    Many developed countries.

    Proximity to coastal cities. Because it can be promoted with other countries**, transportation is more convenient. After the sea level rises.

    66 meters, which city in our country will enter the ocean? Scientists have given us simulated data, and many cities will suffer when they see this data.

    When the sea level rises by 10 meters, the coastal zone of Jiangsu, especially Lianyungang, and parts of Shandong have entered the depths of the ocean. Including Qingdao and other places, if you look here, you will find that many friends are in a panic. I didn't expect the sea level to rise by only 10 meters, which would have such a big impact on our country.

    When the sea level rises by 20 meters, it will continue westward to Nanchang.

    After the sea level rose by 30 meters, China's Wuhan, Yueyang, Jinan, Texas.

    and so on began to swallow. Sea level rise of 40 meters, Jining, Shandong.

    Liaocheng and Shenyang in the northeast are flooded, and the sea level has risen by 66 meters, and we can see that many cities, including our southern region, are flooded, and if the sea level rises to 60 meters, China's coastal cities are basically its sphere of influence. It is possible to know which city is below 60 above sea level from the height of the city, but this data is only the average altitude data, so the actual impact will be much larger than the city shown in the data. For example, the average elevation of Xiamen is 63 meters, and it seems that nothing is happening.

    This is not the case. There are many mountains in the Xiamen area. The height belongs to the large terrain, and the altitude of many areas in Xiamen is only 10 meters.

    Again, the average height of Nanning is 72 meters, and in fact the sea level rises to 60 meters, and most of the cities of Nanning will be submerged. Qingdao, Shijiazhuang, Dalian, Fuzhou and other places.

    China's major cities with an average altitude of less than 60 meters include Beijing, Shanghai, Guangzhou and Shenzhen.

    and big cities such as Tianjin. In addition, Taiwan Province of China.

    It was also greatly affected. Taipei City.

    Located in the northern basin, with an average elevation of only 9 meters, it may be completely submerged by water. The average altitude of Beijing is about meters, the average altitude of Shenyang is meters, Jinan meters, Wuhan meters, Nanchang meters, Nanjing 28 meters, Guangzhou 11 meters, Hefei meters, Macau 33 meters, Taipei 9 meters, Fuzhou 14 meters, Hangzhou 14 meters.

    If the sea level rises by 50 meters, many lowlands in the world will be submerged, and the land area of the world today may be reduced by more than half, and our north, Shanghai, Guangzhou, and Shenzhen will definitely be submerged, and some provincial capitals on the eastern plains are also easily submerged, and Jinan, which has Shandong, has stopped close to the inland, but its altitude is only more than 51 meters.

    The climate is becoming more and more severe, and rising sea levels have become an established fact. Once it rises to a certain level, Shanghai will definitely be submerged. Because when the sea reaches 60 kilometers, the original ecosystem will be completely overturned.

    If humans don't do anything to protect their homeland, they may end up reaping the consequences. Everyone has to pay a price for their actions, and think about why they are burning fossil fuels and destroying the grassland environment. Once a large amount of carbon dioxide is emitted in the air, it will definitely affect the environment.

    The global population is constantly increasing, and people choose to raise a large number of cattle, sheep, chickens, ducks, etc. to meet their needs for meat and protein. In terms of the proportion of cattle and sheep in the world, India has 300 million cattle. Known as the country with the most cattle in the world, Australia is home to more than 200 million sheep.

    Once more is raised, the greenhouse effect will become more and more obvious. When all the animals live together, the farts become methane. <>

    There are two reasons for global sea level rise, mainly in the following two ways. Clause.

    1. The glaciers, snow and ice in the polar regions have all melted, and all the excess water has flowed into the ocean. As the water becomes more abundant, the sea level will definitely rise gradually. Clause.

    Second, the phenomenon of global warming has become increasingly obvious, and the warming of sea water will definitely cause the expansion of water bodies. In the face of global warming, the relevant departments must respond in a timely manner and not allow innocent people to be harmed. <>

    In general, sea level rise and subsidence will have unavoidable effects, and it is important to know what the risks are stacked within. The relevant departments must strictly demand that human beings take action to strengthen energy conservation and emission reduction, so as not to cause greater danger to sea level rise. Inland areas are relatively high from the sea and can be alleviated, while low-lying areas are difficult to escape the claws, and the consequences are very serious.

    Zero CO2 emissions must be implemented to slow down urban subsidence. Otherwise, once Shanghai is submerged, the social development of mankind will certainly be seriously affected.

    Rising sea levels can inundate some places at lower elevations. As the sea level rises, some coastal cities will be submerged, cities will be destroyed, humans will not be able to survive and develop normally, animals will not be able to survive, and there are many cities like this.

    Global warming, rising temperatures, melting snow and ice leading to sea level rise, and the annual increase in global average sea level is very small and negligible.

    If global temperatures continue to warm and Antarctic and terrestrial mountain glaciers begin to melt, the sea level rise in 100 years will theoretically be only 200mm, which will not inundate Shanghai. The average sea level in Shanghai is 4m = 4000mm, and the sea level that has risen in 100 years is only 1 20 above sea level now.

    So rising sea levels are not going to flood Shanghai now, and if they do one day, it will be a long, long time away.

    1.Sea level rise is a global phenomenon of sea level rise caused by global warming, melting polar glaciers, and thermal expansion of upper seawater.

    2.Global sea levels have risen by 10-20 centimeters since the 20th century, a natural disaster that occurs slowly. Rising sea levels can inundate some low-lying coastal areas.

    Increase the frequency of storm surge intensity. Global warming will cause sea levels to rise by at least 1 metre over the next 100 to 200 years.

    As we all know, sea level rise is caused by the melting of Arctic and Antarctic glaciers due to global warming, and if the sea level generally rises by seven meters, these cities I have passed may be inundated, such as Shanghai, the altitude of Shanghai is 6-7 meters, and if the sea level rises by seven meters, Shanghai will be submerged, and there are coastal cities such as Guangzhou, so in order to protect the environment I live in, we must take active measures to prevent global warming and prevent sea level.

    If the sea level rises by seven meters, most of the land will be directly submerged, and the cities in China's coastal areas will inevitably be submerged, because the coastal areas are plains, the terrain is low, and cities such as Shanghai and Xiamen will become history.

    Sea level rise is a serious topic. The sea level does not rise too much, so maybe a dam can be built to hold back the tsunami and withstand it for a while. But for those who live on the island, they may not be so lucky.

    A few decades ago, someone patted them on the forehead and came up with a theory called the greenhouse effect. This is because global warming has led to a rise in the snow line, retreat of glaciers, and a series of environmental problems such as desertification.

    In fact, the biggest problem with the greenhouse effect theory is that it does not explain clearly where the snow on the snow-capped mountains comes from? Where does ice in glaciers come from? It can't be that the snow grew out of the ground on its own, right?

    Snow on snowy mountains, ice on glaciers. In fact, during the summer months, large amounts of seawater in the equatorial region evaporate to form water vapor, which rises into the air to form tropical storms, which then push to the continent and into the depths of the continent, where it rains and snows. In this way, the land on land is moistened by rain, and the snow-capped mountains can be replenished in a timely manner, which also brings a supply to the ice in the glacier.

    Why is sea level rising? That's because the way water vapor in the ocean pushes toward the continent is artificially blocked. Because the world is frantically developing coastal areas, a tight reinforced concrete windbreak wall has been formed in the coastal area, and there are various landmarks that disrupt the smooth flow of water and air.

    In this way, the water that flows into the sea from the interior can no longer return to the mainland and the depths of the continent. Naturally, sea levels continue to rise. Because without water vapor recharge, there will not be enough rainfall and snow on the continent, and drought and desertification will come.

    The snow on the snowy mountains only melts and is rarely replenished, so the snow line rises, and the ice in the glacier only melts and is rarely replenished, so the glacier retreats. Because rain reduces the dust in the air and cannot be washed away, smog is formed. As for the coastal areas, due to the windshield and landmark buildings, many water appliances hit the windshield and landmark buildings, becoming precipitation in the coastal areas, causing a lot of heavy rain and flooding.

    For the coastal zone, of course, it will also be affected by sea level rise, but due to the construction of the sea embankment and the depth of the land, it will be flooded a little, but not too much. If the sea level rises within a certain range, the climate temperature on Earth will remain within a certain range and operate naturally. When the sea level gradually rises to a certain limit, climate changes, flash floods, heavy rains pour, and the entire earth is flooded.

    Rising sea levels are likely to flood the coasts; Rising sea levels, melting glaciers, thermal expansion of the oceans, increasing flow of water from rivers into the oceans, and subsidence of the ground in coastal cities can all contribute to sea level rise.

    The first point is that the main cause of sea level rise is due to the melting of glaciers, and the other point is that if the sea level rises, many island countries will be submerged by the sea, because the island countries have no resistance to these sea level rises. If the global sea level rises, it will also lead to a decrease in the global continental area.

    I think that if the sea level continues to rise, it will inundate the coastal areas; Global temperatures are warming, glaciers are melting, sea waters are beginning to thermally expand, desertification, heavy rains and floods.

    At an altitude of 0 meters, if there are some places along the coast, they will be submerged by the sea due to the rise in sea level, and in inland places, they will not necessarily be submerged.

    The main reasons for sea level rise are: 1. The sea temperature rises. 2. The flow of water flowing into the ocean from rivers increases. 3. Melting glaciers. 4. Thermal expansion of the ocean. 5. Land subsidence in coastal cities.

    From 1980 to 2010, the average global temperature increased every 10 years. And due to the melting of ice sheets and glaciers, sea levels rose by millimeters per year between 2005 and 2010. Scientists say that since 1993, half of the sea level rise has been caused by the thermal expansion of the oceans, while the other half is due to melting glaciers.

    The oceans are warming by about 27 degrees Celsius by absorbing heat from the atmosphere, which is the main cause of sea level rise.

    In some coastal areas, especially in the estuary, the urban geological structure is mainly muddy and sandy, which is not strong enough and has a certain compressibility. The rapid development of the regional economy has led to a relative rise in sea levels due to the overexploitation of groundwater and the increase in large building clusters that have accelerated land subsidence due to ground loading.

    The acceleration of sea level rise has been, or will be, a major disaster in the coastal zone. In the past 100 years, the world's sea level has risen by an average of about 12 centimetres in the past 100 years, and in about 2100, Tuvalu will be in danger of inundation by 1 metre. If protective measures are not taken, large areas of land and many coastal cities will first be flooded.

    It is necessary to be able to pay attention to one's own behavior, take care of the global environment, and prevent the deterioration of global warming. In recent years, global warming has led to rising sea levels, and many countries may even disappear from the planet. These topics have become topics of high social concern, and if human beings did not pay attention to them before, people have realized the seriousness of the problem at this stage.

    Rising sea levels due to global warming have left many scientists worried about land area. When the situation is severe, it can cause the entire land area of the planet to be turned upside down. On the face of it, the impact of this situation on the inland is relatively small, but the impact on coastal cities or countries is large.

    Tier-1 cities such as Shanghai and Beijing are very prone to inundation when the sea level rises further, and the situation is very serious.

    If we look at the recent reports, the current sea level rise rate has exceeded human imagination, and it is even more terrifying than many scientists estimated. It is not difficult to see from the analysis of the data situationThe large-scale warming of the earth's temperature directly leads to the accelerated melting of polar glaciers, which in turn causes the coastal areas to slowly subside. According to the monitoring data, the distance of sea level rise in coastal areas is 2.6 millimetres per year.

    Among them, the height of subsidence near the delta is more pronounced, and the overall sea level rise or coastal area has fallen more than expected.

    In addition to the rapid melting of glaciers leading to sea level rise, sand mining, dam construction and oil extraction are the main factors for the rapid sea level rise. When all these major factors are combined, the overall sea level rise is more than four times faster than scientists expected. Including China's current sea level situation, it is also on an upward trend, and even domestic scientists have issued serious warnings that after this deterioration, low-altitude cities such as Shanghai in China and New York abroad will face engulfment in the future.

    In order to cope with the further occurrence of the consequences, countries around the world are trying to change the warming of the environment and reduce greenhouse gas emissions in order to fundamentally mitigate the further rise of sea levels. Of course, in this case, even if it does not completely alleviate the rise in sea levels. It is also necessary for humans to stop any actions that harm the environment so that sea levels do not rise faster.

    Overexploitation of the surface of groundwater appears to have very little impact, as it can be partially replenished after the rainy season. However, if you look at the long-term situation, the impact on human survival is very large. Overexploitation of groundwater can easily lead to land subsidence, which in turn causes land area to be flooded, threatening the better survival of human beings.

    Only by strictly controlling the exploitation of groundwater can the phenomenon of land subsidence be avoided.

    In short, global warming and rising sea levels have become an indisputable fact. In this case, what human beings should do is to pay attention to their own behavior and take care of the common home of mankind - the earth, in order to continue to survive well and continue their civilization.
