气候改变的影响英文_气候变化对人有什么影响英语

气候变暖,使得海平面上升,沿海城市和低地被淹没,造成大量难民,陆地上冰川融化,近期导致地表水增加,洪涝危害加大,远期导致淡水减少,人类面临严重的水短缺危机。

气候变暖,会导致世界各地降水状况和干湿状况的变化,中纬度地区的耕地会退化成草原,粮食产量减少,高纬度地区会因变暖降水量会增加,适合于温带作物的生长,有利于粮食的增产。

解决方案

优化能源结构、提高能效、调整产业结构、研发应用低碳技术、转变观念增强低碳消费意识等被认为是全球应对气候变化的重要途径。

可再生能源

相比传统的肮脏的化石能源,可再生能源有着许多显而易见的好处:不用担心燃料枯竭的问题,发电过程中不产生温室气体和其它污染物,更有利于实现分布式的供电。各种研究也证明,中国有发展可再生能源的巨大潜力。

风能

风能是世界发展最快的能源,也是相对简单的技术能源。在一道高耸的巨塔和转动的扇叶背后,藏着轻量物料、空气动力和电脑操控系统之间的一套复杂相互作用。电力从旋转轮,通过变速齿轮箱,然后送到发电机,虽然有些涡轮机不用齿轮箱也可直接推动。

The Sixth Extinction By Niles Eldredge

About 30,000 species go extinct annually.

大约每年有30000种物种走向灭绝。

There is little dou left in the minds of professional biologists that Earth is

currently faced with a mounting loss of species that threatens to rival the five

great mass extinctions of the geological past.

在生物学专家心中都有一个小小的疑问,地球是否在面临着可能媲美过去五大物种灭绝的另

一次不断增加的物种灭绝。

As long ago as 1993, Harvard biologist E.O. Wilson estimated that Earth is

currently losing something on the order of 30,000 species per year -- which

breaks down to the even more daunting statistic of some three species per hour.

早在1993年,哈佛一名生物学家,E.O. Wilson就预测地球物种正在以每年30000种的速度消

失, 而这种令人心悸的预测则被更为恐怖的每小时3种的统计结果结束了.

Some biologists he begun to feel that this biodiversity crisis -- this "Sixth

Extinction" -- is even more severe, and more imminent, than Wilson had supposed.

The previous mass extinctions were due to natural causes.

一些生物学家已经开始察觉到生物多样性的危机了. Wilson预测说这次的第六次物种灭绝,

比以往五次更为严重,更为紧迫。前几次大量物种灭绝的发生,只是因为自然原因。

Extinction in the past

过去的几次大量物种灭绝

The major global biotic turnovers were all caused by physical events that lay

outside the normal climatic and other physical disturbances which species, and

entire ecosystems, experience and survive. What caused them?

过去的几次生物界翻天覆地的变化,原因都不外乎正常的天气还有其他的物理因素干扰这些

物理因素,而整个生态系统都安然度过了。这些都是怎样发生的呢?

* First major extinction (c. 440 mya): Climate change (relatively severe and

sudden global cooling) seems to he been at work at the first of these-the end

-Ordovician mass extinction that caused such pronounced change in marine life

(little or no life existed on land at that time). 25% of families lost (a family

may consist of a few to thousands of species).

第一次大量物种灭绝(c.440 mya):较为严重的突然全球变冷似乎先发生,然后就有了

引起海洋物种显著变化的后奥陶纪的大量物种灭绝(当时很少或者根本没有生物在大路上生

存),大约25%的物种科目消失了(一个物种科目可能含有几十到上千的物种)。

* Second major extinction (c. 370 mya): The next such event, near the end of

the Devonian Period, may or may not he been the result of global climate

change. 19% of families lost.

第二次大量物种灭绝(c. 370 mya):第二次类似的发生在大概泥盆纪结束的时候

,尚未清楚是否由于全球气候的变化。这次有19%的物种科目消失了。

* Third major Extinction (c. 245 mya): Scenarios explaining what hened at

the greatest mass extinction event of them all (so far, at least!) at the end of

the Permian Period he been complex amalgams of climate change perhaps rooted

in plate tectonics movements. Very recently, however, evidence suggests that a

bolide impact similar to the end-Cretaceous event may he been the cause. 54%

of families lost.

第三次大量物种灭绝(c. 245 mya):地质构造论中二迭纪发生的大范围地壳运动和气

候的复杂多变可以解释这次起码到现在为止是最大规模的大量物种灭绝。但在最近,又有证

据说类似于后白垩纪的流星可能是这次物种灭绝的主要原因。这次54%的物种科目被灭

绝了。

* Fourth major extinction (c. 210 mya): The event at the end of the Triassic

Period, shortly after dinosaurs and mammals had first evolved, also remains

difficult to pin down in terms of precise causes. 23% of families lost.

第四次大量物种灭绝(c.210 mya):这次大量物种灭绝发生在发生在三叠纪后期,在进

化出恐龙和哺乳动物之后不久。这次物种灭绝很难精确确定出原因。23%的物种科目消失了

* Fifth major extinction (c. 65 mya): Most famous, perhaps, was the most

recent of these events at the end-Cretaceous. It wiped out the remaining

terrestrial dinosaurs and marine ammonites, as well as many other species across

the phylogenetic spectrum, in all habitats sampled from the fossil record.

Consensus has emerged in the past decade that this event was caused by one

(possibly multiple) collisions between Earth and an extraterrestrial bolide

(probably cometary). Some geologists, however, point to the great volcanic event

that produced the Deccan traps of India as part of the chain of physical events

that disrupted ecosystems so severely that many species on land and sea rapidly

succumbed to extinction. 17% of families lost.

第五次大量物种灭绝(c. 65 mya):物种灭绝中最为著名的可能莫过于距离现在最近的

在白垩纪末发生的第五次物种灭绝. 根据对化石的研究发现,在这次物种灭绝中,陆地恐龙和

鹦鹉螺都完全消失. 有着同样命运的还有许多物种谱中的生物. 在过去十年中,大家都认为

这次物种灭绝的原因在于一次(也有可能是多次)地球与宇宙流星(很有可能是彗星)的相撞.

但一些地质学家持不同意见。他们把原因归结于产生了印度德干traps(陷阱?)的火山运

动而造成的生态系统的剧烈变动,最终使陆地上和海里的许多生物迅速走向灭绝。

The current mass extinction is caused by humans.

现在我们面临的大量物种灭绝是人为因素造成的。

How is the Sixth Extinction different from previous events?

第六次大量物种灭绝与之前有什么不同呢?

At first glance, the physically caused extinction events of the past might seem

to he little or nothing to tell us about the current Sixth Extinction, which

is a patently human-caused event. For there is little dou that humans are the

direct cause of ecosystem stress and species destruction in the modern world

through such activities as:

初步来看,过去五次大量物种灭绝对现在第六次认为造成的物种灭绝没有任何可借鉴意义,

因为毫无疑问人类造成了如下几种情况,给生态系统造成了很大压力,给物种带来了灭绝:

* transformation of the landscape

地貌的改变

* overexploitation of species

物种的过度开发

* pollution

污染

* the introduction of alien species

带来了外来物种

And because Homo sapiens is clearly a species of animal (however behiorally

and ecologically peculiar an animal), the Sixth Extinction would seem to be the

first recorded global extinction event that has a biotic, rather than a

physical, cause.

同样由于智人很明显是动物的一员(虽然行为和外貌上不很像动物),第六次物种灭绝似乎

是有史以来第一次由生物而不是物理环境变化引起的。

We are bringing about massive changes in the environment.

我们给环境带来了剧烈的变化。

Yet, upon further reflection, human impact on the planet is a direct analogue of

the Cretaceous cometary collision. Sixty-five million years ago that

extraterrestrial impact -- through its sheer explosive power, followed

immediately by its injections of so much debris into the upper reaches of the

atmosphere that global temperatures plummeted and, most critically,

photosynthesis was severely inhibited -- wreaked hoc on the living systems of

Earth. That is precisely what human beings are doing to the planet right now:

humans are causing vast physical changes on the planet.

Humans began disrupting the environment as soon as they eared on Earth.

然而进一步的说,人类对于地球的影响,完全相当于白垩纪的彗星撞击。彗星带来了爆炸性

的力量,紧接着把碎片带到大气上层,引起了全球气候降低,还有最重要的,极大地降低了

光合作用,就像是对地球生态系统的愤怒轰炸一样。这完全和现在人类正在对这颗行星做的

一样:人类正在给这颗行星的物理环境带来巨大的改变,而这种改变,自从人类出现便已经

开始了。

What is the Sixth Extinction?

什么是第六次大量物种灭绝?

We can divide the Sixth Extinction into two discrete phases:

我们可以把第六次大量物种灭绝分为两段

* Phase One began when the first modern humans began to disperse to

different parts of the world about 100,000 years ago.

第一阶段开始于100,000年前现代人类分散到世界各地

* Phase Two began about 10,000 years ago when humans turned to agriculture.

第二阶段开始与10,000年前人类开始了农业劳动

气候变化对人类的危害有

(图像:快门)“KDSPs”现在已经超出官方:温室气体,如二氧化碳,对公共健康和构成威胁,根据对过去九年发表的275项科学研究的详尽回顾,

的研究人员做了这份报告,调查环境保护署(EPA)2009年的危害发现是否仍然有效,该发现发现温室气体对人类健康构成威胁。新的研究表明,现在有更多的证据表明,温室气体正在危害人类健康和。调查还发现了另外四个领域,在原始报告中没有列出,其中温室气体威胁着人们。

“质疑这一危害发现完全没有科学依据,”回顾首席研究员菲利普·达菲,福尔茅斯伍兹霍尔研究中心的总裁和执行主任,马萨诸塞州,告诉现场科学危害的理由比以往任何时候都要强烈。”[6气候变化的意外影响]

危害的发现是什么“最初的危害发现是在很长一段时间内形成的。它始于马萨诸塞州和其他州在布什总统执政期间起诉环保局,要求环保局监管温室气体排放。2007年,最高法院裁定,美国环保署不仅有权根据《清洁空气法》对温室气体进行监管,而且如果发现这些污染物危害人类,也不能拒绝监管。

“最高法院说,如果你确定温室气体是危险的,那么你必须对它们进行监管,”达菲他说但是,当然,最高法院本身不会说温室气体是否危险。这是一个科学的过程,不是合法的。因此,美国环保署对温室气体的危险性和非危险性进行了科学评估。

在2009年12月,美国环保署发布了这份报告,报告发现温室气体确实通过引起气候变化危害人类健康和。达菲说,巴拉克(Barack Obama) *** 利用这一发现实施了新的法规,如清洁能源和更严格的汽车和轻型卡车行驶里程标准,达菲说,特朗普 *** 内外的人士都讨论了推翻或重审这一濒危发现的问题。针对这些说法,达菲和他的同事们决定看看自从危害发现出来以来发表的科学研究,看看这门科学是加强了还是削弱了危害的理由。

这门科学所显示的

这篇新的评论将这些发现分为不同的类别:公共卫生,空气质量、农业、森林、水、海平面上升、基础设施和野生动物。这四个新类别包括海洋酸化、国家安全、经济福祉和暴力。以下是对其中几个城市的更深入研究。研究人员发现,美国200多个城市的

公共卫生概况

人群因未来气候变暖而过早死亡的风险增加。酷热与睡眠不足、肾结石、低出生体重、暴力和自杀有关。接触臭氧和其他空气污染物,包括森林火灾产生的烟雾,可能对人体健康有害。气候变化加剧的极端天气可能导致身体创伤、疾病爆发、医疗服务中断和精神健康问题。气温升高和二氧化碳水平也会增加花粉季节的长度,这会影响过敏的人。某些作物预计会产生更少的养分。人口流离失所和武装冲突也会扩大对人类健康的风险。[照片显示加州野火的恐怖场景]

山上积雪较少,西部和西南部可能会经历更多的干旱。减少积雪会导致河流流量减少,其中濒临灭绝的珍稀濒危物种,如鲑鱼和狼獾。气候变化预计还会因为营养盐的负荷(如肥料或动物粪便)而侵蚀美国的水质,特别是在中西部和东北部。

海平面上升

海平面升高将增加沿海社区、经济和基础设施的风险,主要是因为洪水、侵蚀和极端。这些影响可能会通过“气候绅士化”导致流离失所,在“气候绅士化”中,居住在较高海拔地区的人拥有较高价格的房产。主要港口城市之间的货物流动也可能受到影响,造成经济混乱。海平面上升也可能扰乱美国军队,以及灾难和人道主义救援工作。“KDSPE”国家安全“KDSPE”“KDSPE”“美国的现有安全性很可能需要随着地球变暖而改变。例如,在北极地区,减少的海冰将为中国更多的贸易路线和俄罗斯的石油和天然气开扫清道路,可能导致这些国家和美国之间的紧张关系,研究人员写道,

的经济福祉

预计在75年内增加1.8华氏度(1摄氏度)美国国内生产总值(GDP)永久性下降约3%。如果温室效应被限制在2.7华氏度(1.5摄氏度),美国国内生产总值预计将比工业化前水平高出3.6华氏度(2摄氏度)高出约4%。研究人员发现,较贫穷国家的经济因气候变化而承受的经济负担大约是较富裕国家的五倍,

暴力和不稳定

气温上升和降雨量增加会加剧暴力和不稳定。在美国,较高的气温与较高的家庭暴力、 *** 、袭击和谋杀率有关。越来越多的证据表明,气候变暖也可能增加包括自杀在内的自残风险。

的外卖信息

这些发现“突出了科学和政策之间的这种对比,”达菲说纽约哥伦比亚大学拉蒙特-多尔蒂地球观测站的气候科学家杰森·斯默顿说:“科学证据是朝着一个方向发展的,而政策则是朝着完全相反的方向发展的。”,他对《生活科学》杂志说:“如果你一直关注的话,2009年的危害发现是很有道理的,而且从那以后它才变得更强。”这基本上是支持事实的大量证据。人们已经非常清楚地将我们造成的气候变化与下游的影响联系起来。

这篇评论也清楚地表明,气候变化将影响所有人,而不仅仅是遥远地区的人。

这样的报告都指出,我们每个人都将以不同的方式受到气候变化的影响,“它会在我们所有的后院,”斯默登说这并不是一件遥远的事情。

这篇评论昨天(12月13日)发表在《科学》杂志的网络版上。

全球气候变化对人类活动的影响是什么?

气候变化对人类的危害有

A、环境恶化和气候灾害频发

B、降水量变化和水短缺

C、生态系统破坏和物种灭绝

D、冰川减少和海平面上升

正确答案:ABCD

人口增长的原因和后果英语作文

全球气候变化对人类活动的影响是:

1、气候变暖,使得海平面上升,沿海城市和低地被淹没,造成大量难民,陆地上冰川融化,近期导致地表水增加,洪涝危害加大,远期导致淡水减少,人类面临严重的水短缺危机。

2、气候变暖,会导致世界各地降水状况和干湿状况的变化,中纬度地区的耕地会退化成草原,粮食产量减少,高纬度地区会因变暖降水量会增加,适合于温带作物的生长,有利于粮食的增产。

3、全球气温升高的同时,海水温度也随之增加,这将使海水膨胀,导致海平面升高.再加上由于极地增暖剧烈,当大气中CO2浓度加倍后会造成极冰融化而冰界向极地萎缩,融化的水量会造成海平面抬升。

全球气候变化应对措施:

1、减少二氧化碳排放量。为此注意以下几方面:

(1)提高能源利用技术和能源利用效率,进而减少煤、石油、天然气的使用量,减少二氧化碳的排放。

(2)用新能源,如:太阳能、风能、地热能、海洋能、核能、氢能等;也可以提高常规能源中水能的利用比重,间接减少二氧化碳的排放量。

(3)加强国际间的合作,取长补短,共享先进经验。

2、植树造林,使森林在吸收、固定二氧化碳方面发挥更大的作用。

In the 10s, it was considered to account for the population at that time had lived on earth for 75% of the total population. The widely quoted statistics are too affected by the impact of the 20th century population explosion - the proportion of it is incredibly high. To get a more accurate result, we must determine when modern humans from the beginning, the birth rate is the number, and the history of how many people lived in the end. Generally believe that modern man is in the 50,000 years ago. We can imagine, does not limit the population was born, and life expectancy is very short, which resulted in a young population and higher fertility rates - every mother's health at around six to eight children. To the Middle Ages, the birth rate began to decline long. The record shows that since the 18th century, when the industrialized countries, the birth rate continues to decline. U.S. demographers Carl - Hao Po (CarlHaub) that, before the advent of agriculture, hunting in the way, the world's population is only about 5 million to 10 million. Light of the message, to the 1st century AD, according to the Roman, Chinese and Mediterranean off the census, the world's population has grown to 300 million. Application of this population a higher birth rate, we can estimate that so far a total of life on Earth over roximately 106 billion people. We now he 6.1 billion people, accounting for life on Earth has had a total population of 5.7%. In 1900, only 16 million people around the world, but developing countries rapid population growth led to the proliferation of the world's population, so we had a population proportion of the population of the Earth on the rise.在20世纪70年代,有人认为,当时的人口要占地球上曾经生活过的总人口的75%。

这一被广泛引用的统计结果过于受20世纪人 *** 炸的影响——比例实在是高得令人难以置信。

要想得到一个比较精确的结果,我们必须确定现代人类是从何时开始的,出生率是多少,以及历史上到底生活过多少人。

普遍认为,现代人是在5万年前出现的。

我们可以设想,当时是不会限制人口出生的,且人的寿命都很短,这就导致一个年轻的人口结构和较高的生育率——每个母亲大约会生6到8个孩子。

到了中世纪,出生率开始长时间地下降。

18世纪以后的记录表明,当时的工业化国家,出生率在持续下降。

美国人口学者卡尔-郝伯(CarlHaub)认为,在农业出现以前,在以为生的方式下,全世界的人口大约只有500万到1000万。

科技之光消息,到了公元1世纪,根据当时罗马、中国和地中海地区的断断续续的人口普查,世界人口已增长至3亿。

对这个人口应用一个较高的出生率,就可以估算出,迄今为止地球上总共生活过大约1060亿人。

我们现在有61亿人,占地球上曾经生活过的总人口的5.7%。

在1900年,全世界只有16亿人,但是发展中国家人口的快速增长导致世界人口的激增,所以我们现有人口占地球曾有人口的比例在上升。

The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleoecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one m illion B. C., followed the innovations of tool making and tool using. But when the new power from the use of tools has been exploited, the rate of world population growth fell and became almost stable. The next rapid jump in population started perhaps 10,000 years ago, when mankind began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated. These o episodes suggest that the third great change, the present rapid growth, which began in the West beeen 250 and 350 years ago, may also slow down when, or if, technology begins to yield fewer innovations. Of course, the current knowledge revolution may continue without foreseeable end. Either way - contrary to popular belief in constant geometric growth - population can be expected in the long run to adjust to productivity. And when one takes this view, population growth is seen to represent economic progress and human triumph rather than social failure.

Progress in science and the improvement of living conditions he led m the rapidgrowth of the world population. Modern medical science, for example, has made it possible for babies to grow up healthily and for people to live longer.With improved living conditions, particularly in the countryside, people tend to he larger families. As a resuit, the world population has increased so rapidly that it has now exceeded 5 billion. But the overgrowth of population presents a threat to the existence of human society. A large population demands a great deal of food supply and shelter space. However,the limited productivity and scarce natural resources can hardly meet the needs of the ever-Increasing population. Thus in the long run, the overgrowth of the world population will only harm mankind.4ia英语作文网To guarantee the steady development of human society, mankind must realize the consequences resulting from a fast population growth and the importance of carrying out a family planning programme.
