The temperature in Beijing has exceeded the historical extreme value for the same period. Why is there such an extreme performance?

After the Spring Festival, the temperature in Beijing begins to heat up. Although it was still chilly in the morning of the 20th, the temperature continued to rise in the afternoon, breaking the historical extreme value for the same period. The Beijing Meteorological Department reported on the 20th that the weather in Beijing continues to get warmer. The temperature at the Southern Suburb Observatory reached 20°C at 14:45, exceeding the historical extreme value for the same period in February, reaching 20.8°C at 15:50. Warmth and a hint of spring. Many people took off their thick cotton-padded clothes and put on unlined clothes to enjoy the warmth of the streets. This year’s Spring Festival made me doubt the return of spring in Beijing. I really like spring in Beijing and just wear two pieces of clothing outside.

Spring will begin in Beijing on March 15, 2020, half a month earlier than usual. When the continuous five-day moving average temperature series is greater than or equal to 10°C, the first date in the corresponding temperature series is regarded as the start date of spring. Spring has not yet arrived, and the cold air is about to return. With the entanglement of warm and cold air, the temperature in Beijing will be as volatile as a roller coaster. The Beijing Meteorological Department reminded that starting from the 21st, the temperature in Beijing will gradually drop. The maximum temperature will drop to 6℃ from the 23rd to the 24th, which is more than 10℃ lower than the current level. The temperature changes greatly, so people should pay attention to adjust their clothes in time to avoid catching cold.

The temperature is rising faster and faster, the industry is becoming more and more developed, and more and more trees are being cut down, causing the air quality to fail to meet standards. In order to make the air quality more and more up to standard, people began to plant trees on a large scale. To reduce carbon dioxide in the air, many people encourage others to plant trees. We all know that plants absorb carbon dioxide and reduce air pollution index. In addition, more natural energy is used by scientists to generate artificial electricity, saving a lot of materials. Especially now that the application of wind energy is becoming more and more widespread, there are some wind power machines that use electricity and wind power in many fields in my hometown. These wind power generation equipment bring many benefits to people, such as people do not have to worry about a series of problems such as power outages.

I believe we all know that there are many kinds of trees in the forest. Especially in some tropical rainforests, the trees there are particularly impressive, but as people enter the tropical rainforest more and more, many trees are now destroyed. People have cut down the trees in the forests so much that some forests have turned into deserts. In order to prevent the forest from becoming a desert, people began to plant some plants that are easy to support and have strong vitality, such as cacti, poplars, etc. We need to understand that it is very dangerous for humans to destroy nature. If a forest is destroyed, it may take hundreds of years to recover, and it may never recover. Forests are very good to people. Too many plants can allow people to breathe a better environment and resist some natural disasters such as mudslides.
