...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 pollution...

...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...

...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...

...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. The...

...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 make...

...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 of...

...BP bears brunt of blame for the deepwater horizon catastrophe for Report says oil company is 'ultimately responsible' for oil spill but rig contractors also implicated in some areas BP’s share prices rose almost 5% but fell back after report was published Photograph: Molly Riley/REUTERS A key US federal report has focused the blame for the worst offshore oil spill in US history on BP, but criticised its contractors sufficiently for the markets to push BP's share price up. Amid a string of failures, BP's "cost or time-saving decisions… were contributing causes of the blowout," the report concluded. Assigning ultimate responsibility for the disaster – and the billions of dollars of clean-up and compensation costs – will take years of legal action, but Wednesday's investigation report was seen as a significant indicator as it was conducted by the regulator responsible for offshore activities. The blowout at the Deepwater Horizon rig in the Gulf of Mexico in April 2010 killed 11 people and led to almost 5 million barrels of oil being spilt into the ocean. BP's share price rose almost 5% in London on rumours the report would help avert the company being found grossly negligent in future, which would increase its financial liabilities hugely. But it fell back after the report was published, finishing the day up 3.5% at 395.1p. The investigation, jointly conducted by the Bureau of Ocean Energy Management, Regulation and Enforcement (Boemre) and the US Coast Guard, stated that a...

...LRR#1 Bryan Smith Lab Research Report # 1 Strayer University SCI 110.109GA063-1142-001 Introduction to Physical Science Professor Larry Smith January 27, 2014 The world has always been amazed with astronomy which is the study of earth, planets, space, and the universe as a whole. This is one of the oldest practice since the beginning of time. Many civilizations have studied this for years. This was before anyone came up with the idea to build a ship to visit other planets. People have always been amazed by the unknown, and this is why we still have people going to outer space to discover new things. The use of the research for studying outer space is known as Astronomy. According to the web dictionary Astronomy is the scientific study of the matter in outer space, especially the positions, dimensions, distribution, energy, and evolution of celestial bodies and phenomena (http://www.thefreedictionary.com). Early scientist could not just look up in the sky to measure how far away a star actually is and to see what else is up in space. There is other techniques and equipment is needed. Early scientist use a technique called triangulation. This was done by looking at a star and record its location. Then six months later scientist would look at the star again and measure the distance and record any changes (How are astronomers, 2000). The strength of an earthquake by measure the level of shaking on the...

...The Miranda Rights are the most common legal issues that must be observed when conducting an interview or an interrogation. Suspects are presumed innocent until proven guilty, and they have rights that must be respected. Arresting officers must always inform suspects of their alienable rights. Failure to inform the suspect of his or her rights can lead to legal technicalities that can render any information taken during the suspect’s interview or interrogation null and void. The Miranda Rights provides protection based on a person’s Fifth Amendment rights to prevent self-incrimination. There rights are recited to individuals while being taken under custody. These rights are read, “You have the right to remain silent. If you give up the right to remain silent, anything you say can and will be used against you in a court of law. You have the right to an attorney. If you desire an attorney and cannot afford one, an attorney will be obtained for you before police questioning” (Criminal Law, n.d.). A pertinent legal issue associated with security interrogations is the authority to make judgment calls. There had been many debates on interrogation tactics used to elicit a confession from a suspect. The use of torture is a common issue of contention in modern society. The dilemma of whether it is acceptable to use torture to save lives had been debated in courtrooms, senates and public forums with no definite policy set in place. In the interrogations of top Al-Qaida operatives in...

...of my time speaking to the media about incidents of child abuse 'after the fact" when people are trying to make sense of why and how it could happen. But instead of focusing on what we can do with the creeps after they're caught, I would rather give parents some information to empower them to keep their kids safe. After all, you will never be able to control others' behavior, but you can control your own. The first thing to remember is that pedophiles are master communicators. They are very good at sliding into a family and befriending the parents to gain access to their kids. But there are warning signs that you can look for that may indicate someone has less than honest intentions with your family. Preferential child molesters and pedophiles have distinct patterns of behavior that are highly predictable. As a parent, it is crucial that you learn to identify these patterns as warning signs, as they are an extremely valuable tool in assessing whether someone represents a risk to your children. Each one of these characteristics, taken on their own, can mean little. But if you can identify a large number of them in an individual you know, you need to remove that person from your child’s environment and never allow him to have unsupervised access. A pedophile could be someone who: 1. Shows an intense interest in children and childlike things. It is hard not to care about kids. In fact, you may be suspicious of those who show no interest in children at all. However, there...

...an earthquake is approaching, and this will give you some time to go to a safe place near your location. The “ShakeAlert System” works thanks to its vast ability to transmit information at the speed of light. The sensors located nearly to the epicentre capture the waves with seconds in advance; this will send the alert to the near locations. For now the system emits a very thunderous sound, a count down of the situation that is approaching, the expected insensitive, the estimated magnitude and a map of the location. This idea started developing few years ago, with the idea to be implemented in all the California state, but there is a lack of finance in the project. Governor Jerry Berry Brown approved a bill to create an early warning system. However, “ShakeAlert System” doesn’t have enough support with their work. It will cost $80 million over five years to test and deploy the...

...Introduction In the current days, the characteristics and needs of the patients in Australia and the rest of the world keep changing. The hospitals have been receiving an increased number of patients with different ailments and sometimes they get more ill during their stay in the health facility. The warning sighs always show on a patient before the adverse events such as unexpected deaths, admission to the ICUs or even cardiac arrests. It has been noted that, these warning signs are sometimes not identified, hence not acted upon (Adam, Odell, & Welch, 2010). This study is meant to discuss the case of Mrs. Jones, a 72 year old lady who has been admitted in the ward with increasing confusion and decreasing mobility. Her recent history suggests that she has had Urinary Tract Infection, and she usually has a GCS of 15. Her normal blood pressure always ranges from 140 to 150. During the primary assessment, it is noted that she is not in danger and she opens her eyes when her name is called. She is able to talk and her airway is patent. Her accessory muscle use is increases; her RR is at 22 and SP02 is at 95% on room air. She is also pale and diaphoretic. Her pulses are weak and thread y with the heart rate of 120 and blood pressure of 95/50, GCS at 13/15, temp at 38.5, BGL at 13.2mmol/L and pain in the lower abdomen.

...workday, should set off an alarm. This is a significant sign for an individual who is typically prompt and committed to a full workday. 2. Increased need for supervision: Generally, an employee requires less supervision as he or she becomes more proficient at their work. An employee who exhibits an increased need for supervision, or with whom the supervisor must spend an inordinate amount of time, may be an individual who is signaling a need for help. Managers should be alert to such a change and consider offering professional intervention if needed. 3. Lack of performance: If an employee who is normally efficient and productive experiences a sudden or sustained drop in performance, there is reason for concern. This is actually a classic warning sign of dissatisfaction, and the manager should meet with the employee immediately to determine a mutually beneficial course of action. 4. Change in work habits: As in the case of reduced productivity, an employee exhibiting inconsistent work habits may be in need of intervention. If you think about your peers at work, they are typically quite consistent in their work habits. If habits change, the manager has reason to suspect the individual is in need of assistance and action should be taken. 5. Inability to concentrate: If an employee is suddenly unable to concentrate, this may indicate that they are distracted and in trouble. A manager should be notified to try and encourage the employee to seek assistance. 6. Signs of stress: If an...

...Case Study: The Simon Gittany Murder Case Word count: 1543 Type of Homicide Simon Gittany was charged with the murder of Lisa Cecilia Harnum on 30 July 2011, was later found guilty on 27 November 2013 and sentenced to 18 years imprisoned without parole. At the time of Lisa Harnum's death, she and Simon Gittany were living together and were engaged to be married. Their apartment was on the 15th floor of a block of apartments in Sydney. Miss Harnum fell to her death from the balcony of that apartment. Simon Gittany was found to have deliberately lifted Miss Harnum over the balustrade and "unloaded" her body over the edge where she then fell to her death. The type of homicide featured in this case was murder. The intention to kill was formed quickly in a state of rage. It was not proven to be premeditated, there was a witness who came forward late in the trail stating that Lisa Harnum had spoken with her about receiving threats of murder from Simon Gittany this evidence was not included in the trail. The judge said with regards to Simon Gittany’s intention to kill Lisa Harnum “On the basis of my inspection of the balcony during the course of the trial, and in particular its height from the ground below, I am satisfied beyond reasonable doubt that the act of unloading the body from that height can only have been done with the intention of killing Ms Harnum”.
