Global Warming

Global warming means a gradual increase in the Earth's average lower atmosphere due to emissions and build up of greenhouse gases . Global warming is when the earth heats up and the temperature rises. It happens when greenhouse gases such as carbon dioxide, water vapor, nitrous oxide, and methane trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. Most greenhouse gases are released by the burning of fossil fuels for heating, cooking, electrical appliances, transportation, and manufacturing, but they are also released as a result of the natural decomposition of organic materials, wildfires, deforestation, and land-clearing activities. The diffusion of these gases results in the spread of various epidemics, I believe that the repercussions of the soaring temperature are serious and irreversible. Global warming is a problem that could have devastating long term consequences. It causes sea levels to rise everywhere, permanently flooding many low lying parts of the earth. Many geographical areas may experience reduction in crop yield due to drier and hotter condition. In particular, global warming will cause the extinction of many under water species. Also, the higher temperatures contribute to the melting of glaciers and expansion of ocean water as it heats up, both of which cause sea level to rise. Higher sea levels erode beaches, increase storm surges, lead to a loss of wetlands, and can compromise freshwater supplies by introducing saltwater. Global warming will cause destruction of whole forests due to environmental changes and forest fires, and an increase in extreme weather such as tsunamis. It will also lead to increased human illnesses and deaths. Climate change also is likely to increase the number of species that are listed as threatened or endangered. There are innumerable reasons for global warming. Burning of fossil fuels is the one of the primary causes for global warming. It results in the release of carbon dioxide which not only adversely affects the environment but also affects its inhabitants. Fossil fuels like coal, natural gas and oil are non renewable and cannot be replenished once they are exhausted. The second noteworthy cause for global warming is the emission of black carbon. This fuliginous smoke is discharged due to the incomplete combustion of engines, wildfires and cook stoves. Deforestation which is cutting down of trees and clearing up of land also adds to the rising levels of carbon dioxide in the atmosphere. Deforestation deeply impacts the climate and the ecological balance. The local climate and the global fluxes of oxygen and carbon dioxide are disturbed due to the cutting down of trees. Also, deforestation leads to loss of the top soil which is protected by the forests.  Beef production also adds to the problem of global warming. Farmed animals such as cows and sheep emit huge quantities of methane via burping. These animals produce massive amounts of manure, which emit green house gases and increase the problem of global warming manifold. Lastly, CFC’s which were initially introduced as a substitute to harsh greenhouse gases, emit hazardous greenhouse gases incrementing the problem of global warming. As a public policy maker, I would make attempt to address the issue of global warming by instituting laws, regulations, decisions, or actions pertinent to the problem at hand. When climate change is taken into account, there is a broad range of stakeholders to consider such as the policy think tanks, non-governmental organizations, academia, government organizations and the private sector because many societal and environmental issues come into the consideration. Stakeholders can be divided into proponents and opponents of legislation to reduce greenhouse gas emissions to reduce global warming. Proponents include activists in environmental organizations, policymakers, governments and business groups who benefit from...
