In the past fifty years, the Earth's glaciers have melted about 15%, and the Earth's climate has changed greatly as a result, but these changes have not yet affected the lives of ordinary people.
So what would it be like if one day all the glaciers on Earth melted? This is a scientific hypothesis, but unlike those wild scientific assumptions, it is a hypothesis that is likely to become a reality, and it does not require us to do anything to become a reality, just if we continue to maintain our current state, then one day the earth's glaciers will all melt. After all the earth's glaciers have melted, will there still be room for human beings to survive? There are still some. There are rumors that sea levels will rise by 1,000 meters after the earth's glaciers melt, which is pure nonsense. Some scientists have estimated that if all the Earth's glaciers melt, the sea level rise will be about 60 meters.
The melting of the Earth's glaciers will lead to sea level rise, but it is not only sea level that rises, but also land.
Why does the land rise? Because after the glacier melts, the sea level will rise, so the pressure on the seabed crust will become larger, and the pressure will lead to an increase in the density of the seabed crust, but the density gap between the oceanic crust and the land crust will become larger, so under the influence of rebound, the continental crust will rise and the terrain will rise. So the situation of inundation along the coast may be a little better than expected, but still more than half of the coastal cities will not escape the fate of being submerged. Speaking of submerging, looking at the world, Europe is definitely a hard-hit area, because there are a large number of coastal cities here, and the terrain itself is low, so it is difficult to survive.
If it is submerged by the sea, the Netherlands is the first to bear the brunt, because more than a quarter of the territory of this coastal country is below sea level, and a quarter of the territory is less than a meter above sea level, so when all the glaciers on the earth have melted, the Netherlands will cease to exist.
Compared with the Netherlands, the situation in other European countries may be slightly better, although many of the cities we are familiar with will become oceans, such as Venice in Italy and Paris in France, but after all, it will not be destroyed. The situation in the Americas is also not optimistic, most of the buildings in New York will be submerged under the sea, but you can still see that this is New York, because the 93-meter-high Statue of Liberty can also stick its arms out of the water.
Will the mainland survive?
Although we have the Qinghai-Tibet Plateau, known as the "roof of the world" and the highest mountain Mount Everest, there are also many low-altitude areas along the eastern coast, and in fact, it is not only coastal cities that are submerged, but also Beijing, Changsha and Wuhan that we are familiar with will become a vast ocean. If there is a better place in the world, it should be Africa. Overall, Africa is likely to be the continent least affected. Of course, submerging land is only one of the most intuitive consequences of glacier melting, but it is by no means the most serious disaster, because global climate change caused by glacier melting is the most dangerous, from ocean currents to atmospheric circulation, and then to changes in temperature will make the earth's organisms face great challenges, and most organisms will become extinct.
Humans would not have survived such a sudden climate change without modern technology and civilization, but human beings' existing technology and civilization could not solve all problems, such as viruses that may be buried under permafrost.
Life on Earth has been counted for billions of years since its birth, and in the long evolutionary process, what kind of viruses have been buried under the permafrost, no one knows, if the earth's glaciers all melt and the permafrost melts, these potential dangers will be released, maybe nothing will happen, maybe there will be disasters that are difficult for human beings to deal with, no one can foresee. Fortunately, all the melting of glaciers, rising sea levels, submerging land, and releasing viruses are all hypothetical, so we still have a chance not to let that happen.
Global warming is an old topic, it is difficult to arouse people's interest, and some people even think that this is a scam.
In fact, the same thing happened in 1975, when the scientist Bullerk rate raised the problem of climate warming, and said that the earth has been continuously warming, but it is not believed by people, until global warming really has a visible impact on the earth, people realize the original stupidity, the Bullerk rate is also known as the "father of global warming". Of course, the current general trend of global warming is irreversible, but we can try to delay the process of this trend as much as possible through our own efforts and seek a balance between development and the environment. In this regard, the mainland has also proposed to achieve the goal of "carbon peak" from 2028 to 2030 and "carbon neutrality" by 2060, as individuals, we should also do a good job in personal energy conservation and emission reduction in daily life, and contribute to the survival of the earth.
