Humans are dumping so much carbon dioxide into the oceans so fast that seawater -- even in the Gulf of Maine -- is getting warmer and more acidic, according to marine and climate researchers. Scientists aren't sure yet how the trend, which is believed to be tied to human-induced climate change, will affect ocean life in the gulf. But there is rising concern -- especially among fishermen -- that changes in the ocean ecosystem could severely damage some of the fisheries that are the backbone of the region's seafood industry.
