The Port of Seattle is leading many efforts to reduce greenhouse gas emissions (GHG emissions), the most important step towards combatting ocean acidification. In absorbing so much of the carbon emissions from the atmosphere, the pH level of the ocean surface has increased an estimated 30 percent since the start of the industrial revolution 200 years ago. Dead Zones. How NRDC helped form an unlikely alliance to help protect 38,000 square miles of unique habitat in the Atlantic. How Much Can the Worst Coral Bleaching Event on Record Be Blamed on Climate? New research has found that pollution from plastic waste dumped into the worlds oceans is correlated with ocean acidification, which occurs when the waters chemistry is altered as CO2 is absorbed by seawater. For more than 200 years, or since the industrial revolution, the concentration of carbon dioxide (CO2) in the atmosphere has increased due to the burning of fossil fuels and land use change. Floating plastic is easier to spot and collect using nets and amounts are still debated. More technically: CO2 and water produce carbonic acid, which releases hydrogen and bicarbonate ions. Ocean acidification is sometimes called "climate change's equally evil twin," and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. Marine Plastics | Smithsonian Ocean Its high time we got ourselves out of it. The U.S. EPAs Ocean and Coastal Acidification Program promotes awareness and conducts research and long-term monitoring to mitigate impacts of acidification and develop solutions.
