In a new study marine scientists have warn that the rate of ocean acidification presently occurring is unprecedented in the last 300 million years. This is due to dissolving carbon dioxide from the atmosphere, much of which human activity has contributed over the last 200 years through the use of fossil fuels. The extent and rate of acidification enhances the prospect for a mass marine extinction event this century. Research in paleoclimatology and oceanography has revealed that anthropogenic climate change is driving Ocean Acidification threatening marine ecosystems.
Ocean acidification has been called the 'evil twin' of climate change with marine scientists warning climate negotiators in Durban of the necessity for climate mitigation action in December 2011, along with a statement on the IUCN website urging action to cut carbon emissions. New research in November 2011 from Australia's Antarctic Climate and Ecosystems Cooperative Research Centre showed the Southern ocean is warming and freshening.
Marine scientists warn ocean acidification is already impacting marine food webs which will lead to substantial changes in commercial fish stocks, threatening protein supply and food security for millions of people. The Northwest Oyster Die-off from 2006-2008 in the USA highlights the growing impact on commercial fisheries. The United Nations Environment Program estimates that 3 billion people use fish protein in their diet, with one billion people dependent on subsistence fishing as a primary food source.
