, the go Arctic ice consume has lost an area the size of Texas and Arizona combined.

With a shorter anneal of sea ice, fall storms batter Alaskas Arctic coast as never before, causing corroding that threatens communities (Wohlforth 9). Arctic ice is get thinner, melting and rupturing. For example, the largest single cylinder block of ice in the Arctic, the cover Hunt Ice Shelf, had been round for 3,000 years bef ore it started pass in 2000. Within two yea! rs it had split all the way through and is at present breaking into pieces (Global Warming: The Silent Threat). How can...
