Staff reporter Dan Yan ShaoWei Wang On August 23, are on the occasion of the Limit of Heat of solar terms of lunar calendar. According to the folk statement, the Limit of Heat represent hot high temperature will be over soon. But a few days ago, Yunnan provincial meteorological observatory sends out orange high-temperature prewarning, should save still continuously 35 �� high temperature of some areas of Red River basin and billows deep blue river valley. Before this, up to August 2, Shanghai appear 18 day such as high temperature totally this year, than long-term high temperature double will it be 9 day day on average. Turfan of Xinjiang reaches 47.8 �� in the temperature on August 4, achieve the historical supreme value over the past 50 years. The main trend of the global warming lets everybody experience irresistible temperature. The expert predicts, from now to 2100, the global temperature on average will be raised by between 1.4 �� and 5.8 ��. Temperature and disease are concerned with in U shape " China tackles the national scheme of climatic change " that June 4 this year is released is proposed, climatic change may cause the increase of the heat wave frequency and intensity, will be increased by death toll and serious disease that the high-temperature incident cause extremely. Environment and safe chief's gold and silver dragon's introduction of relevant products of the health of Center for Disease Prevention and Control of China, from 1986 to 2007, our country has gone through 22 warms winter together. It is estimated by 2050, the average temperature of the whole year of our country will rise from 2.3 �� to 3.3 ��. Until climate become warm day by day, old man, children and suffer from respiratory system and the intersection of circulatory system and the intersection of disease and health of crowd, influence much. 2003, the gold and silver dragon has presided over a research project cooperating with Japan, study the impact on heart brain vascular disease, respiratory disease death and people's total death of climatic change in cities such as Harbin, Nanjing, Guangzhou,etc.. Discover tentatively, patient's mortality of vascular disease of the heart brain, respiratory disease and relation curve of the temperature take the form of U shape or V. It means the high temperature or low temperature can make the death increase. This is basically identical with Japanese result of study in Yokohama, Tokyo,etc.. In 2008, the gold and silver dragon will wait for someone to choose " stove " Wuhan of title the city is research object,finding climate characteristic statistical analysis of the past 6 years for city, when the maximum air temperature of this area is at over 36 ��, the death is counted and increased with the rising of the temperature notably. " hot day " (temperature is greater than equal toing by 36 ��) With " non- hot day " (temperature is lower than ��36) The ratio that crowd's death counts is 11.18. And it verifies, Shanghai, Guangzhou exceed 34 ��, Nanjing exceeds 35 �� to study previously, New York of U.S.A., Philadelphia exceed between 32 �� and 33 ��, will make the death count and increase notably too. Therefore, the researcher draws the conclusion, the high temperature can increase the danger of the population death, once exceeds critical value of some temperature, the human mortality will increase greatly. Study yet to reveal, old person and women's, men's death count, present the obvious peak from July 23 to August 9 over 60. Circulatory system and crowd's daily average death in the heat wave one of respiratory disease are counted, including not 1.91 times and 2.43 times of one of heat wave. "The human body has certain limit to the adaptive capacity of the meteorological condition. Human body's normal body temperature is realized through the fact that the organism regulates the dynamic equilibrium producing heat and dispelling the heat. The elderly's body temperature modulability and temperature sensitiveness are relatively bad, the time that the body heat regulation system is under the overloading state will be lengthened correspondingly during the high temperature, thus increase the danger that disease takes place or dies, the elderly who especially have respiratory system, vascular disease of heart brain on suffering from influence more obviously. " Jin YinLong says, though everybody's death has certain physiological reasons, it heats a lethal one to be minority while being simple, but hot weather will make damaged load of system to increase already, become a kind of external cause of facilitating the death. The healthy crowd will be influenced a research report delivered recently of " publication of institute of American Academy of Sciences " to point out indirectly, under the influence of global warming, it will make the human body lose moisture more easily that the temperature is raised, thus cause the urine amount to reduce, bring out kidney stone. This research has proved there are direct negative effects on human health in climatic change for the first time. As to conclusion this, YinLong Jin say, need further verifying but global warming that point out its and whether infectious disease concerned withing between the disease meriting attention also. He says: "Global warming can change meteorological conditions such as the rainfall, wind speed, humidity,etc., thus influence the air pollutant density. If the high temperature can make the ozone density in the earth's surface rise, people will lead to the fact the lung function obviously drops while exposed to ozone of high density for a long timing. In addition, global warming will cause the flood, arid,etc. the frequency take place and increase in the natural calamity, can initiate water to transmit disease, for instance infectious diseases such as the cholera, typhoid fever, first type hepatitis,etc. take place. The rising of river temperature will change the biochemical course of the water body, promote the offal in the river to decompose, alga and bacterium increases etc., and then make water quality drop, influence the health indirectly. " Gold and silver dragon point out global warming can enable some harmful substance in the air, pollen,etc. increase with temperature and humidity and the density increases for instance, make the morbidity of crowd's anaphylactia increase. The gas will lead to the fact the UV radiation in the sunshine increases to the destructiveness of the ozone layer in the greenhouse, can increase the morbidity of skin carcinoma, cataract,etc.. The regional climate changes warm parasitic, reproduction as the insect-pollination and pathogen with propagating and creating the condition continuously, have expanded its popular intensity and range. If the pathogen in the South may be moved to the North originally, the pathogen in the virgin forest may have entered crowds in the past. "That upset people most is that global warming may cause the getting rich quick of new infectious disease at present, cause the original virus to morph and produce new disease. " Expect that it shows, a lot of people think the thing of consideration that global warming is country, government or scientist to set up early warning system gold and silver dragon, and one's own relation is not big, this is wrong. The media should strengthen to the propaganda strength of the relation between global warming and human health, popularize climatic change and influence knowledge healthily, let them realize the intersection of climatic change and people correctly to the public, especially the impact on sensitive crowd, realize global warming to healthy danger. The more important thing is, our country should strengthen the policy to intervene, and increase input on setting up climatic change and human health monitoring, predicting early warning system and research in the new disease and preventing. At present, our country remains to strengthen global warming and healthy and relevant policy, regulation and system, hope to set up climatic change and human health monitoring, predict the early warning system. This system regards situations of impact on blood pressure, heart rate, lung function,etc. such as the temperature, atmospheric pressure, humidity,etc. as the theoretical foundation, its form can be similar to the weather bureau while predicting weather, remind the public to pay attention to increasing and decreasing the clothes or trying hard to avoid going out etc.. Relevant departments such as the hygiene,etc. should make good preparations for corresponding emergency in time according to the early warning rank. Therefore, no Can only strengthen public understanding, reduce or avoid the excess death that initiates because of global warming, can promote progress and implementation of work such as environmental pollution control, reduction of greenhouse gas discharge? ?
