Sky News Australia The "Deadly Trio" of Carbon Dioxide Threatens the World's Oceans Motherboard (blog) “At carbon dioxide concentrations of 450-500 ppm (projected in 2030-2050) erosion will exceed calcification in the coral reef building process,...
Earth’s oceans are currently more acidic than they have been in at least 300 million years, according to a report released today by the International Program on the State of the Ocean (IPSO). If that's the case, it's a condition that may have shoved us mostly unawares into the next great extinction event.
The IPSO researchers explain that acidification is one of three primary symptoms currently threatening our planet’s waters. The other two members of what they coined the “deadly trio” are ocean warming and deoxygenation. While all three have their own unique and detrimental effects on the ocean, they are all connected by a single source of causation: carbon dioxide.
Beyond their common carbon history, this triad is otherwise significant because “most, if not all, of the Earth’s five past mass extinction events have involved at least one of these three symptoms of global carbon perturbations," reads the report. But how did it get this way?
