Why is the weather in Sichuan so strange this year?

Since July, there has been continuous high temperature weather in many parts of the country, and the temperature in many areas has reached above 40℃. However, it is inevitable that snow will appear in Dagu Glacier in Sichuan on such a hot day. Some time ago, there was snowfall in Gansu, and even the temporary tents built by herdsmen collapsed. I have to say that the weather this year is really abnormal.

In fact, not only China, but also many countries and regions around the world have experienced rare weather changes. Even in very cool countries and regions, the temperature has reached above 40℃, such as Britain and France. The highest temperature of 40.2℃ appears in July. High temperature not only affects people's travel, but also is prone to natural disasters such as fires. The drought caused by high temperature weather has caused a devastating blow to crops and seriously affected people's lives.

The reason why the weather is so abnormal this year is not only global warming, but also the influence of subtropical high. I believe many friends should know that global warming is mainly due to the release of too many greenhouse gases into the air. In the early years, scientists came to this conclusion when studying polar glaciers, but no one paid attention. Now it seems that the rare high temperature weather in the world may be the influence of global warming.

In addition, once the subtropical high controls a certain area for a long time, it will also make a certain area suffer from drought and high temperature for a long time. No matter what causes the abnormal weather, the fundamental reason is that human beings do not pay attention to the environment. Since mankind entered the industrial age, despite the remarkable economic and social development, greenhouse gases emitted by some factories have undoubtedly caused serious damage to the environment. The change of the environment is closely related to everyone's life, so now, everyone must establish the consciousness of protecting the environment.
