Recent NASA photos showed the opening of the Northwest Passage
Researchers were astounded when, in the fall of 2007, they discovered that the year-round ice pack in the Arctic Ocean had lost some 20 percent of its mass in just two years, setting a new record low since satellite imagery began documenting the terrain in 1978. Without action to stave off climate change, some scientists believe that, at that rate, all of the year-round ice in the Arctic could be gone by as early as 2030.
