The Little Ice Age was a period of unusually cold temperatures in many parts of the world that lasted from about the year 1350 until 1900 C.E. There were unusually harsh winters, and glaciers grew larger in many areas. Scientists have long wondered what caused the Little Ice Age. Several possible causes have been proposed.

First, the cooling may have been caused by disruption of ocean currents. Before the Little Ice Age, there was a period of unusually warm weather during which glaciers melted. These melted glaciers sent a large amount of cold freshwater into the Gulf Stream, a large ocean current that strongly affects Earth's climate. Some scientists believe that this freshwater was enough to temporarily disrupt the Gulf Stream current. Such a disruption could have caused the Little Ice Age.

Second, volcanic eruptions could have caused the Little Ice Age. When volcanoes erupt, they send dark clouds of dust and sulfur gas into the atmosphere. These clouds, which can spread over great areas, block some sunlight from reaching Earth's surface. This can decrease the global temperatures. Scientists know of several volcanic eruptions that took place during the Little Ice Age.

Third, substantial decreases in human populations may have contributed indirectly to the cooling of the climate. For a variety of reasons (disease, warfare, social disruption), the human population just before the Little Ice Age and during the early part of it was lower than it had been in a long time. Forest trees started growing on fields that were no longer used for agriculture. Since trees absorb carbon dioxide, a greenhouse gas, they decrease the greenhouse effect that keeps Earth warm. With more forest trees and less carbon dioxide, Earth became cooler.

The topic discusses the reason which causes the Little Ice Age, and the writer presents three arguments for this issue. Nonetheless, the writer's statements encounter serious dissensions from the professor and he introduces counterarguments.
First, the writer declares that the disruption of ocean currents result in the Little Ice Age, and it is because a period of unusually warm weather made the glacier melt into water and flow into the Gulf Stream, which became cold. By contrast, this seemingly plausible statement is critically rebuked by the professor's account from a conflicting angle that the Gulf Stream only influenced Europe and America, while some places such as New Zealand were still influenced. Therefore, only Gulf Stream can't explain the original cause of the Little Ice Age. Apparently, this author's point is rather untenable.
Second, the writer asserts that volcanic eruption, which produced many dark clouds of dust and sulfur gas, would block the sunlight to decrease the temperature and eventually form the Little Ice Age. On the contrary, the professor disclaims this statement and holds that it is illogical that dust and sulfur gas are visible, and it would have an uncommon color of sunset and different colors of snow. Moreover, no reports and records are found to prove this situation. Thus, the final conclusion might be prejudiced and carry little conviction.
Lastly, the writer claims that the human population will indirectly contribute to cool the temperature because many agricultural fields turned to forests that absorb carbon dioxide. However, the professor stands in stark opposition by pointing out that there was not enough time to absorb much carbon dioxide. Moreover, the human population grew back quickly, so many forests were cut down to feed the human being. Hence, the point expressed in the text is merely a false assumption.
