The Grim Reefer sends this news from an Associated Press report: "The Arctic isn't nearly as bright and white as it used to be because of more ice melting in the ocean, and that's turning out to be a global problem, a new study says. With more dark, open water in the summer, less of the sun's heat is reflected back into space. So the entire Earth is absorbing more heat than expected, according to a study (abstract) published Monday in the Proceedings of the National Academy of Sciences. That extra absorbed energy is so big that it measures about one-quarter of the entire heat-trapping effect of carbon dioxide, said the study's lead author, Ian Eisenman, a climate scientist at the Scripps Institution of Oceanography in California. The Arctic grew 8 per cent darker between 1979 and 2011, Eisenman found, measuring how much sunlight is reflected back into space." The same decrease in ice contributes to the weather circumstances that led to extremely low temperatures across parts of the United States this winter.
