The reading passage and the lecture both
talk about a cause of the Little Ice Age. The author of the reading suggests
three possible causes of the Little Ice Age. However, the lecturer rebuffs the
reading passage’s arguments by giving three convincing evidences.
To start with, the lecturer asserts that diminished
solar radiation is not the cause of the Little Ice Age. To be specific, even
though observable sunspots were decreased, it was not responsible to total
amount of solar radiation. Therefore, she says there is no prove that diminished
solar radiation led the Little Ice Age. However, this view is in direct opposition
to the reading that says diminished solar radiation caused the Little Ice Age.
On top of that, the lecturer mentions that
the Little Ice Age lasted more than five years. However, a volcanic eruption
worked only for a while. Therefore, she claims that the volcanic eruption does
not take into consideration. On the other hand, the author of the reading
asserts that a massive volcanic eruption triggered the Little Ice Age by
reducing an amount of solar radiation.
Finally, the lecturer argues that an
increase in the Earth’s reflectivity is not the significant reason of the
Little Ice Age. She supports her idea by suggesting that an amount of cloud
cover decreased in the Little Ice Age because of declined water evaporation. This
view is contrary to the reading passage that asserts that the Little Ice Age
was caused by the increase in the Earth’s reflectivity.
