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 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 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 temperature. 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 reading states that Scientists are trying to found out what would occur the Little Ice age
and provides three possible causes of support. The lecturer challenges the proposals
made by the author and refutes each of the author's claims.
first of all, the article argues that disruption of ocean current might have caused the little
ice age. The lecturer challenges the claim. He says that this little ice age only explains the Europe and American
disruption but does not provide any explanation sothern hamisphere disruption. Additionally, he states that
southern hemisphere like Newzealand and south Africa also become cooler now this time and shortage their Ice age but author does not provide any specific reason for this happening.
Secondly, the article posits that after volcanic eruption dust and sulfur gas spread into the atmosphere and blocking sunlight thus, sunlight can not reach into the earth. as a result global temperature decrease day by day.
The lecturer, however, rebuts this claim that volcanic dust mainly striking visual effects. as a result, it occurs some color sunlight and produces gray or purple snow. On the other hand, these effects can not reported by the authors so, this dust effect not long enough to explain Little ice age.
Finally, the author asserts that human population declination would be occur indirectly to the cooling of climate.
In the article states that for declining population besides forest trees increases and then trees absorb large amount of carbon-dioxide and green house gasses and keep the earth cool. In contrast, the lecturer position is that it has not enough time to stay low of human population because, during short time, human population increas and cut down again large number of trees. Furthermore, He says that this assumption is not carrying any convincing idea and this population decreasing concept not long enough to long term effects of enormous global cooning and little ice age.
