argument47
   Scientists studying historical weather patterns have discovered that in the mid-sixth century, Earth suddenly became significantly cooler. Although few historical records survive from that time, some accounts found both in Asia and Europe mention a dimming of the sun and extremely cold temperatures. Either a huge volcanic eruption or a large meteorite colliding with Earth could have created a large dust cloud throughout Earth's atmosphere that would have been capable of blocking enough sunlight to lower global temperatures significantly. A large meteorite collision, however, would probably create a sudden bright flash of light, and no extant historical records of the time mention such a flash. Some surviving Asian historical records of the time, however, mention a loud boom that would be consistent with a volcanic eruption. Therefore, the cooling was probably caused by a volcanic eruption.

1.Maybe the dust cloud is not the reason for that earth became cooler. Other records in other continents might be found.
2.Record about the sudden bright flash of light was absent cannot explain a collision hadn’t happened.
3.A loud boom might be caused by other thing, but the eruption of volcano.

      Given these facts that a dimming of the sun and extremely cold temperature in Asia and Europe, no record about collision and a historical records mentioned a loud boom, the argument conclude that the cooler of the earth happened in the mid-sixth century, which was caused by a volcanic eruption. The reasoning of the argument, however, is biased due to inadequate and partial evidences to justify the conclusion.

     To begin with, maybe a large dust cloud is not the reason for the earth became cooler. As mentioned in the argument, few historical records have been found, so the large dust cloud which can be caused by a huge volcanic eruption or a large meteorite colliding with Earth, just is the speculation of the arguer. Other possibilities cannot be ruled out for global temperature lowered sharply, and it is possible that a planet in the universe came into the solar system and produce a force towards the earth-sun system that just effect the earth go round the sun as before in the mid-six century.

      Moreover, even assuming that it is a large dust cloud throughout earth’s atmosphere block enough sunlight, in turn cooler the earth temperature significantly, the possibility of a large meteorite colliding with Earth led to the dust cannot be eliminated, only for the reason that records about the sudden bright flash of light resulted from the collision wasn’t found. During that time, no person was at present, or these people experienced the collision died for the calamity, or some records exist but haven’t been found yet. All of these are possible, so the arguer cannot persuade me to agree that it is a volcanic eruption but a meteorite make the dust cloud.

     In addition, according to the Asian historical records of the time, a loud boom was mentioned.Earthquake or tsunami can also produce a loud boom, so the collusion of the argument that the dust cloud is caused by a collision is farfetched, let alone the lower temperature of the earth.

   To sum up, there are also other factors giving rise to the cooling of the temperature, such as earthquakes, tsunami and so on. As there are no exact historical records from which we can learn the true reality, we should not give a conclusion hastily. Instead, we should stick to a strict scientific attitude and try to find the convincing evidence before drawing a conclusion.

每一点可以更展开！以增加字数！
有些语法问题，我改了第一段！
Given these facts that (of) a dimming of the sun and extremely cold temperature in Asia and Europe, no record about collision and a historical records mentioned a loud boom, the argument (arguer)conclude(concludes) that the cooler of the earth happened (删去) in the mid-sixth century, which(删去) was caused by a volcanic eruption. The reasoning of the argument, however, is biased due to inadequate and partial evidences(evience 不可数） to justify the conclusion.

Given these facts that a dimming of the sun and extremely cold temperature in Asia and Europe, no record about collision and a historical records mentioned a loud boom, the argument conclude that the cooler of the earth happened in the mid-sixth century, which was caused by a volcanic eruption. The reasoning of the argument, however, is biased due to inadequate and partial evidences to justify the conclusion.前面的连续列举语法上没有问题么？我觉得好像一般都把and放在最后的。去噢不是很确定。

      Moreover, even assuming that it is a large dust cloud throughout earth’s atmosphere block enough sunlight, in turn cooler the earth temperature significantly, the possibility of a large meteorite colliding with Earth led to the dust cannot be eliminated, only for the reason that records about the sudden bright flash of light resulted from the collision wasn’t found.

展开得不够充分，语言还没有成形，加油

有一个逻辑错误前提：
There is not enough convincing evidence to show that the earth climate had been ddrastically chaged.
