On the recordSeptember 20, 2012
My topic had been the acidification of our oceans as a result of carbon pollution now up 30 percent in acidity and projected to increase 160 percent in acidity at unprecedented rates in millions of years. It has been 50 to 300 million years since we have seen this kind of dramatic change in ocean acidity. For species that use calcium carbonate to create their shells and skeletons, such as oysters, crabs, lobsters, and the little plankton that so many other species depend on as the base of the food chain, it becomes harder for these species to thrive. These unprecedented changes I am talking about in ocean acidity are not happening alone, they are happening on top of dramatically changing ocean temperature that is also driven by carbon pollution. Just this week on the surface of the Earth, we experienced one of the hottest summers on record. The National Oceanic and Atmospheric Administration released this statement about the northeast shelf large marine ecosystem, which extends from the Gulf of Maine down to Cape Hatteras. Here is what they said: During the first 6 months of 2012, sea surface temperatures . . . were the highest ever recorded. Above average temperatures were found in all parts of the ecosystem, from the ocean bottom to the sea surface and across the region . . . The annual 2012 spring plankton bloom was intense, started earlier and lasted longer than average.…
