Ocean Acidification and Climate Change: How the Two Are Connected

Fish, Underwater, Corals, Sea, Ocean, Coral Reef

Climate change and the ocean are interconnected, and both pose serious dangers to our environment and human populations. 

Climate change is causing the Earth’s temperature to rise, which in turn is causing the oceans to acidify. This can have disastrous consequences for marine life and coral reefs. 

We must take steps to address climate change – and soon – so that we can protect our oceans and preserve our planet for future generations.

An introduction to ocean acidification

This introduction is intended for those who are new to the topic of ocean acidification, which is driven by climate change. 

The world’s oceans get increasingly acidic as they collect more carbon dioxide from the atmosphere. This is known as ocean acidification. It endangers marine life’s survival and has far-reaching effects on humans who rely on the water for a living.

There are numerous actions we can take to lessen our contribution to climate change and prevent ocean acidification. But first, we must comprehend the consequences of this happening.

What is ocean acidification?

Ocean acidification is a process that occurs when the ocean absorbs CO₂ from the atmosphere

This causes the pH of the ocean to drop, making it more acidic. As the ocean becomes more acidic, it becomes harder for marine life and coral to survive. Ocean acidification is one of the most serious threats posed by climate change.

Climate change and ocean acidification are interconnected threats to our planet, and if we want to protect our oceans, we need to first take action to address climate change.

The impact of climate change on ocean acidification

Coral bleaching

Coral bleaching is one of the most visible and devastating impacts of climate change on the ocean. 

Warmer water temperatures cause coral to expel the algae that live inside their tissues, turning them white. This process not only weakens corals, making them more susceptible to disease but also reduces their ability to produce food and shelter for other marine life.

Coral bleaching is often fatal for corals, and as a result, reefs around the world are in decline. It is estimated that nearly one-third of the world’s coral reefs have already been lost to bleaching. And unless we take action to reduce greenhouse gas emissions, this trend is only going to get worse.

In addition to coral bleaching, climate change is also causing ocean acidification

Ocean acidification

When carbon dioxide dissolves in seawater, it forms a weak acid called carbonic acid. This increase in acidity makes it harder for marine creatures like oysters and crabs to build their shells and skeletons. Acidification also harms plankton, which are the tiny plants and animals that form the base of the marine food chain.

Ocean acidification may not receive as much attention as coral bleaching, but it is no less dangerous. Together, these impacts of climate change are a serious threat to the health of our oceans and the creatures that live in them. We need to take action now to reduce greenhouse gas emissions and protect our planet’s vital oceans.

Coral bleaching and ocean acidification are just two examples of how climate change is impacting our planet. As we continue to pump greenhouse gases into the atmosphere, we can expect to see more extreme weather events, rising sea levels, and declining wildlife populations. We must take action now to mitigate these impacts and ensure a livable world for future generations.

Threats to marine life

As the ocean becomes more acidic, it threatens marine life that is sensitive to changes in pH levels. 

This includes coral reefs, shellfish, and plankton. The acidification of the ocean can cause these creatures to lose their ability to form shells or skeletons, making them vulnerable to predators and disease. As a result, we could see a decline in the populations of these animals, which are important for maintaining the health of our oceans’ ecosystems.

Serious consequences for marine economies

In addition to its impact on marine life, ocean acidification also poses a threat to human economies that rely on coastal resources. For example, shellfish aquaculture is worth billions of dollars each year, and industries such as tourism and fishing also depend on healthy coastal ecosystems. If ocean acidification continues to worsen, it could have serious consequences for these industries.

Lower resilience of coastal habitats

The decreased resilience of coastal habitats is yet another effect of ocean acidification stemming from climate change. 

As the temperature and pH of the oceans continue to decline, these delicate ecosystems are becoming less able to cope with disturbances. This can lead to a domino effect in which one disturbance can trigger a chain reaction that causes significant damage.

For example, research has shown that ocean acidification can make it more difficult for coral reefs to recover from bleaching events. In addition, shellfish populations have been declining as a result of increasing acidity levels, making it harder for them to build their shells. These impacts could have serious consequences for the people and wildlife that rely on coastal habitats for food and shelter.

We must take action now to protect these ecosystems before they are irreparably damaged. We need to reduce our emissions and invest in renewable energy sources so that we can stabilize the climate and prevent further ocean acidification. Only then will we be able to safeguard the future of our coastal habitats and the communities that depend on them.

The effect on the tourism industry

The ocean’s acidity has increased by 30% since the Industrial Revolution, and it is estimated to increase by a further 10% by 2100. 

This increase is caused by human emissions of carbon dioxide, which dissolves in seawater to form carbonic acid.

This rise in acidity will have major impacts on marine life, as well as the people who rely on the sea for their livelihoods. One of the most affected industries will be tourism. Coastal communities all over the world rely on visitors coming to enjoy their beaches and watersports.

However, as ocean acidification decreases the abundance of marine life, these areas will become less attractive to tourists. This loss of income will hit these communities hard, exacerbating existing socio-economic problems.

The acidification of our oceans is a serious and pressing issue, which we must address if we want to protect the livelihoods of coastal communities around the world. We need to find ways to reduce our emissions of carbon dioxide and invest in research that will help us understand and mitigate the effects of ocean acidification. 

Mitigating the effects of climate change and ocean acidification

There are a few key things we can do to help mitigate the effects of climate change and ocean acidification. Here are four simple steps you can take today:

Step 1: Educate yourself on the issue of climate change and ocean acidification.

The first step is education. 

Learn about the issue so you can be an advocate for change. There are many resources available online and in libraries. Get informed about what is happening and why it is happening. Once you understand the problem, you can start to look for solutions.

Step 2: Reduce your carbon footprint.

The less you contribute to climate change, the better off our oceans will be. There are simple, everyday actions you can take to decrease your footprint, and some financial institutions are even able to track your carbon footprint through your spending to help you offset your emissions. 

Step 3: Support politicians who prioritize climate action.

Vote for leaders who have a plan to address this global crisis.

Call your representatives and demand action on climate change. Let them know that this is important to you, and ask what they are doing to combat the problem.

Step 4: Get involved in local clean energy initiatives.

Show your community that you care about preserving our planet’s future.

There are many ways to get involved in your community and support clean energy initiatives. You can start by showing your neighbors that you care about preserving our planet’s future.
