Each year, over 7.2 billion tonnes of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 110 million airplanes all being in the air at once! These disturbing numbers are the foremost cause of global warming, and have been steadily growing over the past few decades. Global warming is caused by this recent surge of greenhouse gasses which consists primarily of carbon dioxide.
Carbon dioxide isn’t harmful to the atmosphere in the amount that is produced naturally from decaying trees, volcanic eruptions, etc., because the forests act as a natural recycling system. However, humans burning fossil fuels, demolishing forests, and using chemical fertilizers are causing an enormous surplus of carbon dioxide. They are damaging the environment by creating what will soon be, if not already is, an irreversible carbon footprint with no regard to the consequences.
Many people around the world argue regarding the facts about global warming, or if global warming even exists. However, evidence that supports global warming is plentiful with many credible organizations backing it, for instance, NASA has stated that “nine of the 10 warmest years have all occurred since 2000” (“Humans…” n.pag.). Furthermore, over the course of the last century, the total atmospheric temperature has risen 1.1 °F (“Global…” 15571), Greenland has warmed roughly 3.5 °F, and the North Atlantic Ocean has had the warmest water in at least 2,000 years (“Warming…” n.pag.)! Even with all facts proving that global warming is real and a danger to our world, many people still deny its existence.
As stated previously, carbon dioxide in its natural form isn’t harmful to the atmosphere, and many critics state that the carbon dioxide doesn’t affect the atmosphere. However, carbon dioxide couldn’t possibly play a larger role in the stability of the atmosphere. The core purpose of carbon dioxide existing in the atmosphere is to trap the heat acquired from sunlight and not let it past the atmosphere. It’s because of the carbon dioxide in the atmosphere that Earth's
atmosphere is warm enough to sustain human life. When there is a large increase in the proportion of carbon dioxide in the air, the quantity of heat caught by the carbon dioxide also increases. This in turn contributes to the total rise in the surface temperature of the earth. Due to this rise in temperature in ice in the Arctic is melting, which is causing the sea level to rise.
Dr. Leonard Berry from the FAU Climate Change Initiative stated that “The ocean has risen six inches over the course of the last twenty-five years” (“Water…” n.pag.).
A major contributor to global warming is fossil fuels. Fossil fuels are used for everything from generating electricity from turbines to powering vehicles. In the last few centuries the economy has been growing so rapidly that the need for energy from fossil fuels has reached new heights. Upon the burning of fossil fuels, numerous...
