Writing and lecture are both about debating the causes that lead to the little ice age, which took place in the past. On the one side, the writer describes three plausible reasons for this. On the other side, the lecturer casts doubts on the claims made by the writer, saying that his arguments are somehow inaccurate when compared with recent knowledge.
First, the cooling was not caused by disrupting of ocean currents. The author states that when glaciers melted the water went to Gulf Stream, a region that has a significant impact on the planet's climate. However, the speaker refutes this idea, asserting that it affects only Europe and North America, while the little Ice Age occurred in Southern hemisphere as well, hence the speaker's theory does not stand up.
Second, volcanoes affects the climate only when their eruptions have catastrophic proportions, whereas there is no evidence of such monumental events. People would have noticed changes in the atmosphere or other meteorological phenomena such as gray snow, but there are no records about such situations. In other words, if volcanoes' activity is not strong enough, dust and sulfur does not cover the atmosphere for a long time, and therefore the climate is stable. So, this is a strong standpoint against passage.
Third, the population decrease only during a short period of time. The author suggest that when the human population started to go down, many places which were used for agriculture, were covered by forest, and because forests absorb carbon dioxide the temperature decreased. Anyway, the speaker rejects this by underlining that humans' number started to grow shortly after this crisis, and thus the forests were cut down pretty fast. Consequently, there was to little time for climate change to happen. To summarize, the speaker and the lecturer seem to be in total disagreement regarding this topic.
