Global warming is no stranger to everyone. As the earth continues to warm up, more and more extreme climates appear, and the chain effects caused by the warming are getting stronger and stronger, such as high temperature, drought, severe storms, etc. At the same time, the melting of glaciers in the Arctic and Antarctica is accelerating, causing the sea level to rise. However, the melting of glaciers in mountainous or plateau areas has an "unexpected" effect, that is, the formation of ice lakes. It may even bring floods. Of course there are other effects, we will talk about later.
Now the world is paying attention to one place, that is, " Qinghai-Tibet Plateau". Under the influence of human activities, it can be said that the Qinghai-Tibet Plateau has undergone major changes. This change is a kind of survival crisis for mankind.
The Qinghai-Tibet Plateau is warming faster than expected
According to the "Environmental Research Letters", the temperature rise in the Qinghai-Tibet Plateau has exceeded the global temperature in the past few decades. The rising average level, and since 1960, this change has continued to occur, the main factor is the impact of human activities, of which the greenhouse gas ribs are the most severe. Now that the Qinghai-Tibet Plateau exceeds expectations, scientists predict that the plateau may heat up faster in the future than climate models predict.
simulation data shows that under the medium carbon emission scenario (RCP4.5), the Qinghai-Tibet Plateau is expected to warm in the mid-term (2041-2060) and the end of the 21st century (2081-2100) 2.25°C and 2.99°C), the temperature is 0.24°C and 0.32°C higher than the uncorrected predictions, so it is higher today and may be higher in the future.
So this is really "out of control",The speed has increased and increased. Of course, this change is also in line with the trend of today’s scientific predictions. In the past year, our planet’s warming has continued to occur, and it has also set a new high. Then the Qinghai-Tibet Plateau will inevitably increase. Our planet is a whole. The warming is taking a walk in any corner, so the warming must be synchronized.
The Qinghai-Tibet Plateau is turning green, and ice melting disasters have already occurred
We all know that the Qinghai-Tibet Plateau is the most ice region besides the North Pole and Antarctica. After it melts, it supplies water to dozens of major rivers in Asia, giving life to billions of people downstream. However, as the Qinghai-Tibet Plateau heats up, the formation of ice lakes accelerated by ice melting has also accelerated, leading to landslides, mudslides and glacial lakes erupting. This kind of ice melting disaster has also occurred, and India has already tasted the bitter fruit.
Everyone should remember that the hydropower station under construction in the Indian Uttarakhand State was destroyed by a mudslide. The last reason was that the lake was destroyed by ice accumulation. The huge ice melt water pressure caused the dam to collapse, which led to the complete collapse of the hydropower project under construction, so the catastrophe caused by the melting of glaciers has already occurred.
At the same time, after the melting of ice on the Qinghai-Tibet Plateau, large-scale lands are exposed, which makes the area green. Many people might say that growing vegetation is not a good thing. ? It is true that vegetation greening the earth is a good thing, but ice melting is a bad thing. When the ice melts above the critical point, the Qinghai-Tibet Plateau may indeed turn green in the future, because there are no glaciers, but a greater disaster is behind, because there is no ice. Melted water sources, rivers dry up, and the residents living downstream have no water.So in fact, the bigger disaster is still to come.
According to the "Nature Review: Earth and Environment" magazine, the vegetation has turned green in the past 40 years, and the vegetation in the Qinghai-Tibet Plateau and the northern high latitudes has become greener The most critical role, and the greening of vegetation in different regions is not the same, and after the emergence of vegetation, it also intensifies the global water cycle and forms climate "fluctuations", so it will again trigger the pattern of rainfall. This is the Qinghai-Tibet Plateau change zone. Influence.
Hasn't a bigger disaster come yet?
In addition to these catastrophic problems, there are more serious problems, and even greater disasters may indeed have not come. Global climate warming may cause the emergence of an unknown virus in the Qinghai-Tibet Plateau. Scientists from Ohio, on the Qinghai-Tibet Plateau In the ice nucleus samples, evidence of the existence of ancient viruses was found. Among them, there are 28 new viruses, so this is very dangerous. This is also very stressful for scientists to avoid that global warming is causing glaciers around the world to shrink , And these sealed viruses may be released.
At the same time, according to scientists, if the earth continues to heat up, it is likely to release microorganisms and viruses that have been frozen for tens of thousands or even hundreds of thousands of years. And there are many unknown factors, so once it is released, it may affect human beings in the next second. This is not "warranty", but a tangible explanation of real data. Of course, the release of ancient creatures is not the first time it has been explained, but it is a normal topic in the scientific community.
So overall,The continuous warming of the earth is not only caused by the emergence of problems such as the Qinghai-Tibet Plateau. There may also be greater disasters that have not come. The virus is already very powerful in the world. There are more unknown viruses and microorganisms, and the impact on mankind will inevitably be. It's even bigger, so humans should take good care of the environment, otherwise they may endanger their own survival in the next second.
