If the sea level rises by 100 meters: which of our first-tier provinces and cities will disappear? Which countries around the world are the worst off?

Experienced 2022 Arctic Circle can wear short sleeves of continuous high temperature, people really feel the global warming has indeed affected our normal life, the Earth's environment is becoming worse and worse.

If the sea level rises by 100 meters: which of our first-tier provinces and cities will disappear? Which countries around the world are the worst off?

With the worsening trend of global warming and the massive melting of the glaciers at the North and South Poles, human beings will not only have to face the torture of extreme weather, but also face an imminent problem, that is, "sea level rise".

So, if the glaciers melt and the sea level rises by 100 meters, which first-tier provinces and cities in China will disappear? Which country will be the worst off when you look around the world?

Sea level rise

More than 70% of the Earth is covered by oceans, so the changes in the oceans are closely related to the survival of human beings. Because of this, scientists are the first to focus on sea level changes when global warming is determined to be heading toward an increasingly dire situation.

In fact, according to current calculations and extrapolations, even if all the glaciers around the world were to melt, the sea level rise would be within 70 meters. In that case, a sea level rise of 100 meters is unlikely to occur.

Of course, we can not ignore the impact of some other factors, such as undersea earthquakes, the Earth's rotation stop, etc.. And here we discuss 100 meters as the limit, mainly to draw attention to, after all, if the value is not high, people will feel that "big trouble" not their turn.

At this point some people may say that the sea level rise does not seem to be as serious as the legend from the past few years, and maybe everything is just too much for people to think. But the reality is far more cruel than imagined, according to scientists' continuous tracking and observation, since the 20th century, the global average sea level rise rate is higher than a year.

However, this rate varies somewhat from region to region, for example, the rate of rise in Philippine waters is much higher than the global average, while sea level rise in the Pacific region off the coast of the Americas has a decreasing trend.

But in general, the global sea level is in the process of rising.

According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), global sea level has risen by an average of 10-20 cm over the past 100 years, with an average annual rate of rise of about 1-2 mm, and global sea level will rise by an average of 18-59 cm by the end of the 21st century and will continue to rise in the coming centuries.

Numerically, this increase seems to be nothing, but scientists are very worried about it. Because in terms of extreme weather in 2022, the future of the North and South Pole glaciers will face more extreme temperatures, and their melting rate is unlikely to remain within a certain value never change.

In this case, mankind may seem very far away from the catastrophe of sea level rise flooding the continents, but in fact may face this problem in a hundred years.

So, if the global sea level really rises 100 meters, what first-line provinces and cities in China will be directly submerged and become "Atlantis"?

After 100 meters of sea level rise

In order to prove the impact of sea level rise on the human world, there are people according to the height of the terrain and other conditions, specifically produced after the rise in sea level of different values, the sea gradually "encroachment" on the continents of the animation.

From this animation, we can also see that the first to suffer are coastal cities, and from the monitoring data of China's coastal tide gauge stations, the average rate of sea level rise in the coastal areas are different, the most obvious rise is the coast of Tianjin, Shandong, Jiangsu and Hainan.

Of course, this rate of rise only determines the order of inundation, many people have said that since the end will certainly be flooded, then the disaster occurred before the "overnight move" to Tibet. I believe that in the roof of the world above, or can avoid being attacked by the sea.

After the sea level rises to this value, Jiangsu Province will be the first to become a city under the sea because its average elevation is just too low. Even the highest mountain in the whole province is only 625 meters above sea level, so in the case of sea level rise, Jiangsu Province may become a "submarine province".

In addition, key first-tier cities like Shanghai will also suffer in the process of sea level rise. For this, I believe that we have seen in the "Wandering Earth", how the prosperous Shanghai is under the attack of the sea into a "city of ruins".

What about Beijing, another key region of the country?

In fact, not to mention the sea level rise of 70 meters or 100 meters, as long as the sea level rise of about 30 meters, we will be able to "see the sea" in Beijing. I believe that by this time, Beijing's housing prices will probably rise some more, after all, the suburban houses in Beijing will have been upgraded to sea view houses at this time.

There are also several provinces and cities, such as Tianjin, Dalian, Guangzhou, Zhuhai, and Shenzhen, that will disappear in the process of sea level rise. By then, the third step of China's three major ladders, basically can not be preserved, and with the increase in the height of sea level rise, the disappearance of the provinces will become more and more.

It is hard to imagine how many people will lose their lives in this disaster. And even if people have the foresight to move towards the higher ground, they will still face various chain reactions. In other words, not moving to the "Qinghai-Tibet Plateau" on top of everything will be fine.

So, apart from China where so many provinces will face such a crisis after a hundred meters of sea level rise, how about the rest of the world?

"The Vanishing State"

The first is our neighbors, like Japan, South Korea and other such low-lying island countries, in this disaster is certainly not immune. Even when the sea level has not yet risen to 100 meters, these countries will face the "extinction of the country", when they once existed traces will be erased.

The next look at the European region, like the Netherlands, Denmark and other countries basically all lost, and under the continuous encroachment of the sea, Europe will become "more fragmented". Those who still survive the land, may be a small part of a submerged country.

As for the North and South American regions, the United States, located in North America, will face a greater threat, and South America, due to the overall higher terrain, so the contours of the continent should still be preserved.

In general, the worst offenders in the sea level rise are actually the low-lying small island countries. These countries have now been affected by sea level rise, at that time, it is estimated that even "climbing on the high ground" the opportunity is not, directly wiped out.

Information shows that it is estimated that under a 1-meter sea level rise, Majuro Atoll in Uruguay, Egypt, the Netherlands, Bangladesh and the Marshall Islands would lose 0.05 percent, 1 percent, 6 percent, 17.5 percent and 80 percent of their land area, respectively."

Thus, countries like ours that have their backs to the mainland can still move people from lower coastal areas inland when faced with the disaster of rising sea levels. And these an island is "all" of the country, when there is nowhere to escape, can only watch their homes submerged by the sea.

If other countries are willing to accept refugees from these small island states, it would be fine, but in the trend of rising sea levels, we may all be "mud pusha crossing the river themselves", then it is estimated that there is little energy to promote the humanitarian spirit.

Of course, as we have said in the previous article, it is not a high plateau with high ground can continue to live normally. Because the impact of sea level rise is not only submerged land so simple, as the global ecological and climate system in the most critical link, the ocean once any change, other areas will make a chain reaction.

In this case, busy fighting the "sea" of mankind is expected to face famine, plague, extreme weather, sudden changes in temperature and other multiple dangers. Let's just say that when disaster strikes, humans will realize how small they are.

To sum up, in order not to let the sea water swallow our home, we should start from small things now to reduce carbon emission, so that the earth's temperature will not run towards more horrible direction again.

What we do may not prevent the disaster from finally coming, but it will buy future generations more time and give them a chance to escape!
