Global Warming is the increase in the Earth’s external temperatures. a little boring and simplistic. does not even begin to describe the complexities of the issue. your second sentence, however is awesome! Make your second sentence your first sentence and replace it w/ Global warming It is the reason for many recent worldwide issues such as severe weather conditions, droughts, and various other environmental changes. Though people’s view on the severity of global warming is highly controversial, the effects of global warming are evident and severe, and drastic changes in living style must be made to ensure a safe and comfortable environment for everyone to live in. People all over the world should work together to lessen the effects of global warming because everyone shares this one and only earth. Kind of wordy and cheesy When making policies that may affect global warming, leaders should consider reducing the combustion of fossil fuel ﻿fossil fuels (its plural) and protecting wild endangered species. Should have a longer and stronger thesis Maybe mention a brief why in there or the consequences. what would this do for global warming? Leaders should address the issue of burning fossil fuel because it is the leading cause of global warming. Combustion of fossil fuel “accounts for nearly three-quarters of carbon dioxide emissions.” [Source A] Three-quarters of all carbon dioxide emissions is a very big quantity; thus by reducing the combustion of fossil fuel, people will also be reducing a great amount of carbon dioxide emission. Also, the greenhouse-gas emission has caused the world’s average surface temperature to increase. Even though the rise in temperature seems subtle at the moment, only an increase of “approximately 1 degree Fahrenheit”, it is still “the fastest rate in any period over the last 1,000 years.” [Source A]. If temperature continues to increase at this fast speed, the earth can become too hot for human inhabitation in the near future for coming generations. By reducing burning of fossil fuels, people will not only be able to reduce carbon dioxide emission, but also be able to save energy and slow down the rise of the earth’s surface temperature. The second issue leaders should address besides reducing combustion of fossil fuel is the issue of endangered species due to global warming. awkward phrasing There are signs that “spring is appearing earlier” each year. [Source F]. As spring approaches earlier each year, many species of birds are tricked into believing spring has actually arrived. As a result, these fooled birds are “wiped out by spring snowstorms” that come unexpectedly. [Source F]. Biologists explain that the “global environment is changing so fast that the slow evolutionary process of species adaptation can’t keep up”, and as a result, many species become endangered. [Source F]. With the apparent evidence that animals are being threatened by global warming, there is no doubt that global warming has indeed become a serious problem. redundant Also, there is evidence that the ocean’s temperature has also increased dramatically over the last one-hundred-fifty years [Source B]. With the melting of the Arctic and many ice glaciers, habitats for many of the animals are being destroyed. This rise in sea level not only results in the melting of cold environment for animals at the Arctic, but also results in the destruction of habitats for other animals all over the world because the increase in water is also shrinking dry land and drowning islands. Leaders should take action to save endangered species by finding ways to slow down global warming. <--through their policies? Overall, global warming is indeed a very serious problem. It is changing the earth and the earth’s climate. redundant, wordy Policies for reducing fossil fuel combustion must be made not only to save endangered species, reduce global temperature, but also to save the very race of human beings. Some people do not realize the great dangers of global warming until they personally experience the disasters global warming brings, such as hurricanes, while others are simply unaware or do not care of its effects. If global warming is to continue, untreated, humans may very well be the next endangered species of the future! Good conclusion
