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 southern harsh winters, and glaciers grew also 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 evidence 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 reading passage discusses several causes that might have led to the little ice age. However, the speaker in the lecture casts doubt on the claims made in the article. He mentions that the arguments in the article are outdated and new information simply disproves all of them.
First and foremost, the author believes that the disruption of the gulf stream by the melting glaciers could be the reason behind the drop in earth's temperature. The lecturer, on the other hand, points out that if this was the case, the decrease in temperature should have been observed only in Europe and North America. On the contrary, the cooling effect affected the southern hemisphere too, such as New Zealand and South Africa. Thus, this hypothesis could not be true.
Secondly, the writer argues that volcanic activity could have sent dust into the atmosphere, which, in turn, would have blocked sunlight and decreased global temperatures. In contrast, the lecturer brings the fact that people at this time did not report any visual effects, which are expected under these circumstances, such as a colored sun or brown snow. Hence, this argument lacks coherence.
Lastly, the author contends that the decline in human population during this era allowed more trees to grow in forests and as a result, these trees absorbed most of the carbon dioxide, which is the greenhouse gas responsible for keeping the earth warm. The lecturer challenges this proposal. He holds that there was not enough time for this to happen as the human population started to regrow fairly quickly cutting down trees and clearing up forests for agriculture. Consequently, the trees were not there long enough to cause a cooling effect on earth.
