It’s been called global warming’s evil twin. Scientists have pegged it as the culprit behind low shellfish harvests, and some researchers warn that it will kill off some of the main players at the base of the marine food web.
(From High Country News / by Samantha Larson)– Commonly called ocean acidification, the phenomenon occurs when carbon dioxide infiltrates the sea, changing the water chemistry and thus lowering the pH. And while we usually think of it in the context of a global affliction — it is driven by the same rise of CO2 in the atmosphere that also drives climate change — a report released Monday points out that it is also a local problem, with uniquely local solutions.
In short: If we’re worried about Puget Sound’s acidifying waters, we should clean up the wastewater that we’re pouring into it.
The report, released by the nonprofit California Ocean Science Trust and written by a panel of 20 scientists in California, Oregon and Washington, still points to global CO2 emissions as the dominant cause of ocean acidification. The researchers’ top recommendation is for the world to get its collective act together and finally start reducing those emissions.
