Earth's Dwindling Arctic Sea Ice

A news article in Science last week (Science Mar. 27, p. 1655) suggests that polar ice may disappear entirely from the Arctic Ocean during the summer in less than 30 years. According to the article, scientists narrowed 23 different climate models down to the six that best fit the data for the ups and downs of sea ice from winter to summer in the past. They then used the models to predict when the summer ice would disappear completely from the Arctic Ocean. The best estimate is somewhere around 2037.

You may live to see polar bears become nearly extinct in the wild. On the bright side (if there is one), marine shipping could occur between the Atlantic and Pacific Oceans through the Arctic Ocean during the summer months.
