Climate change has been a major concern for all nations of the world for centuries. Climate change refers to changes in weather patterns that can be indicated through global warming, natural disasters, and rising sea levels. There is a group of climate change skeptics who argue that climate change is not the result of human activity, which means it happened naturally. According to Slaght, this refers to internal factors, such as the interaction between the atmosphere and the ocean, and external factors, such as variations in solar energy and volcanic eruption (John Slaght, 2009). However, most scientists argue that humans are also involved in this process. Accordingly, this essay aims to discuss the impacts of greenhouse gases on the climate, then the human contribution to climate change and, finally, some statistics on the effects of global warming. Global warming is commonly caused by excessive amounts of greenhouse gases. Greenhouse gases are gases that work in the same way as the greenhouse effect, absorbing thermal radiation from the Sun and re-emitting it to the Earth's surface. This process is called the greenhouse effect. Additionally, greenhouse gases include carbon dioxide, nitrous oxide, water vapor, methane, and chlorofluorocarbons or commonly called CFCs. According to Steffen, “The main cause of the observed changes in the Earth's climate are human activities, mainly the burning of fossil fuels” (Steffen, 2013). The process of burning fossil fuels releases a huge amount of greenhouse gases into the atmosphere, particularly carbon dioxide, disturbing the balance of greenhouse gases in nature. As stated by Slaght, “The accumulation of greenhouse gases in the atmosphere due to human activities will change half the paper and replace it with little or no regrowing vegetation. It takes years to regrow the lost vegetation. To summarize, it is obvious that climate change has indeed occurred. Humans are considered the main cause of the problem as the use of fossil fuels and deforestation are disrupting the climate the natural balance of greenhouse gases. Global warming has long-term effects on our lives. It is a serious concern that actions must be taken immediately before it is too late. Works Cited John Slaght, PH (2009).
