Worst Case for Oceans: Another 'Great Dying'

Study blames Permian mass extinction on ocean acidity

(Newser) - The planet's greatest extinction —the Permian mass extinction, or the "Great Dying"—wiped out around 90% of marine species and two-thirds of those on land over 60,000 years. Some 252 million years later, researchers are explaining what happened—and it may not bode well for... More »

Oceans Careening Toward Mass Extinction

Thanks to a whole raft of issues 'unprecedented in Earth's known history'

(Newser) - Our oceans are in bad shape—so bad in fact, that a mass extinction may already be under way, thanks to a deadly intersection of global warming, declining oxygen, and acidification, plus overfishing and pollution, the Guardian and Reuters report. A new study from the International Program on the State... More »

X Prize's New $2M Task: Gauge Ocean Acidity

Latest X Prize contest could help save coral reefs

(Newser) - The latest X Prize is a big one with a pretty payout. The task? Find out how to measure ocean acidification and you could get close to $2 million for your trouble. You'll also have the added ego boost of helping the world better understand the process behind decaying... More »

CO2 Levels Are Super-Sizing Crabs

Crustaceans bulk up as carbon levels rise

(Newser) - Carbon emissions usually make news for their effect on the climate, but they're also having a major impact on marine ecosystems in the form of creating huge crustaceans, the Washington Post finds. In the Chesapeake Bay area and many others, oyster and scallop populations are dropping as crabs—who... More »

Oceans Acidifying at Highest Rate in 300M Years

Columbia researchers warn of dangers to marine life

(Newser) - Industrial emissions are causing the oceans to acidify at a fast rate—the fastest in 300 million years, say researchers from Columbia University. That could spell danger for sea creatures. In the last century alone, the pH of the oceans dropped by 0.1 units. That's 10 times faster... More »

Acidic Oceans Could Confuse Fish: Study

Global warming hiking up oceanic acidity levels

(Newser) - Climate change could be a disaster for marine life, a new study finds. As the atmosphere fills with CO2, the ocean absorbs it, and becomes more acidic, Wired reports, and clownfish, which navigate by scent, lose their ability to do so in water as acidic as the ocean is expected...
