Sea ice is growing again

After shrinking to its smallest summer extent in modern times, the pack ice of the Arctic Ocean has slowly begun to refreeze. By the end of November, the new ice and floes had grown enough to cover an estimated 3.9 million square miles, reports Far North Science.

In September where scientist pressed the alarm bottom the Sea Ice covered an area on  about 1.59 million square miles. At the same time the scientists announced that the North West Passage was open for sailing.

Over the past two months, the frozen world has almost doubled. The Arctic's November ice no longer sizzles in record territory: 2006 had slightly less ice cover. But this is not a reason to relax. The world should still be aware of the dangers of global warming, says Far North Science.

It should be severely noticed that November 2007 extent covers only 90 percent of the 4.3 million square miles normally covered by this time of year, based on the 1971-2000 mean.
