Climate change is a growing global threat to coral reefs, as their zooxanthellae are sensitive to ocean temperature and can cause coral bleaching episodes. To combat this, we must drastically reduce greenhouse gas emissions. Energy-efficient light bulbs can help reduce greenhouse gas emissions, and coral reefs are alive even when stirred-up sediment can smother them. To save coral reefs, we must act urgently against global and local threats, reduce pollution, protect areas in good condition, and restore degraded areas.
Climate-resilient corals may offer a lifeline to the future, and active interventions to assist adaptation include ways to enhance coral performance, such as thermal tolerance and lowering coral exposure. There are various creative solutions to reducing greenhouse gas emissions, including urban planning, carpooling, and forest protection.
The International Coral Reef Society (ICRS) has proposed three pillars for restoring coral reefs and mitigating further loss: reducing CO2 emissions, mitigating local stressors, and using cleaner transportation methods. While the world works towards reducing greenhouse gas emissions, we must also help coral reefs adapt to warmer temperatures caused by climate change. Anthropogenic greenhouse gas emissions have caused an increase in global surface temperature of approximately 1°C since pre-industrial times, leading to the prediction that we could lose over 90 of our coral reefs by 2050 if we don’t act urgently.
Climate emissions also increase ocean acidity, which can impact corals and the species that depend on them. By curbing carbon emissions and slowing down the rate of climate change, we can help coral reefs adapt to the rising temperatures and protect their survival.

How helpful greenhouse gases are in making the environment sustainable?
Greenhouse gases play a crucial role in maintaining Earth’s temperature for life. Without the natural greenhouse effect, Earth’s heat would escape into space, resulting in an average temperature of around -20°C. The greenhouse effect occurs when most infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted by greenhouse gas molecules and clouds. This warms the Earth’s surface and lower atmosphere.
Greenhouse gases absorb infrared radiation in the form of heat, which is circulated in the atmosphere and eventually lost to space. They also increase the rate at which the atmosphere can absorb short-wave radiation from the Sun, but this has a weaker effect on global temperatures.
Why are coral reefs dying and how can we save them?
Coral reefs are a significant concern due to their vital role in the marine ecosystem. Scientists have discovered that corals are highly sensitive to temperature changes, leading to the expulsion of algae that provide them with food. This results in coral bleaching and increased susceptibility to disease. Climate change and El Niño events exacerbate these bleaching events. To protect coral reefs, measures to address climate change and reduce pollution are needed.
Coral reefs are a keystone species for the marine world, and the loss of living coral impacts the entire ecosystem. Corals are a keystone species, and when they are lost, many other plants and animals also die. Losing coral reefs is not only detrimental to the health of our oceans but also for us.
Scientists have studied the cause of coral reef loss, finding that they are highly sensitive to temperature changes. When water temperature warms, corals expel the algae that provide them with food, leading to coral bleaching and increased susceptibility to disease. Addressing climate change and reducing pollution are crucial measures to protect coral reefs and the entire marine ecosystem.
How does CO2 affect corals?
Ocean acidification represents a significant environmental concern, with 48% of global fossil fuel emissions absorbed by the ocean. The acidification of the oceans has a detrimental impact on the growth of reef-building corals, rendering them more susceptible to disease and the destructive forces of storms. Research findings suggest that elevated CO₂ concentrations can impede coral productivity and elevate the risk of bleaching events by up to 50%.
How does pollution affect coral reefs?
Coral species face significant stress due to various factors, including sedimentation from coastal development, urban stormwater runoff, forestry, and agriculture. Sedimentation can smother corals, interfere with their ability to feed, grow, and reproduce, and support the growth of pathogenic microorganisms. Nutrients from agricultural and residential fertilizer use, sewage discharges, and animal waste can also contribute to the imbalance of coral reefs. Pathogens from inadequately treated sewage, stormwater, and livestock pens can cause disease in corals, especially if they are stressed by other environmental conditions.
Toxic substances, such as metals, organic chemicals, and pesticides, found in industrial discharges, sunscreens, urban and agricultural runoff, mining activities, and landfill runoff, can affect coral reproduction, growth, and other physiological processes. Herbicides can damage symbiotic algae, causing bleaching and damaging their partnership with coral. Metals and organic chemicals can also affect coral reproduction, growth rate, feeding, and defensive responses.
Trash and micro-plastics from improper disposal and stormwater runoff can snag on corals, block sunlight for photosynthesis, or entangle and kill reef organisms. Degraded plastics and microplastics can be consumed by coral, fish, sea turtles, and other reef animals, blocking their digestive tracts and potentially introducing toxics.
Can coral survive global warming?
Coral reefs, which support over 500 million people worldwide, are facing a significant threat due to global warming and climate change. The highest biodiversity of any ecosystem, coral reefs are at risk of becoming bleached due to increased global surface temperature caused by anthropogenic greenhouse gas emissions. UNESCO warns that coral reefs in all 29 reef-containing World Heritage sites could cease to exist by the end of this century if greenhouse gas emissions continue.
To ensure the survival of coral reefs globally, it is crucial to limit global average temperature to well below 2°C above pre-industrial levels in line with the Paris Agreement. This will provide the only chance for coral reefs to survive.
How does greenhouse help sustainability?
Greenhouse farming reduces water consumption by reducing water evaporation, allowing crops to be placed closer together, improving water efficiency through drip irrigation, and reducing water waste. The shorter crop cycle in greenhouses also helps conserve water over the growing season. As climate change becomes more noticeable, farmers can use technologies like drip irrigation, water reuse, soil moisture sensors, sub-irrigation, rainwater capture, micro irrigation, and climate-based irrigation to combat the adverse effects of climate change. These technologies ensure plants are not overwatered, providing the exact amount of water needed for optimal water use.
Are there any benefits to greenhouse gases?
Greenhouse gases, including CO2, water vapor, methane, nitrous oxide, and ozone, are essential for Earth’s livability by trapping heat energy in the greenhouse effect. Over the past century, human activities, such as burning fossil fuels like coal, oil, and gasoline, have produced CO2 as a waste product, contributing to Earth’s warming. The carbon cycle, which traces carbon’s path from the atmosphere to living organisms, dead organic matter, oceans, and back into the atmosphere, plays a significant role in balancing the greenhouse effect. As we continue on our current path, we risk further warming. The balance between sources and sinks of greenhouse gases is crucial for a sustainable future.
How can we reduce climate change in coral reefs?
The Great Barrier Reef is facing serious health risks due to insufficient global action on climate change. To save the reef, urgent global action is needed to reduce greenhouse gas emissions and strengthen key ecosystems like seagrass meadows, mangroves, and wetlands. These ecosystems absorb carbon dioxide from the atmosphere and store carbon, making the Reef one of the world’s most powerful blue carbon sites.
While emission reduction is crucial, we must also help coral reefs adapt to warmer temperatures caused by climate change. This is being done by developing and scaling up interventions that protect corals from bleaching, help them adapt to warmer temperatures, and actively rebuild resilient reefs.
How does carbon dioxide emission impact the coral reefs?
Ocean acidification represents a significant environmental concern, with 48% of global fossil fuel emissions absorbed by the ocean. The acidification of the oceans has a detrimental impact on the growth of reef-building corals, rendering them more susceptible to disease and the destructive forces of storms. Research findings suggest that elevated CO₂ concentrations can impede coral productivity and elevate the risk of bleaching events by up to 50%.
How do greenhouse gases affect coral?
Coral reef ecosystems are significantly impacted by climate change, which is primarily caused by factors such as burning fossil fuels, producing industrial products, raising livestock, fertilizing crops, and deforestation. Climate change leads to a warming ocean, which causes thermal stress, leading to coral bleaching and infectious diseases. Sea level rise may also increase sedimentation, smothering coral reefs. Changes in storm patterns, precipitation, and ocean currents can also cause coral bleaching and damage.
Ocean acidification, caused by increased CO2, reduces pH levels, affecting coral growth and structural integrity. To help, individuals can reduce their carbon footprint by driving less, reducing, reusing, or recycling, purchasing energy-efficient appliances and lightbulbs, and using less water.
How does reducing carbon footprint help coral reefs?
Coral reef ecosystems are at risk due to climate change, which can lead to coral bleaching and death. Carbon emissions also increase ocean acidity, affecting corals and their dependent species. To reduce carbon consumption, consider walking, biking, public transportation, and carpooling. Regardless of your location, every decision you make can impact a reef on the other side of the globe. Conserving water is crucial to reduce pollution, as all water winds up in the ocean and contributes to reef damage.
Runoff from water sources can carry nutrients and contaminants into the sea, affecting local rivers, coastlines, and lakes. Avoiding the use of pesticides, chemicals, and fertilizers can also help keep water clean. By reducing your carbon footprint and conserving water, you can help protect coral reefs and their ecosystems.

The sad thing is species have been dying on this rock for millions of years. We are creating an imbalance all by our little selves. Thats amazing. It means we can fix it. At the end of the day we are not worried about them. We worry about us existing w/ out them. I hope this all works out. Love the concept.
I been going to Cozumel Mexico with my best friend for over 30 years..at first it was sporadicly then about 20 years ago I was able to go yearly and the last 3 years or so I’ve gone twice yearly. We just went over Christmas and we were shocked at how many of the coral we see regularly along the shore had turned white. That scared me because we had been there in March and don’t recall seeing anything, I was heartbroken 💔. We haven’t been out to the deep reefs..the Columbian reef and the Palancar reef for a few years because we don’t dive. We’ve decided that the next time we go we’ll take a tour out and see how it looks. I pray that they are still healthy but don’t have a lot of hope. This beautiful island relies on tourism and we have gotten to know many of the locals so it’s hard when you know the people that are affected by these disasters. The vast difference in tourism from even 30 years ago to now is insane, on one hand I would like it to go back to the quieter island but on the other hand I am happy for the residents to have this income, for the reefs sake I would lone it to go back to the way it was.
I find it depressing that a few individuals, who possess billions, could with a fraction of their fortune (not here to discuss economics and the legitimity of it), make all the research easy and worldwide, as well as financing all the local action. But no, this money stays locked in a bank account and creates only percentage of revenue. So sad, as the crisis is so happening now. Anyway, thank you for this article!
2 years ago, I got my first betta fish. I fell in love with fish keeping instantly and soon upgraded from a 5g to a 10g, then a 20g, then a 29g. I eventually got my first reef tank and I knew instantly that this was my calling. I decided I wanted to start working with fish and coral preservation in the future. I planned out the steps to get there and although it’s a long journey, I’ve already taken my first step by working with coral at a fish store to learn more! Even though it’s a depressing science, coral is so vital for the future of the world and would be terrible to loose their beauty.
I feel sick about it. Yet as one small person, feel helpless, and that any/all of my efforts are futile. As someone who lives by the ocean, it baffles me that there aren’t more rules and regulations when visiting the ocean. Ie why, if you visit the beach for the day, is it not a requirement that everyone leaves with a bag of garbage they’ve picked up from the shore (it is mind boggling how much). That may sound stupid, and again futile, but it seems our massively important, life-sustaining oceans aren’t getting the respect and attention they deserve. Considering the health of the ocean balances life on earth, why aren’t we making this a number one priority VS, well, all the other stupid sh*t everyone is talking about (over and over again). My little opinion. I wish I could do more and i wish people could shift their focus onto this hugely important issue
Is flying tourists in airplanes, transporting them in cars and serving everything via plastic containers really helping? How many corals die from one person’s visit? The very people who claim to want to save these reefs are also contributing to their decline. It’s a multifaceted issue, yet they demand less emissions while literally flying people in on something that burns more fuel per second than literally anything else. Or the targeting of the beef industry while the same people own large numbers of pets. It’s easy to demand better of everyone else as long as you’re still getting paid. The hypocrisy is mind numbing.
You’re talking about the affected people? Dude, the affected people are the least important thing when it comes to corals. Imagine an acidic ocean, huh? The oceans are our planet’s most important heat sink. “The ocean absorbs about 90 percent of the excess heat produced as climate change warms the earth”. The corals are extrodinarily fragile organism. A tiny change in the ocean’s temperature has devastating effect on the corals. They turn white because the algae inside of it dies, and the coral spits out dead algae – turning white. After small while, the coral goes from whitening to rotting. The corals have been dying for the past decade (and that’s being very optimistic). “The Planet has lost at least half of its coral reefs Since 1950”. And corals don’t just regrow in a few years. “Depending on their size, barrier reefs and atolls can take from 100,000 to 30,000,000 years to fully form”. All life in the ocean is interdependent, and we talk about removing a whole habitat from such a fragile ecosystem, If you’re wondering “well, how is that gonna affect people”: well, guess what: “Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean”. Combine that with the melting of the poles. They reflect back a big part of the heat and are the reason for most of the ocean currents. Without glaciers, we got next to no ocean currents, which means that the oceans will just become a mass of static watter which will then turn more and more accidic (don’t even get me started on the plastic front).
Genetically modifying an organism is a very touchy subject but I’m not against it. I just think we’re using this on the wrong species. We should genetically modify the politicians, CEOs, directors and billionaire investors to be less corrupt, less selfish, less narrow-minded and less psychopathic. Doing only that will dramatically improve life on this planet for EVERY living thing including the coral polyps and the majority of human “mortals”
There are so many wrong things said in this. A lot of stuff is just not true. Algae do not give coral color. “Heat resistant coral” is non existent and you can’t selectively breed when reproduction is asexual. Also one coral benefits when it eats another coral, they fail to mention that there are corals for several different types of water levels, temperatures, and flow requirements. Also I saw acans in the “algae resilience” section. Acans are not reef building corals, no amount of acans will make a full reef. Lastly montipora and acropora have thousands of variants and are reef building corals they also grow extremely fast but require a lot of light in most cases. If the depth of the reef was lowered by just a few inches, the whole reef would be at a slightly lower temperature and certain less light requiring acro and monti could grow. Aka knock down some corals and place new ones there and move the old ones elsewhere. And also that whole thing about bleaching was not true. Corals bleach when they literally die. There’s another type of thing that looks like bleaching called polyp bail out, the coral leaves it’s exoskeleton behind. They described polyp bail out and then called it bleaching. If temperatures get too hot typically polyp bail out occurs, not bleaching. The coral Hopes to find a better location to grow by jumping ship. Unfortunately, other corals will attack it before it finds a good location. Last thing, corals can reproduce sexually, which is much more quick and results in far more genetic variation, why are we not doing more research on little known sexual reproduction of corals…
