The World Meteorological Organization predicts that there will be record-breaking high temperatures this summer. What is the scientific basis?

Now many friends should have felt that the weather is particularly hot this year, and the World Meteorological Organization is always one beat behind. Only when people feel hot do they tell people that there will be a record-breaking high temperature this year. Now many areas have reached 40 degrees Celsius, and the temperature in Beijing has exceeded 42 degrees at the end of May, which can be said to be very hot.

1. Earth temperature rises 1. 15 degrees.

Since the industrial revolution, the average temperature of the earth has risen by 1. 15 degrees, which is not a small number, but it can be said that it is very terrible, and there is a place in Beijing that has exceeded 42 degrees. At the same time, there are some average temperatures in China, which do not exceed 14~25℃. That is to say, if the temperature rises by 1. 15 degrees, the average temperature in many areas will rise by one degree before the altitude can reach here. So don't underestimate that 1. 15 degrees is extremely terrible.

Second, why is the temperature getting higher and higher?

In fact, this problem is relatively simple, because human beings will release a lot of greenhouse gases during their activities. The main source of these gases is the burning of some fossil fuels, such as coal or oil used by people, and a large number of nitrogen oxides and sulfides are also emitted. Moreover, carbon dioxide can be passed by visible light in solar radiation, which causes the ground to be locked in the atmosphere after absorbing radiation, and it is very strong, as if there is a quilt made of cotton around the earth. /kloc-At the beginning of the 9th century, the global population was about 10 billion. By 2020, the global population has reached 7.7 billion, which led to a large consumption of resources. In addition, the greenhouse effect rate caused by methane gas is many times higher than that caused by carbon dioxide.

3. The whole world is getting warmer. What is the cause of the snowstorm in winter?

In fact, it is because the water vapor content in the atmosphere will increase greatly when the temperature is high. At this time, the temperature of the gas is very high. When it moves to high latitudes, there will be heavy rain or heavy snow, and there will be a temperature difference when the gas rises, which will lead to the appearance of typhoon embryos in the western Pacific, so more and more typhoons will be felt.

4. High temperature forecast report this year

On May 26th, the World Meteorological Organization released a weather report about this summer. The whole world is suffering from the epidemic. In this high temperature, people have to wear masks, not only that, but also protective clothing. It can be said that under the high temperature, people are easily unbearable. But also pay attention to the vulnerable groups such as the elderly and children. When using air conditioning, we should pay more attention to indoor ventilation and adopt simple cooling methods when cooling down.

At the beginning of the summer of 2020, the temperature has already reached a new high, which makes people feel the high temperature this year.
