The desert is flooding and the earth is "cooling down"? Is the winter warning coming? 202 1 Great climate change?

In the vast starry sky, the earth is the only home for human beings, but this home is not a quiet harbor, but an unpredictable place. During the earth's 4.6 billion years, there have been a series of disasters such as volcanic eruptions, catastrophic floods and earthquakes. However, in the past thousands of years, the earth's environment has just stabilized, but with the violent destruction of our living environment by human beings, the earth is slipping into an unknown abyss. In recent years, the downward trend of the earth's temperature has intensified, and there are more and more abnormal climate changes. Even the arid desert was flooded. The earth's environment is facing great challenges.

Researchers say that the earth is now madly absorbing heat. The climate will change like never before. Scientists warn that the earth will get cold in the near future. What will happen to the climate in 202 1 year? Let's take a closer look at the recent climate change.

The first is the flood in the Taklimakan desert. Everyone knows that the main reason why the desert is barren is the extreme lack of water. If there is enough water, the desert can instantly become an oasis, and trees and grass can grow stronger than ordinary land. Many people think that the Taklimakan Desert in central Xinjiang is the driest area in China, with an annual rainfall of only tens of millimeters. There is only so little water and tens of thousands of square kilometers of land, not to mention no people or even animals. All you can see is endless yellow sand. However, in July, 20021year, a record flood suddenly appeared in the Taklimakan desert, which had been dry for a long time. Where do you go to school in the desert? 300 square kilometers of water. The desert turned into a lake, giving birth to a land of geomantic omen. There may be countless tall buildings rising from here in the future. I feel very excited when I think about it.

Unfortunately, Sinopec's northwest oil field was built in Yuqi area of Taklimakan Desert. As a result, the record flood in the desert caused us great losses. Dozens of investigation vehicles and tens of thousands of mining facilities were flooded. Oil workers have to use existing equipment to resist floods in the desert. How to stop the flood in the flat desert? It's not as simple as where there are mountains and water. Discharge the flood into the river. The biggest problem of desert flood is that there is no way to release water. The effective way is to build a water storage dam to prevent flood, and then wait for the water to evaporate at high temperature. There is no other way.

Then, why did the Taklimakan desert encounter a major flood? Let's learn about the topography of the Taklimakan desert first. Tarim basin is like an oval sand basin. Taklimakan Desert is the sand in the desert basin. Tarim basin is surrounded by mountains. For thousands of years, water from the mountains around Taklimakan Desert has been flowing into the desert. Some of them have evaporated. Where did the rest of the water go?

Some people say that the surface of Taklimakan Desert is arid and barren, but underground rivers may be buried in all directions. Of course, this is just a guess and needs to be confirmed. Recently, the Tianshan mountain area was hit by heavy rain for several days, which accelerated the seasonal melting of snow and ice on the mountain and led to seasonal floods. These floods eventually flowed into the Taklimakan desert, forming a lake in the desert. Unlike ordinary soil, sand has no water storage capacity. In addition, the terrain of sand itself is relatively flat, too much water will flood a large area, and there is no place for drainage, so it can only be reduced by evaporation. This is another major cause of flooding in Taklimakan Desert.

In recent years, the change of earth temperature has also become a hot spot of environmental concern. Many scientists say that there will be a sharp cooling phenomenon in the future, and the earth is absorbing heat crazily. 202 1 may be the beginning of temperature change. In today's scientific community, there are two completely different views on the future of global climate change. One is that the earth will become hotter in the future, and the other is that the earth may enter the Little Ice Age in the future. But why do scientists put forward these two different views? Will the future of the earth become hotter, or will it enter the Little Ice Age?

According to the report of the earth's carbon dioxide concentration in May 20021year, we can find that the earth's carbon dioxide concentration has reached the highest level in history again. From this perspective, the future trend of the earth's temperature must be an upward trend. There is some truth in this statement. So, what is the theoretical basis for the earth to enter the Little Ice Age?

An article was published in Geophysical Research Express, from which we can see that the heat absorbed by the earth from the atmosphere is about twice that of 15 years ago, so the earth is madly absorbing heat, which is mainly caused by the climate change of the earth, and the heat absorbed by the earth is also the waste heat that the earth cannot digest. And the energy of the earth is out of balance. Part of the energy is "recycled" by the earth itself, and the part that cannot be recycled can only be lost during the term of office.

The earth entered the Little Ice Age mainly because of the change of sunspot activity. As we all know, the temperature change of the earth depends largely on the sun and is closely related to it. Some scientists say that based on sunspot anomalies, the earth will enter the Little Ice Age. The increasing concentration of carbon dioxide on the earth means that the earth needs to be adjusted, otherwise it will affect the earth's ecology. As greenhouse gas emissions continue, the earth's own "equilibrium point" will contain more heat than normal. Scientists call it a normal imbalance.

At this point, the excess heat is due to too much "global warming" because the earth can't balance it. On the surface, the earth absorbs heat to maintain ecological balance. One day in the future, will more than twice as much heat become the last straw to overwhelm the earth?

Obviously, this is a problem that human beings need to think about today. Over the years, many unusual things have happened on the earth, such as floods, typhoons and tsunamis. However, when all natural disasters occur in the same time dimension, how can we not feel a little worried? After all, we only have one earth. Humans without the earth are like duckweeds without roots.

In the face of the impact of climate change brought by the increase of human activities, we need to vigorously control the emissions of greenhouse gases such as carbon dioxide, do our utmost to achieve the carbon-neutral goal set by the state, and limit the temperature rise to a certain range, so as to achieve the goal of coping with climate change. Fundamentally reduce the impact and harm of future climate change; On the other hand, by the middle of 2 1 century, the global temperature will further rise, and the influence of extreme weather and climate events will further increase. Therefore, we must do a good job in disaster prevention and mitigation as soon as possible. Improve the ability of disaster risk management and adaptation to climate change.

202 1 year may be the beginning of global climate change. Humans seem to be the masters of the earth, but in fact, all the creatures living on the earth are the same. We are all species that can survive on the earth. Everyone knows how to protect the earth, but with the rapid development of science and technology, how should we choose between development and protection?

Ok, that's the end of this issue. I hope you like this little attention. See you next time.
