The reading and the listening are about Little Ice Age specifically what the reasons were behind this. The author of the passage suggests three possible assumptions for this harsh winters age. However, the professor in the lecture avers that the writer' s explanations were outdated and refutes all of them.
First of all, the writer mentions that ocean current was one of the reasons for that natural climatic condition. He also states that since the temperature was increased prior to the Ice Age, glaciers melted and produced huge freshwater and that break down gulf current which leading the formation of the Little ice age. The professor rebuts this point by implying shreds of evidence of southern part where no such glacier melt or gulf currents disrupted. He also informs that that gulf stream was not responsible for that Age.
Secondly, the author states that since volcanic eruptions produce a huge amount of dust and gas which create a sunlight block, the volcanic eruption may be the possible reason for that freezing season. However, the lecturer says that even though volcanic eruptions might be the reason of that Age, but the other consequences of eruptions were not documented by anyone. He also posits that if that occurred, the colorful sky would remain for a long time, yet such no evidence had found. So, volcanic activities were not the main reasons for that age.
In the third assumption, the writer claims that population declining because of many reasons before starting the ice age might create a condition for growing forest trees. He further implies that growing large plants may absorb carbon dioxide and reduce greenhouse effect, and that helps to start that age. The professor, however, refutes this point by saying that to produce such age, must need more time. But human population regained their position and population was increased; as a result, they cut all forest trees to crop for feeding themselves. So, humans were not the reason for little ice age.
The reading and the listening are about
Little
Ice
Age
specifically
what the
reasons
were behind this. The author of the passage suggests three possible assumptions for this harsh winters
age
.
However
, the professor in the lecture avers that the
writer&
#039; s explanations
were outdated
and refutes all of them.
First of all
, the writer mentions that ocean
current
was one of the
reasons
for that natural climatic condition. He
also
states that since the temperature
was increased
prior to the Ice
Age
, glaciers melted and produced huge freshwater and that break down gulf
current
which leading the formation of the
Little
ice
age
. The professor rebuts this point by implying shreds of evidence of southern part where no such glacier melt or gulf currents disrupted. He
also
informs that that
gulf stream
was not responsible for that Age.
Secondly
, the author states that since
volcanic
eruptions
produce a huge amount of dust and gas which create a sunlight block, the
volcanic
eruption
may be the possible
reason
for that freezing season.
However
, the lecturer says that
even though
volcanic
eruptions
might be the
reason
of that
Age
,
but
the other consequences of
eruptions
were not documented by anyone. He
also
posits that if that occurred, the colorful sky would remain for a long time,
yet
such no evidence had found.
So
,
volcanic
activities were not the main
reasons
for that age.
In the third assumption, the writer claims that population declining
because
of
many
reasons
before
starting the ice
age
might create a condition for growing forest trees. He
further
implies that growing large plants may absorb carbon dioxide and
reduce
greenhouse effect, and that
helps
to
start
that
age
. The professor,
however
, refutes this point by saying that to produce such
age
,
must
need more time.
But
human population regained their position and population
was increased
;
as a result
, they
cut
all forest trees to crop for feeding themselves.
So
, humans were not the
reason
for
little
ice
age
.
