Global warming's other effects on the oceans

摘要

The often overheated debate over the effect of anthropogenic CO_2 on the earth's atmosphere has distracted scientists from considering how this greenhouse gas might be affecting other global systems,warn some researchers.Two related papers published in Science in July estimated that as much as one-half of the anthropogenic CO_2 is being sucked up by the oceans,increasing ocean carbon levels and lowering the average pH from a preindustrial level of 8.16 to 8.04 today.
