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 1900C.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 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 absorbing carbon dioxide, earth became cooler.
The lecture and the passage are both discussing the possible causes that led to the extraordinary period of cold temperature known as “The little Ice Age”. In the lecture, the professor believes that none of the mentioned theories is convincing and out of date. On other hand, the writer believes that one of the stated hypotheses is the main cause.
To begin with, the hypothesis that the cooling could have been happened due to disturbing of ocean currents, specifically in the gulf stream is not true. In fact, scholars concluded the change of Gulf stream current could only change the climate in Europe and North America. However, they found out that the southern hemisphere was affected also such as Southern Africa, and New Zealand. Therefore, the theory cannot explain the process of ice age developing, since the southern area have been affected along with the Gulf ocean surrounding areas. This casts doubt on the reading which states that disruption of the Gulf Streams could have led to the formation of the Ice Ag.
In addition, the lecturer states that volcanic theory has limitations. This is because a strong volcanoes eruption produces a large amount of dust in the atmosphere. Therefore, the dust changes the ice color into brown or gray, and the sunset becomes colorful. Although volcanoes had happened, but none of the native people who used to live in the Gulf stream reported change in the ice or the sunset color. Consequently, the volcanos eruption was not strong enough to cool the area. This opposes the author which states that volcanic eruption might have led to cause the Littlie Ice Age.
Finally, the speaker explains why the significant decreased in human populations and the overgrew of forest trees could not be the main reason. This is because the human population came back in a short period of time. Moreover, they cut down trees to clear field for crops harvesting. As a result, the forests didn’t have enough time to cause cooling of climate. This opposes the author which states that the huge amount of forest trees would have resulted in cooling the area.
