The world's sea level is the highest or rises by 66 meters. What will happen to the world and China?
If all the glaciers on the earth melt and flow into the ocean, the highest sea level will rise by 66 meters. Compared with Mount Everest, this height is really just the tip of the iceberg. The "toes" of Mount Everest may not be submerged at all. , so it doesn't matter at all.
But this 66-meter rise will engulf many countries in the world, completely change the appearance of continents and coastlines, and the territories of many countries will enter the seabed.
At the same time, many countries on land will shrink, so our oceans will expand further, and land will shrink again. Of course, compared with Mount Everest, there is no major change at all. At most, the glaciers on the top of the mountain are gone, and the climate has changed. This is the situation of all the glaciers on the earth melting, and the maximum rise is 66 meters.
What would the world look like if the sea level rose by 66 meters?
As we said above, it will definitely lead to large-scale inundation of cities, changing continents and coastlines, and judging by the 66 meters of sea level rise, if this happens, then the entire Atlantic coast of the United States will disappear, Florida and the Gulf Coast region will cease to exist.
The hills in San Francisco would become islands, and San Diego would disappear forever. And most of China and Bangladesh will be submerged, and the Amazon plains and the Paraguay river basin will become the Gulf of the Atlantic Ocean.
In the African region, Alexandria and Cairo in Egypt will both be flooded and become water cities, so the world's pattern will definitely change dramatically. This is a non-controversial issue. Therefore, from the perspective of satellites, the world will see the earth more like a water polo. Of course, this may be the case when the sea level rises by 66 meters without calculating any circumstances.
When life on earth exists, the water part of the melting glaciers is also used by humans, and there must be a part of the loss, so the data is expected.
What will happen to China if the sea level rises by 66 meters?
For such a high sea level, as we mentioned above, most parts of China will also be submerged, among which the coastal cities in China may be submerged the most. We can see from the average altitude that the sea below 66 meters There are many areas with a high plane height, and large cities such as Shanghai and Guangzhou are unavoidable. Therefore, the rise of the 66-meter sea level will turn many inland areas into coastal cities. Take a look at this data.
According to a data provided by the Institute of Environment of Tsinghua University, if the earth's sea level may rise by 66 meters after the global iceberg melts, the ocean will submerge more than 1 million square kilometers of China's most economically developed area with a population of more than 600 million. Therefore, the impact of sea level rise on human beings is very huge. It seems that many areas have become sea-view houses. In fact, this is a catastrophic impact on human beings. So some people are good and some people are not good, but overall, sea level rise has more adverse effects.
Therefore, whether from our own perspective or from our global perspective, sea level rise has a major impact on human beings, especially for today's developed cities. It is really a big impact. The maintenance cost of sea level rise is getting higher and higher, and natural disasters such as storm surges caused by sea level rise are getting stronger and stronger, so scientists are now feeling headaches about this.
Why are sea levels rising?
This reason should be known to everyone, that is, it is caused by global warming, and global warming is related to human beings, so in the end, it is because of human beings that the sea level rises. Under the influence of human activities, the increase in the The emission of greenhouse gases has affected the continuous warming of the earth, including today. Humans see that global warming is still obvious, and this year may continue to be the hottest year, which also means that the melting of glaciers is still accelerating.
Therefore, in general, temperature is the main factor affecting sea level rise. This year, due to the extreme high temperature in the Arctic Circle, it has also led to a new low of "remaining" sea ice, and now the rise in temperature is still causing permafrost. The accelerated melting of soil increases the secondary warming effect.
So the planet is getting warmer at an accelerating rate, and that's the main driver of sea level rise, not because of the rise and scientists don't get headaches.
Therefore, the World Climate Center is calling for reducing greenhouse gas emissions every year, planting more trees, cutting down less, and strengthening the evolution of the climate. It is also to reduce the occurrence of extreme climate phenomena, so as to ensure the stable development of our earth's temperature. If it continues , which may eventually lead to more difficult human life, which is the impact of sea level.
