all carbon currently stored in the ocean The ocean absorbs 9 Gt CO2 every year This represents approximately 23 of annual emissions Currently, the majority of our emissions remain in the atmosphere In the absence of active CDR, much of the atmospheric CO2 will eventually be absorbed by the ocean anyway, but with detrimental effects
Key Points: The ocean absorbs 25-30 percent of carbon dioxide emissions from the atmosphere, roughly 22 million tons per day, according to NOAA As the ocean absorbs carbon dioxide, it reacts with water molecules to form carbonic acid, thereby increasing the overall acidity
times as much as the average person living outside of the United States Together, Americans produced 6 5 billion of the 27 7 billion tons of carbon dioxide generated in 2003, and these numbers are growing every year 3 Ocean acidification is a straightforward consequence of increasing carbon dioxide emissions due to human activities,
The ocean has also absorbed about one third of the total anthropogenic CO 2emissions from human activities A result of the uptake of anthropogenic CO 2by the ocean has been its acidification
OCEAN ACIDIFICATION 101 Ocean acidification (OA) is caused by burning fossil fuels like coal, oil and natural gas, which releases carbon dioxide (CO2) into the atmosphere Excess CO2 from burning fossil fuels doesn’t just stay in the air: like a giant sponge, the ocean naturally absorbs much of it And, as a result, the ocean’s chemistry
