Climate change: Arctic sea ice extent at new low


From The Denver Post (Bruce Finley):

The data show the area covered by sea ice shrank to 1.58 million square miles, its lowest ebb in 32 years. That’s about 27,000 square miles less than the previous low of 1.61 million square miles recorded Sept 18, 2007. Another 150,000 square miles of sea ice could melt before the middle of next month, when refreezing typically begins, NSIDC research scientist Walt Meier said, during a conference call with colleagues at NASA. The past six years have brought the six lowest levels of sea ice since 1979, when measurements began. The climate scientists said the melting will open shipping routes for energy companies hoping to claim untapped oil and gas, while also worsening climate change worldwide…

The dissolving of white sea ice into darker open water means reduced reflection. More sunlight is absorbed into oceans, raising water temperatures. This ocean warming is seen by some as related to climate change, affecting ocean currents, air currents and storm paths.
