Oceans Absorb CO2 Leading to Acidification

Before the industrial age, the ocean vented carbon dioxide to the atmosphere in balance with the carbon the ocean received during rock weathering. However, since carbon concentrations in the atmosphere have increased, the ocean now takes more carbon from the atmosphere than it releases.

Over millennia, the ocean will absorb up to 85 percent of the extra carbon people have put into the atmosphere by burning fossil fuels, but the process is slow because it is tied to the movement of water from the ocean’s surface to its depths. (1)

This uptake of CO2 by the oceans from the atmosphere is the primary reason foracidification, that is the reduction in the pH of the ocean over an extended period of time. (2)
