全球变暖英语作文【篇一】
At present, the gravity of the situation of global warming. This is not only related to atmospheric pollution, there is a certain relationship with the sun.
Solar system is like a boundless cobwebs, but the sun is in the middle position, the earth will spread around the sun (from a distance is very close to the earth and the sun is, far, far away, but the actual distance of unimaginable). The earth moves around the sun, like a big ball on a large online, with a small steel ball on quality be sunken place big iron ball pressure, then you will find that the quality of small iron turn the club around the big iron ball, far from the big iron ball, and turned slowly, later you will find that the small ball go faster and faster, is getting closer and closer to the big iron ball, will eventually collided with the big iron ball.
According to the findings, you may have found the cause of global warming. The sun is like a big ball is located in the center of network, motionless, and the earth like a small ball moves around the sun. Because the distance between the sun and the earth are too big, so a long time to collide with the sun. And now the earth slowly close to the sun (said to be close to, in fact is a long way) so say, the cause of global warming, does not rule out the ah.
This is just a guess. I think, however, do not rule out this reason, who knows the earth what will happen in the future.
Looking forward to...
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。
期待……
全球变暖英语作文【篇二】
After investigation, we found that caused the main reason for the increase of greenhouse gases is human activity. Carbon dioxide, for example, before the human society to realize industrialization in the early 19th century, the concentration of carbon dioxide in the atmosphere to 270 parts per million, and in 1988 to rise to 350 PPM. Atmospheric co2 concentration increased there are two main reasons: first, the dramatic increase in population and the development of industrialization, human society, consumption of fossil fuels has increased dramatically, combustion produces a large amount of carbon dioxide into the atmosphere, increase the concentration of carbon dioxide in the atmosphere: second forest reduces the amount of carbon dioxide absorbed by plants use, a speed reduction in carbon dioxide is consumed, also leading to higher concentration of carbon dioxide in the atmosphere. Greenhouse gases than carbon dioxide, such as methane, CFCS (freon), nitrogen oxide and so on also need to increase a different level.
Although there are many uncertainties, it is clear that global warming on climate, rainfall, and the influence of sea level and the resulting impact on human settlements and the ecosystem is extremely complex, must be given the attention they deserve. Think this kind of influence is irrelevant in the long run view is irresponsible.
The main cause of global warming, the atmosphere is destroyed, serious pollution and greenhouse effect caused by global warming could affect global warming will bring to the earth and human complex potential impact, both positive and there are also negative. Such as temperature height, deputy polar regions may be more suitable for human habitation, under appropriate conditions, higher co2 concentration can promote the photosynthesis, which plants have a higher rate of carbon sequestration, lead to the increase of plant growth, namely the stimulation effect of carbon dioxide, which is the positive impact of global warming. But compared with the positive impact, the negative impact of global warming on human activity will be more vast and far-reaching.
经过调查，我们发现引起温室气体增加的主要原因是人类活动。以二氧化碳为例，在人类社会实现工业化以前的19世纪初，大气中二氧化碳的浓度为270ppm，而到了1988年以上升到350ppm。大气中二氧化碳浓度增加的原因主要有两个：首先，人口的剧增和工业化的发展，人类社会消耗的化石燃料急剧增加，燃烧产生大量二氧化碳进入大气，使大气中的二氧化碳浓度增加：其次森林毁坏使得被植物吸收利用的二氧化碳的量减少，造成二氧化碳被消耗的速度降低，同样造成大气中二氧化碳浓度升高。二氧化碳以外的.温室气体，如甲烷、氯氟烃(氟里昂)、氧化氮等也不同程度得增加着。
尽管存在着许多的不确定性，但显而易见的是，全球气候变暖对气候带、降水量以及海平面的影响以及由此导致的对人类居住地及生态系统的影响是极其复杂的，必须给以应有的重视。认为这种影响从长远来看是无关紧要的看法是不负责任的。
全球气候变暖的主要原因：大气层遭到破坏，严重的污染以及温室效应全球变暖可能造成的影响全球变暖将给地球和人类带来复杂的潜在的影响，既有正面的，也有负面的。例如随着温度的身高，副极地地区也许将更适合人类居住：在适当的条件下，较高的二氧化碳浓度能够促进光合作用，从而是植物具有更高的固碳速率，导致植物生长的增加，即二氧化碳的增产效应，这是全球变暖的正面影响。但是与正面影响相比，全球变暖对人类活动的负面影响将更为巨大和深远。
