Pls who knows the impact of global warming on the oceans

Everything that has a calcium carbonate shell of a marine organism loses its shell.

The effects of sea level rise.

Over the past 100 years, sea levels have risen by 14 4 cm, and in our country by 11 5 cm. The main reason for the rise in sea level is the thermal expansion of the seawater, which rises when the ocean warms. Global warming causes the melting of icebergs at the Earth's north and south poles, which is one of the main causes of sea level rise.

Global warming will increase in marine typhoons.

It caused the enhancement of marine dynamics, inundation of low shoals, and aggravation of coastal erosion disasters. It has exacerbated seawater intrusion and soil salinization.

As a result of climate change, severe marine cyclones such as typhoons and hurricanes will increase dramatically;

Extreme weather phenomena.

In recent years, the rapid change of climate environment has led to frequent extreme weather events around the world, which not only cause significant economic losses to the world, but also repeatedly damage human health.

Glaciers melt. Climate warming.

The resulting changes in the ecological environment will force animals to migrate, resulting in the spillover of pathogens between animals and the increased probability of transmission to humans. In addition, the melting of glacial permafrost caused by climate warming may release frozen prehistoric viruses that can cause new unknown diseases.

The effects of ocean warming on marine life are as follows:

Global warming is forcing many organisms to find new habitats, but for benthic organisms such as sea snails, marine intestines and shellfish, finding a new home is not easy.

Heidi Fuchs, a marine biologist at Rutgers University in the United States, who has previously studied the spawning patterns and larval migration of sea snails, has found that the species of sea snails have been rapidly declining for decades.

When combing through data on other benthic marine invertebrates, Fox found that many species living in the same area had similar changes: they were moving southward as a whole, but their population ranges were shrinking as they gradually moved from deeper water to shallower places. But such a movement can lead to danger – warmer or even hotter waters are not conducive to the survival of these species.

Normally, benthic organisms in the mid-Atlantic spawn in late spring or early summer, and the average temperature in this area has risen by 2 times over the decades, which means that benthic organisms give birth about a month earlier than usual.

Fox and collaborators collected spawning and distribution records for 50 species from public databases, as well as studying changes in ocean currents on the continental shelf. The study found that currents were faster in early spring and then slowed down, and if a species lays eggs too early, its larvae may be carried further away by the currents.

Fox et al. also noted that as the ocean warms, cooler waters in the north are more suitable for southern species. The potential habitat range of most species has increased, but the actual range of species has shrunk by about 10% on average compared to the 50-80s of the last century. Among the species that are shrinking are important members of intertidal communities such as sand money and blue mussels.

At present, it is uncertain whether marine benthic organisms are in a similar situation on a global scale, and the impact of climate warming on the survival range of benthic organisms also needs to consider their spawning time and ocean current patterns.

For benthic organisms in the northern Atlantic, they may adjust their spawning times or evolve to tolerate warmer waters. However, some researchers have expressed skepticism that it may be necessary to consider transplanting the species into an environment that is more conducive to its growth.

Global warming is causing glaciers at the poles and high mountains to melt, and large amounts of fresh water are pouring into the oceans, causing sea levels to rise; As the temperature rises, the sea level rises due to the volume expansion of seawater.

Impacts: 1. Sea level rises, coastal lowlands are submerged, and some islands are shrinking;

2. The erosion of the sea is strengthened, and the estuarine delta will be inundated or eroded, affecting the construction of coastal ports;

3. When the salty tide occurs in the coastal area and the sea level rises, when it is higher than the water level of the groundwater or the estuary of the river, the seawater is being instilled and the salty tide occurs;

4. Affect fishery production;

1) Sea level rise.

History proves that in the 20th century the global sea level rose by 10 15 cm. Based on the current rate of greenhouse gas emissions from human activities, it is estimated that sea levels will be higher by mid-century than they are today. The direct impact of sea level rise is as follows:

The lowlands are flooded; Coasts are eroded; poor flood drainage; land salinization; seawater inflow, etc.

Currently, about 1 3 of the world's population lives within 60km of the coastline, and 20 of the world's 35 largest cities are located along the coast.

2) Effects on flora and fauna.

Plants and animals have responded to historically slow climate change, either adapting to or becoming obsolete. Those who exist are adaptors, but they only adapt to the slow changes that have occurred in the past over many centuries. For example, since the late Quaternary Ice Age, the surface ice retreated northward, and the temperature rose for thousands of years5, and the oak forests of the southeastern United States gradually migrated northward.

Due to anthropogenic CO2

The scale of climate warming due to increased emissions is similar to the above, but it has occurred in a century. During this period, the climate zone warms and moves hundreds to thousands of kilometers to higher latitudes. However, the flora and fauna of nature, especially plant communities, may be doomed by the inability to adapt and transfer at a commensurate rate.

Climate scenarios at CO2 doubling estimate that the southern boundary of North American forests will retreat 600 700 km to the north. However, based on the historical rate of forest migration, even if it were doubled, the northern edge of the forest would only move north by 100 km in 100 years. Future climate change will cause some species to disappear in some areas, while others benefit from warming, with more habitat and fewer competitors and predators.

and 3) the impact on agriculture.

Preliminary studies suggest that global warming will cause a northward shift in the temperature zone, which in turn will lead to a corresponding change in atmospheric motion, and a consequent change in global precipitation. In general, such an increase in temperature leads to an increase in potential evaporation and a weakening of the meridional circulation, with increased precipitation in the existing rain bands at lower latitudes, more snowfall in winter at higher latitudes, and less precipitation in summer in mid-latitudes. Increased precipitation is beneficial for most dry and semi-arid regions, but for areas with reduced precipitation, such as central North America and inland northwest China, it will become more arid due to reduced summer rainfall, leading to desertification.

In addition to this, global warming will also exacerbate natural disasters such as high temperatures, heat waves, tropical storms, and tornadoes. As a result, the stability and distribution of world food production will change significantly as global temperatures rise. Warming temperatures have caused changes in the structure of agriculture, which will lead to corresponding changes in the patterns of many agricultural products.

4) Effects on human health.

Global warming will cause increased morbidity and mortality in humans, and infectious diseases such as schistosomiasis and dengue fever will endanger many areas.

As we all know, the environment and temperature of the earth in which we live are undergoing particularly drastic changes. Once upon a time, temperatures on Earth were relatively stable, with few warm winters. Over time, the temperature on Earth has changed particularly dramatically, a phenomenon that is closely linked to global warming.

Global warming causes glaciers to melt and sea levels to rise. In the long run, people living in coastal cities will be affected, while marine and terrestrial life will be affected by both temperature and environment. We must not think that global warming is not directly related to everyone, but it is not true, and we can reduce the rate of global warming through our own actions.

Coastal residents are known to enjoy particularly good weather and environment, so the first destination for most people is the coastal city. In fact, coastal cities are also at risk of global warming, which could inundate some coastal cities if the rate of global warming accelerates, increasing the amount of glacial meltwater in the oceans, and the melting of Antarctic and Antarctic glaciers at an increasing rate. At the same time, organisms living in the oceans and on land are unable to adapt to the environment on which they depend due to changes in temperature, and a large number of marine and terrestrial organisms have passed away, and biodiversity and the number of organisms have declined dramatically.

In order to ensure that global warming does not affect too many residents and cities, most countries will carry out various activities to prevent global warming, especially the measures and activities carried out by China to reduce carbon emissions. Only by understanding the causes of global warming can people be able to prescribe the right medicine, and carbon emissions are one of the important causes of global warming. In addition to China's efforts to reduce carbon emissions, most of its residents also have the idea of protecting the planet.

When the world's inhabitants are able to participate in the fight against global warming, people will be able to enjoy a better future and blue skies and white clouds.

In general, global warming will cause particularly serious harm, with a sharp decline in biodiversity and the inability of most organisms to adapt to the rapidly changing global environment. In addition to this, glacier melting is one of the manifestations of global warming, and after a large number of glaciers melt, glacial water enters the ocean, thus increasing the height of the ocean. Everyone should do a good job of protection, and never think that global warming has nothing to do with them.

In life, individuals must reduce carbon emissions and prevent the destruction of the ozone layer.

In the long run, many animals living in the deep sea may be affected, and many fish that are afraid of heat will die as a result, so some uncommon fish may disappear from our earth. In the long run, it will also be very dangerous for our human life, and there may be some animals with genetic mutations.

In the long run, it can lead to problems with marine life, and then the ocean is not suitable for marine life, so that they don't have a home, and it will also lead to global warming, and then the temperature will get higher and higher, and some glaciers and icebergs and things like that will melt, and our environment will be very poor.

This could lead to the melting of glaciers, the possibility of rising sea levels, the severity of the greenhouse effect, the breaking of biological chains, and the possibility of affecting human survival.

Affecting the survival of organisms on the earth will lead to the extinction of many species, and will also affect the ecological balance, and the inability to produce enough oxygen will lead to hypoxia, which will lead to the extinction of human beings.

Introduction: In fact, most of the earth's surface is ocean, and only part of it is land, so marine ecology is very helpful for the regulation of the entire ecosystem, and there are many organisms living in the ocean. What are the dangers of ocean warming? What do you think?

First of all, the temperature of the sea water is relatively fixed, of course, due to the different latitudes of the ocean, the sea temperature will be lower at high latitudes, and the sea temperature will be higher at the middle and low latitudes and near the equator. However, as the temperature of the sea changes, there are marine organisms that can adapt to that temperature, and the deeper the water, the more stable the temperature is. When the ocean warms, there are a lot of marine creatures that can't stand it, and these creatures may die because of the warming of the water.

And when the sea warms, the microorganisms in the ocean begin to become active, and at this time, there will be a microbial bloom, and the microbial multiplication will consume the oxygen in the water, aggravate the death of fish, and thus form a red tide. Therefore, ocean warming will seriously damage the marine ecosystem, and it will have a serious impact on human fisheries. In addition, the temperature regulation of the ocean plays a very important role in the global temperature regulation, and when the ocean warms, the global temperature is actually changing.

Low-carbon living is what everyone should do, and it can be done in daily life, and ultimately it is necessary to develop good habits, so that more people can feel the benefits of low-carbon life. In your daily life, try to take public transportation instead of taking a private car, and buy an electric car if you can afford it. In addition, you can cook and eat together as a family during normal times, so you can reduce your carbon emissions when you go out to eat.

In addition, we should learn to recycle in our daily life, and don't always buy things, so that we can avoid the waste of resources, which are good habits for low-carbon life.

The harm is that it may lead to the death of fish, may lead to the reproduction and development of fish, can also lead to the decline of fish population, and can also lead to some fish diseases. My view is that we should protect the oceans in time, reduce fishing, and alleviate the crisis of ocean warming, so that the oceans can develop better.
