Global warming also threatens the oceans

Re "No denying it: Climate change is here -- and now" (Editorials, May 9): Greenhouse gas emissions are not only affecting the atmosphere. The National Climate Assessment also states that a fourth of emissions are being absorbed by oceans, leading to rising acidity.

What is not so easily seen is how the base of the marine food web is being threatened: coral, zooplankton and shellfish are listed examples. Eventually billions of people who rely on the ocean as a food source will feel the effects.

So where does the responsibility lie? The U.S. Energy Information Administration has compiled data on carbon dioxide released by each country from as early as 1980. This data extends to as recently as 2011, and reveals Asia and the U.S. as the two largest carbon contributors. Although Asia may produce more emissions, it does not mean we can turn away from our own responsibility to reduce our footprint.
