Extreme weather occurs frequently all over the world. Does this have anything to do with human activities?

With the continuous development of human industrialization, due to the extensive establishment and use of various enterprises and vehicles, a large number of greenhouse gases are emitted, and the problem of greenhouse effect is becoming more and more serious. According to the IPCC report, the problem of greenhouse effect is becoming more and more serious due to human behavior. Even now, global warming is irreversible, and global climate change has become more abnormal.

The problem of global warming is of great concern to all countries in the world, but even if emissions are controlled, the temperature of the earth will still rise to 10 years later. Greenhouse gases such as carbon dioxide and methane are the main causes of global temperature rise, so countries all over the world must control greenhouse gas emissions and protect and restore the global environment. In addition, the purification and removal of carbon dioxide is the result of current scientific and technological development, so IPCC hopes to be applied in all countries in the future.

Most countries in the world voted in favor of the IPCC report and analysis, but now the greenhouse effect is still serious, and human activities have a great impact on it, so controlling human behavior seems to be the key. At first, scientists thought that global warming was related to human activities in 1750. With the development of human beings, the emission of carbon dioxide is increasing. Even in the past two million years, there was no such high carbon dioxide content.

According to the data collected by scientists in recent years, the speed of global warming has gradually accelerated in recent years. For example, the warming situation in the past 50 years has exceeded that in any previous 50 years. Nowadays, global warming has become a major problem affecting the earth's environment, such as melting glaciers and frequent high temperature weather. Even nine of the only 15 climate critical points in the world have exceeded the limit, so the seriousness of global warming is beyond our imagination.

Climate critical point is the "wind vane" of the earth's climate. No matter which climate critical point is broken, it will bring disaster to the earth's environment. Some will lead to the melting of glaciers in the polar regions and high latitudes, or the sudden change of ocean currents will lead to local climate change. It can be said that the critical point of climate has as great an impact on the earth as war.

Although the temperature rise of 1.5℃ in the next decade is acceptable, this data seems to be approaching the critical point of climate. If the critical point of climate is broken, glacier melting and sea level rise will occur rapidly. Now, because of the continuous rise in temperature, the sea level has risen significantly compared with before. Many countries in the world are low-lying, and rising sea level will inevitably lead to some countries being submerged.

The probability of extreme weather events has increased. In addition to sea level rise, extreme weather has become more intense in recent years, such as heavy rainfall in Henan, heavy snowfall in South Africa and high temperature of 70℃ in Kuwait. In the view of climatologists, the frequent occurrence of extreme weather is bound to be related to the intensification of the greenhouse effect, which is a "chain" risk. If extreme weather always exists in people's lives, then the normal life of human beings will be disrupted and society will be chaotic.

With regard to global warming, the World Organization has jointly formulated relevant regulations to control the rising trend of temperature. But according to the current trend, it is really difficult to control the temperature rise of 1.5℃. However, the greenhouse effect is irreversible, and all we can do is to slow down the seriousness of the problem. The development of human beings will continuously produce greenhouse gases, but the birth of advanced technology will definitely change the climate pattern. Besides, each of us should participate in and contribute our share.
