Seawater turned acidic by greenhouse gases surfacing off B.C.

VANCOUVER - Greenhouse gases have so profoundly altered the world's oceans that scientists say "corrosive" acidified water is now surfacing off the west coast of North America.

The water, capable of dissolving the shells of marine organisms, is rising up from the deep ocean along the coast from Vancouver Island to Mexico, an international team reported Thursday in the journal Science.

The corrosive water has shown up decades earlier than expected, say the researchers who warn of far-reaching impacts on the marine ecosystem.
