Emissions of CO2 driving rapid oceans 'acid trip'

The world's oceans are becoming acidic at an "unprecedented rate" and may be souring more rapidly than at any time in the past 300 million years.

In their strongest statement yet on the issue, scientists say acidification could increase by 170% by 2100.

The report's co-author said acidification had already caused a 30% loss of species in some ocean ecosystems.

The researchers conclude that human emissions of CO2 are clearly to blame.

The study will be presented at global climate talks in Poland next week. ... Read more about Emissions of CO2 driving rapid oceans 'acid trip'

OSLO, Oct 3 (Reuters) - The world's oceans are under greater threat than previously believed from a "deadly trio" of global warming, declining oxygen levels and acidification, an international study said on Thursday.

The oceans have continued to warm, pushing many commercial fish stocks towards the poles and raising the risk of extinction for some marine species, despite a slower pace of temperature rises in the atmosphere this century, it said. ...
