Wind-blown Antarctic sea ice helps drive ocean circulation
2016-06-27 10:14:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: A team of scientists used a computer model to synthesize millions of ocean and ice observations collected over six years near Antarctica, and estimated, for the first time, the influence of sea ice, glacier ice, precipitation and heating on ocean overturning circulation. Overturning circulation brings deep water and nutrients up to the surface, carries surface water down, and distributes heat and helps store carbon dioxide as it flows through the world's oceans, making it an important force in the...
Antarctic carbon dioxide reaches highest levels in 4 million years
2016-06-18 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Monitor: Antarctica recently witnessed an event that last took place four million years ago: Carbon dioxide levels broke through the barrier of 400 parts per million (ppm). In fact, the frozen continent is a laggard in this respect. The announcement Wednesday by the National Oceanic and Atmospheric Administration (NOAA) gave the date of this milestone as May 23. But the global annual mean concentration of carbon dioxide already surpassed 400 ppm last year, the first time that has happened in human history....

Antarctic CO2 hits 400ppm for first time in 4m years
2016-06-16 11:48:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Were officially living in a new world. Carbon dioxide has been steadily rising since the start of the Industrial Revolution, setting a new high year after year. Theres a notable new entry to the record books. The last station on Earth without a 400 parts per million (ppm) reading has reached it. A little 400 ppm history. Three years ago, the worlds gold standard carbon dioxide observatory passed the symbolic threshold of 400 ppm. Other observing stations have steadily reached that threshold...

Antarctic coastline images reveal four decades of ice loss to ocean
2016-06-05 00:19:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: A study of images along 2000km of West Antarctica's coastline has shown the loss of about 1000km2 of ice - an area equivalent to the city of Berlin - over the past 40 years. Researchers were surprised to find that the region has been losing ice for such a length of time. Their findings will help improve estimates of global sea level rise caused by ice melt. A research team from the University of Edinburgh analysed hundreds of satellite photographs of the ice margin captured by NASA, the United...
