▶ Your Answer : In the reading passage, there is an ample
support for the author's claim that global warming has caused a great deal of
concern because even small changes in global temperatures can have devastating
environmental effects.
However, the professor in the lecture gives
several reasons as a rebuttal to the author's point.
First of all, the professor contends that
methane produced by landfills is not a significant contributor. According to
the result of a study, global warming is mainly caused by human. The effect on
landfills is very few and thus it cannot be a important element of global
warming
This casts doubt on the reading passage's
assertion.
Next, the professor insists that it is not
true that deforestation is a factor of global warming. Furniture can absorb
carbon dioxide. Therefore, deforestation has no effect on increasing average
temperature. The professor says that it is just delaying the process about
absorbing carbon dioxide and so it is not able to be a cause of global warming.
This counters on the reading passage's
suggestion.
Finally, the professor argues that the current
warming trend is associated with a naturally occurring cycle of climate change.
The temperatures in the world are different according to the location. This is
mainly due to the fact that global warming cause increasing temperatures of the
world totally. So, naturally occurring cycle of climate change is not an
evidence. This refutes the reading passage's claim |
