SNIP: UNSW Australia researchers have found that carbon dioxide concentrations in seawater could reach levels high enough to make fish “intoxicated” and disoriented many decades earlier than previously thought, with serious implications for the world’s fisheries. The UNSW study, published in the journal Nature, is the first global analysis of the impact of rising carbon dioxide emissions from fossil fuels on natural variations in carbon dioxide concentrations in the world’s oceans.

“High concentrations of carbon dioxide cause fish to become intoxicated — a phenomenon known as hypercapnia. Essentially, the fish become lost at sea. The carbon dioxide affects their brains and they lose their sense of direction and ability to find their way home. They don’t even know where their predators are.” — Dr. Ben McNeil
