1 SEAWATER pH AND ANTHROPOGENIC CARBON DIOXIDE
Abstract. In 2005, the Royal Society published a report titled Ocean acidification due to increasing atmospheric carbon dioxide. The report’s principal conclusion—that average ocean pH could decrease by 0.5 units by 2100—is demonstrated here to be consistent with a linear extrapolation of very limit...

| Summary: | Abstract. In 2005, the Royal Society published a report titled Ocean acidification due to increasing atmospheric carbon dioxide. The report’s principal conclusion—that average ocean pH could decrease by 0.5 units by 2100—is demonstrated here to be consistent with a linear extrapolation of very limited data. It is also shown that current understanding of ocean mixing, and of the relationship between pH and atmospheric carbon dioxide concentration, cannot justify such an extrapolation. PACS: 91.62.La; 92.20.Cm; 92.20.Xy. Key Words: Ocean acidity; ocean mixing; carbon dioxide. |
