The Role of Human Activities in Climate Change and How This Is Driven by a Capitalist Society
Climate is defined as the “average weather” for a particular region. Climate change is the human activities that affect Earth’s climate by using the human activities inappropriately that leads to the warming of the Earth. There are variety of ways that affect Earth’s surface. The enhanced of greenhouse gases is the main reason why the Earth’s climate is constantly changing because releasing an abundant amount of gases through human activities, deforestation.
The greenhouse effect is the process by which absorption and discharge of infrared radiation by gases in the atmosphere warm the earth’s atmosphere and surface. The major greenhouse gases are water vapor, carbon dioxide (CO2), methane (CH4), and ozone (O3), Clouds also affect the radiation balance, but they are composed of liquid water or ice and so are considered separately from water vapor and other gases. According to the Intergovernmental Panel on climate change, in 2001, the human activity had played an important role in global warming. The main reason of warming due to human activities is due to the burning of fossils fuels and rapid industrialization. Since the Industrial era the amount of greenhouse gases has increased in the atmosphere, leading to increased radioactive radiations produced from carbon dioxide, methane. The concentrations of carbon dioxide and methane have increased rapidly. Fossil fuel burning has produced a noticeable increase in carbon dioxide from human activity over the past years. And the other major reason for increase in global warming is due to land-use change, particularly deforestation. However, because of the increasing demand of raw materials for houses and other uses for example – wood and paper pulp, industries tend to cut down more trees. Therefore, the enormous change in the rate of temperature is due to the industrial revolution.
According to Milbourn (2009), use of fossil fuels accounts for 80-85% of carbon dioxide in the atmosphere currently. Deforestation that is, cutting down of trees also contributes to increase of greenhouse gases in the atmosphere. When man cut trees down and burns them, the carbon that is contained in trees is released into the air as carbon dioxide. Other human activities include farming; the use of fertilizers and other chemicals in farming releases nitrous oxide, which is a hazardous gas that causes about 10% of air pollution (Cynthia & Daniel, 1995). Changes due to land use accounts for 15-20% of the current carbon dioxide emissions in the atmosphere (Milbourn, 2009).
If the earth’s temperatures continue to rise in the future, living things on earth would become extinct due to the high temperatures. If humans contribute to control global warming, this world would be cooler and the high temperatures we currently have would decrease. If everybody as one take stand and try to end most of the climate changes that are occurring, this world would be a safer place to live on.
