Global Warming There is no issue quite like global warming. A strong consensus exists among scientists that Earth is warming up at an alarming rate. Natural processes are involved, but most of the warming is caused by human activities, especially the burning of fossil fuels, mainly coal and oil. If something is not done and done soon — within the next decade or two — we will face a long list of troubles that would affect our surrounding environment. What is Global Warming? What caused it? What is its impact? How to stop it from happening? These are the main questions that need to be focused on when we analyze this issue. So first, what is Global Warming? It is the Earth’s gradual increase in the overall temperature of the atmosphere generally attributed to the greenhouse effect. In an easier way to understand, global warming is a negative change in the Earth’s climate, temperature and environment. What caused Global Warming? It is caused by the increased levels of greenhouse gases including carbon dioxide, chlorofluorocarbons, methane, nitrous oxide and other pollutants. Even though the Earth would be a very cold place if it were not for greenhouse gases trapping heat in the atmosphere, they present too much that it went way over the amount of needed gases to maintain a balanceable temperature on the Earth atmosphere. So instead of protecting the Earth from coldness like before, the greenhouse effect is now considering life endangerment. So, what caused the level of carbon dioxide and other pollutants to increase? The answer would be natural causes if we happen to live in the Stone Age, but this is the twenty-first century and human is the one and only threat to the environment. During the Industrial Age, the growth of factories like coal factories produce Carbon Dioxide and other greenhouse gases as waste products as they burn fossil fuels. When they release all of the wastes out, the overloaded gases would then trap a large amount of heat and light from the Sun in the Earth’s atmosphere causing climate change and global warming. Unfortunately, Coal is the main resource to generate electricity in the United States, so therefore to eliminate all of the Coal factories would be impossible, but we can think of some better ways to keep the burning of fossil fuels cleaner by wasting all of the greenhouse gases under the ground, or we can think of using more of the other resources to generate electricity like wind energy or solar energy.
Transportation is another big cause of global warming. Because of its near-total dependence on petroleum fuels, the U.S. transportation sector is responsible for about a third of the country’s climate-changing emissions. Globally, about fifteen percent of manmade carbon dioxide comes from cars, trucks, airplanes, ships and other vehicles. Cars, trucks and sport vehicles are to blame for about two-thirds of greenhouse gas emissions from the U.S. transportation sector. As more vehicles hit the roads, the pollution will increase dramatically unless we create strict policies for petroleum fuels cars-reduction. Instead of using petroleum fuels, we should apply natural gas because it emits fifty percent less carbon dioxide than coal and petroleum fuels when you burn it, or we can apply electricity because it is a renewable resources and it doesn’t have to be burned to produce energy. Fortunately, fossil fuels will come to a shortage by the year of 2050, car industries all over the world are working on producing electricity car models for future use.
Deforestation, permanent destruction of forests in order to make the land available for other uses, is considered to be one of the contributing factors to global climate change. As we have learned this from Biology, trees absorb greenhouse gases (Carbon Dioxide) during the night, then produce Oxygen and perpetuate the water cycle by releasing water vapor into the atmosphere. Without trees,

Global Warming Paper Cameron Conolly For years many people have believed that we are causing the Earth to warm up faster. Global Warming is the heating of the climate. Others believe it is due to natural climate processes. Either way, we know that Global Warming is a serious issue for our Earth. One of the reasons we think Global Warming is occurring is because of Orbital Variations. “Orbital Variations” is part of a theory developed by Milutin Milkankovic. An astonishing fact about Milankovic…

Changes in the sun’s force and the earths’ course around it, along with natural elements such as; erupting volcanos…

GLOBAL WARMING Global warming, also called climate change, has become a topic of concern over the past decade. Climate has changed drastically over the past decade, “From 2001 through Feb, 2011 the atmospheric carbon dioxide increased by 22.2% of the total increase from 1800 to 2001” (Pangburn). Although I wasn’t completely aware of global warming and it’s circumstances until recently, I can honestly say that it is a issue to be concerned about. Global Warming is an indisputable…

GLOBAL WARMING: NATURAL OR MAN-MADE There is no question that there is an increase in Earth’s temperature and we are experiencing what is referred to as global warming. The Earth has experienced this many times in history on a much larger scale, but, humans did not exist (and would not have been able to exist) at the time. The questions now are whether human actions are accelerating the process of global warming and possibly decreasing Earth’s future sustainability; and, if so, what, if anything…

What Are the Causes of Global Warming? What is global warming? According to NASA Earth Observatory, global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed…

Global warming is the gradual heating of Earth's surface, oceans, and atmosphere. According to the Environmental Protection Agency, “Earth's average temperature has risen by 1.4 degrees Fahrenheit over the past century.” Sadly enough, “temperatures are projected to rise another 2 to 11.5 degrees Fahrenheit over the next 100 years.” As a consequence, global warming has emerged to have one of the biggest environmental issues in the last two decades. For the past years, scientists have been struggling…

Global Warming: Rodriguez Tony P.3 Global warming is caused primarily by carbon dioxide from burning coal, oil and gas. Certain gases that trap heat are building up in Earth's atmosphere. The primary culprit is carbon dioxide, released from burning coal, oil and natural gas in power plants, cars, factories, etc. (and to a lesser extent when forests are cleared). The second is methane, released from rice paddies, both ends of cows, rotting garbage in landfills, mining operations…

Global Warming Essay

endless debate going on about global warming. Some people say that global warming is a threat to us socially, economically, politically, and immediate actions should be taken to minimize it. Whereas, other people say that global warming is beneficial and is a natural process that is required for the sustainability of life on earth. Hence, in my opinion, global warming is a potential threat that causes harm not only to humans, but also to the planet as a whole. Global warming can be defined as the increase…

Global Warming. Is it caused by us? “…Climate change is now with us. It will not go away.”(Musil, 17) Many of us have noticed that our Earth is getting warmer. We seem to ignore what is going on and just continue with our everyday life. There is evidence that our climate has been getting warmer ever year. Some scientist believe it is because of green house gases. Green house gases include the carbon dioxide from gases that our industry produces, methane gases that cows put off, and some believe…
