全球气候变暖指的是在一段时间中，地球大气和海洋温度上升的现象。

近100年来，全球平均气温经历了：冷——暖——冷——暖四次波动，总的看气温为长升趋势。进入上世纪八十年代后，全球气温明显上升。

为什么全球气候会变暖呢？

全球大气层和地表这一系统就如同一个巨大的“玻璃温室”，使地表始终维持着一定的温度，产生了适于人类和其它生物生存的环境。在这一系统中，大气既能让太阳辐射透过而达到地面，同时又能阻止地面辐射的散失，我们把大气对地面的这种保护作用称为大气的温室效应，造成温室效应的气体称为“温室气体”，它们可以让太阳短波辐射自由通过，同时又能吸引地表发出的长波辐射。这些气体有二氧化碳、甲烷、氯氟化碳、臭氧、氮的氧化物和水蒸汽等，其中最主要的是二氧化碳。近百年来，全球的气候正在逐渐变暖，与此同时，大气中的温室气体的含量也在急剧增加。许多科学家都认为，温室气体的大量排放所造成温室效应的加剧是全球变暖的根本原因。而温室气体的大量排放又与日益发达的现代工业有着直接的关系。因此，倡导节能环保，开拓新兴工业产业已成为全球各国的共识。

不仅工业企业生产会排放大量的温室气体，随着人们生活水平的提高，我们每个人的日常生活也会造成一定量的温室气体的排放。如用电、用水、用纸……换言之，全球气候变暖与我们每个人都有，我们要科学地生活、工作、学习。让我们的一言一行都绿色环保。

全球气候变暖的结果是灾难性的：冰川消融，海平面升高，引起海岸滩涂湿地，红树林和珊瑚礁等生态群丧失，海岸侵蚀，海水入侵沿海地下淡水层，沿海土地盐渍化等。从而造成海岸、河口、海湾自然生态环境失衡，给海岸带的生态环境带来了极大的灾难。不仅如此，还会将水域面积增大，遭受风暴影响的程度和性加大，水库大坝寿命缩短。气温升高可能会使南极半岛和北冰洋的冰雪融化，北极熊和海象会渐渐灭绝。最终造类赖以生存的地球成为不适宜人居住的星球

急需一篇关于全球变暖的作文

科技小论文

——警惕全球变暖

最近这几年，大家觉得天气一下子就变热了，原本凉爽的秋天现在几乎要到10月下旬才开始，8月份最热的天居然达到了40度以上。这是为什么呢？原来，是人类自己惹的祸。

随着人类高科技发展进程越来越快，科学随之产生的副作用逐渐体现出来，全球变暖就是一个例子。天气炎热，在酷暑里泡空调成为了一项新的“业余爱好”，但人们可曾想过，空调会带来什么负面影响呢？当然是肯定的，空调排放的气体中含有大量的甲烷，输送到外面，甲烷也是导致全球变暖的气体。同时，空调还会浪费掉许多电，所以要尽量避免用空调，适当即可。

而另一个原因就是：二氧化碳！汽车尾气与工厂废气中含有大量二氧化碳，而二氧化碳最可能导致温室效应（即全球变暖）现在汽车逐渐增多，据有关方面统计，到21世纪，汽车在全世界已有7亿辆，大量的尾气影响着我们，咳嗽，喉咙发炎……最重要的是全球变暖。有人统计，美国人均二氧化碳排放量已达到了20吨一年！每年的二氧化碳排放量人均排放量也有2.51吨一年！我们周围的环境在恶劣地变化。

更重要的原因就是：森林锐减，水资源破坏，生态链被破坏，大量土地贫瘠，水污染，据统计全世界10%的河水被污染，新鲜的淡水供应成了问题，同时由于矿物质被大量使用，燃烧出的CO2气体导致了大气污染，同时臭氧层被破环，南北极出现臭氧层洞，加剧了环境的恶化。这样恶性循环的话，最终会导致人们的生活被影响。

这样一来的悲剧是什么呢？当然是显而易见了！天气加热，海平面上涨，南川融化，海滨城市，岛国被淹。这一切，都影响了人类的生存，实验证明，以后300年，海平面将上涨半米多，这还是最乐观的数据。再过7年，全球变暖将会无可逆转地持续。更可怕的是，由于融化，降雨量加强，大量淡水汇入北大西洋，破坏了墨西哥暖流，一旦墨西哥暖流被切断后，欧洲西北部温度将会下降5—8度之多，从而造成的影响，很可能引发新的冰河时期！想必大家一定看过《后天》这部电影，剧中的情景正是几百年后对我们地球的一个真实写照：龙卷风，冰层断裂，温度急剧下降，冰风暴，冻雨，，洪水，海啸……这并不是疯狂的幻想，如果人类不停止毁坏环境的话，这将成为现实！全球变暖不仅仅是天气变热，更会牵连出许多负面影响！

为了拯救地球，我们应该尽量做到：不开空调，使用回收环保纸张，舍弃肉类（牛排）食品（牛消化中含有，如果你转为素食主义者，每年二氧化碳的排放量将减少1.5吨！）不用塑料袋，乘公交车……生活中的点点滴滴。其实环保并不难，只要你支持环保，就是你给这个星球的礼物，不需要太多言辞，只要每个人都行动起来，就会是一股强大的力量！如今，日本，英国，美国等纷纷行动起来，我们虽然也采取了行动，但，对于一个有13亿人口的泱泱大国，这一点，还是不够的。

所以，警惕全球变暖，是全人类为了挽救地球的方法，有人也许会说：我们不是可以移居到别的星球上去吗？虽是肯定的，但那又能容纳多少人呢？有人说：治理温室效应的资金太大了，对金融来说是天价。但，如果一直拖延，最终的结果，是我们的地球面目全非，别说金融，就连自己的生命也难保啊！所以环境保护不应只停留在口头上，而要真正付之与行动了。

(可能字数多了点儿吧！)

高二作文 “全球暖化” 不少于120个词

With the dlopment of economy，more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases，which is considered to be one of the greatest causes of global warming. It has harmful effects，causing the sea ll to rise and many natural disasters to strike.

So we must take effective measures to se our planet. First，we should use more clean energy and less coal and oil. Second，we should go to work on foot or by bus instead of driving a car if sible. Third， we should plant more trees， because plants can turn CO2 into oxygen. More importantly， we should form the habit of sing energy in our daily life.

To stop global warming we should make immediate and continual efforts. We hope the situation will soon change. Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right. Do it right now.
