The reading states that global warming is a fact and provides three reasons of support. The professor explains that the global warming can exist but the evidence used in the article cannot be true and scientist do not know if the temperature has been rising or not, and so he refutes each reason mentioned in the reading.
First, the reading claims that the data from sophisticated instruments around the world has proved a warming trend. The professor contends that the temperature from those thermometers show the increase but not all of the thermometers should be trusted. He explains that they took the data from all well-maintained weather stations and averaged them and there was no increase in the temperature after 1979.
Second, the article posits that the alarming rate of breaks in the ice shelves of Antarctica is another reason to prove this trend. The professor opposes this by saying that this information is flawed. He states that it is true that icebergs break but the theory fails to explains the evidence of warming and cooling. He also adds that we cannot assume the break happened because of increase in the temperature. Maybe it happened unnaturally. So, the subject needs to be more studied and more time should be spent to learn about reasons.
Third, the reading avers that unbiased organizations such as reliable newspapers and interantional organizations have considered considered the evidence and accepted the fact. However, the lecturer refutes this point by mentioning that newspapers were published before the report was ready and evaluated thoroughly and it was not examined enough.
