Global Warming
Over the last few decades, there has been a warming trend across the globe. Many view this perceived pattern of increasing temperatures as unnatural and a result of the surge in carbon emissions produced by industrialized nations. Though some may debate the possible causes, one fact is certain: we are experiencing a global warming. The evidence for this is clear.
First, data from sophisticated instruments across the globe indicate a warming trend. Throughout the world, thermometers from weather stations on the surface of the Earth take readings of the temperature. These instruments have kept detailed records of temperature changes for over a century. The average of the temperatures recorded by all of these instruments plotted over time indicates that there is a general warming occurring across the globe.
Also, secondary evidence points to rising temperatures. For one, scientists have reported an alarming rate of breaks in the ice shelves of Antarctica. Specifically, a recent break of a reportedly 53 mile long and 40 mile wide iceberg. This unusually high number of icebergs calved from Antarctica in recent years has prompted many to see the reality of global warming, since excessive warming would cause the ice in Antarctica to become weak and break as it has.
Third, impartial, unbiased organizations such as respected newspapers and international organizations have considered the evidence and accepted as fact the idea that there is a warming trend. For example, major newspapers published part of a United Nations Environment Program (UNEP) climate report expressing grave concern over global warming. The report states that the climate has warmed over the last 50 years and that computer models predict an astounding 10-degree increase in the next 100 years with severe consequences for life on Earth.
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.
