Causes And Effects Of Global Warming Essay Sample

What exactly is global warming and why is it worthy of consideration? Global warming is the scientific phenomenon linking an increase of the average earth temperature because of a trapping of radiation within the earth like a greenhouse. This has been a natural phenomenon throughout the natural history of the world but it has only become a problem in the last few hundred years because of an anthropogenic increase in greenhouse gasses. This essay on global warming needs to look at the causes of the problem. Global warming is caused by an acute heating of the earth’s atmosphere as a result of energy being trapped. Greenhouse gasses such as carbon dioxide and methane can cause the atmosphere to build up, leading to solar radiation becoming trapped within the earth like within a greenhouse, hence the name. Over time, the trapping of this radiation leads to the earth’s atmosphere rising in temperature and the earth becomes warmer as a result.

The causes of global warming are both natural and anthropogenic but the anthropogenic influence is the most damaging. Global warming is also largely a result of the release of methane from cracks in the earth, landfill sites and through natural gas leaks. Methane has an effect on the atmosphere which is four times as bad for global warming as carbon dioxide. Cattle and other animals that produce methane can also contribute significantly to global warming, much of this has been a problem because of human animal farming which produces hundreds of cattle for the meat industry. The reason as to why global warming is such an issue today is because of the problem that humans are creating with anthropogenic contributions to greenhouse gasses. Many of the practices that humans employ create enormous amounts of greenhouse gasses to be released and this has been well documented to be significantly harming the earth.

Modernity, modern technology and new lifestyles have resulted in human activities that produce a lot of greenhouse gasses such as deforestation, the combustion of fossil fuels, industrial action and farming animals. The growing rise of industry around the world and the rise of consumerism has resulted in the production of many goods, all using fossil fuels either directly or indirectly. Consider the example of something trivial a mobile phone – creating something like this will lead to a large amount of components that need to be made using fossil fuels. Even if we want goods that have been grown on trees in our homes, they will need to be transported somewhere by transport that uses fossil fuels. There’s no real escape from it – fossil fuels are in the fabric of modern life. Mining causes methane and natural gas to escape from where it is trapped below the earth. Deforestation is one of the biggest causes of global warming.

Not only are trees cut down to make goods that need to be transported using fossil fuels, the removal of trees leads to a net loss of photosynthesis which is carried out by plants to make food. In this process, carbon dioxide can be absorbed and turned into oxygen, making food for the plants and cleaning the atmosphere as a result. The wide scale removal of trees and biodiverse life results in a large amount of carbon dioxide that can’t be converted to oxygen and so a huge problem for global warming. Global warming and greenhouse gasses are problematic as they raise the earth’s temperature, but exact effects of global warming exist and what effect will global warming have for our planet and our society in the future? Polar ice caps can melt, there will be widespread flooding all over the world, there will be an increase in the frequency and intensity of harmful natural disasters and the consequences to the economy will be detrimental to societal progress.
