Does Human Activity Influence Global Climate Change? Global climate change is the gradual increase in the overall temperature of the atmosphere of the Earth. It is caused by carbon dioxide, chlorofluorocarbons, and other pollutants. The biggest contributor to global climate change are greenhouse gases (gases that trap heat in the atmosphere) such as carbon dioxide, methane, and nitrous oxide. An unnaturally large amount of these “greenhouse gases” are released by human activities like burning fossil fuels, deforestation, and mining. These human activities are responsible for global climate change. It isn’t a result of natural causes. The largest source of greenhouse gases is the burning of fossil fuels. Automobiles and energy production use fossil fuels. The burning of fossil fuels release carbon dioxide into the air. Carbon dioxide absorbs infrared energy that is emitted from the Earth and prevents it from being sent into space. The infrared energy is trapped in the atmosphere and heats the Earth. In a year 21.3 billion tonnes of carbon dioxide is produced. Only half of it is removed by natural processes while the other half remains in the atmosphere. The amount of carbon dioxides in the air has rapidly increased as the human population has also increased rapidly. As the population increases more automobiles and energy are needed thus, the level of carbon dioxide in the atmosphere increases. the second cause of global climate change is fluorocarbons. Fluorocarbons are man-made chemicals used in refrigerants, solvents, and anesthetics. These chemicals contribute to the greenhouse effect, warming the Earth. The amount of these gases in the atmosphere and their atmospheric concentration is lower than carbon dioxide but, they are a lot more potent. Even though the use of fluorocarbons has been phased out, they still exist inside of older equipment.
