(2) American meteorologists' evaluation of the global average temperature change 1℃ is as follows: as the temperature rises 1℃, the economic benefits will also rise; When the temperature drops by 65438 0℃, the economic benefit will also drop. If the world average temperature drops by 1℃, the global output value will be reduced by 7 billion dollars.
③ The temperature change of1℃ has a more striking impact on agricultural production. Professor Dartsch of the United States believes that if the global temperature drops by 1℃ compared with the average temperature in the 1970s, 60% of the global corn harvest will increase by 2 1 10,000 USD; Cotton failed globally, with a loss of about $2.2 billion; 65% of the rice growing areas lost 956 million dollars. Zhang Jiacheng, a climatologist in China, studied and discussed the influence of the temperature rise and fall of 1℃ on China's grain crops: according to the test, the temperature change of 1℃ is roughly equivalent to the change of a crop's maturity level. Every time the maturity is changed, the yield changes 10%, which means that the temperature rises or falls 1℃, and the grain yield has the potential to increase or decrease 10%. For example, in the northeast of the famous commodity grain production base, if the average temperature in that year appears "cool summer", the grain production will definitely be reduced by 20 billion to 30 billion Jin. On the other hand, if there is a "hot summer", the grain can be collected by tens of billions of Jin.
④ Although the temperature rise 1℃ will increase the crop yield and economy, the environmental and social problems brought by the temperature rise are really worrying.
⑤ The latest report of relevant UN agencies predicts that if the global greenhouse gas emission reduction plan is not effectively implemented, the global average temperature will rise by 1.8℃ to 4℃ in 2/kloc-0 century. If this goes on, human beings will one day fall into the "heat trap" dug by themselves and cannot extricate themselves.
⑥ Experts predict that by 2030, China's sea level may rise by 1 cm to 16 cm, the probability of floods in the Yellow River Delta, the Yangtze River Delta and the Pearl River Delta will increase, and the harm of storm surges will also increase. As the temperature rises, the evaporation in the Yellow River and inland river areas may increase by about 15%, and the frequency of water shortage in the north and drought and flood in the south will also increase.
⑦ German criminal investigation experts also found that the crime rate began to rise in March every year, peaked in July and August, and began to decline in September. Statistical analysis: every time the temperature rises 1℃, the crime rate increases15%; When the temperature reaches 37℃, the red light stops for a long time, and the probability of quarreling between drivers is 30% higher than that at 32℃.
In recent years, global warming has aroused great concern all over the world. I believe that with the continuous development of science and technology, people's awareness of environmental protection is constantly enhanced, and through the joint efforts of * * *, we will certainly be able to protect our homeland.
