Sea ice closing in on record

Bad news for those who still think it'll be 20 or 30 years before we have to face an ice-free arctic ocean. Climate change is accelerating far faster than anything in the models.

More ominous signs Wednesday have scientists saying that a global warming "tipping point" in the Arctic seems to be happening before their eyes: The National Snow and Ice Data Center reported that sea ice in the Arctic now covers about 2.03 million square miles. The lowest point since satellite measurements began in 1979 was 1.65 million square miles set last September...

Within "five to less than 10 years," the Arctic could be free of sea ice in the summer, said NASA ice scientist Jay Zwally.

"It also means that climate warming is also coming larger and faster than the models are predicting and nobody's really taken into account that change yet," he said
