What is the harm of rising sea levels to the earth?

1. There is no harm to the earth.

2. It is harmful to the current human environment.

1. Sea level rise is a slow-onset natural disaster for human survival and economic development. It is precisely because it is slow to develop that people often do not pay attention to the fact that a millimeter of rise per year does not pose a danger.

2 In fact, such disasters are cumulative and gradual. For example, if millimeters are now added every year and every decade, sea levels will rise by centimeters in the first decade of this century, centimeters in the second decade, and centimeters in the last decade. By the end of the century, global sea levels will rise by centimeters.

3 This is undoubtedly devastating for people in many places. And even now, it has brought harm to the people living in coastal areas. It makes the occurrence of disastrous storm surges in coastal areas more frequent, aggravates flood disasters, erodes coastal lowlands and coasts, retreats coasts, pollutes water in coastal areas, salinizes farmland, increases tidal range, strengthens wave action, weakens the ability of coastal protective dikes, forces designers to improve engineering design standards, increases project funding, and will also aggravate the seawater intrusion of estuariums, increase the difficulty of sewage discharge, and destroy the ecological balance.

Sea level rise is caused by melting glaciers, polar bears.

The area of glaciers where penguins live will be reduced, which will increase group competition between races and compete with other species for territory. Insufficient individual survival resources will trigger the group self-destruction mechanism. If you don't consider the consequences of the disaster, because the whole world is affected by the disaster, many countries and regions are gone, such as the whole of Eastern Europe.

Most of Russia's rich regions, the western United States, and Australia lost all their cities.

Sea level rise is a fact in the global scope, and as the sea level rises by 100 meters, our countryMiddle EastThe big cities along the coast are basically in the ocean, for example, if you rise 4 meters, Shanghai will be flooded, and if you rise 6 meters, Guangdong will be affectedWe might as well take a look at the three northeastern provinces if the sea level really rises by 100 meters.

How about the three provincial capitals.

Harbin, Shenyang, Changchun, the altitude is 148 meters, 55 meters, 241 meters respectively. So Shenyang is definitely going to be submerged. Yunnan-Guizhou, Qinghai-Tibet Plateau.

Some areas are inhabitable for humans, but they cannot accommodate 1.4 billion people. The global population will be reduced by more than 90%, what a terrible harsh environment, the protection of the environment starts from me, we must not ignore the changes in the harsh environment, everyone is responsible for protecting the environment.

This can be said to have a very large impact on the earth's sea level, scientists have warned again, preliminary estimates, by 2100, about 400 million people will be directly affected by climate extremes, so it is necessary to carry out climate governance as soon as possible.

the Arctic and Antarctic ice sheets, as well as Greenland.

and Iceland with mountain glaciers, the largest of which is the Antarctic Ice Sheet, with an area of 1,398 square kilometers, accounting for 98% of the Antarctic continent, with an average thickness of 2,500 meters and a total volume of 24.5 million cubic kilometers, accounting for 90% of the land ice! The average height of the land rises and falls, and the average height is 875 meters, while the plains below 200 meters above sea level account for about 1 3 of the total land area. It follows that if sea levels rise by 100 metres, many parts of the world will be wiped out.

It is very likely that other creatures will slowly die in the sea, because this situation of sea level rise is likely to cause many animals to be unable to live and breathe normally.

Sea level rise is caused by global warming and melting polar glaciers, which will lead to frequent natural disasters in coastal cities, serious soil salinization in coastal areas, and even exacerbate storm surges.

Rising sea levels will change the land and sea, new species will appear, some existing species will disappear, and the environment in which humans live will change.

1. Inundation of land: Nearly 70 coastal zones around the world, especially the vast low-level delta plains, will become a country, and the sea water can invade twenty or thirty to fifty or sixty kilometers, or even beyond. 2. Erosion of the coast:

When sea level rises, the dynamic effect of the ocean will intensify, which will increase coastal erosion, especially the sandy coast. 3. Seawater intrusion: The evil consequence of sea level rise is seawater intrusion, which causes the water quality of coastal areas to deteriorate due to the rise of groundwater level, and the ecological environment and resources are also damaged.

4. Increase the frequency of marine natural disasters: Sea level rise will also increase the frequency of marine natural disasters, such as typhoons, heavy rains, storm surges, etc. 5. The sea flow field changes, washing away the sand: the original beautiful beach bathing beach has become a pebble beach.

Sea level rise is a global phenomenon caused by global warming, melting polar glaciers, and thermal expansion of upper seawater. Global sea levels have risen by 10-20 centimeters since the 20th century, making it a slow-onset natural disaster.

Rising sea levels can inundate some low-lying coastal areas, increasing the intensity and frequency of storm surges. As a result of global warming, sea levels will inevitably rise by at least 1 metre in the next 100 to 200 years.

Third, the global crisis has intensified. Rising sea levels can exacerbate conflicts between regions and countries, due to resource constraints and increased social contradictions. Conflicts and contradictions between countries and regions will occur frequently, and wars may even break out in order to compete for limited resources.

There has been a significant increase in instability between regions. Social contradictions are intensifying day by day. The world is facing a new crisis.

Are you worried about rising sea levels?

Rising sea levels will inundate human cities near the sea, increasing sea levels and reflecting too much sunlight, causing the earth's temperature to drop.

The living space is shrinking. Rising sea levels will inundate land, which will be a catastrophe for low-altitude countries, and they will have to be relocated.

Rising sea levels will cause coastal areas to be submerged, and there will be less and less room for people to survive.
