Ocean acidification: another path to EPA rules on carbon emissions?
In a legal settlement Thursday, the EPA agreed to help states test coastal waters for acidity, and to weigh whether to tighten rules on carbon emissions to address ocean acidification.
Move over global warming. Ocean acidification is getting its day in court.
Nearly three years after the US Supreme Court found that carbon dioxide was a pollutant that fell under the purview of the Clean Air Act, the US Environmental Protection Agency has agreed to explore approaches for tightening its regulations dealing with ocean acidification under the Clean Water Act.
Ocean acidification results from the ocean's uptake of carbon dioxide from the atmosphere. Many scientists have become increasingly concerned about the effect industrial emissions of CO2 are having on the chemistry of the world's oceans and about the fallout for many species of marine animals.
The oceans take up as much as half the CO2 emissions humans pump into the atmosphere each year.
