A US National Research Council study, requested by US Congress released 22 April 2010 said ocean chemistry is changing at an unprecedented ratemagnitude due to human-made carbon dioxide emissions to the atmosphere. Excess carbon dioxide in the atmosphere?in addition to contributing to climate change?is absorbed by the ocean, making sea water more acidicleading to a suite of changes in ocean chemistry. The study said preliminary evidence suggests ocean acidification will have negative effects on corals, shellfish,other marine life, with wide-ranging consequences for ecosystems, fisheries,tourism.  EPA/NIC BOTHMA
