The document discusses the effects of increasing carbon dioxide levels in the atmosphere and oceans. It notes that the ocean absorbs one third of excess CO2 in the atmosphere, and that CO2 concentrations have risen from 280 to 387 parts per million currently and are projected to reach 450 to 550 ppm by volume. It also explains that the ocean is becoming more acidic as it absorbs more CO2, with the pH dropping by 0.1 currently and projected to decrease by 0.3 to 0.7 additional units by 2300, putting coral, clams, and plankton at risk.
