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.
