In addition to the famous impacts of atmospheric carbon on global warming, there is an equally worrisome effect of carbon dioxide on the oceans: ocean acidification (or OA for short). Here at I2SEA we have a series of resources about OA, including Our Acidifying Ocean, which is an introductory activity and virtual lab (note: now mobile compatible!).
A student suggested that we start a conversation topic about OA, and here it is! Have you heard about Ocean Acidification? If so, are you worried about it? How do you think we can best raise awareness about it among your fellow students and the general public? Have you seen particularly good links or films about OA that you would like to share? What are you doing to address the problem?

Ocean acidification is no joke. So many different sea animals are going extinct, many of these are keystone species. For example coral reefs are a big concern because they are going through mass extinction, this is because of the carbon getting into the ocean and heating it up. This happens because the carbon is reducing the ph levels and making the ocean more acidic which corals react very poorly to because the water is so warm, the coral will expel the algae that lives in their tissues and the coral will turn white, if the algae doesn’t come back the coral will die. This can happen in 4 weeks if the water goes up by 1 degree celsius, if this keeps happening we will have no coral in the future and coral reefs are a keystone ecosystem for so many species.
I completely agree with this. Ocean acidification needs to be talked about more so that a difference can be made. The longer we wait, the harder it would be to come back from our mistakes. Keystone species are a crucial part to our ecosystems and many more species will die if we keep doing what we are doing. Our planet is warming at such an alarming rate, organisms don't have time to evolve and adapt to these new circumstances. The last time the earth's climate changed this much there was a mass extinction. We need to worry about our carbon emissions now, so that in the future coral still exists.
I agree with what you are saying nora. The oceans have never been this warm and I don’t think they will ever go back down. Even if the feature we reduce the amount of carbon we produce we can’t bring the coral back to life. We have to take action now if we want to save our oceans. I’m fortunate enough to have gone snorkelling before and see how beautiful the coral is. I and assume everyone else wants to be able to go snorkelling with their own kids, and not have to tell them about them like we talk about dinosaurs today.
I agree with everything that u guys are saying. There is absolutely no way we can fight a problem most people don’t even know is happening. Most people hear about oceans being polluted by micro plastics but not how the fundamental chemistry of our oceans are being changed. And un like most climate issues where there are a hole bunch of different causes we know that this is being caused by an increased amounts of carbon in the atmosphere. Which causes the ocean to heat up. People say it’s hard to fight for something you can’t feel or see happening. This is why the worming of the planet is being so strongly fought for but you can see the impacts of worming oceans. When you see the news that says we are in a mass extinction event and you go back to your favourite scuba diving or fishing spot and there are no fish and the coral Reeves are bleached. Or u dip you feet in the ocean and don’t feel that familiar numbing cold. Our every impact is shown all around us and if we are going to solve this problem you can’t look away.
I as well agree with what your saying about ocean acidification. It's really sad and disappointing to see how much ocean life is going extinct and is in danger because of it. Coral reefs are very important and its honestly scary that they can die so fast just from the water changing its temperatures. They help and benefit many sea creatures and if this continues it will change the future of of our ocean life. We really need to stop polluting and try to protect our oceans before it gets to late.
Ocean Acidification is when the ocean becomes more acidic due to too much carbon dioxide in the air. The ocean absorbs this and it then mixes with the water which forms an acid. This acid can be harmful towards sea life like clams, oysters, and coral because it makes it harder for them to build their shells. Many sea animals like fish, depend on coral reefs for a place to live and to have shelter. If we continue to pollute the air, ocean acidification can become even more harmful not only to us but to ocean life as well.
Ocean acidification is a worldwide environmental issue mainly resulting from the increase in carbon dioxide (CO₂) levels in the atmosphere due to human activities such as burning fossil fuels and deforestation. When the ocean takes up too much CO₂, it dissolves into seawater to form carbonic acid, which lowers pH and reduces the amount of carbonate ions—a crucial ingredient for sea animals that build shells and skeletons, including corals, mollusks, and some plankton. This chemical process makes it more difficult for these animals to survive, breed, and maintain healthy populations, and threatening entire ocean food webs. The sources of ocean acidification have a lot to do with industrialization and continued reliance on carbon-releasing energy sources. The sea is projected to absorb about 30% of atmospheric CO₂ emissions, buffering global warming but accelerating acidification. Impacts are extensive, penetrating biodiversity, fishery, and marine-based coastal communities relying on the sea for livelihood and food. Coral reefs, which support around 25% of marine life overall, are particularly vulnerable and face increased threats of bleaching and erosion. Ocean acidification also effects the ocean's ability to store carbon, potentially reducing its potential to buffer climate change in the long term. This can be addressed through international cooperation to reduce carbon emissions, advance sustainable development, and tailor efforts to affected communities and ecosystems.
Thanks for sharing this! Ocean acidification is something I didn’t know much about until recently, and your post really helped break it down. It's wild how something like CO₂—something we can't even see—can have such a big impact on sea life.I didn’t realize coral reefs support that much marine life. That really puts into perspective how serious this is, especially for people who rely on fishing or live near the coast. It's kind of scary, but I like how you mentioned that there are solutions, like working together internationally and focusing on sustainability.
I’ve been trying to be more mindful about energy use, like unplugging stuff I’m not using and choosing more eco-friendly products. It feels small, but I think every little bit helps. Thanks again—your post was super informative and made me think more about how connected everything really is. ?
I learned that rising ocean temperatures are making coral reefs bleach and die. Coral reefs are really important because they give shelter and food to tons of sea animals. I read that climate change and pollution are the main causes of this problem. I think we should all try to help the planet by using less plastic and saving energy.\
I had never heard of this phrase until recently, but it is one of the many effects of climate change. So, what is it? Basically, ocean acidification in the phrase used to describe the increasing acidity of the ocean. This is due to the ocean absorbing massive amounts of carbon dioxide from human activities. The more carbon dioxide that is put out into the atmosphere from activities like burning coal for power, the more the ocean absorbs. When that happens, it raises the acidity of the water. While it may not harm humans, it causes lots of harm to the ocean life. For example, the increasing acidity of the water has been harming coral reefs. Because they are unable to adapt quick enough to withstand the sudden changes, the coral die off. This leaves many aquatic species without protection from predators. While this is only one species that is suffering, soon enough all ocean life will be killed off by the raising acidity. This could spell disaster for many societies that rely on ocean life to feed themselves or to keep them employed. That is why it is so important to take climate change seriously, and to start working as a society to reverse the effects of climate change.
I recently learned about ocean acidification, and it really opened my eyes to another dangerous effect of climate change. Ocean acidification happens when the oceans absorb too much carbon dioxide from the atmosphere, mostly due to human activities like burning fossil fuels. This makes the water more acidic and harms marine life.
I think it’s important for all of us to be aware of this issue and support actions that reduce CO₂ emissions. Even small steps can make a difference when done together.
I had a similar experience, recently I learned more about ocean acidification. I had heard of it before but never fully knew what it is until last month during a science research trip to Belize where we read about ocean acidification and the effects of global warming on the ocean's ecosystems. I learned that when the ocean absorbs excess carbon dioxide it lowers the water's pH levels causing the water to become more acidic. This is happening because humans are producing Co2 faster than nature and the ocean can absorb it. Like the previous posts mentioned it is really sad how this is happening. The affects of ocean acidification are tragic for sea corals and animals as it results in a lot of habitat loss.
Combating ocean acidification is crucial for the health of marine ecosystems and the livelihoods that depend on them. As carbon dioxide levels rise, more of this greenhouse gas is absorbed by the oceans, leading to a decrease in pH levels and disrupting the delicate balance of marine life. Coral reefs, shellfish, and various marine organisms struggle to build their calcium carbonate structures in increasingly acidic waters, threatening biodiversity and fisheries. Effective strategies to address ocean acidification include reducing carbon emissions, promoting sustainable practices, and restoring coastal habitats like mangroves and seagrasses, which can help buffer changes in pH. Collaborative global efforts, research, and public awareness are vital to mitigate the impacts of ocean acidification, ensuring the resilience of our oceans for future generations.
Ocean acidification is expected to have negative overall effects on many marine species. This could alter marine food chains and food supply to humans. Ocean acidification occurs when carbon dioxide (CO2) is absorbed rapidly into the ocean. It reacts with water molecules (H2O) to form carbonic acid (H2CO3). This compound then breaks down into a hydrogen ion (H+) and bicarbonate (HCO3-). These hydrogen ions decrease seawater pH.
Ocean acidification is a rising environmental issue that poses a significant threat to marine ecosystems. As carbon dioxide levels rise in the atmosphere,a portion is absorbed by the oceans, leading to a decrease in pH levels. This chemical shift can have devastating effects on marine life, particularly organisms with calcium carbonate shells or skeletons, such as coral reefs and shellfish, which struggle to maintain their structures in more acidic waters. To help this issue, we can take action by reducing our carbon footprints through lifestyle changes. Such as advocating for renewable energy sources, and supporting policies aimed at decreasing greenhouse gas emissions. Promoting awareness and education about ocean health can help communities to engage in conservation efforts to help our oceans.
I have also found a link about more information in ways we can help our oceans and marine life. https://texanbynature.org/2019/08/5-way … our-ocean/
I had no idea that what we put out goes all the way into the oceans...that is really sad to read about. Putting this post up will definitely help with my drive to cut down on carbon emissions.
Ocean acidification is a significant environmental issue caused by excess atmospheric carbon dioxide being absorbed by the oceans. This process lowers the pH of seawater, making it more acidic. According to the National Oceanic and Atmospheric Administration (NOAA), ocean acidification has detrimental effects on marine life, mainly the organisms with calcium carbonate shells and skeletons. These species are vital to the marine food web and their decline can disrupt entire ecosystems, affecting biodiversity and fisheries that we rely on. The NOAA suggests several strategies, reducing CO2 emissions is paramount, which can be achieved by transitioning to renewable energy sources and enhancing energy efficiency. Protecting and restoring marine ecosystems, such as seagrass beds and mangroves, can also help as they absorb CO2. Additionally, improving monitoring and research on ocean chemistry and its impacts can guide effective policy and conservation efforts. We need to work harder on reducing our carbon footprint!
The increase in acidification in the ocean has impacted all sea creatures with shells and or bones that are made of calcium due to the flow of carbonated calcium going from net positive to net negative.
Hi! At my house, I recently downloaded a coding game, and I was planning on coding a video-game focusing on helping creatures that are being harmed from Ocean Acidification. The game would be centered on quests that the player would go on to help ocean creatures--- but that's beside the point. I can't think of any creatures right now!!! Do any of you have any ideas for ocean creatures and some quests to help them? Please spare me the coder's block! :,(
(P.S.) (I wanted to code this game to raise awareness of Ocean Acidification. Just an FYI!)
Protecting the ocean is essential for life on Earth.Oceans are vital sources of oxygen,food and resources,and their conservation is crucial to our health and the health of global ecosystems.
Yes, I agree but how do we protect our ocean from acidification? First, we must understand what causes acidification. Ocean acidification is caused because more carbon dioxide is dissolving into the Ocean than ever before. It is natural for CO2 to dissolve into the ocean because the Ocean is a carbon sink. However, because of the industrial revolution and deforestation a surplus amount is being absorbed by the ocean which lowers the ocean's pH levels. The lower the pH levels are the more harmful it is to certain organisms who depend on the Ocean to survive. We must find ways to lower our carbon emissions as a whole to prevent any further extra acidification.

I agree, and even little things you can do at home can help protect ocean life. Things such as properly disposing of waste and conserving water are great ways to help even just a small amount. Another great way is to use less energy around the house, ways to do this are using energy efficient appliances and lightbulbs, keeping lights off when your not using them, and trying to limit large appliance usage. Even if these make a small difference if everyone pitches in we can help the bigger picture greatly. Many corporations also help contribute to restoring and conserving ocean life, they do this through many techniques such as rebuilding reefs and salt marshes that guard against storms and flooding, and protecting "Super Reefs" which are reefs which can survive hot temperatures and are used to help grow new generations of coral. We can make a difference by supporting and donating to these corporations which often rely on donations to operate.
I completely agree; oceans are one of the most important contributors to human life. However, humans have caused great damage to the ocean. So how can we protect the ocean, and keep it healthy? Well, according to National Geographic, there are over 5.25 trillion of plastic in the ocean. This plastic kills sea life and is incredibly damaging to the ocean. To fix this, we can try to limit the plastic we use and correctly sort our trash. For example, instead of buying Ziploc bags, you can buy glass containers, which are reusable and don't cause damage to the environment after you dispose of them. Limiting your use of plastic leads to less plastic being put in the ocean. Similarly, we can also protect our ocean from acidification. Ocean acidification is the decrease in the pH of the ocean caused by too much carbon dioxide. The ocean naturally absorbs CO2, but abounding too much can lead to acidificaction, which harms sea plants and animals. To stop this crisis, we can try to limit our carbon footprint. According to I2SEA, the average human produces 3 791 kgs of CO2 per year, and even more in the United States. To reduce this number, we can drive to avoid driving and can use public transportation, biking, or walking instead. We can also try to invest in renewable energy sources, like solar panels, which use energy from the sun for electricity. This not only reduces your carbon footprint but saves you money. You can also try to eat less meat. Animals produce a lot of greenhouse gases, and not eating meat means not giving money to these companies that exploit and harvest animals.
What is ocean acidification? Well, for starters, it is the ongoing decrease in the pH of the Earth's ocean. This is caused by the uptake of carbon dioxide in the atmosphere. This topic is important to the carbon footprint because it’s caused by all the carbon dioxide. When taking the survey, it gave us numbers that show how much carbon dioxide we produce throughout the things that we do. These things include any type of transportation, what kind of food you eat, how often you use energy in your house depending on if it’s gas or electric, and the things you buy. Bad things could happen to our waters if we don’t make an attempt to prevent ocean acidification. For example, the first thing that affects us is that we won’t be able to swim in the ocean. The second example is that these changes can affect seafood supplies and the ocean's ability to store pollutants, including future carbon emissions. You may ask, “what are some ways that we could prevent this though?” Well, even living in the midwest away from oceans, reducing the amount of carbon dioxide emissions at home, at the office, and on the road can still help with the problem. The carbon dioxide that we as humans release comes from burning fossil fuels. When we do that, it increases the acidity in the ocean allowing carbon dioxide to dissolve. The best things to do in a home that helps decrease the amount fossil fuels being burned include, swapping your furnace for a heat pump (many people in Canada rely on fossil fuels to heat homes), replacing your gas water heater with a heat pump water heater, trading your gas stove for an induction stove, and replacing your gas fireplace with an electric one. You can also use LED lights in the house that helps with the amount of energy being used. More things that people can do include turning off lights, computers, televisions, video games and other electrical equipment when you're not using them, limiting the use of air conditioning, and trying to use more things that take electricity instead of gas, like cars or stoves. These are all easy ways that humans can prevent ocean acidification. The hard thing is trying to get multiple people to go to beaches and pick up all the litter and trash people are throwing and letting dissolve into the ocean and atmosphere. For many years, people have been trying to get others to quit littering, lawmakers have even tried to make it illegal, but that doesn’t stop everyone. Although, the less people emitting fossil fuels, the better. Overall, if more people make an effort to do these things, then the ocean will be thriving again and coral reefs will stop fading in color.
