As Arctic Ocean ice disappears, the global climate impacts intensify

Yale Environment 360: The news last week that summer ice covering the Arctic Ocean was tied for the second-lowest extent on record is a sobering reminder that the planet is swiftly heading toward a largely ice-free Arctic in the warmer months, possibly as early as 2020. Peter Wadhams, professor emeritus of ocean physics at Cambridge University, is a sea ice specialist with 46 years of research on sea ice and ocean processes in the Arctic and Antarctic. In more than 50 expeditions to both polar regions, he has worked...

Arctic Ocean methane does not reach the atmosphere
2016-05-30 04:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: 250 methane flares release the climate gas methane from the seabed and into the Arctic Ocean. During the summer months this leads to an increased methane concentration in the ocean. But surprisingly, very little of the climate gas rising up through the sea reaches the atmosphere. "Our results are exciting and controversial," says senior scientist Cathrine Lund Myhre from NILU -- Norwegian Institute for Air Research, who is cooperating with CAGE through MOCA project. The results were published...

Guardian: Rick Spinrad, chief scientist at the National Oceanic and Atmospheric Administration (Noaa), announces global warming in the Arctic circle has hit new heights in the past year. Stating that warming is happening more than twice as fast in the Arctic than in the rest of the world, Spinrad says the average air temperature reached 1.3C above its usual level, the highest since observations began
Plastic Trash Found Arctic Ocean, Likely Forming Sixth Garbage Patch

EcoWatch: Not even the Arctic Ocean is safe from marine pollution. In a study published last week in the journal Polar Biology, researchers from the Alfred Wegener Institute for Polar and Marine Research (AWI) in Germany found marine litter on the surface of Arctic waters. #Plastic #litter makes its way north to the #ArcticOcean: https://t.co/9Bjy4EofNI pic.twitter.com/rmBP7lLaE4 -- Green Atom (@greenatomnet) October 23, 2015 It was the first litter survey conducted north of the Arctic Circle, and...

Arctic Ocean acidifies, threaten food web and major fisheries
2015-07-14 17:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: One byproduct of rising carbon-dioxide levels is increasing ocean acidity -- a phenomenon that scientists have termed an existential threat to marine life. The waters of the Arctic and the far-north Pacific are particularly prone to acidification as a result of several natural factors, so scientists regard the region as the proverbial canary in the coal mine for the rest of the world's oceans. A new study shows that within just fifteen years these waters may be too acidic for a range of marine animals...
