In this set of materials, the reading passage states that there are several possible causes which produced the little ice age in many part of the world. However, the lecturer finds all the idea out of date and provides some evidence to refute them all. He believes that scientists discovered new information regarding the change of climate.
First of all, the author of the passage claims that disrupting of ocean currents may send a large amount of cold fresh water into the Gulf Stream. In contrast, the lecturer argues that the Gulf Stream can affect Europe and North America. This reason cannot support the cause of the little ice age in New Zealand and South Africa. Hence, it is not the main and convincing reason.
Furthermore, it is mentioned in the reading passage that the phenomenon is because of volcanic eruption and its sulfur gas. On the contrary, the lecturer contends that a strong eruption is necessary for this effect which is distinguishable by vision. People must see brown sky and colorful clouds but nobody report it. So, regular volcanic eruptions are not enough to produce this effect.
Finally, the reading passage asserts that human populations decreased dramatically in the past due to warfare and disease which increased forest trees. Conversely, the lecturer illustrates that trees need a long time to grow and after a short time human populations started to increase and counteract the effect. Since they cut down woods again to plant crops, forest trees could not absorb significant amount of carbon dioxide. In fact, this event is not a logical consequence of decreases in human populations.
