Why ocean acidification could make some geoengineering schemes irrelevant
(WorldNews Environment)

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. And recent research from the Massachusetts Institute of Technology suggests that there is a tipping point in acidification beyond which the process becomes self-reinforcing and could...
