第一篇：全球變暖英文資料Globe warming

As we all know, there is a big problem on the earth, ‘Globe warming’.It is related to human’s survival, so we should know the whole system of the earth, then we will understand why the warming will destroy and kill the life.Glacier ice exists on all the continents except Australia.Mountain glaciers, in particular, are very sensitive indicators of climate change, the glaciers and the ice serve many functions.Firstly, during the Arctic winter, the air is colder than the water, the ice helps to insulate the water from the atmosphere, where there is no ice there’s a huge heat flow from the water to the atmosphere, which causes the air temperature to go up;Secondly, the ice also restricts the energy of the wind from causing waves near the ice, that’s why ships often stay near the ice, where the seas are calmer;Thirdly, the ice also acts as a mass exchange preventing ocean water from evaporating into the atmosphere, and since ice is white, it reflects the sun’s energy and keeps the system cool, without ice, the temperature of the earth would be likely to increase, perhaps significantly.Even a modest of 2 to 4 degrees, Fahrenheit could have a profound effect, some regions of the world might experience more rainfall which leads to floods, which would have impact on agriculture and forest growth.Fertile wet lands could be lost due to rises in sea level, and low-lying areas might experience flooding from melting water run off, higher temperatures in most areas of the world could become fertile breeding grounds.So, we

could see malaria in areas of the world where it never existed before.What cause the temperature goes up? There are many things affecting the balance of temperature.Such as ‘precipitation’, humidity’, ‘wind speed’, ‘slope’, and ‘reflectivity’, which we call natural phenomenon.Except those things, there is a major thing, ‘human activity’, for example, ‘fossil fuel’, there is an evidence of melting data which suggests that since 1850 some alpine glaciers have lost between 30% and 40% of their surface area and about 50% of their volume, similar findings have been reported in other glaciers around the world.Global compilations show that sea level has risen about 1/10 of an inch per year, which may not sound like a lot, but by the year 2100, sea level may rise by almost two feet, if this warming trend continues.So what we should do to protect our planet? We should follow the advice, ‘car pool’, ‘using transportation’, ‘by bike’, ‘planting trees’, and so on.

第二篇：全球變暖原因 英文

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.Some of the reasons for global warming, mainly divided into two aspects of both human factors and natural factors： Human Factors：

1、Population factors

In recent years, the dramatic increase in population is one of the main factors that contribute to global warming.At the same time, it also seriously threatens the balance between natural ecological environment.So many people, only their own emissions of carbon dioxide each year will be a staggering Numbers, the result will lead to make the content of carbon dioxide in the atmosphere directly increase unceasingly, this form of carbon dioxide “greenhouse effect” will directly affect the earth's surface climate change.2、Atmospheric environmental pollution factors

At present, the increasingly serious environmental pollution has constituted a major global problem, is also one of the main factors that contribute to global warming.Now, on global climate change research has clearly pointed out that since the end of last century had started to rise the temperature of the earth's surface.3、Marine ecological environment deterioration factors

At present, the change of sea level is continuously rising, according to experts predict the next century, sea level could rise 50 cm.If you don't take on the measures, will directly cause the destruction of freshwater resources and pollution.In addition, land activities to produce large amounts of toxic chemical waste and solid waste constantly into the sea;Major in sea water in the oil(leak)events and caused by human activities such as coastal areas such as the destruction of the ecological environment is the main factor that leads to the ecological environment destruction.4、Land erosion, salinization, desertification and other factors

Land erosion, salinization, desertification and other factors, human activities such as for wood and deforestation, cultivated land used for agricultural production and overgrazing reason, is still a serious damage to vegetation.The world per minute on average 20 hectares of forest are destroyed, 10 hectares of land desertification, 47000 tons of soil erosion.Soil erosion decreased soil fertility and water retention, thus reducing the biological productivity of the soil and its ability to maintain productivity;And can cause a wide range of floods and dust storms, causing great economic losses to the society, and the worsening ecological environment.5、The forest resources in factors

Around the world, because of natural or man-made factors causing forest area is greatly reduced.6、Acid rain harm factors

The effects of acid rain to the ecological environment has become more and more attention all over the world.Acid rain can destroy forest, acidification lakes, endanger biological, etc.At present, the acid rain in the world more concentrated in Europe and North America, most of the acid rain occurred in developed countries, some developing countries, acid rain, also in the occurrence and development rapidly.7.、Factors accelerate extinctions Life on earth is a valuable human resources, and biodiversity is the foundation of human survival and development.But now the biological species on the earth are shrinking at an unprecedented rate.8、Water pollution factors

According to the global environment monitoring system for water quality monitoring project shows that about 10% of the global monitoring of the pollution of the river, since this century, the human water consumption is dramatically increased, at the same time, water pollution, scale is continually expanding, this creates a contradiction between supply and demand of fresh water.Therefore, the treatment of water pollution is very urgent and important.9、Toxic waste pollution factors

Growing toxic chemicals not only pose a serious threat to human survival, but also to the ecological environment of the earth's surface will lead to harm.10、Human activities

Since the industrial revolution, human activities widely changed the shape of the earth's surface and the distribution of plants and animals, especially the extensive use of fossil fuels and other ways to discharge a large amount of greenhouse gases into the atmosphere.This makes the original content of greenhouse gases in the atmosphere of increased;Also added some originally not in the atmosphere, has strong greenhouse gases, such as CFCS and HFCS, PFCS [2].With the increase of greenhouse gas concentrations in the atmosphere, atmosphere further hindered the launch of the long wave radiation, the earth into space to keep the radiation balance, will heat up on the ground, in order to enhance longwave radiation.But the surface temperature will not continue to rise, corresponding to the concentration of greenhouse gases, will reach a new equilibrium.Natural Factors

1、The world is in a warm period.2、The earth periodic track changes

The earth periodic track by oval into circular trajectory, distance closer to the sun.According to some scientists study the earth's temperature has a moderate high low temperature alternating, there is a certain regularity.The China meteorological administration, deputy director of the national climate center, said luo according to many scientists predict that in the world in the next 50-100 human will completely into a warming world.Because of the influence of human activity in the 21st century, the concentration of greenhouse gases and sulphate aerosols increase quickly, make the future of the world in 100, east Asia and China's temperature is rising rapidly, the global average surface temperature to rise 1.4 ℃ to 5.8 ℃.To 2050, the average temperatures would rise by 2.2 ℃.“Frequent rare heavy fog weather since winter is also a sign of warmer winters.” Luo said that the fog weather is due to “warm winter” cause strong cold air is very weak.The reality of global warming is to ring alarm bells around the world, climate warming has the serious influence to human survival and sustainable development of society, it is not only a matter of science, and it is a political, economic, energy and other aspects of the comprehensive problem, the fact that global warming has risen to the height of national security

第三篇：英語(yǔ)全球變暖

Nowadays,we always hear about global warming on TV,in the newspaper and so on.Global warming occurs when heat-trapping gases, such as carbon dioxide, get trapped in the atmosphere, causing the Earth's temperature to rise.The emission of green house gases is believed to be one of the reasons for global warming.The main cause of global warming is human pollution,such as people cut down many trees recently,so trees could not absorb the carbon dioxide as much as possible.The balance of nature and ecological environment has been broken,it has a bad influence on our life.We must take measures to protect our earth.First,human must stop deforesting,and more tree planting.Second,we should save fossil fuels as far as possible,and developing new fuels to take place fossil fuels.Third,reduce,reuse,recycle.Recycling a stack of newspapers only four inches high will save a good sized tree.More importantly, we should form the habit of saving energy in our daily life.We hope the situation will soon change.We cannot wait any longer.Do it.Do it right.Do it right now.

第四篇：全球變暖原因

全球變暖的原因

資料來(lái)源：

http:// 新華網(wǎng)綜述：隨著全球人口的急劇增長(zhǎng)、世界經(jīng)濟(jì)的高速發(fā)展、人類(lèi)對(duì)自然資源的無(wú)節(jié)制開(kāi)發(fā)和生態(tài)環(huán)境的日益惡化，自上世紀(jì)70年代起，全球氣候已明顯變暖。但導(dǎo)致全球氣候變暖的真正原因是什么？科學(xué)家們似乎尚無(wú)定論，盡管它對(duì)全球經(jīng)濟(jì)發(fā)展和人類(lèi)社會(huì)活動(dòng)的影響無(wú)疑是巨大的，但對(duì)它們的評(píng)估務(wù)必謹(jǐn)慎，因?yàn)檫@是人類(lèi)應(yīng)對(duì)全球氣候變化決策的依據(jù)。

全球變暖的原因眾說(shuō)紛紜

全球變暖致家園告急

據(jù)新的科學(xué)研究顯示，目前地球正變得越來(lái)越熱的原因是，太陽(yáng)輻射處于近一千年來(lái)最強(qiáng)烈的時(shí)期。著名的馬克斯·普朗克太陽(yáng)能系統(tǒng)研究所的負(fù)責(zé)人薩米·索蘭基博士認(rèn)為：“這一點(diǎn)現(xiàn)在可能影響到了全球溫度。”

索蘭基博士說(shuō)，強(qiáng)烈的太陽(yáng)輻射，以及高水平的溫室氣體，這兩個(gè)因素共同導(dǎo)致了地球溫度的變化，但他說(shuō)不準(zhǔn)哪個(gè)因素對(duì)全球變暖的影響更大一些。

在過(guò)去幾十年中，大多數(shù)科學(xué)家都同意溫室氣體效應(yīng)導(dǎo)致了全球變暖，但對(duì)太陽(yáng)輻射增強(qiáng)是否也是全球變暖的一個(gè)因素存疑。

為了確定太陽(yáng)對(duì)全球變暖的影響，索蘭基博士的研究組對(duì)太陽(yáng)耀斑進(jìn)行了測(cè)量。他們還分析了過(guò)去幾百年的太陽(yáng)耀斑數(shù)據(jù)，終于發(fā)現(xiàn)：太陽(yáng)耀斑較少的年份，往往對(duì)應(yīng)于地球的一個(gè)低溫期—這一時(shí)期可能長(zhǎng)達(dá)50年 — 但上世紀(jì)，太陽(yáng)耀斑的數(shù)量明顯增多，地球的溫度也穩(wěn)定上升。

但索蘭基博士不知道是什么原因引起太陽(yáng)輻射增強(qiáng)，也不知道這一過(guò)程將持續(xù)多長(zhǎng)時(shí)間。他說(shuō)，過(guò)去20年中太陽(yáng)輻射的增強(qiáng)還不足以引起地球上所發(fā)生的氣候變化，他相信，太陽(yáng)輻射增強(qiáng)對(duì)臭氧層和云層的影響給氣候帶來(lái)的變化可能比太陽(yáng)光本身造成的影響更大。

瑞士皇家氣象學(xué)會(huì)成員、氣候?qū)W家比爾·伯羅斯博士對(duì)索蘭基博士的研究成果表示贊賞。他說(shuō)：“這一研究顯然是非常有價(jià)值的。它表明值得對(duì)太陽(yáng)進(jìn)行進(jìn)一步的研究。在我們還沒(méi)有確信人類(lèi)活動(dòng)是造成氣候變化的主要原因之前，我們也許把太多的注意力放在了人類(lèi)活動(dòng)對(duì)氣候的影響上。”

不過(guò)，英國(guó)氣象局的氣候研究員加雷思·瓊思博士說(shuō)：“太陽(yáng)輻射可能的確對(duì)氣候變化造成了影響，但這一因素需要與其他因素結(jié)合起來(lái)看?！?/p>

對(duì)全球氣候變暖的評(píng)估被夸大了

據(jù)美國(guó)航空航天局(NASA)的研究發(fā)現(xiàn)，過(guò)去的某些氣候預(yù)測(cè)夸大了對(duì)全球氣候變暖這一現(xiàn)象的評(píng)估。該局的模擬研究發(fā)現(xiàn)，過(guò)去人們對(duì)地球氣溫升高進(jìn)入地球大氣層的水蒸氣的數(shù)量估計(jì)過(guò)高。

許多科學(xué)家們信奉的理論認(rèn)為，由于人類(lèi)活動(dòng)產(chǎn)生的大量二氧化碳等溫室氣體迅速增多，地球氣候不斷變暖，海洋中的更多水分被蒸發(fā)到大氣層中。NASA指出，溫室效應(yīng)是否存在、其影響范圍究竟有多大等問(wèn)題，不同的科學(xué)家仍持有不同的

看法。上述最新研究結(jié)果表明，大氣層中的水蒸氣數(shù)量的確比以前增多了，但遠(yuǎn)沒(méi)有氣候預(yù)測(cè)計(jì)算機(jī)所說(shuō)的那樣神乎其神。

NASA的科學(xué)家德斯勒表示，科學(xué)的責(zé)任之一，就是對(duì)未來(lái)的氣候做出比較準(zhǔn)確的預(yù)測(cè)，因?yàn)檫@種預(yù)測(cè)是決策者們制定政策的依據(jù)。

我國(guó)氣象學(xué)家王明星也認(rèn)為：對(duì)于氣候變化的影響的評(píng)價(jià)問(wèn)題很多、很復(fù)雜。這首先表現(xiàn)為到目前為止，還沒(méi)有形成統(tǒng)一的客觀的科學(xué)評(píng)價(jià)體系。氣候變化的影響是多方面的，“影響評(píng)價(jià)”的尺度標(biāo)準(zhǔn)是十分復(fù)雜而難以定量的。當(dāng)前研究較多的是對(duì)農(nóng)業(yè)生產(chǎn)，森林和其它生態(tài)系統(tǒng)的影響。研究結(jié)果基本上都是定性的描述，而且，有些定量結(jié)果也都是很粗的估計(jì)值。

王明星說(shuō)，關(guān)于氣候變化影響評(píng)價(jià)的不確定性的另一原因，是所依據(jù)的氣候變化預(yù)測(cè)結(jié)果的極不確定性。關(guān)于未來(lái)氣候變化預(yù)測(cè)結(jié)果中只有全球平均地表溫度一項(xiàng)是可以接受的。關(guān)于氣溫變化的空間分布，降水變化及氣候極端事件的預(yù)測(cè)都是很不確定的。

然而，對(duì)于氣候變化的影響評(píng)價(jià)來(lái)說(shuō),恰恰需要各地區(qū)的氣溫變化，降水變化，氣候極端事件變化等。人們不難理解，對(duì)于氣溫很高降水豐富的熱帶和亞熱帶地區(qū)，氣溫上升1－2度對(duì)農(nóng)業(yè)和其它生態(tài)系統(tǒng)的影響可能并不明顯，而對(duì)于氣溫偏低，降水相對(duì)較多的冷溫帶地區(qū)，氣溫上升對(duì)農(nóng)業(yè)和生態(tài)系統(tǒng)的影響總體上反而是有利的；而對(duì)于氣溫適中，降水相對(duì)偏少的暖帶大多數(shù)地區(qū)，氣候變化的影響顯然主要取決于降水的變化，在這些地區(qū)如果氣溫上升，伴隨著較大幅度的降水增加，則氣候變化對(duì)農(nóng)業(yè)和其它生態(tài)系統(tǒng)顯然是有利的。相反，氣溫上升降水不增加甚至減少，氣候變化對(duì)農(nóng)業(yè)和其它生態(tài)系統(tǒng)將造成災(zāi)難性結(jié)果。

全球氣候變化的“周期性”說(shuō)

在美國(guó)舊金山舉行的2004年美國(guó)地球物理學(xué)會(huì)的年會(huì)上，美國(guó)冰河學(xué)家朗尼·湯普森聲稱(chēng)，他通過(guò)對(duì)許多氣象記錄中的一些標(biāo)志性數(shù)據(jù)的研究表明：大約在5200年前，地球的氣候突然發(fā)生了變化，而這種變化今天似乎又在重復(fù)出現(xiàn)。

湯普森在他的研究報(bào)道中列舉了一系列有趣的實(shí)例：1991年，在阿爾卑斯冰川，登山者在融化的冰川中發(fā)現(xiàn)了一個(gè)保存完好的男子尸體。之后的測(cè)試結(jié)果顯示，這個(gè)被實(shí)驗(yàn)室人員稱(chēng)作“奧茲（Oetzi）”的男子大約是在5200年前被困于此的。

來(lái)自愛(ài)爾蘭和英國(guó)的一項(xiàng)橫跨了7000年歷史的樹(shù)年輪研究表明，大約在5200年前，樹(shù)年輪是最密集的，這表明了那些樹(shù)所經(jīng)歷的最干旱時(shí)期也大約是在5200年前。

借助氧的兩種同位素，湯普森還引用了非洲乞力馬扎羅山頂?shù)谋尫潘俣鹊谋擞涗洝＿@些記錄能夠顯示降雪時(shí)大氣的溫度。記錄表明，在距今5200年前溫度是最低的。

此外，湯普森還列舉了撒哈拉沙漠從一個(gè)可居住的地區(qū)到一個(gè)荒蕪的沙漠的

變化、在南美的湖床中心發(fā)現(xiàn)的植物花粉的重大變化、以及在格陵蘭和北極從冰核中釋放的甲烷的最低的水平記錄，所有的一切都發(fā)生在同一時(shí)間，5200年前。

湯普森說(shuō)，所有的這些證據(jù)都清楚地指向歷史上的這一時(shí)間，以及發(fā)生的某個(gè)事件，這同樣也指出類(lèi)似的變化可能正在今天的氣候中發(fā)生。

湯普森相信，5200年前的變化可能是由于到達(dá)地球的太陽(yáng)能量劇烈波動(dòng)引起的?？茖W(xué)家們已經(jīng)知道了歷史上曾經(jīng)存在一個(gè)全球冷卻期，在公元1450年到1850年之間，并把那個(gè)時(shí)期稱(chēng)為“小冰期”，與太陽(yáng)活動(dòng)減弱的兩個(gè)時(shí)期重合。

證據(jù)顯示，大約在5200年前，太陽(yáng)能量輸出首先出現(xiàn)急劇下降，然后在一小段時(shí)間內(nèi)上升。湯普森認(rèn)為，正是這種巨大的能量振動(dòng)引發(fā)了他本人在所有記錄中看到的氣候變化。

湯普森指出，天氣系統(tǒng)對(duì)自然界的變化十分敏感。同樣地，它對(duì)于人類(lèi)活動(dòng)帶來(lái)的影響也同樣敏感，比如溫室氣體的增加、土地利用政策的變化和對(duì)于不可再生能源的依賴(lài)，都會(huì)給天氣系統(tǒng)造成影響。

為此，湯普森強(qiáng)調(diào)指出：“我們還沒(méi)有能夠完全了解天氣系統(tǒng)的復(fù)雜性。正因?yàn)槲覀儾欢?，我們就?yīng)當(dāng)非常謹(jǐn)慎地評(píng)估。”

第五篇：全球變暖 觀后感

《難以忽視的真相》觀后感

農(nóng)經(jīng)1班

劉恬園

今天，老師組織我們看《難以忽視的真相》這部電影，我開(kāi)始對(duì)這部電影很好奇，看過(guò)之后，我才深深感受到溫室效應(yīng)所帶給我們的危害，這是我之前從未思考過(guò)的，冰川融化，動(dòng)物失去了它們的家園，瀕臨滅絕；而帶給我們不斷地自然災(zāi)害，干旱，洪澇和颶風(fēng)等自然災(zāi)害，在災(zāi)難中，給人類(lèi)帶來(lái)精神壓力和財(cái)產(chǎn)損失，一次次襲擊著我們，考驗(yàn)著我們；在某些地方，還可能發(fā)生不知名的物質(zhì)運(yùn)動(dòng)，我們應(yīng)該予以注意?，F(xiàn)在，我們應(yīng)該學(xué)會(huì)如何去預(yù)防這些災(zāi)難的發(fā)生。

原來(lái)，我總是認(rèn)為全球變暖就是單純的各地溫度的升高，在看完影片后，我認(rèn)識(shí)到了全球變暖所帶給我們的危害，北極熊即將沒(méi)有棲息地，人類(lèi)也將失去他們美好的地球家園，在數(shù)據(jù)的分析統(tǒng)計(jì)下，我們應(yīng)該引起重視，重視全球變暖對(duì)我們的日常生活的變化，不要等有朝一日，我們的生態(tài)環(huán)境變得不好時(shí)，才讓我們后悔莫及，我們應(yīng)該呼吁更多的人來(lái)了解溫室效應(yīng)，了解全球變暖，知道它們所即將帶來(lái)的災(zāi)難，我們每個(gè)人都是地球的一份子，每個(gè)人都應(yīng)該為地球的美麗與健康做出一份貢獻(xiàn)，地球是我們賴(lài)以生存的家園，我們祖祖輩輩生活在這里，讓我們共同來(lái)保護(hù)它——地球。全球變暖是由于二氧化碳排放過(guò)多引發(fā)溫室效應(yīng)而造成的，在我們?nèi)粘Ｉ钪?，我們可能觀察生活環(huán)境變化的不大，并沒(méi)有影響我們的日常生活，但殊不知，在地球的某一端，生態(tài)環(huán)境卻在發(fā)生著巨大的變化，全球變暖，是多么可怕的事情呀，如果人類(lèi)再不引起重視和實(shí)施防護(hù)措施，也許，在不遠(yuǎn)的將來(lái)，地球只剩人類(lèi)這個(gè)唯一生存的生物，試想，我們能生存下去嗎？

在如今這個(gè)快節(jié)奏的21世紀(jì)，科技越來(lái)越發(fā)達(dá)，人們的生活變得方便快捷，在享受科技帶給我們的便捷的同時(shí)，又有誰(shuí)在想著科技也同樣帶給我們一系列的生態(tài)問(wèn)題，這就是人類(lèi)改造自然的結(jié)果嗎？一草一木并不會(huì)說(shuō)些什么，但在不遠(yuǎn)的將來(lái)，一系列的生態(tài)問(wèn)題又有誰(shuí)來(lái)解決呢？在現(xiàn)如今這個(gè)社會(huì)，為了利益與金錢(qián)，不惜犧牲生態(tài)環(huán)境來(lái)賺得利潤(rùn)的人太多太多，我們應(yīng)該呼吁倡導(dǎo)節(jié)能減排，讓每個(gè)人了解生態(tài)危害，防治生態(tài)污染的發(fā)生，這是我們每個(gè)人都應(yīng)盡的一份責(zé)任，大家不需要盡多大的力量去做，從身邊的一點(diǎn)一滴小事做起，種植植物，少開(kāi)私家車(chē)，多乘坐公共交通工具，這樣的小事，既環(huán)保又能鍛煉身體，何樂(lè)而不為呢，我們都應(yīng)該行動(dòng)起來(lái)，傳遞保護(hù)生態(tài)環(huán)境的正能量，為了地球家園，讓我們都行動(dòng)起來(lái)吧！為了更好的生活環(huán)境而努力，控制二氧化碳，保護(hù)我們的家園，創(chuàng)造更優(yōu)的生活環(huán)境，給地球的每個(gè)人一個(gè)整潔的藍(lán)色地球。

在不少大城市中，環(huán)境污染已經(jīng)成為當(dāng)前面臨的一大關(guān)鍵問(wèn)題，環(huán)境污染，生態(tài)破壞，這些不斷的發(fā)生在我們身邊的每一處，隨處可見(jiàn)的白色污染，地上充斥著剛剛吐完的痰跡，路人剛剛?cè)咏o的包裝袋，遠(yuǎn)處煙囪中剛剛排放出的污染物，這些生活中的事例還有許多許多，難道不足以引起我們的重視嗎？善待我們的家園，善待我們的地球，共創(chuàng)一個(gè)美好的生活環(huán)境。與此同時(shí)，大氣環(huán)境正在一步步惡化，未來(lái)氣候還會(huì)變暖，變暖的停滯現(xiàn)象可能還會(huì)持續(xù)一二十年，甚至還要更短的時(shí)間，中國(guó)處于經(jīng)濟(jì)快速發(fā)展的階段，煤，石油，天然氣，各種能源的使用，排放的二氧化碳增多。導(dǎo)致全球地表平均溫度增高了0.85度，其中北半球高于南半球，冬半年升溫高于夏半年，在過(guò)去的130年來(lái)全球升溫0.85度，全球變暖體現(xiàn)在全球氣溫升高,海洋變暖，冰雪大范圍融化，海平面持續(xù)上升等各個(gè)方面，人類(lèi)對(duì)氣候系統(tǒng)的影響越來(lái)越明顯；人類(lèi)對(duì)氣候的干擾越大，人類(lèi)所面臨的風(fēng)險(xiǎn)就越高；人類(lèi)可以采取更多的措施限制減緩氣候變化，建立一個(gè)更加繁榮可持續(xù)的未來(lái)。人類(lèi)對(duì)氣候系統(tǒng)的影響非常明顯，人類(lèi)活動(dòng)排放的溫室氣體指標(biāo)目前達(dá)到史上最高水平。最近氣候變化對(duì)自然系統(tǒng)的狀況造成了強(qiáng)烈影響，氣候變暖已不容置疑。如果未來(lái)不采取必要措施減少二氧化碳排放，那么變暖現(xiàn)象完全有可能持續(xù)，而21世紀(jì)末以前可能會(huì)導(dǎo)致出現(xiàn)“嚴(yán)重且不可逆轉(zhuǎn)的后果”。我們都不希望地球是這樣的，人類(lèi)面對(duì)地球生態(tài)環(huán)境快速惡化的風(fēng)險(xiǎn)，每個(gè)人必須盡快行動(dòng)，降低溫室氣體排放，否則將引發(fā)生態(tài)和社會(huì)災(zāi)難。

北京這座大城市，已經(jīng)受到了大氣的污染，霧霾的一次次來(lái)襲，讓一個(gè)個(gè)北京人已經(jīng)深受其害，霧霾多發(fā)是否和全球氣候變暖有關(guān)？答案是肯定的，全球氣候變暖一定程度上加劇了霧霾多發(fā)。霧霾的危害或在10年至20年集中顯現(xiàn)，全球變暖所帶來(lái)的暖冬使得冷空氣活動(dòng)減弱，不利于污染物的擴(kuò)散，使得霧霾不斷來(lái)襲，污染著大氣，氣象條件是“幫兇”，大氣污染才是“主兇”。立即行動(dòng)起來(lái)，減少二氧化碳的大量排放，讓灰蒙的天空早日重現(xiàn)清澈的藍(lán)天。各地都開(kāi)始實(shí)施預(yù)防的措施，實(shí)行單雙號(hào)限制，燃煤改為天然氣或熱力來(lái)減少煤的排放量，加油站油氣回收治理，公交車(chē)和出租車(chē)實(shí)行電力運(yùn)行，在一定程度上減少了二氧化碳的排放，但這需要大家每一個(gè)人共同堅(jiān)持，共同保護(hù)這一片藍(lán)天。當(dāng)大街上每個(gè)人都戴著口罩，周?chē)黄颐擅傻奶炜諘r(shí)，你應(yīng)該行動(dòng)起來(lái)，從身邊的每件節(jié)能減排的小事做起，地球不是我們一個(gè)人的，是每個(gè)人的，我們都應(yīng)讓我們的地球家園變成藍(lán)色港灣，讓我們都行動(dòng)起來(lái)！
