As the highest peak in the world, Mount Everest must be known to anyone who has read books! In real life, many people want to climb the peak of Mount Everest to see it, but this is just a thought. It is very difficult for ordinary people to climb the mountain.

However, in 2020, a professional climber in the UK discovered a strange phenomenon at an altitude of 6159 meters. At such a high altitude, grass grows in some places. It feels strange to think about it, how is this possible?

However, this is indeed the case. When he announced the news, it immediately caused a heated discussion, and even caused panic among experts and scholars. Because this is not good news, and if it continues to develop, the world may suffer.

Introduction to Mount Everest

Mount Everest is the highest peak in the world with an overall elevation of 8,848 meters. It is located on the border between China and Nepal and is the main peak of the Himalayas. Due to its highly challenging nature, many mountaineering enthusiasts want to challenge every year.

The shape of Mount Everest is like a super-large pyramid. Its terrain is high in the south and low in the north. The terrain is very complex and steep. It is surrounded by cliffs and cliffs. In addition to the cold climate, the living environment there is very harsh.

The lowest temperature on the summit of Mount Everest is minus 34°C all year round. In some places on the mountain, snow does not melt all year round, and glaciers, ice slopes, and ice tower forests can be seen everywhere. The air at the top of the peak is thin, and the oxygen content of the air is only one-fourth of that in the eastern plains.

Sometimes there will be strong winds of level 12, the wind blowing snow, splashing and dancing, filling the sky. Mount Everest has great scientific research value and has been noticed by people for a long time. In 1960, Chinese mountaineers and scientists defied all odds and overcame many difficulties to climb the summit of Mount Everest from the north slope for the first time, creating an unprecedented miracle in the history of world mountaineering.

In fact, the Himalayas where Mount Everest is located was originally an ocean. After a long geological age, a large amount of gravel and sediment was washed from the land and accumulated in the Himalayas, forming a marine sedimentary rock layer with a thickness of more than 30,000 meters. .

After intense orogeny, the Himalayas were squeezed and uplifted violently. According to estimates, the average increase is about 20-30 meters per 10,000 years. Up to now, the Himalayas are still rising.

Why is there grass growing on the mountainside of Mount Everest?

In our imagination, Mount Everest should be covered with snow all year round, with only endless glaciers and snow-capped mountains. However, this is not the case, because of climate and altitude factors, there are still green plants and shrubs below 5,000 meters above sea level.

2,000 meters above sea level is the evergreen broad-leaved forest belt, 3,000 meters above sea level is the coniferous broad-leaved mixed forest belt, 4,000 meters above sea level is the coniferous forest belt, and 5,000 meters above sea level is the alpine shrub belt and alpine meadow belt. No green plants to be seen.

We know that in areas above 5,000 meters above sea level, for every 100 meters, the temperature there will drop by 0.6 degrees Celsius, so the higher the altitude, the lower the temperature.

Normally, some vegetation needs suitable temperature and fertile soil to grow. Seeds cannot germinate in the harsh climate and oxygen-poor conditions like Mount Everest, but it is really worrying that green plants are appearing at an altitude of 6 kilometers.

What does it mean when greenery occurs on a mountain at an altitude of 6000 meters?

As early as 1975, humans launched a meteorological satellite to Mount Everest and began to survey and explore it. Beginning in 1993, images from satellites showed that there were green plants growing on Mount Everest.

This discovery is a very bad situation for human beings. If the range of green plants becomes wider and wider, it will bring huge trouble to human beings. Therefore, attention must be paid to prevent it from happening.

The main reason for the appearance of green plants on Mount Everest is the warming climate. Although this is a long process, once it happens, it means that things have reached a very serious level.

Because in the process is likely to bring extreme weather, must rain, rain and snow or even earthquakes. So what does global warming mean for humans?

1. Melting glaciers bring endless disasters

It is an indisputable fact that climate warming has caused glaciers to melt. Now there are green plants at the peak of 6 kilometers above sea level, which happens to be the most powerful proof. Don't think that melting glaciers has little to do with us, but actually endangers everyone on the planet.

Because melting glaciers will bring endless floods, this kind of disaster is different from the past. After the floods, there will be droughts. For human beings, it is undoubtedly the end of the world, and it is scary to think about it.

And there are 1.4 billion people living around the Himalayas, and they will be the first victims if the glaciers melt on a large scale.

2. Sea level rise

Sea level rise is a global sea level rise phenomenon caused by global warming, melting of polar glaciers, and thermal expansion of upper seawater. Research shows that the global sea level has risen by 10 to 20 centimeters in the past 100 years, and the rise will accelerate in the future.

However, the actual sea level change in a certain area of ​​the world is also affected by the vertical movement of the local land—slow crustal rise and fall and local land subsidence. The sum of the global sea level rise plus the local land rise and fall is the relative sea level change in that area. .

Sea-level rise will also increase ocean dynamics, submerge low beaches, and aggravate coastal erosion. It aggravates the degree of seawater intrusion and soil salinization; causes seawater backflow and affects water quality. Submerged low-lying coastal cities will lead to climate change, severe marine cyclones such as typhoons and hurricanes will increase significantly, and coastal land areas will gradually shrink.
