全球变暖作文 篇1

当全球气候变暖时，世界发生了巨变。

南极，冰雪融化，人类感觉将要处于冰水之中，这是人类自食其果。北极的霸主北极熊，也因全球变暖而逐渐走向灭绝。一直熊妈妈向小熊递来一把剪刀，熊宝宝好奇地问：“妈妈，用剪刀干什么呀？”妈妈以命令的语气回答：“快剪毛，再长这么厚的毛会被热死的！”小熊天真的望着妈妈：“我们住在冰天雪地里，怎么会热呢？这是我们的外衣，没有它会受冻的，不能剪！”熊妈妈的语气中带点悲伤和叹息：“现在全球变暖，在不适应，恐怕就走向灭亡了！”

全球变暖，北极熊无法找到食物，甚至食用小熊，这是被逼无奈呀！人类应当对自己的行为进行深刻的反省，可是，当全球变暖时，人类还无法意识到自己的错误！只知道冬天不再受寒风的折磨，温度上升了，寒冷已离去，只顾着眼前利益，可不知道以后将远离那洁白的雪，原本应在寒冬中开放的花。

当全球变暖时，希望人类早已意识这以后果。趁早弥补，阻止这一切的发生！

全球变暖作文 篇2

As more and more countries become industrialized,global environment has been inevitably changed.And we are just experiencing the altered climate.Human activity is affecting global climate.Many scientists have predicated that global temperature will continue to rise in the foreseeable future because greenhouse gas emission is still increasing.

Now there is a growing awareness that climate change is definitely not confined to a certain region or country.

However,it is a problem all countries are involved.Most people would agree that as the planet warms and the sea ice is melting,polar bears are vulnerable to lose habitat,even

threatening our home around the coastal areas.It is time we took measures to protect our environment.

There is no denying that industrial emissions have been the dominant influence on climate change for the past 50

years,overwhelming natural forces .To improve this situation, First of all, Ultimately, we,everyone on this blue planet are supposed to promote and carry out"low-carbon"lifestyle as an obligation.Secondly,carbon emission reduction must be put into implement,especially reducing fuel consumption and exhaust emissions,and it a wise choice for us to use renewable energy resources.Moreover,global climate summit are expected to play

a significant part in urging involved powers to Carry out the state strategy of sustainable development so that our environment can be back to normal gradually.

Greenhouse gas emission is but one of the many effects for the climate change.Another is excessive deforestation.And the Amazon tropic rain forest has seen man's greediness.Just imagine what would be like if our forest coverage rate were what it was 20 years ago?The answer is quite clear that global temperature would be lower and many species may not die out.Therefore,we must quit using disposable packaging and dishware and encourage of employment of

environmentally-friendly materials.Besides,people ought to develop an awareness of environmental protection and cherish forests resources.Of course supporting recycling is also a good alternative way.

In present case ,yet it could go a long way for us to recover our environment from climate change,we are obligated to

dedicate ourselves to go for a harmonious planet.In addition,we have every reason to try our best to protect our environment.I believe the new environment is in store with our efforts.

全球变暖作文 篇3

Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.

很多人都认为是人类活动导致了全球气温上升。他们说全球变暖会对我们的.环境造成可怕的后果，如干旱和洪水。

What should governments do to help prevent global warming? Give reasons for your suggestions.

政府该做什么来防止全球变暖呢？给出你建议的原因。

The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.

地球的温度正在迅速改变。导致很多气候变迁，如热浪、干旱和洪水。科学家认为这是人类活动污染了地球的大气层的结果。如果政府不采取行动来防止全球变暖的话，这可能会成为灾难。他们可以在三个方面上有所行动；支持研究，制订法律和保持公众知情。

Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.

首先，政府可以支持研究。例如，他们应该鼓励公司致力于汽车研发来减少污染。他们也应该支持来自风和水的电力替代能源，而不是来自石油和煤的电源。同时，他们应该主持会议来讨论温室气体排放的影响和可能解决问题的方案。

Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.

其次，他们应该制定法律限制公司发出的温室气体。私人公司应该因为遵循这些法律而得到奖励。他们也应该因为创造出污染而受到惩罚。

Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.

最后，每个人都是受到全球变暖的影响。因此，政府和个人在解决问题的过程中是很重要的。例如，他们应该鼓励家庭尽可能多的节省能源，尽可能多的使用更高效的灯泡或少用热水。他们也应该鼓励公众回收，因为这对每个人来说都是必须的。另一种节约能源的方法是公共交通系统。政府应该把钱花在公共交通使公众尽可能容易的节约能源。

In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.

总之，很明确的，各国政府可以做很多事情来防止全球变暖。他们应包括公司，支持科学家和鼓励个人保护地球。

全球变暖作文 篇4

目前，全球变暖事态严重。这不仅跟大气污染有关，很有可能跟太阳运动存在着某种关系。

太阳系就像一张无边无际的蜘蛛网，而太阳就位于中间位置，地球就散布在太阳旁边（从远处看地球和太阳是很近，但实际很远很远，远的难以想象）。地球是围绕太阳转的，好比把一个大铁球放在一张大网上，在拿一个质量小的铁球放在被大铁球压凹的地方，这时你会发现，质量小的铁球会围绕大铁球转，先是离大铁球远，而且转的速度很慢，过一会你会发现小铁球越转越快，离大铁球越来越近，最终会跟大铁球相撞。

根据这个发现，你也许会知道全球变暖的原因了。太阳就像大铁球位于网中心，一动不动，而地球就像小铁球一样围绕太阳转。因为太阳和地球距离相差太大，所以要很长时间才和太阳相撞。而且现在地球慢慢接近太阳（说是接近，其实还很远呐）所以说啊，地球变暖的原因，也不排除这个啊。

这只是一种猜想。不过，我想也不排除这个原因，谁知道日后的地球会发生什么事呐。

全球变暖作文 篇5

全球变暖现象是由温室气体产生的，最普通的温室气体是我们每天使用的化石燃料产生的二氧化碳。化石燃料主要为我们提供能量。化石燃料中主要是煤，其次是石油，再次是天然气。我们所有的`生产、生活行为都有可能导致产生温室气体，这就需要我们共同努力以维护人类的共同利益。

我们生活中有许多事都是我们可以做到的，比如说：我们要养成随手关灯的好习惯，及时关闭不需用的电器，包括电脑、电视机等家用电器。在喝水、做饭和搞卫生的时候，根据需要用水，不要浪费。我们生活中的物品尽可能反复使用。如果一件物品你已经不需要，而这个物品仍能使用，可以把它送给需要的人使用。去超市时带上自己的环保袋，减少使用商店提供的塑料袋。我们出行时尽可能步行或骑自行车，或者多选择公共汽车出行。同时，我们要多参加植树活动，因为树可以吸收多余的二氧化碳。

我觉得我们要从小事做起，从一点一滴做起，从我们每个人做起，为保护地球做出自己的贡献。我希望我们的地球在我们的努力下变得天更蓝、水更清、山更绿，让世界变得更美好！

全球变暖作文 篇6

最近，南极又一次出现了“西瓜雪”，这并不是第一次了。在去年，就发现了一次，同时，也是去年8月份的时候，阿尔卑斯山也是如此。而这是因为什么，罪魁祸首又是谁呢？全球变暖，这是最主要的问题。

全球变暖，这个问题一直都没有解决。我甚至要怀疑近两年冬天不下雪，也是因为全球变暖了！全球变暖，为藻类提供了很好的生长环境。而藻类，又可以使冰雪消融得更加的迅速。“雪衣藻”是加速冰川融化的幕后凶手，但是它们本身却没有伤害。它们格外的耐寒，“红色”是雪衣藻“熟了”的样子。所以，“西瓜雪”就是这么来的了！

从当前的数据来看，科学家在南极北端监测站测量的最高温度高达20。75℃！自1999年至2019年，南极的融雪现象一直很严重，融化面积高达总面积的19%，真的很可怕！

然而，海洋生物的数量也在锐减中，磷虾下降80%，企鹅下降了75%。虽说南京也仅仅只是一部分区域在气温下降，但雪衣藻会让南极的融雪增加，而融雪增加又加剧其成长，形成了恶性循环。“西瓜雪”会大大降低对阳光的反射，大面积地区将出现气候变暖。大大的威胁到了生态系统！可能也将会影响到我们的生存。然而，南极的气候暖化是一个格外缓慢的过程，同时，另一方面我们也要真正的警觉温度变化，真正的去关注南极的现状！

“西瓜雪”并不浪漫，南极洲是地球上仅剩的一块净土了。保护好环境，是我们每个人的责任。同样，为了控制住全球变暖，我们都要做出我们力所能及的事情。保护好地球上的最后一片净土，也是为了我们自己！
