Who is the high temperature "culprit"?Natural variables randomly affect the indirect impact of human activities

This summer, waves of high -temperature heat wave swept the world. Many European countries have continued to issue high -temperature warnings; high temperatures have continued to increase since July in many places in my country. A few days ago, Chen Ruidan, an associate professor at the School of Atmospheric Sciences of Sun Yat -sen University, said in an interview that the causes of high temperature heat waves include two parts: natural changes and human activities.

From the perspective of natural changes, the direct reason for the high temperature is the control of the high -pressure system, which is like buckling a hot pot lid over humans, locking the heat compression in the influence area. The high -voltage system that affects South China is mainly related to the Northwest Pacific subtropical high -pressure, and the high -voltage system that affects the mid -latitude region (such as the United Kingdom) is mainly related to the fluctuation of the western wind belt. These high -pressure systems have been very strong since this summer, resulting in a large -scale continuous high temperature heat waves. Essence

In addition, human activities are another important factor that causes high temperature heat waves. Carbon dioxide emitted by human activity is an important greenhouse gas. A large amount of carbon dioxide is like covering a quilt on the earth, and the sun calories that are irradiated to the surface are more locked on the near ground layer. Compared with the randomness of natural changes, the impact of human activities is relatively certain. Related studies have pointed out that human activities have greatly increased the probability of breaking the high -temperature heat wave incident, and the high -temperature heat wave incident that is currently experiencing is likely to become ordinary in the future.

In the face of increasingly high -temperature heat waves, it has been urgent to take effective response measures. Among them, very important and effective measures are to reduce carbon dioxide emissions. While the country's development of new energy, the development of a circular economy, and vigorously increase the degree of greening to increase carbon exchange, individual advocates low -carbon life, such as green travel and reducing waste of resources to emission reduction.
