CO2 and Ocean Acidification

This graphic is from GRID-Arendal, a Norwegian Foundation collaborating with the UN Environment Programme. It shows CO2 concentrations in the ocean going up over a period of 20 eyars, and the corresponding drop in pH over the same time period.

Ocean acidification is a serious effect of climate change.

As CO2 in the ocean goes up, pH goes down

As carbon concentrations in the atmosphere increase, so do concentrations in the ocean, with resultant acidification as a natural chemical process.

    Correction: “Ocean acidification AND CLIMATE CHANGE ARE a serious effect of EXCESS CO2”

    That may indeed be a better way to put it, thanks for the suggestion.
