A. Attention Getter – The uninhabitable Earth, is what we`ll soon be called. Anticipating what the exact effects will be on mankind and other living organisms on planet Earth is tricky, however, a continuously growing amount of evidence suggest that it will be intense. In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.
B. Establish Credibility – After significant research on this topic, I am more than qualified to prove to you why humans are the main cause of climate change.
C. Audience motivation – If we don’t cut greenhouse gases and other factors contributing to climate change, it won`t just be the storms and rising seas we’d have to worry about. The heat alone could kill off all humanity living on Earth. And yes, that means all of you and as well as myself, dead.
D. Thesis and preview - In this speech, I will discuss the human activities and testify why such activities are the main cause of climate change. First, I will talk about the increase of carbon dioxide in the atmosphere. Second, I will discuss how industrial agriculture damages the Earth`s climate. Finally, I will talk about the depletion of human resources.
(Transition – I will begin by discussing the increase of carbon dioxide into the atmosphere and how humans have made it one of the main causes of climate change.
II. Body of Speech
1. Main Point - Despite the fact that a specific amount of carbon dioxide (CO2) happens naturally in the Earth's atmosphere, there are many human activities that boost the levels of the greenhouse gases causing it to be harmful to Earth`s climate.
A. The Burning of fossil fuels generate 85 percent of electricity worldwide. The generation of electricity is the single largest source of CO2 emissions. Some examples of what this energy is used for are in power plants, cars, planes, and industrial facilities. Almost all industrialized nations get the majority of their electricity from the combustion of fossil fuels (around 60-90%) as well as the
In recent years, global climate change due to global warming has been largely researched. The paper, “Global Climate Change Triggered by Global Warming,” offers compelling evidence from various scientific papers that the process of Earth’s climate undergoing significant change has already begun and requires our attention due to the probability that human-generated greenhouse gases are the primary cause. Major focal points are shifting towards determining the causes to mitigate the effects rather than establishing the existence as sufficient amount of evidence has proven that global warming is indisputable. During the final decade of the 20th century, climatologists have concluded that the past millennium to be the warmest, especially in the year of 2005. Solutions towards the cause would require assistance from the population as a whole.
The result is that humans are adding ever-increasing amounts of extra carbon dioxide into the atmosphere. Because of this, atmospheric carbon dioxide concentrations are higher today than they have been over the last half-million years or longer.
Disruptive climate changes are a result of our actions. From 280 molecules of carbon dioxide in 1750 to a 384 presently is due to the rapid Industrial Revolution. The readers are convinced to an extent of the alarming increase of carbon dioxide levels in the atmosphere. These facts should help to galvanize people, governments, organizations and individuals to work on a better environment. My ideas about such a circumstance do not change because we humans are the cause of this depleting environment. Through discussions it was observed how globalization has greater negative than positive
The importance of climate change, which is always debatable, has now become more controversial. It is believed that climate change has serveral negative impacts, thus it needs to be studied. As far as I am concerned, I strongly concur with the argument that causes and solutions need to be investigated. This article will elaborate the antropogenic impacts and potential solutions and thus lead to a logical conclusion.
Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around 389 parts per million (ppm) as of September 2011,
Humans are pouring carbon dioxide into the atmosphere at a much faster rate than the rate at which plants and oceans can absorb it. Global warming is the increase in the overall temperature of the Earth 's atmosphere; global warming is a delicate topic because it is happening right now no one can stop it from happening. It is already transforming life on Earth, shifting the seasons, raising the temperature and rising the sea level. Other effects of global warming include stronger storms, extinction of species, rapid disappearance of Artic ice, and the increase of the ozone hole. It became an issue in 1988 when a scientist from NASA found that "Global warming has reached a level such that we can ascribe with a high degree of confidence a cause and effect relationship between the greenhouse effect and observed warming" (Hansen). James E. Hansen testimony was a big thing that everyone start to worry about it and everyone was talking about global warming because the media contribute to it. Global warming is a big thing happening right now but we don’t listen to others and we continue with our life’s without looking around us and without helping to stop the cause of it because as a humans we make errors during life but we learn from the errors and the bad choices. Although some people believe mankind is not responsible for global warming, it is a serious problem worldwide and measures are need to help slow the problem.
Due to human activities, carbon dioxide in the atmosphere has risen extensively since the Industrial Revolution and has now reached dangerous levels not seen in the last three million years. Humans impact climate change every second whether they are, burning fossil fuels and impacting the layers of the earth..
The article “The Struggle of Our Time: Human Nature vs. Mother Nature” explains the causes and effects, as well as the steps to counteract climate change. Moisés Naím associated the humanity’s effort to reduce climate change with an individual’s effort to lose weight. Naím stated that people who are on a diet tends to give up before achieving their goal, and goes back to their old ways of eating. The author has indicated that the same thing happens to the humanity’s effort to reduce climate change. Moisés Naím pointed out the effects of climate change in this year. He affirmed that this year is the “hottest on record.” In addition, the strongest hurricane ever recorded was experienced this year. Moreover, the author mentioned that climate change is caused by human activities: transportations, how our cities were built, products we consume, how we heat/
Every year, almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gasses, carbon dioxide and methane primarily, in the earth's upper atmosphere directly caused by human burning of fossil fuels, industrial, farming, and deforestation activities. Global warming is defined as an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic
• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes
In addition, human activities like deforestation may increase the amount of carbon dioxide in the atmosphere. This is because forests help in carbon sequestration, which reduces the amount of carbon dioxide in the air. It follows then that clearing such tress will increase the amount of carbon dioxide since carbon sequestration will not occur (3). The man-made theory of climate change also explains that when these harmful gasses reach the atmosphere, they form a blanket, which traps heat in the atmosphere. This trapping of in the atmosphere is the phenomenon that causes the planet to get warmer, hence the term global warming (Sharma, 4).
Credibility Position (Why you picked this topic): After I read this particular article, it made me realize that the global warming was taking pace at a rapid speed than I had imagined. Its impact was certainly happening quickly than I expected. Then, I did some research to find out its problems and also I looked at solutions to minimize the impact of global warming.
In recent years, the controversial subject of global warming has been more predominantly brought to our attention. Is the threat of global warming real? Is it man-made or is this just a natural cycle of earth? Does it really affect earth’s inhabitants? Should action be taken against it? If so, what kind and to what extent? It cannot be only a coincidence that the alarmingly rapid climate change coincides perfectly with the increased amount of pollutants that humans release into the environment. The once stable climate has in recent years begun to skyrocket, thus altering the delicate structure of earthly life. This proves to be hazardous to the future of the planet; some people worry that many of the resources the environment provides that
Think of a person riding downhill on a bicycle that has no brake on the wheels, and who knows that there is a large glass plate placed vertically somewhere across the way. The person is sensible enough to predict that if he continues to enjoy this ever accelerating ride, he is going to collide against the invisible glass plate in a short interval. But he is so deeply content on this ride that even after the knowledge of a certain accident ahead unless he jumps out of the bicycle, he is willing to go a bit farther for his personal fulfillment. Today, we face a similar situation in which we are seemingly unwilling to help ourselves out of a possibly disastrous problem of global temperature rise.
Climate change. A phrase that encompasses a vast wealth of information, the totality of which is difficult to fathom let alone concisely elaborate upon in a condensed format such as a course or writing assignment. Through this course, the interconnectedness with which humans influence the balance of climate change is abundantly clear. Ecosystems plants and animals depend on are all connected and influencing one another but these scales are imbalanced, mostly as a result of human activities. The web of interconnectivity in climate change is complex, but there is a reemerging consensus at it’s core that human actions, such as global development, has major ramifications and the health and welfare of people and the environment are paying the price. Those daring enough to say they aren’t influencing climate change haven’t truly examined the many facets of their lives consuming energy and in turn increasing carbon emissions that alter climate. For most, transportation is a necessity. This usage requires energy consumption, most likely in the form of fossil fuel resource depletion and in turn the generation of carbon emissions. Transportation routes by land or sea may alter ecosystems that further elevate carbon emissions. With an understanding that the topic of climate change and carbon emissions is massive at best, the aim of this assignment will be to provide the reader with a basic understanding of greenhouse gases and carbon emissions and the relation to climate change.
