World weather news

In recent decades, the earth's climate has been constantly changing, the most obvious performance is that winter is getting warmer and warmer. This is due to the imbalance of carbon cycle in the ecosystem. A large amount of carbon in the stratum is converted into carbon dioxide and discharged into the atmosphere, which leads to the intensification of greenhouse effect and the increase of global average temperature, which in turn leads to the melting of polar glaciers and the rise of global sea level, which directly threatens the living space of human beings.

Some time ago, the World Meteorological Organization, a meteorological agency under the United Nations, confirmed the record of the highest temperature in the Arctic. In the summer of 2020, the organization monitored a high temperature of 38 degrees in the Russian town of Yansk (Vilho) in the Arctic Circle, and the highest temperature in Antarctica was 18.3.

Affected by the inclination of the earth's rotation, the light and heat received by the two poles of the earth are limited, and it is extremely cold all the year round. Only in summer will the temperature above 0 briefly appear. However, the temperature of 38℃ far exceeds the average summer temperature monitored in the Arctic Circle in the past, and even exceeds the temperature in most temperate regions.

This is extremely bad news for the earth. The increase of polar average temperature will not only lead to the melting of glaciers and the rise of sea level, but also be accompanied by severe climate changes such as typhoon, extreme high temperature and heavy precipitation. The World Meteorological Organization has confirmed that extreme weather phenomena around the world in recent years are closely related to the global average temperature rise.

According to the prediction of the World Meteorological Organization, if the average temperature of the earth continues to rise, the earth's climate may return to the Cretaceous period 90 million years ago. During this period, the earth's climate was unusually warm, and the sea surface temperature in tropical areas was as high as 42, much higher than the current 17. If this day comes, the first thing that human beings have to face is the ever-invading sea water, and the few land areas are getting smaller and smaller, which constantly squeezes the living space of human beings.

Aware of the great threat that global warming may bring to mankind, the United Nations launched emission reduction actions to curb global warming many years ago. However, considering the needs of economic development, this plan has not been strictly implemented.

Even if it is strictly implemented according to the plan, the ideal state can only control the global average temperature rise within 1.5 before 2050, and it is irreversible. The earth's climate is a very complicated system. What human beings can do at present is to slow down this process as much as possible. Sooner or later, mankind will face the consequences of rising global average temperature.
