Ocean acidification blog

Jean-Pierre Gattuso, a senior research scientist at theLaboratoire d’Océanographie over in France has started a coral & ocean-acidification related blog entitled “Ocean acidification: An information outlet on ocean acidification“. His site is well worth reading (see Corals May Have Defense Against Global Warming, Acidic oceans may threaten fisheries) as an upto date resource on global … Continue reading Ocean acidification blog

CO2 emissions could violate EPA ocean-quality standards within decades

In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976] by mid-century if emissions are not dramatically curtailed now. This is the first recognition that atmospheric CO2 emissions will cause ocean waters to violate EPA water quality criteria.

 

The paper also says that carbon-dioxide induced “changes in ocean chemistry within the ranges predicted for the next decades and centuries present significant risks to marine biota” and that “adverse impacts on food webs and key biogeochemical process” would result.
