The issue of climate change has provoked much controversy lately. While some people believed that climate change is simply the natural warming and cooling variations in climate system, it seems that human activity is contributable to that phenomenon, especially to the extent of greenhouse effect. Greenhouse effect is known as a naturally occurring process that aids in heating the Earth's surface and atmosphere. In actuality, it is undeniable that the enhanced greenhouse effect is mainly caused by human activities, including the combustion of fossil fuels and deforestation. The first problem to be elaborated is that the combustion of fossil fuels in industrial activities and transportation directly leads to the increased greenhouse effect.
Since the industrial revolution, we have been relying on extracting and burning billion tons of fossil fuel which are oil, natural gas, and coal. These fossil resources generate gasses such as CO2 that lock up the heat and result in major changes in the climate. As a result, burning fossil fuel is a major cause of global warming, because it increases the concentration of CO2. The United Nation Environment Program states that the carbon dioxide emissions that human is producing from fossil fuel today equals “5.9 billion metric tonnes of carbon in 1992” which is three quarters of the total CO2 produced by human in general (http://unfccc.int, 2000). We use and burn fossil sources for many purposes such as generating power, transportation, burning and cutting trees, creating chlorofluorocarbon, and many other industries.
Climate change can be defined as the long-term variations in atmospheric temperature, precipitation and weather patterns, and the main culprit for this drastic change is Global warming. Which is thought to be man-made. However over the course of history, throughout these 6 billion years the death has had these drastic climatic variation, for which natural factors had been held responsible. However after the Onset of the industrial revolution there has been fundamental change in the nature of the atmospheric system. The earths climate is driven by a continuous flow of energy from the sun.
Carbon dioxide emanations is the most vital reason for the whole earth’s temperature boost. CO2 is made by flaming sources, such as oil, regular gas, diesel, natural diesel, petrol, natural petrol, and ethanol. Most people do not know that when carbon dioxide is discharged to the environment, it stays for 100 to 200 years. As a result, this leads to an expanding concentration of carbon dioxide in the air, which thus causes the normal temperature of the earth to raise. Martin Rees (2016) , a professor of cosmology and astrophysics , writes in his article ”Human Induced Threat” that the atmosphere of CO2 focus is increasing for the most part because of the heated of fossil powers.These auto fumes vent these gasses into the air, and they turn out to be a piece of the air, leading to global
Global warming is described as the large and gradual increase in temperatures on the earth’s surface and the lower atmosphere caused by an increase in greenhouse gases such as carbon dioxide and methane (Soon, Baliunas, Robinson, & Robinson, 2001). While some factions of scholars, researchers and scientists describe Global warming as being natural, others believe it’s man-made. Naturally, the water vapor present in the air and clouds absorbs and therefore traps heat in the earth’s atmosphere which would otherwise be lost into space. The presence and increase of greenhouse gases further contribute to the greenhouse effect which leads to global warming by trapping more heat. In the period before the industrial revolution, climate change was largely due to natural causes especially changes in solar irradiance and volcanic activity (Crowley, 2000).
Global warming, also referred to as climate change which means a current increase in temperature of the earth’s surface as well as it’s atmosphere due to rising levels of greenhouse gases. It is a big issue of the atmosphere on the earth. It is caused by the human as well as by natural events. Human is the causes for emission of greenhouse gases such as methane, nitrous oxide, and carbon dioxide. Over the past 100 years, the earth has warmed by about 1°F.
Scientists discovered that carbon dioxide is an important effective gas for the greenhouse effect. Moreover, gases like carbon dioxide, methane and water vapour can affect the energy balance of the Earth. This happens because they are able to absorb the longwave radiations emitted from the Earth’s surface. The result of this process is the increasing of the amount of the heat energy in the Earth’s climatic system. With no greenhouse effect, the average of the global temperature of the Earth would change from 15 to -18 Celsius.
There are a number of factors that allow scientists to believe that human activity is the source of climate change. Carbon emissions are the main cause of global warming. When human beings burn carbon based fuel like coal and gasoline for energy, the carbon dioxide they release is lighter than the carbon dioxide from other sources. The level of lighter carbon dioxide has increased drastically in the last 40 years. Another cause of global warming is deforestation.
Fossil fuel energy is slowly killing our planet earth. With fossil fuel use and consumption being so high these days we are slowly but surely warming our Planet’s climate causing: glacial melts, floods, more frequent and severe weather conditions, more acidic oceans, and higher sea levels. All those atrocities are caused by a side effect of fossil fuel use and consumption and it is called global warming. There is a solution to stop global warming and it is called green energy. The name of the solution to global warming is Wind Energy.
