The little ice age was a period of unusually cold temperature in many parts of the world that lasted from about the year 1350 until 1900CE. There were unusually harsh winters, and glaciers grew larger in many areas. Scientist have long wondered what caused the Little Ice Age. Several possible causes have been proposed.
First, the cooling may have been caused by disrupting 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. Such a disruption could have caused the Little Ice Age.
Second, volcanic eruption 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 eruption 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 reason(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 carbon dioxide, earth became cooler.
The author of the reading passage believes that the little ice age between 1350 until 1900 C.E. caused by melting ices, volcanic eruptions and lessening the human population. Supporting his opinion, he provides three reasons.The proferssor however rejects this arguments as follows.
To begin with, the author astats that before the little ice age took place, there was a short time of global warming which led to melting the polar icebearges. the melting ices streamed in the gulfs, decreasing the temprature of the gulfs and then all of the earth. this however, rebutted by the professor arguing that gulf strams could just affect the northern hamsphier, while we know that the southern hamspheir was also affected and became cool. Therefore this could be not a convincing theory. this is in direct contradiction to the reading reasoning regarding the gulf stream effect on earth temperature.
In addition, unlike the writer who maintaines that the volcanic eruptions could also concidered as another reason for the little ice age, the lecturer is of theopinion that if there were such great eruptions at that time, some reportes should be recieved to us about them because such great eruptions have striking visual effects. however, we do not have any report based on this phenomenon. this is also in sharp contrast to what the reading passage mentioned about the role of volcanic eruptions in the accurence of the little ice age.
Finally, while the author asserts that decreasing in human population caused the lessening in agriculture and thus it led to have more forests which could absorbe the dioxid carbon so make the earth cooler, the lecturer refutes this argument and points out that forests did not last enough time to be able to make the earth tempreture lower. Hence after a short time again we had a normal human population who need to remove the forest for farming fields. this is again another blow to the integrity of the argument put forth by the author of the reading passage.
For these reasons, the professor dismisses the argument of the writer as unconvincing.
