Global Warming Is Harmful to HealthComputer models show that many diseases will surge as the earth's atmosphere heats up．Signs of the predicted troubles have begun to appear.Today few scientists doubt the atmosphere is warming．Most also agree that the rate of heating is increasing and that the consequences of this temperature change could cause more damagE.Even high school students can tell some outcomes: the oceans will warm and glaciers ( 冰川) will melt, causing sea levels to risE.Meanwhile the regions suitable for farming will shift．Weather patterns should also become stranger and storms more severE.Yet less familiar effects could be equally detrimental (有害的)．Notably, computer models predict that global warming, and other climate alternations it causes, will expand the influence and distribution of many serious medical disorders, Disturbingly, these forecasts seem to be coming truE.Heating of the atmosphere can influence health through several routes, Most directly,it can generate more, stronger and hotter heat waves, which will become especially dangerous if the evenings fail to bring cooling air．Unfortunately, a lack of nighttime cooling seems to be the casE.The atmosphere is heating unevenly and is showing the biggest rises at night, in winter and at latitudes higher than about 50 degrees．In some places, the number of deaths related to heat waves is projected to double by 2020． Prolonged heat can, moreover, enhance production of smoke and fog．Both effects have been linked to respiratory (呼吸道的) Symptoms．Global warming can also threaten human beings indirectly by causing rapid swings between flood and drought, which promotes, by various means, the emergence and spread of infectious diseasE.The prospect is deeply troubling, because infectious illness is monster that can be very hard to put back into its bottlE.It may kill fewer people in one time than a raging flood or a drought, but once it takes root in a community, it can hardly be erased and can invade other areas.Floods and drought associated with global climate change could undermine health in other ways as well．They could damage crops and make them vulnerable to infection,thereby reducing food supplies and potentially contributing to lack of nutrition.第 16 题 Most scientists doubted that global warming would cause serious damagE.A.RightB.WrongC.Not mentioned
