Carbon dioxide (CO2) is a gas produced by all living organisms and through the burning of fossil fuels. It plays a significant role in global warming. But what if we could capture and store it underwater?
Every time you breathe out, you release CO2. Each exhale contains more CO2 than what you inhaled, adding up to about 2 pounds of CO2 per person each day. Although CO2 is colorless and odorless, it can be harmful in high concentrations.
Earth operates as a relatively closed system, meaning carbon is continuously recycled. While individuals release small amounts of CO2, industries emit large quantities. If we don’t capture this CO2, the greenhouse effect will worsen. In 2014, it was estimated that 37 gigatons of CO2 were released into the atmosphere, exceeding the planet’s capacity to absorb it. This is a serious issue.
Scientists are exploring ways to filter and capture CO2. In the 1930s, researchers found that bubbling air through a solution of ammonia derivatives could remove CO2. In 2014, MIT developed a process using electrochemistry. They used amines to capture CO2, and when copper ions were introduced, the CO2 was released from the system.
After CO2 is captured, it needs to be stored. Industries have developed Carbon Capture and Storage (CCS) technologies. Typically, companies cool the CO2 until it becomes liquid and then transport it for storage. There are two main methods: geologic and oceanic carbon sequestration.
This method involves injecting CO2 into porous rock formations deep underground, where it is expected to stay securely. In the U.S., 36 suitable regions have been identified for this purpose.
This method involves pumping liquid CO2 to the ocean floor. Since liquid CO2 is denser than water, it could theoretically be contained beneath the ocean surface. A study suggested that this could create a lake of liquid CO2 at the ocean’s depths, where it could remain stable for up to 1,000 years.
Both methods carry risks. In geologic sequestration, if CO2 escapes from the rock, it could cause environmental harm. In oceanic sequestration, the release of CO2 could increase ocean acidity, threatening marine life and causing ecological damage.
Ultimately, the best solution to the CO2 problem is reducing carbon emissions. Pollution affects not only the planet but also human health. It’s important to think about our carbon footprint and find ways to reduce fossil fuel use.

Carbon dioxide (CO2) is produced by all living organisms on Earth and through the burning of fossil fuels, contributing to global warming. So, what if we could capture it all and store it underwater?
Hello, everyone! Trace here for DNews. Every time you breathe out, you’re releasing CO2. In fact, each exhale contains significantly more CO2 than what you inhaled, amounting to about 2 pounds of CO2 per person each day. Carbon dioxide is colorless, odorless, and can be harmful in high concentrations.
Earth operates as a relatively closed system, meaning carbon is recycled continuously. While individuals release a small amount of CO2, industries emit large quantities, and if we don’t find ways to capture it, the greenhouse effect will worsen. In 2014, it was estimated that we would release 37 gigatons of CO2 into the atmosphere, exceeding the planet’s capacity to absorb it. This is a pressing issue.
Scientists are exploring methods to filter and capture CO2. In the 1930s, researchers discovered that bubbling air through a solution of ammonia derivatives could effectively remove CO2 from the air. More recently, in 2014, MIT developed an efficient process using electrochemistry. They utilized amines to capture CO2, similar to the earlier method, but introduced a modern twist. When polluted air is bubbled through an amine solution, the amines naturally attract CO2. However, when copper ions are introduced, the amines prefer to bond with the copper instead, allowing the CO2 to be released from the system.
Once CO2 is filtered, what happens next? Due to strict regulations on CO2 emissions, industries have developed Carbon Capture and Storage (CCS) technologies. Typically, companies cool the filtered CO2 until it becomes liquid and then transport it for storage. There are two primary methods for this: geologic carbon sequestration and oceanic carbon sequestration.
Geologic sequestration involves injecting CO2 into porous rock formations deep underground, where it is expected to remain securely. In the U.S., the Geological Survey has identified 36 suitable regions for this purpose.
The second method, oceanic sequestration, involves pumping liquid CO2 to the ocean floor. Since liquid CO2 is denser than water, it could theoretically be contained beneath the ocean surface. A study in 2013 suggested that this could create a lake of liquid CO2 at the ocean’s depths, where it could potentially remain stable for up to 1,000 years.
However, both methods carry risks. In geologic sequestration, if the CO2 escapes from the rock, it could lead to serious environmental consequences. Similarly, in oceanic sequestration, the release of CO2 could increase ocean acidity, threatening marine life and potentially causing widespread ecological damage.
Ultimately, there is no permanent solution to the CO2 issue except for reducing carbon emissions. Pollution not only impacts the planet but can also affect human health.

This version maintains the core information while removing informal language and personal anecdotes.
Carbon Dioxide – A colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in the air and is absorbed by plants in photosynthesis. – Plants use carbon dioxide during photosynthesis to produce oxygen and glucose.
Global Warming – The gradual increase in the overall temperature of the Earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants. – Scientists are studying the effects of global warming on polar ice caps and sea levels.
Carbon Cycle – The series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels. – Understanding the carbon cycle is crucial for predicting climate change impacts.
Greenhouse Effect – The trapping of the sun’s warmth in the Earth’s lower atmosphere due to the presence of greenhouse gases like carbon dioxide, methane, and water vapor. – The greenhouse effect is essential for life on Earth, but an enhanced greenhouse effect can lead to global warming.
Capturing – The process of trapping carbon dioxide from the atmosphere or emissions sources to prevent it from entering the atmosphere. – Carbon capturing technologies are being developed to reduce the amount of carbon dioxide released into the atmosphere from power plants.
Storing – The process of keeping captured carbon dioxide in a stable form, often underground, to prevent it from contributing to atmospheric greenhouse gases. – Storing carbon dioxide underground is one method being explored to mitigate climate change.
Sequestration – The long-term storage of carbon dioxide or other forms of carbon to mitigate or defer global warming. – Forests play a vital role in carbon sequestration by absorbing carbon dioxide from the atmosphere.
Emissions – The act of releasing something, especially gas or radiation, into the atmosphere. – Reducing vehicle emissions is a key strategy in combating air pollution and climate change.
Pollution – The presence in or introduction into the environment of a substance which has harmful or poisonous effects. – Industrial activities can lead to air and water pollution, affecting ecosystems and human health.
Footprint – The impact or effect that a person, company, or activity has on the environment, often measured in terms of carbon emissions. – Reducing your carbon footprint can help decrease the effects of global warming.
