Why ocean acidification could make some geoengineering schemes irrelevant

The idea of runaway ocean acidification has now joined the idea of runaway global warming as a threat so large that it stands almost co-equal in its danger. Part of the problem with ocean acidification is that geoengineering schemes for lowering Earth’s temperature by reducing the sunlight that reaches the Earth’s surface won’t affect ocean acidification.

Climate change’s ‘evil twin’: Ocean acidification

A three-year assessment from a team of international scientists will detail how the phenomenon dubbed “climate change’s evil twin” is shaping up to be a global problem. The rapid acidification of the Arctic Ocean will have widespread impacts to be felt for “tens of thousands of years” even if we stop emissions now, say the scientists.

Saving the oysters

“We’ve had so many people come up to us and say, ‘I heard you’re closing,’” says Terry Sawyer, co-owner of Hog Island Oyster Co. “There’s just a lot of misunderstanding about what’s going on.” Despite the rumors, Hog Island is alive and kicking, celebrating its 30th anniversary this year. With more than 100 employees, a thriving Tomales Bay oyster farm, two restaurants and a café, and additional projects in the works, Terry and his partner John Finger have turned what was once a modest dream into a Bay Area institution. But despite the farm’s success, Terry is worried about the oyster’s future, as are many farmers, marine biologists, ecologists, and bivalve lovers.
