Anthropogenic CO₂ study quantifies amount and pathways in coastal ocean waters

Excess carbon dioxide emitted by human activities—such as fossil fuel burning, land-use changes, and deforestation—is known as anthropogenic carbon dioxide. Approximately 30% of this anthropogenic carbon dioxide in the atmosphere is absorbed by the world's oceans. While this absorption helps mitigate global warming, it also has adverse effects on marine life, including fish and plants.
