Ocean Acidification Rate May Be Unprecedented, Study Says

Summary- The world’s ocean may be turning acidic faster today from human carbon emissions than they did during four major extinctions in the last 300 million years. When natural pluses of carbon sent global temperatures high. The study is the first of its kind to survey the geologic record for evidence of ocean acidification over this vast time period. The ocean draws down the excess carbon dioxide from the air, the gas reacts with the seawater to form carbon acid. Which over time is neutralized by fossil carbonate shells on the seafloor. But if the CO2 goes into the oceans to quickly it can deplete the carbonate ions that corals, mollusks, and some plankton needed for reef and shell building.

Critique- Are they sure the world’s ocean is turning acidic faster today from human carbon emissions than they did during four major extinctions in the last 300 million years?

Impact- The CO2 can’t go into the ocean to quickly or else it can deplete the carbonate ions that corals, mollusks, and some plankton needed for reef shell building.
