The past Typhoon No. 8 Maria once again made people realize the ruthlessness of nature. It brought storm to coastal areas. After the typhoon, it was a mess and people’s property suffered heavy losses. Fortunately, people moved in time and there were no casualties.
Yesterday, meteorological experts announced that the new typhoons No. 9 and No. 10 are also brewing, and may soon land in China’s coastal areas again. Although the new typhoon will take some time, but Typhoon No. 8 has just passed, people have to face a new challenge: high temperature.
According to the latest news released by the meteorological station, from July 16, most parts of China will have a long period of high temperature weather, which is the most extensive and the strongest high temperature process this year. In the hot sun, people should be prepared for high temperature, otherwise it is easy to get heatstroke in the hot weather.
In recent years, the high-temperature weather has reached a new high every day. Netizens tease that it is now “five minutes to go out and sweat for two hours”. From the 13th, Huanghuai, Jianghuai and Jiangnan areas took the lead in high-temperature baking. From the 14th to the 15th, the high-temperature weather rapidly expanded to Jianghan, Eastern Sichuan Basin, North China and even Southern Northeast China, and the scope of hot sun baking continued to expand.
According to the website of China Meteorological Administration, from 9:00 to 18:00 on the 15th, nearly 50 prefecture level cities across the country were in the process of high temperature warning, and the provincial meteorological departments of Hunan, Hubei, Shandong and other provinces also issued high temperature warning throughout the province. According to the monitoring of the central meteorological station, 35-37 ℃ high temperature weather occurred in Huanghuai, Jianghuai, northern and western parts of Jiangnan, Hubei, Chongqing and Guanzhong of Shaanxi during the daytime on the 15th.
The meteorological department reminds that in high temperature weather, people should try to avoid outdoor activities during high temperature in the afternoon, provide guidance on heatstroke prevention and cooling for the elderly, the weak, the sick and the young, and take necessary protective measures. Outdoor or high temperature workers should take necessary protective measures. In addition, the relevant departments should pay attention to prevent fires caused by excessive power consumption and heavy load of power equipment such as wires and transformers.
Why is the hot weather getting worse in recent years? It is mainly due to the rising global temperature caused by the greenhouse effect, and behind the greenhouse effect is the continuous destruction of human environment. Human society began from the industrial revolution, the rapid rise and rapid development of scientific and technological civilization. In the past 50 years, the development of science and technology is changing with each passing day. It can be said that new technology is born every day. Such rapid development has brought convenience and significant changes to people’s lives, but also caused great pressure on the environment.
The development of science and technology is inseparable from resources and energy. The massive development of resources, the random blowing and felling of trees and so on make the earth lose a lot of green, desertification intensifies, and sandstorms sweep the sky. More importantly, the emission of a large amount of tail gas makes the concentration of carbon dioxide in the atmosphere continue to rise, resulting in the greenhouse effect. The global temperature is also rising under the effect of the greenhouse effect. The global temperature is now 10 degrees higher than that of 50 years ago.
The rising global temperature has not only affected people’s life and career, but also affected the melting of ice and snow in the north and south poles. At present, the bottom of ice in the north and south poles has begun to melt, and the plates have begun to split and move. The continuous melting of ice has caused the rising of global sea level, and more floods.
The continuous high temperature weather also accelerates the convection on the ocean, which is an important reason for the formation of typhoon. Therefore, the higher the temperature is, the easier the typhoon forms. Therefore, in the future, typhoons will be more frequent, and the intensity may continue to reach new heights, and the violence of typhoons will far exceed some other natural disasters.
Scientists are also very worried about global warming and are actively trying to find ways to cool the earth. However, with the current technology of human beings, it is very difficult to cool the world. Some scientists once imagined to build a huge reflector between the earth and the sun to reflect the sunlight back, so that the earth will receive less sunlight and the temperature of the earth will drop Come on.
Although this idea is good, and it can be achieved by human science and technology, this plan can not be completed by one country. It needs all the countries in the world to unite together. It needs too much money, but it is difficult to make all the countries in the world pay for it now. Maybe the earth will be too hot to survive in the future Only in this way can we unite.
However, some scientists believe that the activity of sunspots is weakening by observing the activity of sunspots, which indicates that the earth may usher in a little ice age. If so, it’s good news for the earth. The little ice age is a natural air conditioner, which can effectively cool the earth. With the high temperature of our earth, if the little ice age It’s going to last for decades, and it may bring down the temperature of the earth to decades ago, which is definitely good news.
No matter typhoon No.8 or the coming typhoons No.9 and No.10 are caused by human beings’ destruction of the environment. The continuous high-temperature weather every year is also the destruction of the environment brought about by the development of human science and technology. If we want to reduce the number of typhoons and high-temperature weather, we must protect the environment and protect the environment We believe that the future of the earth will be better.
