英语演讲环境温室效应

TheGreenhouseEffect

全球气候变暖，是到目前为止对地球和人类生存最为紧

迫也最为严重的威胁因素之一。

Globalwarmingisoneof

themosturgentandthemostseriousfactorsnowthreatenEarthandhuman'ssurvival

最近，全世界冰川融化速度创下历史最快纪录，从安第斯山脉到北极，冰川消融速度加快。

全球气候变暖将直接导致南、北极以及其它冰川融化，同时一些雪山也将随着气温的不断升高而消失。

而融化后的冰川，将使海平面快速上升，世界很多美丽的城市终将被海水所淹没。

Recently,Thespeedofmeltingglacierssettherecordforthefastest,fromtheAndestotheArcticglaciersmeltingfaster.GlobalwarmingwillleaddirectlytomeltingoftheAntarctic,theArcticandotherglaciers,Meanwhile,somesnow-cappedmountainswilldisappearwithtemperaturesrise.Theglaciersmeltedwillenablethesealeveltoriserapidly,manybeautifulcitiesintheworldwilleventuallybesubmerged.

100年后南极只曾留下回忆

乞力马扎罗山的“雪帽”将在15年内被摘掉

Kilimanjaro"snowcap"willbetakenoffin15years.

乞力马扎罗山是非洲最高的山脉，它距离赤道仅仅300

多公里，顶部却终年满布冰雪。

但是，全球变暖导致这座山的终年积雪不断消融，专家预言，“雪帽”将在15年内被

摘掉。

什么造成了温室效应

Whatcausesthegreenhouseeffect

我认为主要有两个原因：

人类排放二氧化碳和砍伐树木

Ithinktherearetwomainreasons:

humanemissionsofcarbondioxideandcutsdowntrees.

人类每秒钟释放的二氧化碳已经超过700吨，一年就是

230亿吨
