How Acidification, Overfishing and Plastics Threaten the Worlds Oceans
2014-06-04 01:39:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: June 8 is World Oceans Day. Its a fitting time to contemplate humanitys evolving relationship with the source of all life. For much of human history, weve affected marine ecosystems primarily by what weve taken out of the seas. The challenge as we encounter warming temperatures and increasing industrial activity will be to manage what we put into them. As a top predator, humans from the tropics to the poles have harvested all forms of marine life, from the smallest shrimp to the largest whales,...

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),...

Ocean Acidification Chipping Away at Snail Shells
2014-05-02 15:52:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: Ocean acidification isn't proceeding at a snail's pace, says new research. The study finds that corrosive water off the U.S. West Coast is dissolving the shells of a marine snail, also known as a sea butterfly, that is a key player in the coastal food chain. Researchers worry that the mollusks' weakened shells could have far-reaching consequences for the animals that eat them, such as fish and marine mammals. Salmon, herring, and other commercially important species rely on a snail-rich...

Ocean Acidification Could Make Fish Lose Their Fear Of Predators, Study Finds
2014-04-14 12:19:00| Climate Ark Climate Change & Global Warming Newsfeed
ThinkProgress: Add "losing fear of predators" to the long list of impacts acidifying oceans could have on fish and other marine life. A new study published in Nature Climate Change has found that elevated CO2 levels in marine waters make reef fish attracted to the smell of their predators, rather than being repelled. Researchers looked at multiple species of reef fish living near natural volcanic CO2 seeps in Papua New Guinea, an environment the study says is acidified to levels comparable to projections of...
