Southern Hemisphere ocean warming 'underestimated'
2014-10-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: Hidden heat Previous estimates of global ocean warming have been significantly underestimated due to historically sparse temperature data from the Southern Ocean, new research has found. The study, led by Australian oceanographer Dr Paul Durack from the US Department of Energy's Lawrence Livermore National Laboratory, was published online today in Nature Climate Change.. They analysed satellite observations of sea surface height changes along with ocean temperature data collected between 1970...

Warming of Southern Hemisphere oceans underestimated
2014-10-07 04:17:00| Climate Ark Climate Change & Global Warming Newsfeed
Asia News International: Scientists have revealed that until recent improvements occurred in the observational system in the early 21st century, Southern Hemisphere ocean heat content changes were likely underestimated. Lawrence Livermore scientists used a fleet of miniature research vessels (Argo), the global flotilla of more than 3,600 robotic profiling floats, that point towards heating of the upper layers of the world's ocean currents. The team found that the 3,600 Argo floats currently observing the global oceans,...

Lack of ocean heat puzzles NASA hunt for warming 'hiatus'
2014-10-06 22:20:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: The deep ocean may not be hiding heat after all, raising new questions about why global warming appears to have slowed in recent years, said the US space agency Monday. Scientists have noticed that while greenhouse gases have continued to mount in the first part of the 21st century, global average surface air temperatures have stopped rising along with them, said NASA. Some studies have suggested that heat is being absorbed temporarily by the deep seas, and that this so-called global warming...
Ocean Warming in Southern Hemisphere Worse Than We Thought
2014-10-06 20:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: in the Southern Hemisphere, which make up 60 percent of the world's oceans, are warming far worse than previously thought, according to a new study. Using satellite observations and a large collection of climate models, Lawrence Livermore National Laboratory (LLNL) scientists have found that long-term ocean warming in the upper 700 meters (~2,300 feet) of Southern Hemisphere oceans has likely been underestimated. "This underestimation is a result of poor sampling prior to the last decade and...

Scientists Discover Worlds Oceans Warming Faster Than Predicted
2014-10-06 16:10:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: The oceans are warming faster than previously thought, according to a pair of new studies released this weekend and published in the scientific journal Natural Climate Change. This conclusion is largely due to enhanced information gathering in the southern oceans, which was limited in the past. The research teams compared previous ocean warming figures, based on the less complete data, with projections based on information they were able to obtain from more detailed studies. They found that from...
