Global Warming: Society s Warning
I feel strongly that global warming is affecting my community because it s effects reach across every town in every country across the entire planet. Global warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earth’s surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the coming decades. For the last 10,000 years, the Earth’s climate has been extraordinarily beneficial to mankind. “Humans have prospered tremendously well under a benign atmosphere,” (Bates 28). Today, however, major changes are taking place. People are conducting an inadvertent global experiment by changing the face of the entire planet. We are destroying the ozone layer, which allows life to exist on the Earth’s surface. All of these activities are unfavorably altering the composition of the biosphere and the Earth’s heat balance. If we do not slow down our use of fossil fuels and stop destroying, the forests, the world could become hotter than it has been in the past million years. Average global temperatures have risen 1 degree Fahrenheit over the last century. If carbon dioxide and other greenhouse gases continue to spill into the atmosphere, global temperatures could rise five to 10 degrees by the middle of the next century. The warning will be the greatest at the higher latitudes of the Northern Hemisphere, with the largest temperature rises occurring in winter. Most areas will experience summertime highs well above 100 degrees Fahrenheit. New temperature records will be set each year. As a possible prelude to global warming, the decade of the 1980’s has had the six hottest years of the century (Erandson 18-22). Atmospheric disturbances brought on by the additional warming will produce more violent storms and larger death tolls. Some areas, particularly in the Northern Hemisphere, will dry out and a greater occurrence of lightning strikes will set massive forest fires. The charring of the Earth by natural and man-made forest fires will dump additional quantities of carbon dioxide into the atmosphere. Changes in temperature and rainfall brought on by global warming will in turn change the composition of the forests. At the present rate of destruction, most of the rain forests will be gone by the middle of the next century. This will allow man-made deserts to encroach on once lush areas. (Bassett 1-2). Evaporation rates will also increase and circulation patterns will change. Decreased rainfall in some areas will results in increased rainfall in others. In some regions, river flow will be reduced or stopped all together completely. Other areas will experience sudden downpours that create massive floods. The central portions of the continents, which normally experience occasional droughts, might become permanently dry wastelands. Vast areas of once productive cropland could lose topsoil and become man-made deserts. Coastal regions, where half the human population lives, will feel the adverse effects of rising sea levels as the ice caps melt under rising ocean temperatures. If the present melting continues, the sea could rise as much as 6 feet by the middle of the next century (Bassett 1-2). Large tracks of coastal land would disappear, as would shallow barrier islands and coral reefs. Low-lying fertile deltas that support millions of people would vanish. The sea would reclaim delicate wetlands, where many species of marine life hatch their young. Vulnerable coastal cities would have to move farther inland or build protective walls against the angry sea, where a larger number of extremely dangerous hurricanes would prowl the ocean stretches. Forests and other wildlife habitats might not have enough time to adjust to the rapidly changing climate. The warming will rearrange entire biological communities and cause many species to become extinct. Weeds and pests could overrun much of the landscape. Since life controls the climate to some extent, it is uncertain what long-term effects a diminished biosphere will have on the world as a whole. It is becoming more apparent, however, that as man continues to squander the Earth’s resources, the climate could change in such a way that it is no longer benevolent to mankind. The greenhouse effect and global warming both correspond with each other. The green house effect is recalled as incoming solar radiation that passes through the Earth’s atmosphere but prevents much of the outgoing infrared radiation from escaping into outer space. The global warming refers to a long-term rise in the average temperature of the Earth. How do they correspond with each other? Simply, because without one, the other doesn’t exist. The natural greenhouse effect has kept the Earth’s average surface temperature around 33 degrees Celsius, warmer than it would be if there was no atmosphere. The natural gases in the greenhouse effect are water vapor, carbon dioxide (CO2), ozone (O3), as well as other trace gases. Life could not exist if there was no natural greenhouse effect. The reason for the natural greenhouse effect is so that all the creatures living on Earth can live and breathe. We as inhabitants of this Earth must do our part in preserving it, or there won’t be much left for our children to live on. Human activities are causing some greenhouse gases such as carbon dioxide to build up in the atmosphere. Each time we burn gasoline, oil, coal, or even natural gas, more carbon dioxide is added to the atmosphere (Erandson 34). By cutting down the forest trees, we allow air pollution to set in. This, therefore, causes many problems in addition to many others. Now that there are no trees to help filter out pollution, we are allowing more damage to the atmosphere causing global warming. These certain gases that occur naturally in the atmosphere tend to trap the sun’s heat, which is called global warming. By trapping in the sun’s heat, the Earth can be warmed up. Many of the Earth’s natural disasters, such as volcanic activity, and other factors, have caused our planet’s (Bates 23) atmosphere to become either colder or warmer. The global average temperature of the surface has increased by one degree Fahrenheit over the past century. This indicates that this warming trend is due to human influences. In conclusion, if there was no greenhouse effect then there would be no global warming. The greenhouse effect causes the global warming to increase as well as humans and other creatures influence. There are many ways to help prevent and protect both. Though the task is imposing, the clean energy revolution is coming along just in time, promising genuine climate solutions. Energy generated with clean sources such as solar energy, wind power, and hydrogen fuel cells represent both environmental promise and a phenomenal business opportunity. Schools can offer environmental education information, activities, and resources to teach the next generation about the consequences of transportation choices. This information could engage students and their families to choose and promote transportation alternatives such as walking, cycling, car-pooling and use of transit systems. Society as a whole needs to reduce, reuse, and recycle, by not creating waste–in the form of unnecessary products or packaging–people not only avoid having to manage it later, they also avoid having to expend the energy, consume the natural resources, and create the pollution that comes from manufacturing it in the first place. If everyone works together to implement global solutions, we will leave a healthy planet for our children s children to enjoy.
We do not own the earth, we are merely borrowing it for our children
