Ocean acidification

Main article: Ocean acidification

Increased atmospheric CO₂ increases the amount of CO₂ dissolved in the oceans.^[47] Carbon dioxide gas dissolved in the ocean reacts with water to form carbonic acid resulting in ocean acidification. Ocean surface pH is estimated to have decreased from approximately 8.25 to 8.14 since the beginning of the industrial era,^[48] and it is estimated that it will drop by a further 0.3 to 0.4 units by 2100 as the ocean absorbs more anthropogenic CO₂.^[49] Since organisms and ecosystems are adapted to a narrow range of pH, this is a serious concern directly driven by increased atmospheric CO₂.

Global dimming

Main article: Global dimming

Scientists have stated with 66–90% confidence that the effects of volcanic and human-caused aerosols have offset some of global warming, and that greenhouse gases would have resulted in more warming than observed if not for this effect.^[1]

Ozone

Main article: Ozone depletion

Although global warming and ozone depletion often are linked in the media, the relationship between the two is not strong.
