According to meteorological experts, there are 300-400 extreme weather events on Earth every year, and this number is rising year by year.
As temperatures rise, so does the frequency of extreme weather events, with snowfall, freezing and other extreme weather occurring around the world, affecting more than 500 million people.
In fact, many people have felt this change, from childhood to adulthood, they have heard of the time when their ancestors said that "the four seasons are distinct", and now many places no longer have an obvious sense of the four seasons.
What's more, if you ask about summer, there are many people who compare the past summer with the current summer, and most of them say that summer is not only hot, but also getting longer.
Extreme weather occurs frequently, which will have a great impact on people's lives.
But in the distant future, as the global climate continues to warm, humanity will face three more serious disasters: high temperatures, rising sea levels, and the threat of artificial intelligence.
1. Extreme weather is frequent.
According to the statistics of the meteorological department, in 2010, a total of 780 meteorological disaster events occurred worldwide.
In 2019, that number directly doubled to 1,670 times.
Among them, in addition to meteorological disasters that are directly related to global warming, there are also some abnormal situations.
It is inevitable that global warming will lead to an increase in temperatures around the world.
This is also the fundamental reason why the rate of global warming has been increasing since the Industrial Revolution.
Human beings are constantly developing, and science and technology are constantly advancing, but these advances do not seem to have brought a better living environment for human beings, but have brought greater damage to the living environment.
Not only that, with the continuous development of international trade, the number of multinational corporations in the world is also skyrocketing, and these multinational corporations, in order to obtain more benefits, often carry out worse environmental damage in countries without environmental awareness, which is also one of the causes of global warming.
Meteorological experts have also conducted surveys on the frequent occurrence of extreme weather, and they believe that the frequency of extreme weather is also intensified while human resources are constantly developing resources and making scientific and technological progress.
Among them, the main reason is the exploitation and use of fossil energy by human beings.
The exploitation and use of fossil energy will lead to the release of a large amount of carbon dioxide gas into the atmosphere, forming a layer of greenhouse gases such as carbon dioxide in the atmosphere, which will greatly increase the temperature of the atmosphere, resulting in global warming.
This warming will lead to a continuous strengthening of the global water cycle, resulting in an environment with a large increase in rainfall, which is why extreme weather events such as heavy rainfall and floods will occur around the world.
On the other hand, global warming will also lead to an increase in the water vapor content in the atmosphere in the global environment, and the water vapor in the atmosphere is originally a greenhouse gas, and its effect is much stronger than that of carbon dioxide and other greenhouse gases.
At the same time, global warming will also lead to an acceleration of the melting rate of ice and snow in the global environment, which will lead to rising sea levels and shrinking land on the earth, which is why extreme weather events such as huge floods have occurred around the world in recent years.
2. Three major disasters.
Global warming will trigger three major catastrophes: high temperatures, rising sea levels, and the threat of artificial intelligence.
First of all, the most direct global warming is the continuous increase in the temperature of the earth, and many places have not seen high temperature weather for decades, which is easy to cause the spread of many infectious diseases, and at the same time, it is also very unfavorable for the growth of plants.
Many crops, when encountering high temperatures, will die in a large area, resulting in a continuous reduction of food resources on the earth, which means that there will be a large-scale famine on the earth, which will be a very big disaster for human beings on a global scale.
Globally, sea level rise is also becoming more severe, mainly due to the frequent occurrence of extreme weather events caused by global warming, and the retreat of large amounts of glaciers, which has led to the rise of ocean areas around the world.
According to the predictions of meteorological experts, in the next 100 years, the water level in the seas of the planet will rise to about 2 meters, which will be a terrible disaster for some countries on the planet.
Among them, countries such as Maldives and Japan are very low-lying countries, and once the sea level rises, these countries may disappear from the earth, which will be an unimaginable disaster for these countries.
Globally, the development of artificial intelligence is also becoming more and more rapid, and this development has also caused controversy around the world.
Many people are worried that with the continuous development of artificial intelligence, the intelligence of machines may surpass that of humans, resulting in machines replacing humans in future development, which also raises moral and ethical issues in artificial intelligence.
Once the intelligence of machines surpasses that of humans, it will mean that humans will be exposed to unknown risks.
So far, although the development of artificial intelligence has been very rapid, in many ways, the intelligence of machines is still far inferior to that of humans.
However, as time goes on, machine intelligence may continue to evolve and eventually surpass humans, bringing unknown risks, and humanity will face even greater disasters.
3. The threat of war.
In the future, humanity will also face the threat of war.
Although in times of peace, relatively speaking, wars have been decreasing around the world, this does not mean that there is no threat of war on a global scale.
In times of peace, countries around the world are constantly developing new technologies, one of the most important of which is nuclear energy technology.
Nuclear energy technology, once in the wrong hands, will cause irreversible damage to the ecological environment on a global scale, and this will lead to a global war.
Therefore, in the future, humanity must be vigilant about whether this technology will fall into the hands of lawbreakers, whether intentionally or unintentionally, in peacetime, leading to the demise of mankind.
In times of peace, people should pay more attention to the protection of the environment and the future development of mankind, which will foster a peaceful environment on a global scale, but it is also necessary to be vigilant that someone will break this environment, which will lead to a global war.
IV. Conclusion
Humanity will face many challenges in the future, the most important of which is the global challenge of climate change.
While human beings are developing, they are also destroying the living environment, and this kind of destruction must arouse people's vigilance and take positive actions.
This requires the cooperation of the international community and the efforts of everyone, starting with every small thing, in order to protect the future of humanity.
