There are more and more extreme weather on earth. What is the reason?

Extreme weather on the earth has caused great losses to the safety of human life and property, especially in recent years, extreme weather events have become more and more frequent, and the main reasons behind this are global warming and human activities, the movement of the earth and the sun.

1. Global warming leads to more and more extreme weather.

At present, a team of scientists has shown that global climate change is one of the main reasons for the increase in the frequency of extreme weather events, that is, greenhouse gas emissions have led to climate change and global warming. In fact, this is mainly a physical phenomenon. After the temperature rises, the water vapor content in the air will gradually increase, and a necessary condition for rain is that there is enough water in the air. When water vapor rises into the air, it will go through a long period of rainless stage, which will form drought, while the latter will encounter more violent precipitation, thus forming floods. This is also the reason why there have been more droughts and frequent floods in some places in recent years. Even with the increase of moisture in the air, extreme worlds such as rainstorm and blizzard have appeared in some places, and tornadoes, thunderstorms and strong convective weather will form in the air, which will also occur in some areas, causing great losses to the safety of life and property in some areas.

Second, human activities are also factors that lead to frequent extreme weather.

Human activities will have a great impact on the earth. Living on the earth, whether it is normal traffic, industrial manufacturing, heating, intelligence, combustion, will emit carbon dioxide. In addition, trees are cut down, rivers are transformed, and habitats of animals and plants are destroyed. It will also cause great changes in the environment. It is precisely because of these factors that the earth's ecological environment has changed and extreme weather is prone to occur.

Third, the movement of the earth and the sun.

Some scientists have shown that the periodic change of the earth's orbit directly affects the earth's reception of solar radiation, and the increase or decrease of solar radiation will lead to the change of the earth's climate. Moreover, during solar activity, radiation will also increase, leading to global warming. It is precisely because of these two factors that extreme weather on the earth will happen.

To sum up, there are more and more extreme weather on the earth, and the challenges facing mankind are getting higher and higher, so we should pay attention to protecting the environment and cherishing the earth in our daily life.
