The Global Warming Debate We are polluting the atmosphere and with an increasingly wide range of polluting substances and these are due to the fact that there are now so many people and their human activities are altering the chemical compositing of the atmosphere through the buildup of gases. By the end of this article, you will start to wonder about what this is doing to our world. What is global warming? Global warming takes place because human activities are pumping vast amounts of gases. These are Carbon dioxide – this gas is unconfined to the atmosphere when solid fuels such as oil, natural gas and coal, and wood products are burned Methane – this gas is given out during the production and transfer of fossil fuels. It also results in the decomposition of organic wastes in solid waste landfills and the raising of livestock. Nitrous acid – this is released during such things as industrial activities and the burning of waste and once again fossil fuels. These are also known as greenhouse gases. They produce the greenhouse effect. This takes place because these gases are trapping more and more of the heat given off from the Earths surface which then escapes into outer space. This then makes the atmosphere and the Earths surface much warmer – like a greenhouse whose glass walls and roof trap heat from the Sun. Carbon dioxide is dangerous in controlling the Earths balance in heat because it takes in infrared radiation. As a result of this, we are growing up in a world much warmer that it was than the 20th century because of the increase of greenhouse gases. Without these greenhouse gases however, the Earth woul... ... middle of paper ... ...ing global warming being an even more major factor than it is now. You can send a message to your elected officials, letting them know that you will hold them accountable for what they do – or fail to do about global warming. You can also drive less by choosing alternatives such as public transport walking or even riding a bike. Also, learn to bundle all your errands together so trips will be reduced. Also you can choose to replace your light bulbs with compact fluorescent bulbs. This is because they last ten times larger than incandescent bulbs. They will also lower energy bills and will keep carbon dioxide out of the air. You can also consider joining such action group’s who try and secure the changes that will stop global warming.

Finally, the moment you have all been waiting for, the third paragraph! This is where I will persuade you to believe my ideas. Well, here it goes. My final idea is that the globe is now recovering from a time know as the little ice age. This in turn will make the earth seem warmer. In science class, we conducted an experiment conducting this. We put one hand in warm water and another in cold water. Then we put both hands in room temperature water. The hand that was in warm water felt cold and visa vera for the other.
For a significant number of years it has been evident that global temperatures were rising and that human activity is a major contributing factor to this rise. The rise in temperature is not only heating the planet but having an adverse effect on the global climate.

Global warming, by definition is the “ gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.”(Webster) In the last several decades, there have been numerous debates regarding global warming. As of now it has become one of the biggest problems facing the world today. Scientists do believe that our production of greenhouse gases and carbon dioxide is having a warming effect on the atmosphere, but it also is creating a positive impact to on the planet. The controversial side is scientific consensus that it is the fault of mankind that our actions have led to the results of earthquakes, tidal waves, geographical plates moving, all because of global warming pollution. The other side that is also debated on is that global warming can bring new developments to our planet and to all that dwell within. In this paper I will examine the positive and negative side of global warming and suggest some ways nature and humans are solving the issue. Global warming is causing the largest impact to nature and humanity in the 21st century, but with green house gases on the rise, humanity, nature, and species will learn to evolve.
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
Global warming is a topic that is constantly disregarded because the issue seems to small and irrelevant. However, people do not realize that global warming is time sensitive. Over the last 30 years, there has been an average increase of 1.5 Fahrenheit per year. Global warming has significantly gotten worse often the past years and there seems to be little to no action to prevent global warming. Through the increase in carbon dioxide levels and deforestation, it is evident that global warming is affecting us dramatically, suggesting that if we do not take action soon, we will be unable to live in such living conditions.
Climate models play a big role in the global warming debate, and the majority of them show rapid warming. However, those same models that are showing rapid warming in both short and long-term periods are already too warm. Over the last 100 years, the earth has warmed by about 0.7° Celsius, which is about three or four times less than climate models were saying there would be 10 years ago. Dr. Roy Spencer, a climatologist, once stated, “In fact, thermometer measurements from the 1930s indicate that temperatures were just as warm now as they were back then.” Since the 1930s, earth has undergone short periods of both warming and cooling, which can correlate with past geological times where temperatures have continued to fluctuate. Since the period of warming we have measured in the last 100 years is so short compared to the past, it is tough to draw conclusions on whether humans have an effect on the speed of warming or not. Climate models also have drawbacks, which can’t be solved by the model directly, called positive feedback. Positive feedback can occur when the warming of the earth is amplified...
As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have
Because the Earth is slowly warming up, heat waves, for example, have been occurring more frequently and for longer durations. According to the Climate Communications, “In 2010, 19 countries set new all-time record high temperatures, but not a single country set a new all-time record…” (Overview). Comparing this to Gore’s speech, eighteen countries have experienced all new highs in heat since the European heat wave in 2003. This increase in temperature is due to the shifting of the climates in specific regions as an after effect of global warming.
Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.
These changes are becoming more prevalent in our world today, in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2, “The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed.
Global Warming One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”).
While critical of global warming alarmism, this documentary does not doubt that the earth is warming. Instead, they claim that scientific evidence demonstrates that such warming is but a natural variation in earth’s climatic history, similar to the Medieval Warm Period of the Little Ice Age. The documentary uses several lines of evidence to back up this claim, including ice core data that they claim when rightly interpreted shows carbon dioxide as having a lag time when earth’s climate has warmed in the recent and distant past, making it doubtful that it could be responsible for the increase in temperature that has been observed recently. The timing of the recent warming, which was most pronounced in the late Nineteenth Century through World War II, stopped and reversed to a cooling trend in the mid-Twentieth Century, and then rapidly warmed again in the past three decades, is dissected. Since this warming began before the advent of major human sources of greenhouse gas emissions and the period of most dramatic industrial...
