Ocean CO2 may ‘harm marine life’

Nearly 50% of the carbon dioxide that humans have pumped into the atmosphere over the last 200 years has been absorbed by the sea, scientists say.

Consequently, atmospheric levels of the potent greenhouse gas are not nearly as high as they might have been.

But the heavy concentration of carbon dioxide in the oceans has changed their chemistry, making it hard for some marine animals to form shells.
