Corals 'Could Survive a More Acidic Ocean'

Corals 'Could Survive a More Acidic Ocean'
Show

Corals may be better placed to cope with the gradual acidification of the world's oceans than previously thought -- giving rise to hopes that coral reefs might escape climatic devastation.

In new research published in the journal Nature Climate Change, an international scientific team has identified a powerful internal mechanism that could enable some corals and their symbiotic algae to counter the adverse impact of a more acidic ocean. ...

Pace of Ocean Acidification Has No Parallel in 300 Million Years, Paper Says
Show

A new scientific paper suggests that the ocean is acidifying at a rate that is many times faster than at any time in the last 300 million years. The change is occurring so rapidly that it raises “the possibility that we are entering an unknown territory of marine ecosystem change,” said the paper, published this week in the journal Science. ...
