全球变暖和保护生态环境文章的中英文资料全球气温变暖的主要原因：人类活动对气候变化肯定是有变化和影响的。人类燃烧煤、油、天然气和树木，产生大量二氧化碳和甲烷进入大气层后使地球升温，大气中二氧化碳排放量增加是造成地球气候变暖的根源。Themainreasonforglobalwarming:humanactivitiesdefinitelyhaveanimpactonclimatechange.Humanburnscoal,oil,naturalgaswhichproducedalargeamountofcarbondioxideandmethane,anditwarmedtheearth.Thecauseofglobalwarmingistheincreasedcarbondioxideemissionsintotheatmosphere.造成的危害:首先是自然生态会发生变化；土地荒漠化，森林退向极地，雨量增加，冬天更湿，夏天更旱，旱涝灾害增加，热带将酷热无比，人类难以生存。其次是两极冰块大面积熔化，使海平面上升，那将使生活在沿海的占世界1/3的人口无家可归，世界许多港口城市淹没于一片汪洋之中。Harms:first,tochangethenaturalecology;landdesertification,forestbacktothepolarregions,increasedrainfallinwinter,wetter,moredroughtsinsummer,increaseddroughtsandfloods,tropicalwouldbeextremelyhot,humandifficulttosurvive.Second,themeltingpolarice,alargearea,sothatsealevelrise,whichwillliveincoastalareasoftheworld's1/3ofthepopulationhomeless,manyoftheworldportcitysubmergedinaseaof.由于人类活动的影响，中国的气候在21世纪将继续明显变暖，其中中国北方冬天的变暖趋势最为明显。作为对比，过去100年中，中国的升温幅度仅为0.5℃到0.8℃。由于气候暖干，三江平原湿地资源及生物多样性都将减少，濒危物种增加，大面积沼泽湿地将变成草甸湿地。长江三角洲附近的湿地，则将受到海平面上升的威胁，导致面积减少，质量下降，潮滩地被淹没和侵蚀。由于气温上升，导致黄河和内陆河地区的蒸发量可能增长15%左右，北方水资源短缺以及南方的洪涝灾害都将加剧。温度升高导致冻土融化，也会影响到青藏铁路的安全。Astheimpactofhumanactivities,theclimateinthe21stcenturyChinawillcontinuetosignificantlywarmer,whichinwinterwarmingtrendinnorthernChinathemostobvious.Incontrast,overthepast100years,China'stemperatureriseofonly0.5℃to0.8℃.AswarmanddryclimateintheSanjiangPlainwetlandresourcesandbiodiversitywilldecrease,anincreaseofendangeredspecies,largeareaswillbecomeameadowmarshwetlands.WetlandsneartheYangtzeRiverDelta,willbethethreatofrisingsealevels,resultinginreducedsize,lowerquality,tidalinundationandbeacherosion.Astemperaturesrise,leadingtotheYellowRiverandinlandriversoftheevaporationmayincreaseabout15%watershortageinnorthernandsouthernfloodswillincrease.Leadtopermafrostmeltingtemperature,alsoaffectthesafetyoftheQinghai-TibetRailway.由于人类活动的影响，中国的气候在21世纪将继续明显变暖，其中中国北方冬天的变暖趋势最为明显。作为对比，过去100年中，中国的升温幅度仅为0.5℃到0.8℃。由于气候暖干，三江平原湿地资源及生物多样性都将减少，濒危物种增加，大面积沼泽湿地将变成草甸湿地。长江三角洲附近的湿地，则将受到海平面上升的威胁，导致面积减少，质量下降，潮滩地被淹没和侵蚀。由于气温上升，导致黄河和内陆河地区的蒸发量可能增长15%左右，北方水资源短缺以及南方的洪涝灾害都将加剧。温度升高导致冻土融化，也会影响到青藏铁路的安全。Astheimpactofhumanactivities,theclimateinthe21stcenturyChinawillcontinuetosignificantlywarmer,whichinwinterwarmingtrendinnorthernChinathemostobvious.Incontrast,overthepast100years,China'stemperatureriseofonly0.5℃to0.8℃.AswarmanddryclimateintheSanjiangPlainwetlandresourcesandbiodiversitywilldecrease,anincreaseofendangeredspecies,largeareaswillbecomeameadowmarshwetlands.WetlandsneartheYangtzeRiverDelta,willbethethreatofrisingsealevels,resultinginreducedsize,lowerquality,tidalinundationandbeacherosion.Astemperaturesrise,leadingtotheYellowRiverandinlandriversoftheevaporationmayincreaseabout15%watershortageinnorthernandsouthernfloodswillincrease.Leadtopermafrostmeltingtemperature,alsoaffectthesafetyoftheQinghai-TibetRailway.人们过去一向认为，多种植树木有助于减缓全球气温升高的现象。不过，科学家如今指出，如果地球气温再升高2摄氏度，森林反而可能成为二氧化碳的净排放来源。植物会吸收也会排放二氧化碳；健康的森林，尤其是热带地区的森林所吸收的温室气体，会比它们排放的来得多。不过，如果这些森林受到破坏、生病或是死亡，蓄积在这些森林里的二氧化碳就会被释放出来。人类砍伐森林时进行的焚烧和摧毁所释放的温室气体，占了总碳排放量的20%森林可吸收四分之一的总碳排放量，随着它们日益消失，或是成为净排放来源，空气中的二氧化碳将大幅度增加。”Peopleusedtoalwaysthinkthat,morethanplantingtreeshelpslowglobalwarmingphenomenon.However,scientistshavenowpointedoutthatifglobaltemperaturesriseanother2degreesCelsius,theforestbutitmaybecomeanetcarbondioxideemissionsources.Plantsabsorbcarbondioxideemissionswillbe;thehealthofforests,especiallytropicalforestsabsorbthegreenhousegasemissionsthantheyaretomuch.However,iftheseforestsaredestroyed,illnessordeath,accumulationofcarbondioxideintheseforestswillbereleased.Whenhumanburningofdeforestationanddestructionofthereleaseofgreenhousegases,ofthetotalcarbonemissionsby20%oftheforestcanabsorbaquarterofthetotalcarbonemissions,astheyincreasinglydisappear,orbecomeanetsourceofemissions,carbondioxideintheairwillincreasesignificantly.从以上分析可以看出，影响气候变化的因素极其复杂，天体运行和地球运动的威力比人的影响不知要大多少倍，它可以使天气变热，也能让地球变冷。而人的力量在大自然面前显得非常渺小，连一场台风吹来也只有躲避的份儿，大自然的力量是根本抗御不了的。肆无忌惮地糟践自然，人类必然会受到严厉惩罚。人类应该尽一切努力，去做好应该也能够做好的事情。大力发展低碳经济已经成了国际社会的共识。Canbeseenfromtheaboveanalysis,impactofclimatechangeintheextremelycomplex,andtheearthmovementsofcelestialbodiesthanthehumanimpactunknownpowerbemanytimesgreater,whichcanmaketheweatherBianre,Yemaketheearthcooler.Thepowerofpeopleinfrontofitisverysmallinnature,withatyphoonblowingonlyescapetobutisthefundamentalforcesofnaturecannotresist.Brazenlyinsultingnature,mankindwillinevitablybeseverelypunished.Manshouldmakeeveryefforttodoagoodjobshouldalsobeabletodothings.Todeveloplow-carboneconomyhasbecometheconsensusoftheinternationalcommunity.从以上分析可以看出，影响气候变化的因素极其复杂，天体运行和地球运动的威力比人的影响不知要大多少倍，它可以使天气变热，也能让地球变冷。而人的力量在大自然面前显得非常渺小，连一场台风吹来也只有躲避的份儿，大自然的力量是根本抗御不了的。肆无忌惮地糟践自然，人类必然会受到严厉惩罚。人类应该尽一切努力，去做好应该也能够做好的事情。大力发展低碳经济已经成了国际社会的共识。Canbeseenfromtheaboveanalysis,impactofclimatechangeintheextremelycomplex,andtheearthmovementsofcelestialbodiesthanthehumanimpactunknownpowerbemanytimesgreater,whichcanmaketheweatherBianre,Yemaketheearthcooler.Thepowerofpeopleinfrontofitisverysmallinnature,withatyphoonblowingonlyescapet
