Sea Ice in Its “Death Spiral”

After the ominous news that North American permafrost (and presumably European and Asian, as well) stores 60% more greenhouse gases than we thought, here’s another siren announcing that we are rushing full speed ahead towards a climatic tipping point:

Scientists are reporting that the extent of sea ice in the Arctic is at the second lowest point on record. Currently ice covers 2.03 million square miles; last year’s sea ice coverage, 1.59 million square miles, set the record. In the past ten years Arctic sea ice has declined 10 percent.
