Reading 1: Global Warming: Fact or Fiction?
A. Read the article and answer the questions.
Global Warming: Fact or Fiction?
Global warming is one of the most controversial issues of our time. Some people believe that global warming is a real and serious problem that threatens the future of our planet. Others think that global warming is a hoax, a myth, or a natural phenomenon that does not require any action. Who is right? What is the evidence for and against global warming?
The term global warming refers to the increase in the average temperature of the earth's atmosphere and oceans. According to the Intergovernmental Panel on Climate Change (IPCC), a group of scientists from around the world, the global average temperature has risen by about 0.8 degrees Celsius since 1880. The IPCC also predicts that the temperature will rise by another 1.8 to 4 degrees Celsius by the end of this century, depending on how much greenhouse gases are emitted into the atmosphere.
Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, are gases that trap heat in the atmosphere. They are produced by burning fossil fuels, such as coal, oil, and gas, as well as by deforestation, agriculture, and other human activities. The more greenhouse gases there are in the atmosphere, the more heat is trapped, and the warmer the earth becomes.
The supporters of global warming argue that this increase in temperature will have devastating consequences for the environment and human society. They claim that global warming will cause more extreme weather events, such as droughts, floods, heat waves, storms, and hurricanes. They also warn that global warming will melt the ice caps and glaciers, raising the sea level and flooding coastal areas. Moreover, they say that global warming will endanger many species of plants and animals, leading to mass extinctions and loss of biodiversity.
The opponents of global warming, on the other hand, challenge the validity and reliability of the scientific evidence for global warming. They question the accuracy of the temperature measurements and models used by the IPCC. They also point out that there are natural factors that influence the climate, such as solar activity, volcanic eruptions, and ocean currents. They suggest that these natural factors may be more important than human activities in causing climate change. Furthermore, they argue that global warming may have some positive effects, such as increasing crop yields, opening new trade routes, and creating new opportunities for tourism.
So who is right? Is global warming fact or fiction? The answer is not simple or clear-cut. There is still a lot of uncertainty and debate among scientists and policymakers about the causes and effects of global warming. However, one thing is certain: global warming is a complex and important issue that affects everyone on earth. Therefore, it is essential that we learn more about it and take action to protect our environment and our future.
