Arctic Ocean to be ice-free during summers before 2050

Mother Nature Network: By the time today's babies graduate college, there's a very good chance they could celebrate with a cruise across the North Pole. That's according to the latest study on Arctic summer sea ice, the frozen pack that lingers through the Northern Hemisphere summer. In past decades, there's been less summer ice, and it's growing thinner. The research, published online Feb. 21 in the journal Geophysical Research Letters, says major sea ice loss could come within a decade or two, though some ice will...

Arctic nearly free of summer sea ice during first half of 21st century

ScienceDaily: For scientists studying summer sea ice in the Arctic, it's not a question of "if" there will be nearly ice-free summers, but "when." And two scientists say that "when" is sooner than many thought -- before 2050 and possibly within the next decade or two. James Overland of NOAA's Pacific Marine Environmental Laboratory and Muyin Wang of the NOAA Joint Institute for the Study of Atmosphere and Ocean at the University of Washington, looked at three methods of predicting when the Arctic will be nearly...
Study: Arctic Summers Warmest in 600 Years

Climate Central: The Arctic has seen warmer summers over the past two decades than at any time in the past 600 years, according to a study published this week in the journal Nature. The study uses a sophisticated statistical approach, known as Bayesian modeling, to show that the extremely warm summers in high northern latitudes are evidence of an overall warming trend, rather than just a temporary fluctuation in an otherwise unchanging climate. Thats a crucial distinction: a natural fluctuation might reverse before...

Climate Change Seen Leaving Arctic Ice-Free by 2050
2013-04-12 18:12:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: The Earths northern polar region will be almost ice-free in the warmest months by 2050, sooner than previously estimated, according to a study by two federal government scientists who work on climate change. The researchers from the National Oceanic and Atmospheric Administration used three separate methods to predict the sea- ice trends in the Arctic Ocean, and their estimates for 2020 to 2060 forecast elimination of most ice during the Northern Hemispheres warmest months, according to a statement....
