Experiment with high CO₂ Levels

The ocean near the Vesuvius volcano has naturally had high CO₂ level for millennia, levels that we expect will occur all over the oceans from greenhouse gas emissions by the end of the century. Sea grass grows happily, but fish cannot spawn successfully. So we know exactly what to expect from our refusal to curb greenhouse gas emissions. We are increasing the CO₂ level ten times faster that at any time in earth’s history. The last time this happened, the CO₂ acidification wiped the corals out, along with all the fish that depend on them. It took them 10 million years to recover.
