French media: What causes floods and heat waves in China this summer?

Agence France -Presse reported on June 25 that the original topic: What caused the flood and heat waves that have created a record in China? This month, the record in some regions of southern China caused more than 500,000 emergency risk aversion. At the same time, the turbulent waves transformed the roads in some parts of China. Relevant departments issued extreme weather warnings in many places, and experts warned that these phenomena further proved the impact of climate change.

How serious is the flood? In China, the floods are common in summer, especially the low -lying Pearl River Delta regions. However, the National Meteorological Center of China predicts that the flood is relatively severe and "more extreme" than in previous years. The water conservancy department stated that the water level in Guangdong this week "exceeds historical records", and the precipitation in some areas adjacent to Fujian and Guangxi has also reached a record high. In Guangdong, it is estimated that the economic losses caused by floods exceeded $ 250 million.

How is the heat wave? As the local temperature is as high as 40 ° C, 7 provinces in northern and central China have warned residents to minimize their out. The media played the picture of the cement road in Henan under extreme heat waves. China ’s second -population province in Shandong, one day, has a power load of more than 93 million kilowatts one day, refreshing the 90 million kilowatts recorded in 2020.

How big is economic loss? Extreme weather will lose 1%to 3%GDP each year. Studies by Swiss Reinsurance Corporation showed that the losses in China's floods last year were as high as US $ 25 billion -the second largest losses after Europe. The Chinese government recently issued a warning that floods and heat waves will affect the production of food, vegetables and pork and push high inflation.

Why is this phenomenon? The Chinese Meteorological Department said that extreme weather incidents in this country have become more frequent, serious, and universal. The global warming and "La Nina" phenomenon leads to abnormal high temperature and extreme rainfall in China. As the earth's atmosphere becomes warmer, the more water that is carried has exacerbated the rain.

How is China dealing with it? China has created a huge dam and "sponge city" network to curb the damage of flood during the flood season. But the University of Pennsylvania, a researcher at the University of Pennsylvania, said: "The most destructive flood recently occurred in areas where risks have always been low in risks."

China recently issued a new adaptation of climate change route map ("National Adaptation to Climate Change Strategy 2035") shows that the key tasks should now be shifted to use sensors and satellites to predict extreme weather more accurately. Analysts say that the maximum accurate period of weather forecasting is often about 10 days, but climate monitoring is a completely different category, which will help the prediction of severe floods and drought at least one month in advance.
