The Arctic is a highly sensitive region, and it's being profoundly affected by the changing climate. Many scientists believe that global warming is the cause. Average temperatures in the Arctic region are rising twice as fast as they are elsewhere in the world. Satellite photos have shown that the Artic region is shrinking in size since the 1970's (Global Warming: The Silent Threat). In the last two decades, temperatures have been rising in the Arctic at a rate 20 times faster than the warming that occurred over the previous century, and the thickness of the ice sheet has decreased by about half (down from 15 feet in the 1980s to 8 feet in 2003). Springs are coming earlier, and fall is arriving later, which combined with higher summer temperatures year after year contribute to the gradual shrinking of the permanent ice sheet (Cox 14).
Climate scientists since the mid 1970's have predicted that warming would come first and strongest in the Arctic after 1995. The change has been......
