Ocean technology ‘could increase CO2 absorption’

Building a series of water treatment plants to help the ocean to absorb carbon dioxide from the atmosphere could reduce global warming, US researchers say.

About 100 such plants — which essentially use the ocean as "a giant carbon dioxide collector" — could cause a 15% reduction in emissions over many years, they say. About 700 plants could offset all CO2 emissions.

In the new study, Kurt Zenz House and colleagues propose building hundreds of special water treatment facilities worldwide.
