The ocean surface's average pH is currently estimated to be around 8.1, and to have dropped from about 8.2 since around 1800, before the industrial revolution took off, says Zeebe. A reduction of 0.1 units does not sound like much, but pH units are on a logarithmic scale, so a drop of one unit corresponds to a tenfold increase in acidity.

齐伯说：据估计，目前海洋表面的平均 pH 值大约下降到了8.1，在工业革命开始之前的1800年前后， pH 值为8.2.0.1的下降幅度听起来并不大，但是 pH 值单位利用的是对数标度，所以降低一个单位对应着酸度上升10倍。
