How does Human Activities have an Effect on Climate Change?

â€Å"Humans are almost entirely the cause† of climate change, according to a scientist who once doubted that global warming even existed. As many scientists and physicists across the world believe that human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. A recent report of the Intergovernmental Panel on Climate Change states that the largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared (thermal) radiation that are part of Earth’s energy balance. Furthermore, changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. Since the start of the industrial era (about 1750), the overall effect of human activities on climate has been a warming influence. The human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruption. As a result it is clear why climate change has such a big impact on our planet and what it has in store for our future as well. It is caused by many reasons as stated above, with supporting evidence it no doubt that climate change is becoming serious as time passes. Most climate scientists agree the main cause of the current global warming trend is human expansion of the greenhouse effect. Certain gases in the atmosphere block heat from escaping. Long-lived gases, remaining semi-permanently in the atmosphere, which do not respond physically or chemically to changes in temperature, are described as â€Å"forcing† climate change whereas gases, such as water, which respond physically or chemically to changes in temperature are seen as â€Å"feedbacks. Many of these gases are water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons. The role of humans play a very important role in climate change, in its recently released a recent report called, the Intergovernmental Panel on Climate Change, which states, 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 90 percent probability that human activities over the past 250 year s have warmed our planet. Furthermore, it concludes that the industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to 379 parts per million in the last 150 years. The panel also concluded there's a better than 90 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in Earth's temperatures over the past 50 years. They said the rate of increase in global warming due to these gases is very likely to be unprecedented within the past 10,000 years or more. Scientists have blamed human activities such as causing a negative effect on the planets natural resources such as increasing amount of greenhouse gases releasing into the atmosphere, burning more unnatural sources, and cutting down more forests. As a result, restricting the use of unnecessary resources and contributing to a cleaner process. Many reports state that when humans burn gasoline, coal, natural gas, and other common fuels to make electricity or drive cars, they release a substantial amount of carbon dioxide into the atmosphere. For every gallon (or liter) of gasoline your car burns, 1300 times that volume of CO2 is released (a gallon of gas weighs about 6 pounds or 2. 8 kilograms, but the released CO2 would weigh over 19 pounds or 8. 75 kilograms). Greenhouse gases are emitted from power plants and cars, but also from landfills, from farms and cleared forests, and through other subtle processes. Many contributions and research have proven many of this facts one of them is the use of modeling with the aid of computers. To prove the case that climate change is mostly caused by humans, scientists had to take into account other factors: complicated atmospheric physics, the interactions between air and land and between air and water, changing amounts of ice and of desert and forest, and the natural processes that have changed the climate for 4. 54 billion years. To do all this, scientists recreate the crime scene. Because there’s only one Earth, they do that with computers. Climate scientists use powerful computers to construct models based on physics of the climate system. These models enable scientists to make predictions and test hypotheses about what processes affect the climate. These models are based on the fundamental of science, many of them include thermodynamic principles, orbital dynamics, and the balance of heat entering and leaving the atmosphere. Scientists can do experiments with these models that they can’t do on the planet. They can set the atmosphere to match conditions a century ago, and see whether the model’s predictions match what scientists measured at the time. And they can set the models to match conditions millions of years ago, to better understand how past climate changed. This allows them to verify that the models are accurate and to fine-tune the output. They can also remove the effects of human activities from the models, and see how much of the climate change they observe is still predicted by the models. As a result, there is very little time on what necessary steps must be taken in order to decrease the climate change and stabilize the amount of greenhouse gases omitted into the atmosphere. Certain gases in the atmosphere block heat from escaping therefore are resulting in an increase on the rate of global warming throughout the planet Climate scientists use powerful computers to construct models based on physics of the climate system. These models enable scientists to make predictions and test hypotheses about what processes affect the climate. Many hard proved evidence point to only one reason, which is towards human activities, resulting in a negative effect throughout the Earth’s atmosphere causing many disasters, climate change, raise in sea levels, and most importantly a threat to the human race, and other life forms.

Equal Protection in Criminal Punishment

Equal Protection in Criminal Punishment The 14th Amendment articulates that no State shall â€Å"deny to any person within its jurisdiction the equal protection of the laws† (Sullivan and Gunther 486). It is nearly impossible though, for the equal treatment of all persons, since every law affects people differently. â€Å"This command cannot literally require equal treatment of all persons, since almost all laws classify in some way, by imposing burdens on or granting benefits to some people and not others† (Sullivan and Gunther 486).The Equal Protection Clause was meant for the application of all laws equally, not necessarily equal treatment of all people. There is a great difference in the two. The people most adversely affected by these iniquitous laws are mainly minorities and those from low socio-economic groups. The inequality in sentencings of the criminals is often the focal point of legal discussion. The most debatable topic when it comes to criminal punishment is the area surrounding the death penalty. It is often given unjustly and undeservingly to minorities.Race is the most controversial and monumental factor in determining the length and severity of a criminal’s punishment. Racial discrimination has been evident in our legal system in the past and continues to remain present to this day. Our court system has deprived minorities of their rights throughout the years. In Strauder v. West Virginia, the State excluded blacks from the jury. The State law stated that â€Å"all white male persons who are twenty-one years of age and who are citizens of this State shall be liable to serve as jurors† (Sullivan and Gunther 487).A black man facing trial in the 1800’s against an all white jury doesn’t stand a chance. The Court found that to deny citizen participation in the administration of justice solely on racial grounds â€Å"is practically a brand upon them, affixed by law; an assertion of their inferiority, and a stimulant to that race prejudice which is an impediment to securing to individuals of the race that equal justice which the law aims to secure to all others† (Sullivan and Gunther 487). This case was a major turning point in racial discrimination in our legal system.Minorities were starting to be seen as people, and not just objects. But at this time, we were still far from our goal of total equality among all people. In a more recent case, Swain v. Alabama, the Court held that a defendant in a criminal case is not constitutionally allowed to a balanced number of his race on the trial jury or the jury panel. There is no evidence in this case that the jury selection committee applied different jury selection standards as between blacks and whites (Swain v. Alabama, 380 U. S. 209, 1965). There may not be evidence, but it is quite obvious that there is an inequality here.How can a man facing a death penalty be put up against an all white jury during a time of racial tension? A f lawed system of selection of jury panels is not comparable to intended racial discrimination (Swain v. Alabama, 380 U. S. 209, 1965). Although the selection of an all white jury was not sought out, society during this time was racially divided. The principle announced in Strauder v. West Virginia, that a State denies a black defendant equal protection when it puts him on trial before a jury from which members of his race have been purposefully excluded, was reaffirmed in Batson v.Kentucky (Batson v. Kentucky, 476 U. S. 84). The Equal Protection Clause assures the defendant that the State will not prohibit members of his race from the jury venire on account of race, or on the inaccurate assumption that members of his race as a group are not eligible to serve as jurors. By denying a person participation in jury duty on the basis of his race, the State also unconstitutionally discriminates against the barred juror (Batson v. Kentucky, 476 U. S. 85). This inequality in the selection of jurors has damaged confidence in our legal system.The lack of confidence has in turn caused inequality in the sentencing of criminals, mostly dealing with minorities. There is no doubt that minorities receive harsher and longer sentences. â€Å"As of June 1998, only seven white men had been executed in the United States for killing black victims. In the same 1976-1998 period, 115 black men were executed for killing white victims† (Cole 132). These numbers prove that blacks have historically received harsher treatments than whites. This connects to the selection of juries. Juries have a great affect on the sentencing of criminals.A predominantly white jury is more than likely to convict a black man, than a predominantly black jury is. â€Å"Juries remain predominantly white in most of the country, and apparently their sympathies lie more strongly with white than black victims† (Cole 133). A large study conducted by Professors David Baldus, George Woodworth, and Charles Pulaski, showed that there was a large disparity in the racial breakdown of the death penalty. They found that defendants charged with killing white victims received the death penalty eleven times more often than defendants charged with killing black victims (Cole 133).The Equal Protection Clause was set out to protect from this indifference, but this clearly shows that it has not done so. Equal treatment of all people has yet to be achieved today and racial inequality is still ever-present. Criminal sentencing when it comes to blacks and whites is vastly different and unjust. The disproportion of sentences given to blacks and whites in dealing with drugs is ridiculous. First of all, the gap in sentencing when it comes to crack cocaine and powder cocaine is too big.Under federal sentencing guidelines, a small-time crack dealer caught selling 5 grams of crack receives the same prison sentence as a large-scale powder cocaine dealer convicted of distributing 500 grams of powder cocaine (Cole 142). To me, powder cocaine is just as dangerous and addicting as crack cocaine. The large gap in sentencings for the two offenses places a higher value on the danger level of crack, when in all actuality they are on the same level. The increase in policing of the low-level crack offenders has caused us to neglect the big drug traffickers.As it is, we already do not have enough federal law enforcement to police all the drug dealers out there. By paying more attention to the people with small amounts of crack cocaine, we are letting others get by with more powdered cocaine. This puts more powdered cocaine on the streets, because dealers are unafraid to receive the consequences since the pay-off to conviction rate is much more in their favor. An offender would receive a mandatory minimum of 10 years if they were to get caught with 5,000 grams of powdered cocaine, while a person would receive the same sentence for being caught with only 50 grams of crack cocaine.Crack cocaine is the only drug that carries a mandatory prison sentence for a first-time possession offense. A person convicted in federal court of simple possession of 5 grams of crack is subject to a mandatory five-year prison term while a person convicted of possessing 5 grams of powder will probably receive a probation sentence. To solve this problem, we need to bridge the gap between the two sentencings. Crack cocaine is the poor man’s powdered cocaine. The popularity of crack cocaine was associated with its cheap price, which for the first time made cocaine available to a wider economic class (thesentencingproject. rg). More than often, the biggest users of crack cocaine are people of lower social status. This in turn implicates that more crack cocaine users are African Americans. As a result of this, blacks are receiving more prison time when it comes to crack cocaine. African Americans make up one-third of crack cocaine users, with the other two-thirds being white and Hispanic (The D efenders Online). About 90 percent of federal crack cocaine defendants are black (Cole 142). African American drug defendants have a 20 percent greater chance of being sentenced to prison than white drug defendants (The Sentencing Project).Why is this the case? The legal system inadvertently targets blacks by placing higher sentences on crack cocaine offenses. A considerable racial disparity in prosecutions and imprisonment has endured for too long. Along with disproportionate law enforcement procedures that aim towards blacks, the crack sentencing guidelines have resulted in more than 80 percent of crack cocaine defendants being African American, although in all actuality, a majority of crack offenders are white or Hispanic (The Sentencing Project).With the punishment of crack cocaine so severe for low level offenses, the prison incarceration rate has risen, causing us as taxpayers more money. American prisons and jails house nearly two million people and Blacks face incarceration rates more than six times that of Whites (Schlesinger). The inequality in our justice system has caused more minorities to be locked up, which in result is a financial burden on the American taxpayers. By equalizing the gap in criminal sentencing for all races, we can solve the problems from within our legal system.The racial inequality that is present in our justice system also exists in the sentencing of the death penalty. There seems to be a consistent factor in those on death row. â€Å"Those being executed and awaiting their deaths are no different from those selected for execution in the past: virtually all were poor; about half are members of racial minorities; and the overwhelming majority where sentenced to death for crimes against white victims† (Bright 433). Over time, our legal system has placed a â€Å"small† value of importance on minorities and this was built upon, to where whites did not notice this inequality.There has to be some sort of factor that in fluences why there are more minorities on death row. A possible influence on the situation could be the fact that most prosecutors are white. â€Å"98 percent of all state death penalty state prosecutors are white and in eighteen of the thirty-eight death penalty states, prosecutors are exclusively white† (Free 187). White prosecutors may not knowingly have a racial bias in their head, but it is evident when they are trying to seek the death penalty. State courts were 4. 3 times more likely to sentence those who killed whites than those that killed blacks (Free 185).These same courts were 1. 1 times more likely to black defendants to death than any other defendant of another race (Free 185). While the state prosecutors are pressing for the death penalty, the defendant is supplied with an insufficient lawyer. The jury is more than likely to listen to the more qualified state prosecutor and be persuaded by what he has to say, over the under qualified attorney supplied by the st ate. This has resulted in more successful cases in favor of the state prosecutors. This reoccurring situation is ever-so-present in today’s legal system.Minorities are getting shafted in the American justice system and nothing is being done to prevent this from continuing to happen in the future. ‘All men are created equal†¦ ‘ may be what the Declaration of Independence says, but in all reality, some men receive better treatment than others. The actual reality of the Declaration of Independence is that all free, white, landowning men are created equal. For that reason, inequality has always been present in the United States' legal system and maintains to exist today; though, the inequality currently in the system is not as obvious as what it once was.We have made little progress towards total equality. Anywhere you look in today’s world, you can find some sort of inequality or injustice. I firmly believe we will always have a racial prejudice in the wo rld no matter what, because there will always be the people that can’t get over their racial indifferences. Although we will not fully achieve the goal of racially equality, we can make positive steps forward by first addressing the problems associated with in our justice system. Race is the largest influencing factor in the sentencing of criminals, especially when it comes o dealing with the death penalty.

International law. The case Essay Example | Topics and Well Written Essays - 750 words

International law. The case - Essay Example Natural products are fetching ever more precious in today's society. An important part of the shopper market is persuaded that natural products are linked with security and health, while artificial products are linked to unwanted side effects. In reaction to this trend, significant shifts are happening in many industrial sectors, such as food, drink, cosmetics and pharmaceuticals, mostly because of rising feelings of the benefits of "lifestyle in agreement with nature". Since gathering consumer wants and expectations are of main significance for companies' competitiveness, there is a "gold race" for the use of natural elements as raw materials to expand a broad diversity of products. According to the Expert Ferreira, the "green wave" has led therapeutic plant sharing companies to seek "new products", with a sight to supplying the increasing demand in this market. Certainly, the similar thinking could be extensive to other industrial sectors intimately connected to human health, hygiene and food. This is the cause why rising countries abruptly discover themselves in the attention because of the sometimes huge biodiversity of plants rising within their boundaries. According to the Constitution of the United States gives Congress the authority to pass laws connecting to patents, in Article I, section 8, which reads "Congress shall have power to endorse the development of science and helpful arts, by securing for imperfect times to authors and inventors the elite right to their individual writings and discoveries." (US Constitution online, 2006) Under this authority Congress has from time to time enacted a range of laws relating to patents. The first patent law was enacted in 1790. The patent laws underwent a universal revision which was enacted July 19, 1952, and which came into result January 1, 1953. It is codified in Title 35, United States Code. As well, on November 29, 1999, Congress enacted the American Inventors Protection Act of 1999 (AIPA), which more revised the patent laws. See Public Law 106-113, 113 Stat. 1501 (1999). The patent law specifies the topic substance for which a patent may be obtained and the conditions for patentabili ty. The law establishes the United States Patent and Trademark Office to administer the law connecting to the yielding of patents and contains a range of other provisions linking to patents (Ray, 2003). A product can not be patented if any information is already available about it in any domestic or international level journals. So giving patent rights to Omni was wrong and the request for revocation should be granted as information was available in journal articles present in the libraries of state Y. Patents on Natural Products Investments in study and development are closely related to the hope of obtaining rights over the results, in order to recompense for the money spent throughout the work, which can be important through many years of study. Thus, given the spirited nature of modern life, it has become essential to offer incentives for study and growth

My Leaders Profile in early childhood Assignment

My Leaders Profile in early childhood - Assignment Example In this paper therefore, the profile of the Director and nominated Supervisor of Maryland Early Childhood Center based in Sydney, Patricia1 is presented. According to (Leithwood, Day, Sammons, Harris, and Hopkins, 2006), the directors of early childhood educational institutions have to be proficient in teaching strategies, group dynamics, conceptual skills in child development, adept in understanding and implementing issues to do with the correct moral purposes to adopt, and be goal oriented. The profile is therefore presented in a manner that seeks to examine the key characteristics, knowledge, skills, and personality of Patricia to critic how well they match with the proficiency guidelines for directors outlined by Leithwood, Day, Sammons, Harris, and Hopkins (2006). Section 3: My Leader’s Story Introduction Thornton (2005) has argued that early educational school directors should be able to budget their time in such a way that they make time for the parents of their charges so as to discuss the progress of the children. What this implies is that the leader of an early childhood institution must have a social structure principle that focuses not only on the children who are put in their care but also on other agencies such as the home and how such agencies can make their functional duties easier. Indeed, this is a characteristic that my leader has exhibited in her numerous years of experience as a director as she has a story built on the success she has seen as a result of collaborative leadership style with parents and other stakeholders. For instance as noted by Rodd (2005), he has already begun to foster strong networks with other Early Childhood agencies that are located within the community. Management Role The job title of the leader is Nominated Supervisor of a Centre-based child care service. She currently holds the position as a director. Some of the major job descriptions of the director, as specified under the Education and Care Service Nati onal Law and Education and Care Service National Regulations are given as listed below: She is expected to ensure the effective day to day administrative operation of the service and also to make sure that the Centre meets the Education and Care Services National Regulations at all times. What is more, she is required to comply with the National quality Framework and standards to maintain high quality care and education. To achieve this, it is expected that she will ensure compliance with the code of conduct at all times and be responsible for the care and education of each individual child attending the service. Her job description gives mandate over her staff as she is to ensure that adequate supervision and direction is provided for children by ensuring the prescribed educator to child ratios are met and each educator at the service meets the qualification requirements relevant to the educator’s role2. Several more of these job descriptions have been attached at the append ix 2. Generally, management roles can be defined from three major perspectives namely planning, organisation and monitoring, out of which McCrea, N. & Ehrich, L. (1999) have devised the POM model. Model of Management Process McCrea, N. & Ehrich, L. (1999) From the diagram presented above, it would be realised that all three

Response - Article Example These include the European Language Portfolio or ELP, American Lingua Folio, and Global Language Portfolio (GLP). The researchers on the portfolio assessment have been building on the work of Dewey (1933), which is titled, â€Å"We Thing: A restatement of relation of reflective thinking to education process.† He built basic premises, which are still evident in both ELP and GLP, and involves reflecting on and summarizing what has already done. The article provides an overview on how the EPs can be used to learn, teach and assess in the United States and Europe based on ELP, CEFR, GLP and American I.F. The EPs function is based on the national standards and ACTFL proficiency scale. There are several advantages that EPs has over paper based portfolio. The functionality of EPs allows the learner, teacher and program coordinator to track the progress of the program throughout the course duration. It allows the learner to share data with both the teacher and the institution. It improves motivation and evaluation of learners’ outcomes. Through the cooperation of scholars from Europe, North America and other parts the world, the effectiveness of EPs for language acquisition will be realized. As the transatlantic partnership grows and higher learning institutions do joint programs, the three-part EPs will be a common technology in Europe and North America. Advancement in technology will facilitate information sharing among international institutions and their joint programs. The Electronic Portfolio (EP) is a digitized collection of artifacts, which include demonstrations, resources and accomplishments representing an individual, group, organization, institution or community. According to Lorenzo & Ittelson (2005, p. 2), these collections can comprise of text-based documents, graphics, and multimedia features archived on websites or other electronic media such as CD-ROM or DVD. The above features make Electronic Portfolio to be the best in

Genesis and exodus Essay Example | Topics and Well Written Essays - 250 words

Genesis and exodus - Essay Example God also assures Abraham that after punishment He will raise up the Israelites and lead them to the Promised Land. After 400 years of hardship and torture in the exile, the Israelites were ready to leave Babylon and go back to rebuild Jerusalem. However, bearing in mind that it was not an easy task, the books of Isaiah and Genesis encourage the exiles to leave Babylon and go back to rebuild Jerusalem. In order to encourage exiles, these two books (Isaiah and Genesis) used different means including reminding them of the God’s promises. For instance, the book of Genesis reminds exiles how God entered into a covenant with Abram. The book of genesis states that â€Å"And Abram fell sound asleep when the sun went down. Then he was overwhelmed by a great terror. Then the Lord said to him, â€Å"Know for sure that your descendants will be strangers in a foreign country. They will be oppressed and enslaved for 400 year. But I will execute judgment on the nation that they will serve. Afterwards, they will come out with numerous possessions. But for you, you will join your ancestors peacefully and be buried at a good old age. In the fourth generation your descendants will come back here, for the sins of the Amorites have not yet reached its limit.† When the sun had gone down and it was dark, a smoking firepot with a flaming torch passed between the animal parts† (Gen. 15: 12-17) On the other hand, book of Isaiah encourages exiles by also reminding them God’s plan. For instance the book of Isaiah states that â€Å"Now, this is what the Lord says, the one who created you, O Jacob, and formed you, O Israel: â€Å"don’t be afraid, for I will protect you. I call you by name, you are mine. When you pass through the waters, I am with you; when you pass through the streams, they will not overwhelm you. When you walk through the fire, you will not be burned; the flames will not harm you. For I am the Lord your God, the sovereign king of Israel, your deliver. I have handed over

Consumer Cultures, Environmental Futures Essay Example | Topics and Well Written Essays - 1750 words - 1

Consumer Cultures, Environmental Futures - Essay Example Catfish is one of the types of fish that people consume, which differentiate the consumers along different lines of the economy, society and political differences. Through this differentiation, people have different perspectives of looking at the catfish both from the perspective they may have from the influence they have from their culture and social ties. The analysis of production and consumption of catfish will help in explaining the various reasons that make it a consumer product of a specific group of people within a society, which may mean a lot of structure formulation within a society. The analysis focuses on the sources of catfish and the places in which it is a common form of food while in some others; it could be a rare commodity (Tucker and Hargreaves, 2004, p.27). Catfish are popularly produced in different places in the world as one of the small-fish that people consume as food for their own and which they sell to a few people around their environment. However, researc h shows that production of small-fish in sector of fishing is an aquaculture that usually target different people who fall in the low economic classes in the society. In the economy, consumption of these small-fish is therefore, related to specific people in the country who could be a having similar general characteristic (Tucker and Hargreaves, 2004, p.39). Catfish is mostly common among the Vietnamese who invest in production of the organisms for food in different place in both large-scale and small-scale levels of the economy. This production is facilitated by the demand that is raised for the food that that has some contents of fish and the different levels of production of catfish through the aquaculture technology implies the different demanding issues that surround food fish production within the society. In this respect, when food fish demand increases, people have adopted various ways through which they can improve the amount of products they obtain from their investment. I n the Vietnamese culture, fish are highly regarded and therefore, people adopt aquaculture in order to meet the local demands as well as the needs of others that are away from the country. In the aquaculture for production of the catfish species of the fish, there are different factors that favour the production in the area, which motivate people to invest in the production as a mode of subsistence or as a commercial activity. In order to produce, people depend on different opportunities that the environment offers, which help people to exploit it for their benefit. In this respect, people have different ways through which they produce the catfish to the different market in Vietnam or away from the country. The most common factors that are important in determining the production of the catfish include the sources of water where the fish will grow, the availability of fingerlings that grow to be the mature catfish and the space that is available for people in to establish their produ ction and the aquaculture. In most cases, people who invest in aquaculture try to establish their production by varying the conditions in the condition of the environment to allow the production even in places that are not very favourable for production. This aquaculture in
