Carbon dioxide is naturally present in the atmosphere as part of the Earth 's carbon cycle. Yet human-related emissions are responsible for the increase in CO2 emissions. The use of electricity accounts for 37% of total U.S. emissions, while transportation 31%, industry accounts for 15%, residential and commercial 10%, and other non-fossil fuel combustion 6%. That is 99% of the total globe greenhouse gas emissions. Carbon dioxide (CO2) emissions in the United States increased by about 7% between 1990 and 2013. (EPA, 2015) Not leaving out pollution also a contributor of increases in anthropogenic CO2. These things are the cause of the earth heating up, or global warming. Trees and plants help soak up the CO2 in the atmosphere but with the tearing down of trees to build industry buildings, residential and commercial buildings there are fewer trees and plants to take in CO2 for photosynthesis.…
Carbon Dioxide (CO2), a chemical made up of one carbon atom and two oxygen atoms, is a non-flammable, odorless and colorless gas that exists naturally in the atmosphere. CO2 is one of the greenhouse gases, amongst methane, nitrous oxide and other gases, which keeps the Earth’s temperature habitable (UCAR). Without it, the Earth will be inhospitably cold. However, ever since the mid-nineteenths century, humans have significantly increased the amount of CO2 emitted into the atmosphere, creating an imbalance. The gradual increase in CO2 concentration have been driving what is called global warming, which describes the current phenomenon of the increase in temperature of the Earth's surface and…
The idea of climate change, for many, is an opinionated subject with much discussion of whether it is a real issue or just a natural phenomenon. However in recent years it is clear to see that trends in the Earth’s climate and surface temperature has spiked to levels never seen before. Despite all the evidence of the high levels of greenhouses gases and the rise in temperature, many still believe that there is no connection between the two, and that the Earth is just going through its natural cycle.…
According to the United States Environmental Protection Agency (“EPA”), the increase in anthropogenic CO2 emissions has led to the increase in global temperatures in the past century . Because of the preponderance of evidence linking greenhouse gases and climate change, governments worldwide are developing policy to reduce CO2 emissions.…
Notable author, educator, and environmentalist, Bill McKibben, in his essay, “Global Warming: Get Up! Stand Up!”, argues the effects on global warming to the environment. He argues from his environmentalist experience that carbon dioxide is not only harming the ozone layer. McKibben’s purpose it to persuade readers to stand up for what they need and start a movement. He takes a defensive tone in order to inform the minds of his readers. In McKibben’s article “Global Warming: Get Up! Stand Up!” states the growing problem of global warming and urges readers to start a movement to end the problem.…
There is evidence that global warming is becoming worse primarily due to rise in carbon dioxide concentration in the atmosphere. In 1950s, the concentration of carbon dioxide was at 315 parts per million. Currently, the concentration is about 385 parts per million. To discover an increase in concentration of carbon dioxide throughout history, scientists have used bubbles of air trapped in ice and results show that the current concentration of carbon dioxide is the highest and has been, for more than 10,000 years (Maslin, 2007).…
Does the high level of Carbon Dioxide (C02) possibly harm the Earth’s planetary biosphere, or has it already done so; in fact, many worldwide scientists have protested that the Earth is at its ‘tipping point’ but no efforts have been adapted to save the biosphere? A support of this controversial topic; congressional meeting and testimony, is from one of the top U.S. climate scientists, James Hansen to Former Vice President Al Gore, with an emphasis on the cause of C02. Beyond the ozone layer is atmospherically holey, Earth’s temperature is rising, and the climate changing conversely, one that people trivialized the most is: Global warming. Increasingly, subject to concern not only via online discussion, magazine and article but also part of the agenda at the Whitehouse, “We can’t have an energy strategy for the last century that traps us in the past. We need an energy strategy for the future – an all-of-the-above strategy for the 21st century that develops every source of American-made energy,” said, President Barack Obama. Is global warming a major concern when the world is economically depending on the burning of fossil fuels? Is the world merely a tumbled target, yet again, to politically afflict and advertise? All the same, The Whitehouse makes no solid effort in claiming that U.S. and the Earth is facing vulnerability, if the burning of fossil fuel is not imposed immediately. Despite all these controversial discussions, scientists have shown that global warming is at its tipping point, C02 level are historically rising and temperatures are getting hotter because humans continue disregard its actions.…
Controversy over global warming exists as a dispute regarding the nature and consequences of global warming. The theory of global warning as presented in the mainstream media currently assumes that carbon dioxide is an atmospheric greenhouse gas and since humans are producing more carbon dioxide than previously, the temperature must therefore rise. The cause of global warming is not actually known, but in it 's simplest terms the debate boils down to whether or not global warming is caused by human interference or part of a naturally occurring cycle. The debate has recently become one-sided in favor of human interference due mostly to three factors: political pressure on scientists to produce research that supports the global warming theory, public misconception of what scientific consensus is, and an irresponsible that media promotes sensationalized viewpoints to sell advertising.…
Along with many other problems, global warming has become one of the top issues in the world. As the consequence of emitting carbon dioxide, the world’s temperature has risen from the past. Despite the fact that there is statistical evidence, there have been controversies as in how much effort should be put in to solve the issue of global warming.…
3. The gold-salt trade develop between West Africa and North Africa because first of all they were lucky because they had camels to travel on. Well, the gold-salt trade develop between West Africa and North Africa when the Berber-speaking people began crossing the Sahara desert. From the eighth century and onward, annual trade caravans followed routes. So that is how the gold-salt trade develop between West Africa and North Africa.…
Since the inception of planet earth, the sun has heated the planet. As earth cooled and an atmosphere developed, it provided a protective shell that allowed microscopic creatures and plant life to grow. As the species on earth diversified, plants began to absorb carbon dioxide and provided oxygen that was needed for animal life. In turn animals exhaled carbon dioxide for plant life. Over time, a complex symbiotic relationship developed between the earth’s weather, chemical elements, and living organisms. This balance has, for the most part, helped keep the global temperatures relatively constant. However, there are at least five times that global temperatures drastically changed resulting in the mass extinction of a good portion of the species living at that time. These were caused by natural occurring events such as extreme volcanic activity or an impact of a large asteroid on the earth. Now however, some scientist are questioning where or not human activities that produce large amounts of carbon dioxide will lead to extreme changes in climate and another mass extinction event. While the debate rages on, the earth continues to warm. Furthermore, very little has been done to address the issue as inaction continues to be the norm. And even though global warming is a natural phenomenon, there is evidence that human actions are exacerbating the problem to a point that it could ultimately lead to a collapse of the environment and the biodiversity of the planet, to include the possible elimination of the human race. Therefore, if there is even a possibility that human actions are contributing to global warming, the world should do everything it can to mitigate our carbon footprint.…
Anthropogenic climate change is an establishment phenomenon. Within the scientific community, the question is no longer whether climate change will occur, but at what rate, with what effects, and what, if anything, we can do about it. The biggest culprit in climate change is an increase in atmospheric carbon dioxide, which is generated primarily through burning fossils. Earth’s average temperature is based on daily measurements taken at several thousand land based meteorological stations around the world, as well as data from weather balloons, orbiting satellites, transoceanic ships, and hundreds of sea surface buoys with temperature sensors. Scientists around the world have researched global climate change for several decades. As the evidence has accumulated, the most qualified to address the issue have concluded that temperatures have increased over the past century, that it is extremely unlikely that natural causes can explain the warming, and the human produced greenhouse gases are the plausible explanation for the warming that has occurred.…
Global warming is an epidemic in today’s world referring to the escalation of the average annual temperature. It brings with it a widespread ongoing debate about whether or not the Earth’s temperature is growing due to the emission of gasses from burning fossil fuels. There have been numerous debates, movies, and books on the rising pandemic. It may not seem to affect the world now, but, if true, global warming could cause a serious demise in the quality and quantity of human life. Many people are doubtful when it comes to the idea of the earth gradually moving towards its end, but this issue does not need to be left in the dark.…
In the reading ‘Global Warming” by Jill Egan the author explain how the Carbon Dioxide(CO2) is setting a layer on the atmosphere that is blocking the heats waves to get out, causing a global warming alert that could destroy a million kinds of plants and animals by the year 2050. According to studies, about 20 percent of the Earth's land area could be affected by this phenomenon .…
The average global temperature has historically varied significantly creating periods of cooling (¡¥ice-ages¡¦) and warming. Evidence shows that the world¡¦s climate is warming. Africa¡¦s climate has warmed by about 0.5aC during the 20th century (Nkomo, Nyong & Lulindwa, 2006). The debate over if climate change is caused by humans or not is beyond the scope of this document, however it has been shown historically that there is a direct correlation between CO2 levels and global temperature (see Appendix 1). The Stern Review on the Economics of Climate Change (2006) argues that urgent action needs to be taken to stabilise the CO2 levels in the atmosphere. At current CO2 output, this could result in a 2aC increase in average global temperature by 2050.…
