Global Warming Argumentative Essay

Climate change is a serious problem that is happening now and its dangerousness is worsening over time. However, we can avoid it because we are the ones who caused it in the first place beside the natural causes. Therefore, no one else but us can stop it. It is noticed that the term ‘Global Warming’ has been used regularly in media to describe this crisis. However, the appropriate term that should be used is ‘Climate Change’ not ‘Global Warming’ because the first one is more accurate scientifically. Therefore, it is very important to distinguish between the two terms. According to Institute for Global Environmental Strategies and NASA Educational Technology Services, “Global warming refers to the long-term increase in Earth's average temperature.”

First, volcanic eruptions. Carbon dioxide and aerosols, floating solids and liquids around the air and they distribute incoming solar radiation, are released during volcanic eruptions. The aerosols released block some of the sunlight, so they cause a cooling affect that lasts for a year or two. For example, in June 1816, it snowed in the US and Canada due to the the largest eruption in the history, the eruption of Indonesia’s Mount Tambora. That year was known as “Year without summer”. As a result, people suffered from food shortage and the number of mortality increased due to the regional losses of crops. Second, changes in solar radiation. The solar radiation changes by small amount that equals 1.3 W/m2. .There are sunspots on the sun’s surface. The darker the sunspot, the lower temperature it has relatively to the surrounding area. The heat energy moves from the inside part of the sun with the help of the gasses flow. When the sunspots are active, the sun exhale a little bit more radiation, because the sunspots contain the heat and then spread it to the areas around them. Third, crustal plates movements. the movement of tectonic plates can change the climate. As an illustration, oceans have high heat capacity, so they warm slower than landmasses. Because of that, the Northern Hemisphere has been warmer than the North Hemisphere since the Industrial revolution, as the Northern Hemisphere has more landmass (Climate Science Investigation,
