Scientists call rise in ocean acidification “unprecedented”

The ocean absorbs a third of C02 emissions worldwide, including what comes from fossil fuel use and deforestation. That leads to a decrease* in the PH of the water and a chemical change known as ocean acidification. Scientists say it could have significant consequences for both marine life and the millions of people whose lives depend on the ocean. A report by the National Research Council has found that acidification is happening at an unprecedented rate and today a Senate subcommittee discussed possible action. FSRN's Karen Miller has more.
