Global warming (Сочинения ЕГЭ английский язык)

Both in the lecture and in the passage the same topic is discussed : whether global warming depends on human’s activity or not. While the reading states that global warming is something natural, not human-made, the lecture suggests that we still play a great role in causing that environmental problem The lecturer cast doubts on what is written in the passage by providing three reasons.

First of all, according to the reading, CO2 is a gas that comes out from the carbon sinks when the Earth warms itself. So it does not depend on human’s activities. However, the lecturer disagrees, mentioning that part of the CO2 is produced by burning, which is what people do.

Secondly, in the passage it is written that computer modeling is not accurate because it can not even predict future climate patterns without failure.

Besides, computers can not measure GMST, the global mean ocean surface’s temperature, which is claimed to be important by scientists.

However, the lecturer claims that this is not true. She says that there are a lot of other things that are used to measure global warming.

Besides, she mentions that the amount of CO2 is increasing noticeably, so we did not even need the computers to notice this.

Thirdly, in the passage it is mentioned that water vapor is a natural gas that concentrates due to the storms and ocean currents. On the other hand, in the lecture it is said that water vapor’s increase also depends on fires, which happen due to human activities.

To sum up, through both in the lecture and in the passage the same topic is discussed, three main points made in the passage are effectively challenged by the lecturer.
