The main goal of the Paris Agreement is to control the global average temperature rise within 2 degrees Celsius in this century.

65438+February 65438+February 2020 is the fifth anniversary of the Paris Climate Agreement, and its main goal is to control the global average temperature rise within 2 degrees Celsius in this century. The Climate Action Tracking Organization, which is composed of experts in climate change research from many countries, issued a report saying that at present, it seems that by the end of this century, human beings are indeed expected to approach or achieve the core goals set by the Paris Climate Agreement through actions.

Britain, the first major economy in the world to pass a net zero carbon emission bill, announced that by 2030, its carbon emissions will be reduced by 68% compared with 1990, which is a significant increase from the previous commitment of 53%.

Impact of global warming

Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also affect human health and even threaten human survival.

On the other hand, due to the greenhouse gas emissions from the land, the temperature in the mainland rises, and the temperature difference with the ocean becomes smaller, which leads to the slow air flow and the smog can not be dispersed in a short time, which leads to the increase of smog weather in many cities. Measures such as car restrictions and production suspension have only short-term and local effects, and cannot fundamentally change climate warming and smog pollution.
