Business Manmade chemicals are proven to be the major cause of global climate change as such cause increased atmospheric temperature which can lead to unfavorable water patterns, growth patterns, and weather. Unfortunately, man cannot do away with such chemicals that easily as these are needed in producing and refrigerating goods, and in making lives easier. As such, the U.S. and international governments are establishing regulations to limit the usage of manmade chemical substances that deplete the ozone layer, have a high global warming potential, or increase the fugitive emissions related to Greenhouse Gases (GHGs). Refrigerant gas used to run commercial refrigeration units, as well as air-conditioning systems and heating, ventilation and air conditioning systems, is a chief cause of climate change because it is made up of hydrochlorofluorocarbons and chlorofluorocarbons. These gases contribute to global warming and also deteriorate the ozone layer. Because of the great harm refrigerant gas can cause to the Earth, the United States and many international countries are phasing out its usage, with complete removal by 2015. Fossil fuels are a major cause of climate change because they lead to an increase in greenhouse gases in the atmosphere. The high carbon dioxide emitted from the use of oil, natural gas, and coal for running vehicles and operating machines are identified as one of the largest causes of global warming. Fossil fuels also produce carbon monoxide, methane emissions, nitrous oxide and nitrogen oxides, all substances that impact air quality and global warming. Scientists have found that methane is a significant cause of climate change. This greenhouse gas is discharged by cows, pigs, horses, sheep and other domesticated animals. Methane gas is also discharged from garbage in landfills, fertilizers, oil drilling and coal mining. In addition, when a gas leak occurs, a high volume of the dangerous chemical is discharged at one time. Climate change is largely caused by the destruction of the ozone layer. It occurs from things we use every day. Commercial refrigerators, freezers, air conditioners, and heating, ventilation and air conditioning systems all contain harmful gases that continue to destroy the ozone layer. Refrigerant gases like hydcrocholoflurocarbons (HCFCs) and chlorofluorocarbosn (CFCs) are harmful gases but which are used largely for cooling equipment and refrigeration. Several factors are identified to be the cause of climate change. Such include animal agriculture, land use, deforestation, cement manufacturing and aerosols. To pinpoint measures which can help minimize impacts on global warming, such areas are being studied. Many types of pollutants are a cause of climate change. Common pollutants are carbon dioxide, methane, black carbon and nitrous oxide. As these chemical pollutants increase, the ozone layer gets depleted, which results to global warming. Experts signify the need to address global warming, otherwise, planet earth will be totally destroyed. Simply put, too much heat stored in the atmosphere is the cause of climate change. The amount of greenhouse gases in the air contributes to atmospheric heat. Increased heat on lands, oceans, and the atmosphere has changed the Earth’s climate. As a result, human, animal, plant and marine life will be severely impacted. About the Author: 相关的主题文章:
