How Does The Ocean Affect Climate Change – The oceans are already bearing the brunt of human-caused global warming, according to Climate Change. As the planet’s largest carbon sink, the ocean absorbs much of the heat and energy from increasing greenhouse gases in Earth’s atmosphere. Today, the ocean absorbs about 90 percent of the heat caused by global warming.
As the ocean warms with more heat and energy, temperature change leads to similar climate effects, including melting sea ice, sea level rise, ocean heat waves and ocean currents.

How Does The Ocean Affect Climate Change
These changes will ultimately have a lasting impact on marine biodiversity, livelihoods and livelihoods on the coast and beyond – including the 680 million people living in low-lying coastal areas. Nearly 2 billion people live in half of the world’s major cities located on the coasts. On the coast, almost half of the world’s population (3.3 billion) depends on fish for protein, and almost 60 million people work in fishing and agriculture worldwide.
Ocean And Climate Change
Sea level rise has accelerated in recent years due to increased ice melt in some regions of the world. The latest data from the World Meteorological Organization shows that global sea levels hit a new record in 2021, rising by an average of 4.5 millimeters per year between 2013 and 2021.
Along with the intensity of tropical storms, sea level rise has increased the risk of severe storms and coastal hazards such as flooding, erosion and landslides, which are expected to occur at least once per year in most places. Such things have happened once a century in history.
Additionally, the Intergovernmental Panel on Climate Change (IPCC) states that many regions, such as the Western Pacific, Southwest Pacific, North Pacific, Southwest Indian Ocean and the South Atlantic, are faced with higher sea levels. get up
Coastal heat waves have doubled in frequency and are longer, stronger and wider. According to the IPCC, human influence is the main cause of the increase in sea temperature observed since the 1970s.

Several heat waves occurred between 2006 and 2015, causing widespread coral bleaching and damage to reefs. In 2021, nearly 60% of the world’s oceans experienced at least one coastal heatwave. According to the Environment Agency, all of the planet’s coral reefs could be contaminated by the end of the century if the water continues to warm.
Coral bleaching occurs when algae lose essential nutrients when stressed. The latest global warming process began in 2014 and expanded significantly in 2017, extending to the Pacific, Indian and Atlantic oceans.
Rising temperatures increase coastal and marine vulnerability. Today, many changes have been observed, including the destruction of coral reefs and mangroves that support marine life, and the migration of species to higher and higher latitudes where the water can cool.
Latest estimates from the Educational, Scientific and Cultural Organization warn that more than half of the planet’s marine species could disappear by 2100. With a temperature increase of 1.1°C today , approximately 60 percent of the planet’s marine ecosystems would be affected. already damaged or in permanent use. Warming of 1.5°C threatens to damage 70 to 90 percent of coral reefs, while an increase of 2°C means a loss of almost 100 percent – a situation that could return.

The ocean plays a central role in reducing global greenhouse gas emissions. Here are some reasons why we must protect the ocean as the best partner for climate solutions.

) is very important for organisms that need calcium to grow, build, and maintain their shells and skeletons, such as certain types of plankton, oysters, crabs, clams, lobsters, and lobsters.
Sea levels make it difficult to maintain these structures. This can cause disruptions in food chains.

Warming and other stressors can also affect the resilience of corals, making it more difficult to build their calcium-based skeletons.
Marine conservation affects small coastal communities and large businesses. With the destruction of agriculture and tourism, communities that rely on the sea for food and income will be hit hardest.
It is estimated that up to three billion people whose livelihoods depend on coastal and coastal areas could be affected by ocean pollution. Large seafood factories are also under threat.
A study in the United States of America found that the country’s seafood industry could lose more than $400 million a year due to sea level rise by 2100. Researchers are studying this issue and companies are finding solutions to reduce the impact of marine erosion in the United States. fairy houses.
Climate Change Impacts
While it is important to develop adaptive solutions, it is also important to tackle the root of the problem: uncontrolled CO
In order to develop and implement solutions, it is important to better understand the biological effects of ocean pollution. Nuclear and isotopic methods, such as radiotracers, can be used as key tools to better understand these processes.
Facilitate this research, as well as encourage collaboration, coordination and communication regarding international projects on ocean acidification, established by the International Ocean Acidification Coordination Center (OA-ICC).
The Center brings together researchers and organizations from around the world to focus on developing scientific skills, as well as communication and communication, to promote a scientific approach to decision-making to solve this global problem. ? The various effects of climate change have modified the sea; these changes have greatly affected the reef ecosystem.
The Ocean And Climate Change
Climate change poses the greatest global threat to reef ecosystems. Scientific evidence clearly indicates that the Earth’s atmosphere and oceans are warming and that these changes are caused by greenhouse gases produced by human activities.
As temperatures rise, the incidence of infectious diseases increases. Additionally, carbon dioxide absorbed by the ocean from the atmosphere begins to reduce the rate of hardening of reefs and associated organisms by changing ocean chemistry by reducing pH. This process is called sea leveling.
Climate change will affect coral reefs, through rising sea levels, changing the frequency and intensity of tropical storms, and changing the ocean cycle. Taken together, all of these impacts significantly change how ecosystems are used, and the ecosystem products and services that people around the world benefit from.
Increasing greenhouse gas emissions due to human activities are leading to climate change and ocean pollution. Climate change = marine change. The world’s oceans are a huge sink that absorbs carbon dioxide (CO).
Explainer: How Does Climate Change Affect The Ocean?
Contributing factors that increase toxic gases in the air include the burning of fuels for heat and energy, the production of certain manufactured goods, the raising of livestock, the hardening of crops, and the destruction of forests. Climate change causes:
CONCLUSION ON CORAL POLLUTION Basics Most environmental stressors affecting coral reefs come from land-based sources, particularly toxins, sediments and nutrients.
ENDING ENDANGERED CORAL FISHING Many coastal and island communities rely on coral reef fishing, but overfishing can destroy key reef species and damage coral reef habitat. The planet’s oceans play an important role and currently absorb much of the carbon dioxide and heat produced by humans. But it’s also exhausting. Major changes are underway and the climate of our oceans appears unstable.
About 90% of the heat trapped by greenhouse gases is ultimately absorbed by the planet’s oceans. Due to the vastness of the oceans, the change in sea temperature is likely to be small: the sea surface has warmed by more than 0.5°C over the past century. Enough to cause a lot of trouble, and warming is accelerating.
Greenhouse Gases’ Effect On Climate
Materials expand as they heat up, becoming less dense and taking up more space. The oceans are no different. In fact, between 1993 and 2010, global warming is estimated to have caused sea levels to rise by an average of 1.1 millimeters per year, based on the total increase we’ve seen.
Total sea level rise during the period 1993-2010 was approximately 3.2 mm per year, with contributions from other sources including groundwater deposited on the land, such as snow. (Graphic: Manuel Bortoletti / China Dialogue Ocean)
Warm water also affects the upper atmosphere. Rising ocean temperatures are associated with more intense tropical storms and hurricanes, which may increase the number of extreme Severity 4 or 5 hurricanes.
