2020 is coming to an end. We have indeed felt "cold" in the past two days. Experts have also clearly stated that it is really cold. Is the coldest winter in 60 years real? Of course, before discussing this issue, let's take a look at the new data. The World Meteorological Organization pointed out through data that the end of 2020 will mark the end of the warmest decade on record. What is the situation?
means that the climate state in 2020 has reached a new high, so this is not good news for all life on earth. At the same time, 2020 may become one of the three hottest years on record. One, it's even on par with 2016.
Everyone should know that in 2016, the reason why the temperature reached a new high, which exceeded global warming , was the impact of the El Niño phenomenon. Fortunately, La Niña phenomenon , La Niña phenomenon appeared in 2020. It is a signal that caused the earth to cool down, but it still cannot reverse the warming up situation, so this is not good news. Therefore, 2020 is still an unusually hot year, and the global climate is affected by it. According to most simulation data, the La Niña phenomenon is expected to reach its peak in December or January 2021, so at least it is certain Yes, the La Niña phenomenon is still developing, this is the general situation.
At the same time, under the influence of climate change, the natural disasters brought about in 2020 will also have a relatively large impact. A new report issued by the United Nations points out that the global loss caused by weather disasters in 2020 will be as high as 150 billion US dollars, exceeding the figure in 2019. , Reflecting the long-term effects of global warming. Therefore, the increase in extreme events of and is an important problem facing mankind. Among them, Bangladesh suffered one of the worst floods in history in 2020, and more than a quarter of the country was submerged by water. An extreme high temperature of 38 degrees has appeared in the Arctic Circle, and wildfires are also burning, which shows that climate change has become more severe.
So the global warming continues, these problems will become normal, and compared with the end of the 19th century, the average surface temperature of the earth has risen by at least 1.1 degrees, which means that mankind is away from the "Paris Agreement" in a feasible state. The limit of 1.5 degrees is approaching, and it is getting closer, so according to many experts, it is less and less likely to stay below 1.5C. At the same time, under the influence of climate change, unprecedented wildfires will cause large-scale deaths of animals and plants. The likelihood of fatal heat in Europe has increased by nearly 100 times over a century ago. Heat waves and floods that occur once in a century will also be even greater. universal. At the same time, the climate change we are seeing today is also under influence.
Of course, our country’s climate change nowadays, in addition to global warming, the most important thing is the impact of the La Niña phenomenon. After we have read the state of the earth, let’s continue to see what is "really cold" now. The situation, the coldest winter in 60 years is true? In fact, the main factor today is that La Niña and the Arctic sea ice are less important. Let’s talk about the La Niña phenomenon alone, because at the beginning it was said that “this year may be the coldest winter in 60 years”. The phenomenon has the greatest relationship. It is undeniable that the La Niña phenomenon is indeed affecting climate change.
Generally when the La Niña phenomenon develops, my country is prone to active cold air and colder temperatures. Even if it is very cold today, it can only be said to be part of the factor, but this winter will be colder or warmer. Comprehensive research and judgment based on scientific analysis. Now we have no way of judging whether it’s cold or hot, because December this year is the first month of winter. Even if December is colder, it does not mean that January and February 2021 will be colder. So there is no way to determine whether it is hot or cold for the time being. There is no way to say that the coldest winter in 60 years is true this year. Without data, there is no way to compare. This is normal.
So the meteorological analyst of the China Meteorological Administration gave this statement, that is, whether the final result is cold winter or warm winter, or to wait until 2020It can be determined at the end of February of the year, and at the same time whether this winter is the coldest winter in 60 years, data can be given.
