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

2014-06-03 16:47:00| Climate Ark Climate Change & Global Warming Newsfeed

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),...

Ancient soils found to contain significant amounts of carbon

2014-05-28 16:30:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Soils that formed on Earth's surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet's carbon cycle. The finding, reported in the journal Nature Geoscience, is significant as it suggests that deep soils can contain long-buried stocks of organic carbon which could, through erosion, agriculture, deforestation, mining and other human activities, contribute to global climate change. "There...

There Is a Whole Lot of Carbon in Deep, Ancient Soils

2014-05-26 15:21:00| Climate Ark Climate Change & Global Warming Newsfeed

Softpedia: Researchers warn carbon in deep, ancient soils might become a contributor to climate change and global warming In a paper published in the journal Nature Geoscience this May 26, a team of researchers say that, according to evidence at hand, chances are that there is quite a lot of carbon trapped in deep, ancient soils. Besides, the team of specialists warns that, all things considered, it is possible that this carbon will one day become a contributor to ongoing phenomena such as climate change...

Agriculture, Mining Releases Carbon Trapped in Ancient Soils, Researchers Say

2014-05-26 11:02:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World: University of Wisconsin-Madison researchers said that ancient soils store large amounts of trapped carbon. The carbon from this soil, which is now being released due to erosion, agriculture and mining could contribute to climate change, researchers said. "There is a lot of carbon at depths where nobody is measuring," said Erika Marin-Spiotta, a University of Wisconsin-Madison assistant professor of geography and the lead author of the new study. "It was assumed that there was little carbon...
