22 people know that high -temperature people glorifierated in many places in the glorious land. The extreme high temperature caused humans to worry about global warming .
, however, the sustainable development of global warming on human beings is not limited to high temperature effects, as well as extreme rainfall, glacier melting - sea level rising and other problems.
is not. In 2022, the Antarctic "Doomsday Glacier" has changed significantly, and its melting speed has increased. Once the glacier melts, it may inevitably lead to the rise of the global sea level, which will bring threats.
is also published in satellite survey, and it is also published in " Natural " magazine. After many people see the large -scale melting of the Antarctic "Doomsday Glacier", they gradually worry about their threats to China, which is undeniable.
As long as the global warming continues to develop and the large -scale melting glaciers will have an impact on the rise of my country's sea level. Under the condition of the whole melting of the "Doomsday Glacier" alone from the Antarctic ", Become a underwater city. How serious is it? Let's take a look at the situation.
Antarctic Ice Glacier is abnormal, accelerate melting
, in fact, everyone should not be surprised to see this news. After all, summer high temperature in 2022 is very common. The Americas and other places still appear High temperature above 50 degrees.
is not. In September, the United States encountered nearly 53 degrees of high temperature attacks, which directly broke the highest temperature record in the world in September. Therefore, this also reversely illustrates a problem, that is, the heating of the earth caused extreme climate phenomena to appear on a large scale. At the same time, the temperature in the North and South Pole areas is also increasing.
, in 2022, we saw the accelerated melting of Antarctic "Doomsday Glacier". Everyone should not be strange. After all, almost the world is similar to "ants on hot pot". The highest temperature in the past ten years is also common. How fast is
, how fast is the accelerated melting of the Antarctic "Doomsday Glacier"?
According to the expert team of the University of Marine Sciences at the University of South Florida, through the first key area data of the Antarctic Glacier, which was drawn by high -resolution, the Antarctic "Doomsday Glacier" has undergone unusual changes. Its melting Speed and In the past, the fastest glacier melting speed is much faster.
has been in the past 200 years that human melting speed estimates have decreased a lot. New research data shows that it was twice the past.
If you go down at this speed, it will soon be completely melted. This is not a good thing. Because Antarctic "Doomsday Glacier" is very large. After all melting, it will lead to a violent rise in sea level, which will cause threats to the coastline. People living in the offshore region may face a state of unable to survive because of the rise in sea level.
is at the same time. After the sea level rises, the marine storm may also accelerate the threat it brings. Therefore, this requires humans to be vigilant. However, it is clear that vigilance is also useless, because global warming is still continuously occurring.
If the Antarctic "Doomsday Glacier" melted, where will China be flooded?
Antarctic "Doomsday Glacier" is the widest glacier on the planet with a span of about 120 kilometers, so it is very large. In recent years, with the continuous development of global warming, the rise of ocean temperatures, and the improvement of warm air and other issues have led to repeated transformations of glaciers.
has melted 600 billion tons of ice from the 1980s to 2017, and the annual melting is about 50 billion tons of ice, which has led to an annual increase of about 4%per year. In the new investigation report in 2022, we have seen its risks further.
So, according to scientist Graham, the melting speed of the Antarctic "Doomsday Glacier" also over 2.1 kilometers of "distance". Of course, many people see that the "distance" of more than 2.1 kilometers a year has retracted. This is not a big deal, and it is impossible to threaten. In fact, there is another misunderstanding here. Here is a "distance" shrinking.
You must know that its thickness is clear -this glacier cannot be underestimated. According to the data released by Daily Mail , it is 4000 meters thick, so it is considered the key to predict the rising global sea level rising.
is the reason. And if the "Doomsday Glacier" melted in Antarctica, the sea levels caused by it rose -according to the data, it was up to 10 feet (about 3 meters), that is, all the "doomsday glaciers" melted. Essence What will the impact of China will have 3 meters?
First we can make it clear, that is, China's sea plane has indeed risen. According to the sea level data released in 2022:
was from 1980 ~ 2021. China's coastal sea level rising rate was 3.4 mm/year, which was higher than the global average level at the same time. Among them, in 2021, the coastal plane of China was 84 mm higher than the year, and it was the highest since 1980. In the past ten years, the coastal sea level of China has been in the high level in nearly forty years. The main cause of
and China's sea level rising are included -caused by factors such as seawater temperature and expansion of seawater caused by warming wait.
is in different areas in my country, and there are some changes in the height of the sea level.
For example: In 2021, the regional characteristics of the coastal sea plane change in China are obvious. Compared with the perennial year, Bohai HT, Yellow Sea, East China Sea and South China Sea Planes are 118 mm, 88 mm, 80 mm, and 50 mm. Essence Therefore, there are certain changes in different areas. But the overall rises, this is not controversial.
So, if the Antarctic "Doomsday Glacier" melts, it will inevitably have the impact on my country's sea level. Antarctic "Doomsday Glacier" has melted, and the sea level rises by 3 meters. Where is my country the worst, the most drowned? Although
has only increased by 3 meters, for my country, there are still many areas of influence. Judging from the simulation data rising by the sea level, if it rises for 3 meters, it will affect the South China and East China and other places in my country.
, South China is mainly Pearl River Delta region, such as: Shenzhen, Zhuhai, Guangzhou and other places. Of course, in addition, there are also flooding belts in Leizhou Peninsula . However, this area is not the most serious in my country.
's most serious flooding area is still in the northern region. After the rise of 3 meters, Hebei, Tianjin, Liaoning, Shandong and other places also have submerged areas, but the area is not large. The biggest flooding area is Jiangsu.
large areas in Jiangsu are under the flooded areas. Among them, the eastern area of Jiangsu is basically completely overwhelmed. Therefore, this is the worst area on the plane of China. This is a risk.
summarizes
Overall, the threat of rising sea levels does exist. However, there is also room for changing the height of the sea level, and there are certain differentiation in different areas.
is discussed here to discuss my country's sea level rise, which is also based on direct data. For everyone, please refer to it.
and the whole thing tells us that the change in global warming is urgent. Human beings should plan for the climate of the earth, otherwise the threat of climate will only increase step by step, not decrease.
