Nearly 1 trillion grams of smoke particles enter the stratosphere!
On July 20 19, a fire began to spread in Australia. Of course, in the past years, especially after the greenhouse effect was discovered by human beings, there was actually a forest fire season in Australia every year, but the fire in 20 19 was stronger and lasted longer.
Of course, from the root, it is still related to the destruction of the earth's climate and environment by human activities. Under the dual effects of high temperature and dry weather, mountain fires in Australia will naturally become more serious.
According to the statistics at the end of July last year, the fire has caused serious damage to the local climate and environment, and as many as 3 billion wild animals were killed in the fire alone.
Now, it has been nearly a year since the fire. Many people think that perhaps with the baptism of time, the impact of this fire on the earth has gradually disappeared, but in fact it is not. Until today, the climate and environment of the earth have become more severe because of this fire.
A group of scientists from Jinan University, China, have been studying the impact of Australian fire on the earth's climate. According to the data, about 1 trillion grams of smoke particles were sent into the stratosphere in this fire. What concept? It is not only the largest eruption of smoke particles recorded since the era of human satellite, but also the amount of smoke particles released by this fire in Australia is comparable to that of super volcanic eruption, even more serious than the consequences of giant volcanic eruption.
Horribly, these smoke particles entering the stratosphere still affect the climate environment of the earth in the stratosphere today. Because it contains a lot of organic carbon, naturally, it will also lead to more greenhouse gases on the earth, and at the same time, the greenhouse effect on the earth will be more serious.
The Australian fire raised the stratospheric temperature by 2 degrees Celsius.
A large number of data show that although this rare fire in Australia ended last year, the stratosphere has been warming since last year because smoke particles still stay in the stratosphere. At present, the temperature of the whole stratosphere has risen by about 2 degrees Celsius.
And it may continue to heat up in the future, because all kinds of organic carbon in smoke particles will continue to produce thermal effects in the stratosphere and eventually feed back to human beings.
At the same time, the researchers also found that the reason why the ozone hole in the middle and high latitudes of the southern hemisphere suddenly became larger since last year was actually related to the fire in Australia. Although this damage is temporary, the impact of the Australian fire on the earth's climate and environment will gradually decrease in the future, and it may also decrease again.
However, what worries scientists is that with the increasing global warming, it is likely to lead to an irreversible situation.
The end of mountain fires in Australia may be the beginning of another tragedy.
Although the local climate and ecological environment are gradually recovering after the fire in Australia, in the eyes of some researchers, this may be the beginning of another tragedy, because eucalyptus has gradually become one of the main plants in Australia, which will also lead to the next mountain fire, which may be more serious than before.
For many researchers, eucalyptus is also called "immoral tree". Why are they immoral? Because they are essentially a very successful breed, they are also very "cunning".
As we all know, koalas eat eucalyptus leaves, and they often look silly. This is actually because koalas are poisoned after eating eucalyptus leaves, because eucalyptus leaves contain toxins.
In addition, unlike other plants that are afraid of fire, eucalyptus is a kind of plant that is not afraid of fire. After the fire, eucalyptus will have a better living environment. At the same time, due to the rapid recovery of eucalyptus, the original soil was occupied by eucalyptus before other plants recovered.
What is even more frightening is that eucalyptus is a plant rich in oil. Therefore, if eucalyptus becomes the most abundant plant in the place where the fire has burned, it will not only unbalance the local ecological environment, but also "add fuel to the fire" at the beginning of the next fire, making the situation more serious.
Therefore, many researchers will think that although the Australian fire has passed for a long time, it is probably the beginning of tragedy for human beings. what do you think?
