January 3, 2020 — Ocean acidification threatens to cause billions of dollars in damage to the U.S. economy, harming everything from crabs in Alaska to coral reefs in Florida and the Caribbean, NOAA researchers said in a new report.
Carbon dioxide emissions and ocean acidification are occurring at an “unprecedented” rate, deteriorating valuable fisheries and tourist destinations across the United States and its territories, NOAA said in a draft research plan for ocean acidification.
“Commercial, subsistence and recreational fishing [and] tourism and coral ecosystems” will likely be damaged by ocean acidification, the plan said. Multibillion-dollar fisheries such as West Coast Dungeness crab, Alaska king crab and New England sea scallops are vulnerable. So are Florida’s coral reefs, an asset valued at $8.5 billion.
Implicating human activities such as burning fossil fuels, the plan said that ocean acidification “is driven by the growing amount of anthropogenic carbon dioxide absorbed and dissolved in the upper ocean.” Ocean acidification makes it hard for some marine organisms such as lobsters, oysters and coral to build shells and skeletons.
