Ocean Acidification Rate 10 Times Faster than Ancient Upheaval
2014-06-03 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: These days the ocean is acidifying at a rate 10 times faster than it did during a similar upheaval 56 million years ago. During those ancient days, researchers estimate that ocean acidity increased by about 100 percent in a few thousand years or more, and levels didn't bounce back to normal for another 70,000 years. Some species were able to adapt and evolve to such radical environmental changes, while others perished and died off. Also during this time, a wave of carbon dioxide (CO2) surged into...
Current rate ocean acidification eclipses ancient extinction event

Blue and Green: The acidification of the worlds oceans, occurring today because of manmade carbon emissions, is happening 10 times faster than it did 56 million years ago, when many species were wiped out as a result. Around 9 million years after the extinction of the dinosaurs, between the Paleocene and Eocene epochs, a mysterious climate event caused global temperatures to soar and killed off many forms of marine life. Scientists are uncertain of the causes of the PaleoceneEocene Thermal Maximum (PETM),...

Southern Ocean Research Provides New Insight Into Ice Age Climates
2014-06-03 13:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth`s climate history during which the northern continents were covered by ice sheets, according to new research appearing in the Proceedings of the National Academy of Sciences. Plankton fossils contained in deep-sea sediments contain chemical traces that reveal rearranged ocean water masses, as well as extended sea ice coverage off Antarctica, during the...

Solving puzzle ice age climates: Southern Ocean & explanation for 'Last Glacial Maximum'
2014-06-03 12:45:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The paleoclimate record for the last ice age -- a time 21,000 years ago called the "Last Glacial Maximum" (LGM) -- tells of a cold Earth whose northern continents were covered by vast ice sheets. Chemical traces from plankton fossils in deep-sea sediments reveal rearranged ocean water masses, as well as extended sea ice coverage off Antarctica. Air bubbles in ice cores show that carbon dioxide in the atmosphere was far below levels seen before the Industrial Revolution. While ice ages are set...
