全球變暖英語作文【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，全球變暖事態(tài)嚴重。這不僅跟大氣污染有關(guān)，很有可能跟太陽運動存在著某種關(guān)系。
太陽系就像一張無邊無際的蜘蛛網(wǎng)，而太陽就位于中間位置，地球就散布在太陽旁邊(從遠處看地球和太陽是很近，但實際很遠很遠，遠的難以想象)。地球是圍繞太陽轉(zhuǎn)的，好比把一個大鐵球放在一張大網(wǎng)上，在拿一個質(zhì)量小的鐵球放在被大鐵球壓凹的地方，這時你會發(fā)現(xiàn)，質(zhì)量小的鐵球會圍繞大鐵球轉(zhuǎn)，先是離大鐵球遠，而且轉(zhuǎn)的速度很慢，過一會你會發(fā)現(xiàn)小鐵球越轉(zhuǎn)越快，離大鐵球越來越近，最終會跟大鐵球相撞。
根據(jù)這個發(fā)現(xiàn)，你也許會知道全球變暖的原因了。太陽就像大鐵球位于網(wǎng)中心，一動不動，而地球就像小鐵球一樣圍繞太陽轉(zhuǎn)。因為太陽和地球距離相差太大，所以要很長時間才和太陽相撞。而且現(xiàn)在地球慢慢接近太陽(說是接近，其實還很遠吶)所以說啊，地球變暖的原因，也不排除這個啊。
這只是一種猜想。不過，我想也不排除這個原因，誰知道日后的地球會發(fā)生什么事吶。
期待……
全球變暖英語作文【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.
經(jīng)過調(diào)查，我們發(fā)現(xiàn)引起溫室氣體增加的主要原因是人類活動。以二氧化碳為例，在人類社會實現(xiàn)工業(yè)化以前的19世紀初，大氣中二氧化碳的濃度為270ppm，而到了1988年以上升到350ppm。大氣中二氧化碳濃度增加的原因主要有兩個：首先，人口的劇增和工業(yè)化的發(fā)展，人類社會消耗的化石燃料急劇增加，燃燒產(chǎn)生大量二氧化碳進入大氣，使大氣中的二氧化碳濃度增加：其次森林毀壞使得被植物吸收利用的二氧化碳的量減少，造成二氧化碳被消耗的速度降低，同樣造成大氣中二氧化碳濃度升高。二氧化碳以外的.溫室氣體，如甲烷、氯氟烴(氟里昂)、氧化氮等也不同程度得增加著。
盡管存在著許多的不確定性，但顯而易見的是，全球氣候變暖對氣候帶、降水量以及海平面的影響以及由此導致的對人類居住地及生態(tài)系統(tǒng)的影響是極其復雜的，必須給以應有的重視。認為這種影響從長遠來看是無關(guān)緊要的看法是不負責任的。
全球氣候變暖的主要原因：大氣層遭到破壞，嚴重的污染以及溫室效應全球變暖可能造成的影響全球變暖將給地球和人類帶來復雜的潛在的影響，既有正面的，也有負面的。例如隨著溫度的身高，副極地地區(qū)也許將更適合人類居住：在適當?shù)臈l件下，較高的二氧化碳濃度能夠促進光合作用，從而是植物具有更高的固碳速率，導致植物生長的增加，即二氧化碳的增產(chǎn)效應，這是全球變暖的正面影響。但是與正面影響相比，全球變暖對人類活動的負面影響將更為巨大和深遠。
