Essay On Effects of Global Warming on Coral Reefs In English (100 Words)

The term “global warming” refers to an increase in the planet Earth’s climate’s average temperature. The atmosphere’s greenhouse gas emissions are raising the earth’s temperature. Coral reefs are impacted as a result of the oceans’ rising temperature.

Reefs of coral

The majority of the world’s marine ecosystem’s biodiversity is found in coral reefs, which also provide livelihoods for some 500 million people worldwide. More than a quarter of aquatic species are made up of them. Reefs offer a wide range of services, including food, assistance to the tourism sector, and flood protection. The loss of coral reefs will have negative effects on the economy, human health, and society.

Coral reef ecosystems are in danger from global warming. The world and oceans are warming, according to abundant scientific evidence. The high concentration of greenhouse gases in the atmosphere brought on by human activity is what causes climate change. Because of how much carbon dioxide they collect from the atmosphere, the seas have an impact on their chemical and biological processes.

Coral illnesses and coral bleaching episodes have greatly risen and are happening more frequently as a result of the temperature increase. Corals that construct reefs frequently die from coral illnesses. Many scientists think that the worsening water quality brought on by human-caused pollution and the increase in ocean surface temperature is the cause of the spike in mortality. Due to a sustained drop in seawater pH, carbon dioxide from the atmosphere has started to change the chemistry of the ocean, which has started to slow down coral reef calcification rates in reef-associated and reef-building marine animals. Ocean acidification is the term used for this.

The coral reef ecosystem will be further impacted by climate change due to rising sea levels, modifications in the frequency and intensity of tropical storms, and modifications in ocean circulation patterns. This will alter how the ecosystem works and how the coral reef ecosystem provides goods and services to people all over the world.

Coral reefs have adapted to climate change over thousands of years, but they might not be able to withstand the high temperatures. The remaining two-thirds of coral reefs are seriously threatened, and about 25% of them are damaged beyond repair.

The degradation and probable mass extinction of ocean corals is referred to as coral reef devastation. There are several factors that contribute to coral devastation, including pollution, unethical fishing practises, storms, earthquakes, and climate change, which raises ocean temperatures. Nearly half of the great barrier reef’s coral reefs have died, largely due to climate change.

Corals are living things, and they have the same potential for weakness, illness, and death as any other plant or animal species. Corals cannot endure the extremely warm water, which forces them to release the internal bacteria responsible for their vibrant hues.

Coral reefs are harmed by a number of factors.

Low tide, pollution, and global warming are all causes of coral bleaching. Low tide is also a contributing factor. Bleaching could get worse and happen more frequently in the future. Such bleaching incidents may cause irreparable harm to the coral environment and reefs, which are already under stress. If the corals are under constant stress, they become brittle, susceptible to illness, and may even perish.
Corals frequently perish as a result of plastics and other waste goods being thrown into water and getting stuck in the crevices of the reef.
Coral reef damage is partly a result of increased tourism. Coral reefs are harmed by recreationally used boats and ships. Other visitor activities like snorkelling and diving could unintentionally harm the delicate reefs.
Marine sediment is made up of insoluble materials that have been carried from the land to the ocean. Particles that are washed into the water from human settlements and other activities like agriculture, building, and mining can also be a factor. The coral reefs may become suffocated by the sediments, which also impede the flourishing of life by denying them nourishment and sunshine.

Climate change, or global warming, is the steady increase in temperature on Earth. The greenhouse gases emitted into the atmosphere as a result of human activity are the primary cause of the planet’s temperature and the ocean’s warming.

Degradation of the coral reef

Complex coral reef structures serve as the centre of active, biodiverse ecosystems. The survival of many marine species depends on their existence. However, as ocean temperatures rise due to global warming, algae that keeps corals vibrant and healthy are being killed or fragmented by high carbon dioxide levels. Coral bleaching is another effect of it. Numerous stressors, such as coastal development, overfishing, and coral bleaching, pose a threat to coral reef ecosystems. Coral reef ecosystems all across the world have been degraded throughout the years as a result of global warming and other pressures.

Hard corals are reef-building corals that have stone-like structures made of calcium carbonate. The calcium compound is also present in the shells of snails, clams, and oysters. Calcium is required for corals to produce their hard skeletons in seawater. According to research, larval colonisation on reefs with low pH values suffers by 52–73%. Recent research have shown that if global warming is not stopped, world-heritage reefs will perish under the stress of rising temperatures.

As a result of rising ocean temperatures brought on by global warming, coral bleaching has become more severe, which in turn has led to an increase in coral diseases. Coral bleaching events have a significant negative impact on more delicate coral reefs, like staghorn.

Sea level rise brought on by global warming has an impact on the ecosystem of coral reefs. The ecosystem of coral reefs is directly impacted by ocean acidification and is at increased risk. The intensification of the global hydrological cycle is accompanied by a continual increase in salinity at the tropical level. Changes in rainfall, storm frequency, and storm intensity also have an effect on the quality of the coastal waters. Intense storm systems and sea level rise increase the energy that waves exert on coastal regions, having an effect on coastal infrastructure, coral ecosystems, sea bottoms, and mangroves.


Marine ecosystems and creatures are responding in a variety of fundamental ways to the pace and scope of chemical and physical changes in the oceans that are occurring as a result of global warming. Temperature strains are taking over coral reefs more and more. Coral reefs cannot withstand extended or extreme stress, much like humans cannot. Since the effects of global warming on people and coral reefs are already severe, it is imperative to limit the amount of greenhouse gases released into the atmosphere.

The Great Barrier Reef is being impacted by rising ocean temperatures brought on by global warming, and the ecology as a whole may be seriously impacted. Temperature has a significant impact on the diversity and distribution of marine life. It is essential to creating coral reefs and reining in their expansion.

Coral reefs have expanded and adjusted to the limited temperature ranges just like other marine life. Thermal stress forces them to expel the algae from their tissues when the temperature rises above the average. Coral bleaching is brought on by this, and if it continues, corals may eventually starve to death.

The effects of rising temperatures on coral reefs are listed below:

The intensity and frequency of coral bleaching episodes increase as ocean temperatures rise. Increased coral diseases are another effect of warming waters.
Global sea levels could rise as a result of catastrophic ice melting brought on by warming ocean temperatures, which could have a negative impact on coral reefs. Because of the increased coastline erosion brought on by the rising sea levels, coral reefs may suffer from increased coral sedimentation.
Tropical storms have the potential to significantly harm coral reef ecosystems by seriously damaging the reef’s structure and creating more runoff from the land, which results in more sedimentation.
Ocean currents are impacted by changes in salinity, wind, temperature, and other environmental factors brought on by global warming. It may have an adverse impact on the temperature patterns, larval movement, and toxin transmission that harm thermally sensitive organisms like coral reefs.
Bleached corals are probably more susceptible to illness, have higher mortality rates, experience slower growth rates, and have less reproductive capacity. The animals that rely on coral communities for food, shelter, and habitat are impacted by changes in coral ecosystems. The makeup of the coral community changes when corals die from coral bleaching. When corals perish, there could also be a decrease in species variety.
The pace at which corals calcify is adversely affected by ocean acidification. Coral societies suffer as a result, becoming fragile and less resilient to the forces working against them. Coral habitat is becoming more and more limited due to chemical pollution in the oceans. Sometimes non-calcifying organisms take the place of dead coral when it dies.
The fate of the coral reef ecosystem will ultimately be determined by its capacity for recovery and resilience, as climate change may increase the disturbance regime of coral reefs.

Here is how we can contribute to lowering greenhouse gas concentrations in the atmosphere to halt additional damage to coral reefs:

Save, reuse, or recycle.
Reduce your driving, take public transportation, or carpool frequently.
Make use of energy-saving lighting and appliances.
As little printing as possible; prefer downloading.
Do not pour chemicals and household rubbish into drains.
Take part in beach and seaside cleanups as a volunteer.
The coral reefs and marine life are seriously threatened by the rising temperature. Rising sea levels, frequent flooding, and storms brought on by the severity would harm the coral reef system as well as the entire marine ecosystem. Controlling the temperature is urgently needed because it has already seriously damaged coral reefs. To ensure corals’ resilience in the event of a threat in the future, it is essential to protect the oceans as a whole.
