Essay on The Threat of Global Warming - 1667 Words

The Threat of Global Warming Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of the dinosaurs, some 65 billion years ago. If we stay at the rate we are now (fossil fuel consumption / growth in population) then within the next two century the Earths air might not be fit to breath. Many†¦show more content†¦These gases are carbon dioxide, methane, ozone, nitrous oxide, and water vapor. The main contributor to the greenhouse effect and global warming is carbon dioxide. The atmosphere contains over 700 billion tons of carbon in the form of carbon dioxide. Currently, humans burn more than 5 billion tons of fossil fuel carbon each year, all of it going into the atmosphere in the form of carbon dioxide or carbon monoxide. In addition, deforestation and subsequent burning and decay add another 1.5 billion tons. Scientists feel that about 40 percent of the carbon dioxide released into the atmosphere is taken up by the oceans or plant growth. The remaining 60 percent stays in the atmosphere, and is responsible for the .4 to .5 percent yearly growth in carbon dioxide concentrations. Methane is also another major greenhouse gas that is growing significantly more and more each year. Methane is a gas that is naturally produced from decomposition of plant material and enteric fermentation in animals. Scientists say that the growth of methane is from a combination of increases in petroleum, natural gas, coal, rice farming, and increases in the population of domestic farm animals throughout the world. Nitrous oxide is just slightly increasing each year due to fossil fuel combustion and soil fertilization. Emissions from fossil fuel combustion also react to form ozone in the troposphere. Ozone acts likeShow MoreRelatedThe Threat Of Global Warming976 Words   |  4 Pagescentury more dramatically than any other, and that is the urgent threat of a changing climate â€Å" ( Barack Obama ). Global warming is the increase of earth’s average surface temperature. The threat has presently widespread over a 50 year timeline. The human race has birthed a disastro us world that is deteriorating every second of the day. It is becoming almost too hard to come back from this catastrophe.

People try to ignore it because they are afraid of what it will cause. They don’t want to accept what scientists are saying, â€Å"Humans are to blame†. I, being a future scientist, also believe that humanity is the cause of global warming. This believe of mine stemmed from a class I took in middle school that put us, students, in the shoes of United Nations members. We had to take sides on issues such as deforestation and the usage of fossil fuelsRead MoreGlobal Warming Is A Threat Essay1533 Words   |  7 PagesGlobal warming has been a controversial issue since the first publication of global warming, â€Å"Worlds in the Making,† by Svante Arrhenius in 1896. This topic is discussed in multiple areas of life, including politics, at the din ner table, and among scientists in a laboratory. The various viewpoints of individuals usually lead to a heated discussion on global warming, and sometimes ignites an intense argument. Through research and discussions with various people, I have come to the belief that globalRead MoreThe Threat Of Global Warming1487 Words   |  6 PagesEver since the twenty-first century, the injury and menace posed by global climate change to human being has long been acknowledged by public. In the face of global warming, a series of resulting problems inflict a serious threat on the nature environment, which is the material base of the human being depending on. Therefore, climate change is no longer just a discipline problem but also has gradually become a major social problem, which has draw a common concern for us humans.
