▶ Your Answer :
The lecturer argues that it is doubtful
that the Little Ice Age was caused by three processes the reading argues. This
contradicts the reading passage’s claim that the Little Ice Age was bring about
by cooling of the Gulf Stream, volcanic eruptions and decrease in the
population.
First, the lecturer contends that a theory
that insists Gulf stream evoke Little Ice Age is hard to believe. The Gulf
Stream provoked temperature to drop down in Europe like Ireland and Great
British and just Northern Europe. However, Southern Hemisphere like New Zealand
South Africa experienced the Little Ice Age which Gulf Stream was not near
them. On the contrary, the reading passage contends that the Gulf Stream
affected the Little Ice Age to appear.
Next, the speaker gives a voice that
volcano eruption could not affect temperature to decrease in that day. For instance,
Tembora in Indonesia volcano erupted. After this situation, many ashes appeared
and cover the sun which also called that year without summer. Theory said that the
little ice age was continued over the centuries that made super volcano to
appear. However, there were no any super volcano erupted back then. Contrary to
the lecturer’s claim, the reading passage insists that volcano eruptions made
temperature decline.
Finally, the speaker asserts that forest
could not grow up quickly affected by temperature. By 1450, Europe population was
back to Pre-Black death level, this situation caused to deforest by people.
Therefore, carbon dioxide was increased by this and this rule out the tree
theories. This refutes the reading passage’s claim that decrease population can
affect carbon dioxide to drop down and had global cooling.
