As Senator Whitehouse has described, our oceans show the effect of climate change by absorbing much of the heat from our warming planet. But they do more than that; our oceans absorb almost 25 percent of the carbon that humans release into the atmosphere. If they did not, even more greenhouse gasses would warm our planet at an even faster pace. Our oceans and the life in them pay a price for all of this carbon. Increasing carbon dioxide creates a chemical reaction that raises the acidity of the sea water. This is called ocean acidification. So that is a technical term, but what does it mean as a practical matter? In plain terms, ocean acidification makes it difficult for shellfish, corals, sea urchins, and other creatures to form the shells that they need in order to live. As a result, fewer survive, which means entire populations are put at risk. Acidification negatively affects crucial parts of the ocean food chain from shellfish and coral reefs to fisheries. So what does this mean for human beings? Ocean acidification has real economic consequences for communities that depend on the ocean for food, for jobs, and for tourism, such as my home State of Hawaii. Further acidification and warming will hurt our local fishing and tourism industries, industries that make up the backbone of our economy. All the fish and the seafood we depend upon may become scarcer and likely more expensive.…
