Acid Test: Rising CO2 Levels Killing Ocean Life

The ocean absorbs approximately one-third of all human-caused carbon dioxide emissions at a rate of 300 tons per second, which helps slow global climate change.  But, due to that carbon dioxide absorption, the ocean is now 30 percent more acidic than before the Industrial Revolution, and the rate of change in ocean pH, called ocean acidification, is likely unparalleled in Earth’s history.

With today’s levels of atmospheric carbon dioxide so high, the ocean’s help comes at a cost to marine life and the millions of people who depend on healthy oceans.
