global warming,the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.
The temperature of the atmosphere near the earth's surface is warmed through a natural process called the greenhouse effect.Visible,shortwave light comes from the sun to the earth,passing unimpeded through a blanket of thermal,or greenhouse,gases composed largely of water vapor,carbon dioxide,methane,nitrous oxide,and ozone.Infrared radiation reflects off the planet's surface toward space but does not easily pass through the thermal blanket.Some of it is trapped and reflected downward,keeping the planet at an average temperature suitable to life,about 60掳F (16掳C).
Growth in industry,agriculture,and transportation since the Industrial Revolution has produced additional quantities of the natural greenhouse gases plus chlorofluorocarbons and other gases,augmenting the thermal blanket.It is generally accepted that this increase in the quantity of greenhouse gases is trapping more heat and increasing global temperatures,making a process that has been beneficial to life potentially disruptive and harmful.During the past century,the atmospheric temperature has risen 1.1掳F (0.6掳C),and sea level has risen several inches.Some projected,longer-term results of global warming include melting of polar ice,with a resulting rise in sea level and coastal flooding; disruption of drinking water supplies dependent on snow melts; profound changes in agriculture due to climate change; extinction of species as ecological niches disappear; more frequent tropical storms; and an increased incidence of tropical diseases.
Among factors that may be contributing to global warming are the burning of coal and petroleum products (sources of carbon dioxide,methane,nitrous oxide,ozone); deforestation,which increases the amount of carbon dioxide in the atmosphere; methane gas released in animal waste; and increased cattle production,which contributes to deforestation,methane production,and use of fossil fuels.
Much of the debate surrounding global warming has centered on the accuracy of scientific predictions concerning future warming.To predict global climatic trends,climatologists accumulate large historical databases and use them to create computerized models that simulate the earth's climate.The validity of these models has been a subject of controversy.Skeptics say that the climate is too complicated to be accurately modeled,and that there are too many unknowns.Some also question whether the observed climate changes might simply represent normal fluctuations in global temperature.Nonetheless,for some time there has been general agreement that at least part of the observed warming is the result of human activity,and that the problem needs to be addressed.In 1992,at the United Nations Conference on Environment and Development,over 150 nations signed a binding declaration on the need to reduce global warming.
In 1994,however,a UN scientific advisory panel,the Intergovernmental Panel on Climate Change,concluded that reductions beyond those envisioned by the treaty would be needed to avoid global warming.The following year,the advisory panel forecast a rise in global temperature of from 1.44 to 6.3掳F (0.8鈥?.5掳C) by 2100 if no action is taken to cut down on the production of greenhouse gases,and a rise of from 1 to 3.6掳F (0.5鈥?掳C) even if action is taken (because of already released gases that will persist in the atmosphere).
A UN Conference on Climate Change,held in Kyoto,Japan,in 1997 resulted in an international agreement to fight global warming,which called for reductions in emissions of greenhouse gases by industrialized nations.Not all industrial countries,however,immediately signed or ratified the accord.In 2001 the G.W.Bush administration announced it would abandon the Kyoto Protocol; because the United States produces about one quarter of the world's greenhouse gases,this was regarded as a severe blow to the effort to slow global warming.Despite the American move,most other nations agreed later in the year (in Bonn,Germany,and in Marrakech,Morocco) on the details necessary to convert the agreement into a binding international treaty,which came into force in 2005 after ratification by more than 125 nations.
Improved automobile mileage,reforestation projects,energy efficiency in construction,and national support for mass transit are among relatively simpler adjustments that could significantly lower U.S.production of greenhouse gases.More aggressive adjustments include a gradual worldwide shift away from the use of fossil fuels,the elimination of chlorofluorocarbons,and the slowing of deforestation by restructuring the economies of developing nations.In 2002 the Bush administration proposed several voluntary measures for slowing the increase in,instead of reducing,emissions of greenhouses gases

对于宣传全球变暖危害的朋友们,当我们将这些全球变暖所带来的影响摆给别人看,我们是否有十足的底气,可以让对方有同样的危机感?
从我个人来看,这些东西,基本上对一个不了解全球变暖的正常人来讲,一点关系都没有。这些事情和我们日常生活有什么直接影响和关系?几乎一点都没有!顶多是冬天少穿点衣服,夏天多开一会空调,偶尔太热了单位学校还给放假,这不是挺好嘛。按这样的好处来看,越热越好!把老弱病残都热死了,还可以减少污染呢。
那我们凭什么,要靠上面的这些东西,来让其他人在乎全球变暖?
这说明了一个极其严重的问题——我们的沟通能力有问题——我们逆行着,走进了一条单行线。
我们只考虑到了自己的价值观,而没有考虑到其他人的感受。这无论从哪个方面来说,都是一个极大的错误。
全球变暖所带来的,不仅仅只是我们常说的那几条,还有许许多多的影响,是同人类生活有直接密切关系的。为什么我们没有将这些讲给别人听?
·气温升高,会给人类生理机能造成影响,人类生病的几率将越来越大,各种生理疾病将快速蔓延,甚至会滋生出新疾病。眼科疾病、心脏类疾病、呼吸道系统疾病、消化系统类疾病、病毒类疾病、细菌类疾病……人们社会在医疗上所支付的金钱将越来越多,死于非命的人将越来越多。癌症,将越来越普及;促死,将会越来越普遍。再多的钱,再好的医生,也未必能救得了你的命;
·气温升高所带来的热能,会提供给空气和海洋巨大的动能,从而形成大型,甚至超大型台风、飓风、海啸等灾难。我们每年所遭受和面临的灾难越来越多,损失的生命和金钱数目越来越大,越来越让人难以接受。再多的钱,也未必能救得了你的命;
·台风海啸等灾难不单会直接破坏建筑物和威胁人类生命安全,而且会带来许多次生灾难,尤其是台风、飓风等灾难所带来的大量降雨,会导致泥石流、山体滑坡等,严重威胁了交通安全和居民生活安全;
·气温升高不单会从海洋直接吸取水分,还会从陆地吸取水分,使得内陆地区大面积干旱,从而粮食减产,饲料也一定会减产。粮食和肉类食品将面临匮乏,直接威胁国家稳定。为食物而引起的恐慌和争斗,将不再是落后村落中才会发生的事;
·气温升高所融化的冰山,正是我们赖以生存的淡水最主要的来源。我们的地下淡水储备都是由冰山融水组成的。在气温平衡正常时,冰山有一个冰雪循环系统,即,冰山夏天融化,流向山下,流入地下,给平原地区积累淡水,并起到一个过滤作用。冬天水分以水蒸气的形式回到山上,通过大量降雪重新积累冰雪,也是一个过滤过程。这整个的循环过程,使得我们的淡水有了稳定的平衡保障。而现在全球变暖使得冰山上的冰雪积累的速度远没有融化的速度快,甚至有些冰山已经不再积累,这就断绝了当地的饮用淡水。这将会带来因缺水而产生的冲突和战争;
·气温升高使得自然界食物链逐渐断裂。
·大气中二氧化碳含量上升,会导致海洋中二氧化碳含量上升,使海洋碳酸化,这会杀死大量微生物。最底层的食物消失,将使海洋食物链从最底层开始,向上迅速断裂,并蔓延至海洋以外。由于没有了食物,将有大量海洋生物,和以海洋生物为食的其他生物死亡。海洋中大量生物死亡,将会污染海洋,加速其他生物的死亡;同时释放大量温室气体,加速全球变暖,形成恶性循环;
·温度的上升,无脊椎类动物,尤其是昆虫类生物提早从冬眠中苏醒,而靠这些昆虫为生的长途迁徙动物却无法及时赶上,错过捕食的时机,从而大量死亡。昆虫们提前苏醒,因为没有了天敌,将会肆无忌惮地吃掉大片森林和庄稼。没有了森林,等于无形当中增加了二氧化碳的含量,加速全球变暖,形成恶性循环;没有了庄稼,就等于人类没有了食物;
·而蜜蜂数目的大量减少,也是自然界食物链彻底崩溃的前兆。没有了蜜蜂帮助传播花粉,植物将无法繁殖。也就是说,庄稼无法繁殖,无法结果,人类将没有食物。全球人类将面临食物短缺,为争夺食物而引发的战争将越来越多,越来越近。而供我们争夺的食物,也将越来越少;
·全球变暖导致陆地水分大量流失,随时会有“星星之火可以燎原”。不光是森林中的山火,城市中的火灾也将会非常频繁。大火无情,我们的家将24小时处于危险当中。我说24小时,就是说即使在夜间也会有发生火灾的可能。
·全球变暖所能确定的并公开的最大威胁,是冰河时代的突然降临。对这一结果不了解的朋友,可以去看一下《后天》这部电影,其内容就是讲述冰河时代降临的恐怖。但这部片子只做成了灾难片,而几乎没有起到多大教育意义。我都只有在看第二遍时才察觉到在电影开头时,讲到了全球变暖和冰河时代的关系。跛脚的美国灾难片;
全球变暖所带来的最恐怖的结果,也是未确定(?)未公开的结果,那就是,由于全球变暖所带来的海啸等海洋性灾难次数越来越频繁,规模越来越大,所带来的次生灾难也越来越多,规模越来越大。当海洋性灾难达到一个最高点时,也就是量变产生质变的那一点时,部分地壳被海洋所撼动,造成地震,而部分地壳附近的火山被引发,连锁反应,来带更大的地震,从而产生更大规模的火山爆发。火山爆发所产生的数万吨上千摄式度的火山灰,所到之处,便是火海,即使没有点燃的,也被压扁。世界上近八成的人口将在这次火山爆发中消失。待火山平静下来,大量冷却的火山灰掩盖天空,将有至少长达两年之久的黑暗生活笼罩整个世界。没有阳光就没有植物,也就没有粮食。坚持到最后的,恐怕只有老鼠和小强。
大家对全球变暖所带来的这一类的后果有什么样的感受?和之前我们经常听到见到提到的有什么不同?一个是别人抱炸弹,一个是自己抱炸弹。相信大家和我的感受会很相似。
大家都是热爱生活的人,都是充满爱心的人,都是肯为环保事业奉贤自己力量的可爱的人。但我们只是在宣传环保时,忘却了一点,那就是对方的感受。如果我们可以对对方的心理进行推敲,拿捏,在了解了对方后,再通过恰当的方式进行宣传,宣传效果岂不会更加理想?对症下药,这是无论在哪里都适用的完用理论。
我相信,如果我们能将全球变暖所带来的更震撼人心的影响,告诉周围人的话,那么,大家必定会重新审视环保的重要性,并发自内心地为自己、为家人、为朋友、为地球奉贤出一份力量!
