Climate change drastic

CLIMATE change may lead to disturbances in marine life that will take thousands of years to recover from, not hundreds of years as previously thought, researchers said this week.

The study in Proceedings of the National Academy of Sciences is based on a section of fossilised ocean fauna found on the sea floor off the Californian coast dating to between 3 400 and 16 100 years ago.

Researchers sliced up the sediment like a cake for a before-and-after glimpse of how creatures were affected by climate change during the last major deglaciation, when polar ice caps melted abruptly and low oxygen zones expanded in the ocean.

Ice melt and ocean dead zones are an increasing concern today, as scientists study the warming planet.
