Carbon Emissions Creating Acidic Oceans Not Seen Since Dinosaurs

By David Abram for The Guardian/UK

Chemical change placing 'unprecedented' pressure on marine life and could cause widespread extinctions, warn scientists

Human pollution is turning the seas into acid so quickly that the
coming decades will recreate conditions not seen on Earth since the
time of the dinosaurs, scientists will warn today.

The rapid acidification is caused by the massive amounts of carbon dioxide
belched from chimneys and exhausts that dissolve in the ocean. The chemical change is placing "unprecedented" pressure on marine life such as shellfish and lobsters and could cause widespread extinctions, the experts say.
