Answer:
One of the earth’s greatest challenges is Global warming. It is described as a constant increment in the earth’s average temperature. It is believed that global warming would result in permanent climate change. In line with the research, as human beings burn fossil fuels and destroy forests, the temperature of the earth rises steadily due to emissions from such activities. From the beginning of the industrial revolution, there has been a continuous discharge of carbon into the atmosphere.
Majorly, global warming is caused by human activities. Over the past century, the average temperature of the earth has increased significantly. According to scientific research, greenhouse gases released into the atmosphere by human activities have led to temperature increase since the mid-20th century. Most researchers indicate that the planet’s temperature has increased by 0.5˚C since 1900.
The impacts of temperature increase are experienced all over the world. Over the next 100 years, global temperature is expected to rise from 1.4°C to 5.8°C. This trend is expected to continue in the future and the earth would get warmer every year. This paper explores the causes, effects, and prevention of global warming.
Causes of Global Warming
Majorly, global warming is caused by the greenhouse effect, which is defined as the natural process through which the atmosphere absorbs the energy of the sun heating up the earth. The sun’s thermal radiations are absorbed and redirected in all directions by greenhouse gases, produced when fossil fuels are burnt. The clearing of forests also results in an increase in carbon dioxide in the atmosphere. The major greenhouse gases include carbon dioxide, ozone, water vapor, and methane. Coal and oil mining, landfills, and natural gas seepage also release methane into the atmosphere. In addition, melting of ice, containing methane clathrate, releases methane which also results in a considerable increase in global temperature.
Another cause of global warming is deforestation. Cutting down trees reduces carbon dioxide absorption and release of oxygen by plants. As a consequence, carbon dioxide concentration builds up in the atmosphere, which leads to the greenhouse effect. Atmospheric carbon dioxide level is also increased by burning wood, which emits oxidizable carbon. Other gases such as nitrous oxide released by fertilizers, refrigeration gases, chlorofluorocarbons (CFCs), and industrial wastes also cause global warming.
CFC does not absorb heat, however, UV rays cause chlorine to disintegrate from CFC. Free chlorine catalyzes the conversion of ozone molecules into oxygen. This causes the depletion of the ozone layer and leads to global warming. Icebergs and glaciers reduce the earth’s temperature by reflecting high-temperature beams back into the atmosphere. However, the removal of icebergs due to melting causes the earth to get warm since the ocean would absorb much thermal radiation from the sun(Archer 29).
Prevention of Global Warming
The prevention of global warming requires everybody’s effort. There are several measures that need to be taken to prevent global warming. Majorly, prevention involves controlling or stopping those human activities that cause global warming. Emissions of greenhouse gases should be monitored and prevented. Deforestation and burning of wood should be prevented because it increases carbon dioxide concentration in the atmosphere. In remote areas, LPG stoves and Biogas use need to be supported to reduce the burning of wood. The emissions from automobiles that cause global warming can be reduced by using fuel-efficient cars.
In addition, the use of electric cars, bio-fuels, and the proper design of car engines can be encouraged to minimize such emissions. Public education could play a key role in preventing global warming. Mostly, global warming is caused by people’s ignorance and bad attitude. Young people should be educated on the need for environmental conservation and responsible use of resources bearing in mind the harmful effects of global warming. Media should play a critical role in educating the public and raising awareness of the negative impacts of environmental pollution.
