Acidic oceans affecting food fish

Carbon dioxide emissions could shake “the biological underpinnings of civilization” as increasingly acidic water undermines the oceanic food web, according to fresh research from the Pacific Ocean off Alaska.

The research shows that increasingly acidic Pacific water will affect king crabs and a snail that is a favorite food of Pacific salmon. How disruptions in the ocean food web could ultimately harm these and other popular food species is still uncertain.

The Senate Subcommittee on Oceans, Atmosphere, Fisheries, and Coast Guard will hear testimony today on the acidification of oceans from private, government and environmental group scientists.

Oceans had until recently been viewed as a great savior of the climate, because they have absorbed about one third of the carbon humans have emitted, buffering what would otherwise have been a greater warming of the atmosphere. But scientists have in recent years begun studying the consequences of oceanic carbon storage – a 25 percent increase in acidity since pre-industrial times.
