Ocean Carbon Absorption Capacity: The Ocean's Superpower in the Fight Against Climate Change

Updated: Sep 22, 2023


Did you know that the ocean is a superhero in the fight against climate change? Recent research conducted by a team of scientists from the University of California, Los Angeles (UCLA) has revealed that the ocean's natural carbon absorption capacity is much higher than we previously thought. The study, published in the journal Nature Geoscience, found that the ocean absorbs twice as much carbon dioxide from the atmosphere as previously estimated.


This is great news for our planet! Carbon dioxide is a major contributor to global warming, and its increase in the atmosphere is one of the main drivers of climate change. The ocean has been absorbing significant amounts of carbon dioxide, which has led to ocean acidification and other detrimental effects on marine life. However, the UCLA study suggests that the ocean's capacity to absorb carbon dioxide is greater than previously thought, providing hope for mitigating the effects of climate change.


So how does the ocean absorb carbon dioxide? Well, it's all down to a process called the ocean carbon cycle. When carbon dioxide dissolves in seawater, it reacts with water molecules to form carbonic acid. This process is called ocean acidification, and it's the reason why the ocean's pH is decreasing. However, the good news is that when carbonic acid reacts with other compounds in seawater, it forms bicarbonate and carbonate ions. These ions can then combine with calcium to form calcium carbonate, which is used by marine organisms like coral to build their shells and skeletons. This process removes carbon dioxide from the water and stores it in the form of calcium carbonate.


The ocean's role in mitigating climate change is crucial. As the ocean absorbs more carbon dioxide, it helps to reduce the amount of carbon dioxide in the atmosphere. This, in turn, slows down the rate of global warming and the negative effects that come with it. The new findings from the UCLA study are a positive sign that the ocean can help us fight climate change.


It's important to note that while the ocean is doing its part to mitigate climate change, we can't rely on it entirely. We need to do our part in reducing our carbon footprint and protecting our oceans from threats like overfishing, plastic pollution, and habitat destruction.


Overfishing, for example, can harm the ocean's ability to absorb carbon dioxide. When fish populations decline, there are fewer fish to excrete calcium carbonate. This means that there are fewer compounds in the water to bind with carbon dioxide, which reduces the ocean's carbon absorption capacity. Similarly, plastic pollution and habitat destruction can harm marine organisms and disrupt the ocean carbon cycle. This can lead to a decrease in the ocean's ability to absorb carbon dioxide.


In conclusion, the ocean's natural carbon absorption capacity is a powerful tool in the fight against climate change. It's a superhero power that we need to protect and support. By reducing our carbon footprint and taking steps to protect our oceans, we can work together to ensure that the ocean's superpower continues to help us fight climate change.
