Scientific American: Much of the change in climate change is happening to the ocean. It`s not just the extra heat hiding within the waves. The seven seas also absorb a big share of the carbon dioxide released by burning the fossilized sunshine known as coal, natural gas and oil. All those billions and billions of CO2 molecules interact with the brine to make it ever so slightly more acidic over time and, as more and more CO2 gets absorbed, the oceans become more acidic. Now scientists have delivered the most comprehensive...
Science chief warns on acid oceans

BBC: The UK's chief scientist says the oceans face a serious and growing risk from man-made carbon emissions. The oceans absorb about a third of the CO2 that's being produced by industrial society, and this is changing the chemistry of seawater. Sir Mark Walport warns that the acidity of the oceans has increased by about 25% since the industrial revolution, mainly thanks to manmade emissions. CO2 reacts with the sea water to form carbonic acid. He told BBC News: "If we carry on emitting CO2...
