The United States should not take aggressive and immediate action to show global warming. Any environmental change should have both positive benefits and negative effects. For example, theory predicts and observations confirm that human-induced warming takes place primarily in winter, lengthening the growing season. Satellite measurements now show that the planet is greener than it was before it warmed. There were two periods of global warming in the last century. The first ended around 1940 and was caused by the sun's warming up. Temperatures then cooled slightly, until the early 1970's, before warming again. In the first warming, 45 percent of Kilimanjaro's ice cap disappeared. When the planet subsequently cooled, it lost another 21 percent. In the recent warming, another 12 percent has gone, the slowest rate of loss in the last 100 years. Some 4,000 to 7,000 years ago, the earth was a degree or two warmer than it is today, and yet Kilimanjaro's glaciers were greatly expanded compared to the current era.
Bullet point: 1. Comparing to the present and the past, the geological history records the temperature in around 26 degrees Celsius/80 degrees Fahrenheit is the prosperous time of biology, therefore global warming can lead the ecosystem more stable. 2. Global warming is causing the global temperature increase, it extents the range of crops. In addition, it makes the density of carbon dioxide is higher, and the water vapor in air will increase. Therefore, global warming is good for the agricultural development. 3. People who died in the cold wave is more than died heat wave
Counterpoint:
1. For the past decade, the average of global temperature was fluctuating in 0.6 degree Celsius, it is a normal phenomenon. 2. The main reason of global warming is the solar radiation is increasing, but the affects for the humanity is…...

Miranda Warnings

...U.S. Constitution – The Miranda Warning Technically, The Miranda Warning is not in the U.S. Constitution. The Miranda Warning came about after Miranda vs. Arizona in 1966. But it refers to the Fifth Amendment right that protects against self-incrimination, or "the right to remain silent". (Cornell) Amendment V “No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a grand jury, except in cases arising in the land or naval forces, or in the militia, when in actual service in time of war or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.” (Mount 2010) Basically, the 5th amendment is to protect people in situations from getting in trouble it even protects ignorant suspects from incriminating themselves. In particular, it stops you from having to speak to the police or testify against yourself before a court, so it is best to keep your mouth shut until you have a lawyer. It also says that the government has to have a reason for arresting you and that you have the right to a trial with a jury, that you cannot be charged with capital a crime (murder) without a Grand Jury's permission, except in cases when you’re in the......

Global Warning

...Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming. The 29th century is experiencing a continued increase of Earth’s mean atmospheric temperature by about 1.4 degrees F and about two thirds of it occurring since 1980. This is global warming is affecting the nature’s balance and has a huge impact on life like continued heat waves, and sudden occurrence of storms and floods. Don’t we see time to time the epidemics that are devastating to human life and the flooding of the farmlands that puts economy in a deep hole? Scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from non -stop burning of fossil fuels and the razing of tropical forests. Since the industrial revolution till this day, there is a constant emission of the carbon into the atmosphere, everything we do we leave carbon footprints. It is a man made cause of the global warming. The global emissions jumped 3 percent in 2011 and are expected to jump another 2.6 percent in 2012, researchers reported. The greenhouse effect is a process by which the greenhouse gases absorb thermal radiation; these are then reradiated in all directions. But when some of these radiations come back to the surface and lower......

Global Warning

...GLOBAL WARMING The Ozone Layer absorbs ultraviolet radiation from the sun protecting all living organisms below from the dangerous radiation. The Ozone Hole is an area of weakness or depletion in the protective cover of the Ozone Layer over the North and South Pole. Scientist discovered in the 1980’s that the ozone layer was thinning at an alarming rate. This phenomenon was caused by chemicals that came from spray cans and refrigerants or in other words, CFC’s (chemical compounds with chlorine and fluorine attached to a carbon0. These chemicals can remain in our atmosphere for decades breaking down our ozone layer. The people, animals and plants that live under the weakening of the ozone layer have an increased chance of radiation poisoning from the sun where it reaches the surface of the earth and can cause eye damage and skin damage, etc. The Ozone Hole is not the cause of Global Warming. The radiation from the sun only accounts for 1% of the energy from the sun and not enough to cause an increase in heat. The increase in temperature comes from the release of too much carbon into our atmosphere from coal, gas and oil burned to generate electricity or to fuel our cars and planes. These gases spread around the Earth like a blanket, capturing the solar heat that is supposed to radiate out into space. It is the reverse of a Volcano that erupts and sends out ash into the atmosphere. This ash can reflect the solar hear away from the surface causing temperatures to plummet.......

Warning, Analysis, Interpretation

...This is my simple version of the Analysis of the Text "Warning by Terry McCarthy. In this essay, I will be presenting the text called “Warning” written by Terry McCarthy, and show you my analysis and interpretation of said text. Described in broad strokes, this is a text about a school shooting in the town of Santee, committed by the kid, Charles Andy Williams. I am going to tackle this with a focus on the lack of documentation and the journalist and her relation to the text. - The article primarily focuses on the background and previous events that led up to the tragedy, but we do get a brief description of the events at Santana High March 5, 2001. At 9:20 a.m., Andy took out a .22 caliber revolver and shot into a bathroom and a courtyard. He kept firing and reloading for 6 minutes, and 30 rounds were discharged before the local sheriff’s deputies cornered Andy Williams in the boys bathroom, where he finally handed over his gun. - The article plants its focus on Williams’ background, friends and general environment. Terry McCarthy interviewed Williams’ associates, and found that his schoolmates bullied him. It is indicated that the bullying and taunting could be a major cause behind the shooting, and it probably also is. An example of the bullying is mentioned in the article, where Williams was burned with the heated metal from a lighter. He moved to Santee less than 2 years earlier with his father, while his mother stayed in Maryland, where his previous home is......

A Skeptic's View of Global Warming

...April 2010 A Skeptic’s View of Global Warming Is global warming really happening? Is it something that we should truly fear, and if so, why? Scientists and other climate experts have been trying to answer these important questions and many others concerning global climate change for decades. Before one can truly delve into the details of global warming, it is important to define the concept. The entire study of climate change is difficult to explain, and is not yet fully understood by scientists. However, global warming can be simply described as the process of the earth’s atmosphere increasing in temperature due to the presence of greenhouse gases, which include carbon dioxide and are produced through the burning of fossil fuels and various other means. These gasses are actually part of Earth’s natural processes, for they trap heat that allows Earth’s temperature to sustain life. The effects of this process can be seen as a blessing and a curse. Just the right amount of them helps the earth maintain a somewhat constant temperature; too much may cause temperatures to rise to frightening heights. Since 1880, when instruments used to precisely measure atmospheric temperatures were invented, the Earth’s surface temperature has risen about 0.36° F for each decade up to the twenty first century (Voiland). This information presents a clear warning about the matter: that global warming is present and cannot be ignored. Most extremists feel that global warming will lead to......

Effects of Global Warning

...The effect of global warming on the United States Global Warming was first recognized in the 1950's and will continue to be a problem for us, as humans keep contributing by releasing heat trapping gasses in our everyday life. The drought in Texas was very sever and caused a lot of problems while also creating expenses as well. Texas suffered from extreme wildfires in more than twenty cities. In the year 2011 there were 30,457 fires recorded in the state of Texas. More than seven thousand square miles of agriculture were burned. 3,017 homes were lost.7.62 billion dollars were documented in agricultural losses and 117 drought related deaths were noted (Amico). The greenhouse effect is a process by which certain gases in a planet's atmosphere give it a higher temperature than the planet would have otherwise. Light is one form of electromagnetic radiation. From lower energy to higher energy, categories of EM radiation includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Blackbody radiation is EM radiation given off by all matter, as a function of the matter's temperature. Hotter objects give off more total EM radiation, and also give off a greater fraction of that radiation as higher energy radiation.Since the Sun has a surface temperature of 5,700° C, about 42% of the blackbody radiation it radiates is visible light The Earth also radiates blackbody radiation but almost entirely as infrared light Certain gases in the Earth's atmosphere...

Global Warming

...Earth is home to an abundance of astonishing, complex forms of life. We humans are constantly learning more and more about this planet. Earth has been humanity’s mysterious home since the origin of our species, but in the last century or so there has been an alarming trend taking place. We have experienced the Earth’s temperature rising. Global warming is the name of the phenomenon that has taken place over approximately the past 133 years, and according to NASA, it is an un-debated fact that the average temperature on Earth has increased one and a half degrees over this time period (NASA). There is a wide range of thoughts and opinions on the relatively recent issue of global warming. To some people, global warming is out of our hands. Therefore, it is a non-issue. Others feel that the opportunity cost of trying to prevent it is too high, especially because global warming isn’t blatantly causing any suffering on a daily basis. The perspective I have towards global warming is one that is bearing a more inconvenient, burdensome argument. This is that human activity is causing the temperatures of the Earth to rise at an unnatural pace with the widespread emission of greenhouse gases. The purpose of this argument is to raise awareness through scientific and statistical studies that humans are to blame for this trend in climate change, and that there could be significant consequences to not taking preventative measures. To absolutely prove that humans are to blame, we would need......

Global Warning

...Global Warming Global warming is on an up rise! During this presentation one will understand the reasons behind that fact and by the end have a clear understanding that it is important that we start to make a change to our daily lives. This Project will go in full detail on the basics of global warming, the causes of global warming, and also the reasons behind the effect of climate change that is caused by global warming. First, it is said that humans are one of the reason for global warming due to the lack of being responsible. Scientists have determined that a quantity of human activities are donating to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide collect in the sky and trap heat that normally would exit into outer space. Secondly, it is becoming extremely obvious that some causes may come from bad habits in which is contributing to the carbon being released into the air causing our planet to become hotter. Lastly, climate change will occur and get worse over time and more natural disasters will take place. What are greenhouse gasses? Greenhouses gasses are emissions that are released into the air that in which causes natural disasters. There are several ways emissions are released into the air. First, if one drives a cars carbon monoxide leaks from it. To control car leak edge people started creating electric cars. In addition, using electricity from coal-fired power plants, or heating our......

The Illuminati vs. the Skeptics

...The Illuminati Versus the Skeptics Captivating and confusing, a conspiracy that dates back thousands of years and has no clear answer. The Illuminati, a mysterious secretive society with plans to conquer the world and rule with force, has fascinated conspiracy theorists since before modern times. Though the idea has been around for thousands of years, plaguing the minds of the easily convinced and threatening world domination, the question remains: is the Illuminati really a group of tight-lipped masterminds, secretive enough to hide their identities and existence? Or is this yet another easily arguable conspiracy theory created to shock the masses and instill hysteria in the general public? Before we can delve into that question, it is important to first attempt to understand the facts (or lack thereof) surrounding this “society”, by exploring the origin of the Illuminati, its members, and the “evidence” (or lack thereof) that proves its existence. As interesting or compelling as one set of facts may be, there are hundreds of other websites, documentaries, and books claiming to have found truth in another, entirely different, set of facts. For the sake of argument, several of the most prominent theories will be brought up and investigated. These sets of facts occasionally conflict with one another even on the most basic of topics. As is clearly visible when simply discussing the origin of the society, many different people hold onto very different ideas. ......

Trigger Warnings

...Coddling of the American Mind,” Greg Lukianoff and Jonathan Haidt state that the use of trigger warnings on college campuses are having unintended consequences. A trigger warning is used by a professor to notify students when they are about to discuss material that has the potential to be upsetting or offensive. Lukianoff and Haidt believe that these trigger warnings have been put in place to appease the student’s demands for a safe space where they can learn. The article opens by stating. “a movement is arising, undirected, and driven largely by students, to scrub campuses clean of words, ideas, and subjects that may cause discomfort or give offense.” The authors argue that this movement stems from a generation that feels entitled to the right to not be offended. This has led to a social environment where professors and students alike feel fearful to speak their mind freely. The trigger warnings these professors are using exasperate the current atmosphere of extreme political correctness. In the view of Lukianoff and Haidt, these trigger warnings are gasoline on the fire. Their claim is that the warnings lead to unforeseen consequences. The warnings lead to the censorship of controversial or challenging ideas. Due to this fact, this generation of students are graduating college ill prepared for the real world. To even further their claim, Lukianoff and Haidt state that trigger warnings lead to increased anxiety and mental illness. The author’s write about how......

Global Warning

...Global Warming There is no doubt that global warming is happing and that we have already seen some of the effects. Global warming is when increases in the earth's average atmospheric temperature corresponds with changes in climate and that may result from the greenhouse effect (Dictionary.com). Every year we see natural disasters that are extremely powerful. For example, In January of 2010, the country of Haiti was hard hit by an earthquake that took the lives of thousands of people. The very next month, Chile was hit with one of the most powerful earthquake ever been recorded. An Inconvenient Truth written by Al Gore, former Vice President of the United States, suggested that we should consider focusing on other dangerous things, meaning the cause of global warming. This implicates that despite the other problems each country is facing such as political, diseases, poverty and war; we should all unite to save our planet first. If we don't we are all in trouble at the same time. The scientist and the worldwide leaders have agreed that the climate change is caused by human activity, but yet we have done little to modify our environment. On the other hand the public has had enough about the climate change after having massive heat wave, snow, tropical storms, tsunamis and earthquakes. We all want to be part of this but it's often difficult to overcome modern life style therefore we need guiding. According to Al Gore' book, The United State is contributed more greenhouse gas......

Trigger Warnings

...Trigger Warnings is not bad idea to start adopting in our colleges and Universities. We are becoming so insensitive, with ourselves, as well respecting or understanding people’s feelings. We live in a society where, we want bluntness disregarding the consequences, or how it may affect people with traumatic events. The nuance of this controversial topic Trigger Warnings has arisen and we have to take in consideration that if students are asking for them, because there’s a whole reason for it. Trigger warning advocates a voice of students that can’t speak for themselves, about their fears, and what affects topics affects them in a classroom setting. Trigger warning and content notes are two different things that we need to understand. Trigger warnings is a clear and specific way of alerting students of certain information that would be discussed in class, example panic attacks due to strong material related to race, abortion or, war related material with high graphical content that could cause a student with PTSD could have flash backs. On like Content Notes, is different, it is a theoretical value to a neutral meaning that allows people to make a decision whether they want to engage in a material or not. But content notes doesn’t really serve the purpose as trigger warnings, although it could be associated, but in rare cases it talks about trauma content, or larger societal issues that provokes individual harm. We are not God or mind readers to judge people because of......

The Odds of Disaster: an Economist’s Warning on Global Warming

...No one can say with any assurance what the dollar value of damages would be from the highly uncertain climate changes that might accompany a planet earth that is steadily warming. Paul Solman: Are headlines trumpeting the fact that carbon dioxide levels in the earth’s atmosphere have now passed 400 parts per million for the first time in something like three million years unduly alarmist? Or are they a timely warning? I asked noted environmental economist Martin Weitzman to address the question. An expert on the Soviet economy in the ’70s and ’80s, Weitzman first made news in 1984 with the publication of a book called The Share Economy, an argument for profit sharing instead of fixed wages. Fourteen years later came his paper Recombinant Growth, which revolutionized how some of us understood the enormous potential of technology. But for many years, Weitzman has also been working on environmental economics and most recently, in a series of widely cited academic papers, on the economics of global warming; the most famous, on the “Economics of Catastrophic Climate Change.” Weitzman’s central idea is not unlike the legendary bet proposed by the 16th century Catholic French philosopher Blaise Pascal. One way to interpret Pascal’s argument: even if you think the likelihood of God’s existence is vanishingly small, the cost if you’re wrong — eternal damnation — is infinitely high. An infinite cost times even a tiny probability is still … an infinite cost. So you......

Global Warning Effect

...Global Warming and the Greenhouse Effect The Earth is kept warm by it's atmosphere, which acts rather like a woolly coat - without it, the average surface temperature would be about -18 degrees Centigrade. Heat from the sun passes through the atmosphere, warming it up, and most of it warms the surface of the planet. As the Earth warms up, it emits heat in the form of infra-red radiation - much like a hot pan emits heat even after it's taken away from the cooker. Some of this heat is trapped by the atmosphere, but the rest escapes into space. The so-called "greenhouse gases" make the atmosphere trap more of this radiation, so it gradually warms up more than it should, like a greenhouse (although a greenhouse actually does this by stopping warm air rising and escaping from it). What Causes The Greenhouse Effect? There are some natural greenhouse gases: water vapour, nitrous oxide, carbon dioxide, methane and ozone. However, over the past fifty years, production of carbon dioxide, nitrous oxide and methane has risen sharply, and a new type of chemical - the chlorofluorocarbon, or CFC - has been introduced as a refrigerant, solvent and aerosol propellant, but it is also a very powerful greenhouse gas, because it can trap a lot of radiation - one molecule of CFC is 12,000 to 16,000 times as effective at absorbing infra-red radiation as a molecule of carbon dixide. This graph shows how much each gas contributes to the greenhouse effect, taking into account how much......
