Why is the global weather so cold recently?

Recently, extreme low temperature and severe cold swept across the northern hemisphere. It is reported that the severe cold has been raging in Europe for more than ten days, and hundreds of villages have lost contact with the outside world because of heavy snow blocking traffic. The severe cold has killed more than 400 people in Europe. In some countries in Eastern Europe, such as Poland and Ukraine, more than 200 people have died. According to the statistics of Russian authorities, 65,438 people in the country have frozen to death. In addition, in Serbia and other Balkan countries, there are still more than 70,000 people who have lost contact with the outside world. In Xinjiang, Tibet, Inner Mongolia and other regions of China, the continuous severe snowstorm blocked roads and affected the lives of farmers and herdsmen.

In addition to extreme low temperature and severe cold, all kinds of abnormal weather are also "wandering" around the world. From 65438+1October 3 to 1 1 day this year, the southeast of Brazil was hit by heavy rain, which caused floods and killed at least 33 people. 65438105, a mudslide occurred in the southern Philippines, killing at least 25 people, and 150 was missing. 65438+ 10 13, a snowstorm hit the midwest and northeast of the United States, killing three people and canceling hundreds of flights; 65438+1October 18 to 2 1, the northwest of the United States was hit by a snowstorm, which caused at least 12 households to lose power and cancelled more than 700 flights in Chicago. 65438+1On October 24th, a rainstorm hit central Alabama, killing at least two people and injuring more than 100. 65438+1On October 25th, a landslide occurred in Papua New Guinea, killing 40 people and leaving 20 missing. 65438+1On October 26th, many places in Indonesia were hit by storms, resulting in 7 deaths and 5/kloc-0 injuries. ...

The frequent "patronage" of extreme weather has once again sounded the alarm of environmental deterioration.

Although the cold weather in the northern hemisphere triggered a debate about the "Little Ice Age", most scientists believe that the trend of climate warming has not changed. Many meteorologists, such as Wang Qiyi, senior engineer of National Climate Center of China Meteorological Bureau, believe that global warming is the deep-seated reason for this extremely cold weather.

There is no doubt that environmental pollution and carbon emissions are important drivers of global warming. "Extreme weather reminds us to carefully consider the relationship between man and nature and what impact human activities will have on nature." Qiao Xinsheng, a professor at Zhongnan University of Economics and Law, said in an interview with the Legal Daily that human beings should strengthen their awareness of environmental protection, start with carbon emissions and environmental protection in public spaces, and reduce the damage to the environment, thus reducing the factors that induce catastrophic climate.
