A Fossil Free California Really - 1600 Words

A Fossil Free California†¦ Maybe Dr. Dan Jacobson a Professor at Stanford University has presented what he calls a â€Å"roadmap† to getting California to be run completely on renewable sources of energy by 2050. No â€Å"clean coal†, no natural gas, no nuclear, no biofuels, and no new hydroelectric. The golden state would be powered by wind, water, solar, geothermal, among a few others. And although i would love nothing more than to see california running completely on renewables by 2050. I think a transition completely off of fossil fuels cannot happen soon enough. Fossil fuels are toxic, hazardous to transport, disastrous to dig out of the ground and contribute to an accelerated warming of the planet. Jacobson notes that his map will create over 200,000 net 40 year jobs, reduce mortalities associated with air quality, and significantly cut worldwide carbon dioxide emissions. I do not disagree with any of these facts, becoming completely fossil fuel independent will lead to better health for ourselves, the earth, and the economy. think Dr. Jacobson makes some vital errors in neglecting to mention the much needed energy paradigm shift and in not addressing the issues associated with production of the renewable energy components. California is projected to use 280 GigaWatts of power by 2050 and see a population increase of thirty-five percent. 280 GW’s is a lot of power, currently all of the wind turbines in the world combined are capable of producing just under 300 GW’sShow MoreRelatedNuclear Energy For A Green Earth1164 Words   |  5 PagesNuclear Energy for a Green Earth Today the U.S. is still enormously dependent on fossil fuels despite the numerous advancements in alternative power sources (Solar panels, wind turbines, etc.).

Essay on Popular Mechanics Analysis The Need for Good...

In many ways, communication is important in resolving problems, strengthening relationships, helping others, becoming proactive, and much much more. Raymond Carvers novel Popular Mechanics illustrates the intense need for good communication. The story starts out with the couple fighting and the wife kicking her husband out of the house. She is being rude and aggressive and is not using proper communication, trying to cover the fact that deep inside she truly doesnt want him to leave. Then, the husband gets upset for the way he is getting treated by the wife and starts to get aggressive yelling that he was going to take their new born baby with him. She, being frightened and scared of his impulsion, runs into the kitchen trying to find†¦show more content†¦I stand by my opinion for this simple reason. the way that the couple talk to each other, they are almost competing over who is more in control. I want the baby He said. Are you crazy?. This shows that on the surface, the husband is getting upset and needs to show his manliness by taking control of the situation and of the relationship. Thus concluding the poor relationship When the father is being treated disrespectfully by his wife, he feels emasculated and/or feeling treted unfairly from the wife not treating him with respect and giving the father the picture of the baby, so becoming angry he decided he wanted the baby instead of the picture. Though people may dis-agree with my reasoning, everyone can agree that with poor communication, bad or un-needed situation will become much more frequent. This is why I stand strong next to my position stating that thhe theme of the short story Popular Mechanics By Raymond Carver is that in certain situations, proper communication and resolution tactics are extremely important; and without them, unfortunate things will happen.

Sustainability and environmental accounting Example

Essays on Sustainability and environmental accounting Essay Outline potential sources of information that superannuation funds could use to gather data about a company’s sustainability operations. Potential sources of information about sustainability of companies’ operations Information used by superannuation or pension funds may be classified as published reports by companies, completed studies or advisories contracted from third-party information providers, or primary and secondary data gathered by the fund’s staff for in-house analysis where the information is assessed. 1. Company issuances Corporate social responsibility (CSR), good governance, and environment sustainability compliance reports published and released by the companies themselves. These are in the form of firm-issued, general purpose non-financial reports prepared for the benefit of shareholders, stakeholders, and the public in general, either as standalone or integrated reports to comply with mandatory regulations (Godfrey, et al. 2010). The quality of corporate reporting may be hampered by practices considered deficient to satisfy the information needs of different readers, including superannuation funds (Rankin, et al., 2012). 2. Studies and advisories provided by external information providers Superannuation/pension funds rely on external sources of information because: Judging sustainability issues deserve attention in each sector requires specialised knowledge and broader information which the fund’s staff members do not have and could not acquire (or could acquire only at great expense); and For most funds, sustainability is only a secondary criterion or supplementary topic, the main criterion being the ability of the firm to generate consistent returns (Kasemir SÃ ¼ess, 2002, p. 21). 2.1. External providers of sustainability investment services Superannuation or pension funds which include sustainability criteria in its choice of portfolio tend to rely on external providers of sustainability investment services. Such services are known as ‘sustainability contractors’ and offer portfolios or corporations rated to have a ‘good sustainability record’ (Kasemir SÃ ¼ess, 2002, p. 20). In this case, the investment process is delegated to the investment service provider, also relying on their expertise. 2.2. External agencies assessing environmental and social reports by corporations 2.2.1. Agencies provide support to funds through reports analysing all major corporations categorized by factors (Kasemir SÃ ¼ess, 2002, p. 20). The fund retains the prerogative of deciding which corporations to invest in depending on the factors it has chosen. 2.2.2. Commercial research companies provide information to funds concerning the sustainability performance of companies grouped according to industries and rate them according to a set of criteria, ranking or rating the companies against each other (Super Ratings, 2012). 2.3. Non-commercial providers of sustainability information 2.3.1. Such sources as non-governmental organisations (NGOs) provide information for decision-makers of funds on a for free. Such information may be somewhat general in character with qualitative analysis and quantitative data per company (Jackson, 2006). 2.3.2. Academic sustainability assessments are seldom used, and when they are they are used only as supplementary information, because they are usually indepth and require a great amount of time to read (Kasemir SÃ ¼ess, 2002, p. 21). 3. Information sources for internal/ in-house assessment Some funds prefer to conduct their activities in-house with primary research, because: Mixing analysis from several outside sources may have applied different paradigms or models and would therefore be incompatible or incomparable, creating confusion; Even though the firm may be buying third-party information, internal staff must have a feel of the data and processes which the information service provides. 3.1. Surveys conducted by distributing questionnaires to companies about their environmental policies. 3.2. Company visits and interviews with company officers or managers on the firm’s sustainability practices and policies (Kasemir SÃ ¼ess, 2002, p. 21).

Pro Euthanasia Essay Conclusion Example For Students

Pro Euthanasia Essay Conclusion An eighty-seven year old grandmother on a respirator, anewborn child with AIDS, and a father in a coma; all put to deathby respectable doctors with the O.K. of their families. But isit really 3O.K.? Euthanasia, or doctor-assisted suicide, hasbecome as common as jumping off of a fifteen story building ortaking a gun to one1s own head. Certainly society frowns uponsuicide, but yet putting an old lady or a man in a coma to deathis being accepted every day. Society knows that suicide is bad,but euthanasia is even worse. The guilt and blame of a lost lifeis falling on the hands of doctor1s that we are supposed totrust, and even worse, the family members themselves. A doctoris to be known as a healer, not an agent of death. A family issupposed to love and support, not kill and inherit. Every personmakes the light of the world brighter. The world needseveryone1s power and contribution. It1s the power and energy ofthe elderly, and the strength and will of the ill, that give theworld life. Th e light has become very dim with the crime andcorruption in today1s world, we can1t afford to throw lives awaybecause some think they1re meaningless. If we continue to acceptthe merciless killings and suicides of the helpless but powerful,the light will soon burn out. There will be no energy in theworld. Euthanasia and doctor-assisted suicide should not beaccepted or allowed by the government and people of the UnitedStates. Statistics show that seventy-three percent of the U.S. population approved of some form of euthanasia. This is usedconstantly in debates to pass laws for making euthanasia legal. But the people are deceived by this number. When the poll wastaken, the people were asked if they approved of some form ofeuthanasia. There are two forms of euthanasia, active andpassive. It is the passive euthanasia that many people areaccepting, the less harsh of the two. Thats why peoplegenerally say they approve of it. If a separate question wasasked or the people were informed of the difference, we wouldfind that only thirty-eight percent of the population approves ofactive suicide, as used by Kavorkian. So the fact that peopleapprove of euthanasia is irrelevant because only thirty-eightpercent would actually pass a law if they knew that Kavorkian1smethods would be allowed. However, it is said that passive euthanasia, suicide by theremoval of life support, is a long-time practice for hospitalizedpatients. But does this make it O.K?I should think not. Manythings have been accepted and practiced in the world, and many ofthem have become illegal. Not too long ago a teenager coulddrink whenever he wanted. Now we have laws to regulate thedrinking age. This is the same type of thing, something terriblehas going on for too long now. We need to put a stop to thekillings with a law. Just because something has been allowed andoccurring for a long time doesn1t mean that it1s O.K. Also,there is the issue of living wills. A living will is a documentthat protects the right of choice in end of life matters forpatients. And not everyone has a living will when they becomeill even though they don1t want to live through the agony andpain. They just don1t think to make one or plan on being ill andincompetent. But with or without a living will, it1s just notright to end a l ife, even if it1s one1s own. Many think thatthey should be able to decide on their own, but what about theirfamilies. The family will spend the rest of their liveswondering in agony and pain about whether or not a cure wouldhave been found or if the patient would have made it outof the coma. It wouldn1t be right to spread the pain by addingto the fire.But some say, 3Why waste the money and extend thepain and agony by keeping someone on a machine? We need to lookat life in a more positive way. We need to weigh the mattersevenly. What1s more important, the life of a family member ortrying to save money and pain. Clearly it is the life, nothingis more important than that. Approximately one billion dollarsis spent on life support patients annually. But the cost ofkeeping people alive is irrelevant if there is a chance thatthey may be cured or come out of a coma. Agriculture EssaySecondly, just because something is considered to be sinful bythe Bible or in any other religion, doesn1t mean it should be acrime. We live in a democracy where the people, of allreligions, make the laws. They shouldnt be based on anyreligion or religious book. But we1re not talking about the sinof suicide, where talking about euthanasia. Euthanasia isassisted suicide, but isn1t that just a nice name for homicide. Suicide is killing oneself, but how can you assist yourself. Theassistant is another person who is guilty of conspiracy to commitmurder. Laws are already passed against murder. When someonetakes part in euthanasia they1re not going to be on trial forattempted suicide because they weren1t trying to kill themselves,they were taking the life of another. It1s murder and there1s noother way to look at it. Next is the belief that activeeuthanasia should be tolerated in order to save agony and painfor both the family and patient. No one should have to gothrough so much agony over a long period of time. Many think that it1s torture not to help dying patients. Kavorkian accused opposing physicians of being Nazi doctors whotorture and experiment with the poor and unfortunate. However,what is the agony andpain? It is the agony and pain of deathand it has to be faced either way, but it shouldnt be because ofa suicide. We should face the pain and agony with strength anddetermination. The patients need to be determined to hang onand fight for cures. It1s not torture to keep someone alive inhopes of a cure. And if a patient is that ill, then they aren1treally going through that much physical pain, it1s the mental andemotional states of patients that need to be secured. That1s thereason many turn to suicide, they are unhappy with their livesso they begin to decline mentally and emotionally. And as far asexperimenting goes, no experimental drug or procedure is forcedupon any patient, including the elderly and incompetent. Andwhat do they have to lose anyway? Most dont mind usingexperimental drugs because it just may be the cure they1relooking for. There is nothing Nazi about testing drugs andcures in hopes of saving a life. There is no torture or directresult of death. So, in actuality there is no physical agony orpain saved in euthanasia because thats not what the patients aregoing through. It just shortens the mental and physical painthat can be helped in other ways than death. Either way, suicideis no answer to pain.

Pacific War Essays - Pacific Ocean Theatre Of World War II, Japan

Pacific War Pacific War World War II was fought across more land and involved more men than any other war in the history of human civilization. Never before or since has there been a war of such vast importance and of such a large scale. The United States had an absolutely crucial role in the outcome of this war. The U.S. was faced with the colossal challenge of waging two wars at the same time on two very different parts of the planet. The European front was, of course, the more obvious of the two considering the undeniable atrocities and evils that were being committed by Adolf Hitler. Involvement on the European front was inevitable and, generally more accessible for U.S. forces. Less than thirty years before, the United States had fought in Europe, so we were familiar with the terrain and appropriate strategy. However, the Pacific Campaign of World War II presented a unique challenge for United States Armed Forces. Never before had we fought in the South Pacific or even on terrain that resembled that of the Pacific islands. With the Army heavily involved in Europe, in December of 1941 the United States were forced into a war that it was not familiar with nor knew how to fight. Luckily, however, for the U.S., the Marine Corps were the perfect outfit for the kind of fighting need in the Pacific Campaign. Because of their training in land to sea combat, the Marines were uniquely prepared for the war that faced them, whereas, the Army could never have successfully waged war in the Pacific. Without the Marine Corps fighting in the Pacific, the whole war against Japan would not have succeeded. From 1939-1941, at the dawn of Adolf Hitler's war machine in Europe, the United States seemed above the rest of the world. Separated by the vast Atlantic Ocean, the U.S. enjoyed an incredible amount of security. We were almost entirely untouchable from the flames of war rapidly growing in Europe, and the majority of American citizens were happy to not be involved. To them, the European conflict was too far away to have any direct or meaningful impact on their lives. In fact, public opinion did not think that it was even necessary to enter the war at all. However, Roosevelt saw otherwise. He knew that a war in Europe could very well mean a war in the States. Only thirty years before, in World War I, the same kind situation had evolved into the "war to end all wars", where the United States had played a key role. So, Roosevelt desperately wanted and needed to change the minds of nearly the nearly the entire American public; this task presented an almost impossible challenge. With war beginning to be fought in Europe, England was in dire need of any aid they could receive. At the beginning, this aid came in the form of supplies furnished by the United States. Ammunition, food, clothing, and weapons of all kinds were being shipped over to Europe and creating incredible wealth for the American government. Entering the war meant losing a very profitable trade with the desperate allies in Europe. Luckily for England and for Roosevelt, the United States were soon presented with an undeniable reason for entering the war. On December 7, 1941, the Japanese bombed Pearl Harbor. This act of aggression towards America, provided for a perfect entrance into the war, and now the people of America were incited enough to back a full-scale war against Hitler and Japan. However, one huge problem still existed, and that was the problem of a two front war. Many were frightened that the U.S. had taken on a task that was a bit too much for the nation to handle. The Army was the perfect force for fighting the war in Europe. They were trained for the land combat they would face, and had knowledge of the land from World War I. In addition, the Army was already on the move to Europe, so splitting the Army into two different forces for Europe and the South Pacific was out of the question. The only option that the U.S. government had for waging war against Japan was the Marine Corps. Marine units had been stationed in the South Pacific in Australia and Samoa. They only needed to be reinforced. Especially convenient for the United States was the fact that the Marine Corps was perfectly suited for the kind of warfare that would be faced against Japan. Marines are trained specifically for land to sea and sea to land operations. In

Understanding the Glow of Noctilucent Clouds

Understanding the Glow of Noctilucent Clouds Each summer, people who live at high latitudes north and south of the equator are treated to a fantastically beautiful phenomenon called noctilucent clouds. These arent clouds in the normal way we understand them. The clouds were more familiar with are generally made of water droplets that have formed around particles of dust. Noctilucent clouds are generally made of ice crystals that formed around tiny dust particles in fairly cold temperatures. Unlike most clouds that float fairly close to the ground, they exist at heights up to 85 kilometers above the surface of our planet, high in the atmosphere that sustains life on Earth. They may look like thin cirrus that we can see throughout the day or night but are generally only visible when the Sun is no more than 16 degrees below the horizon. Clouds of the Night The term noctilucent means night-shining and it describes these clouds perfectly. They cant be seen during the day due to the brightness of the Sun. However, once the Sun sets, it illuminates these high-flying clouds from below. This explains why they can be seen in deep twilight. They typically have a bluish-white color and look very wispy. The History of Noctilucent Cloud Research Noctilucent clouds were first reported in 1885 and are sometimes linked with the eruption of the famous volcano, Krakatoa in 1883. However, its not clear that the eruption caused them - theres no scientific evidence to prove it one way or another. Their appearance may simply be coincidental. The idea that volcanic eruptions cause these clouds was heavily researched and eventually disproved in the 1920s. Since then, atmospheric scientists have studied noctilucent clouds using balloons, sounding rockets, and satellites. They seem to occur pretty frequently and are quite beautiful to observe. How Do Noctilucent Clouds Form? The ice particles that make up these shimmering clouds are quite small, only about 100 nm across. That many times smaller than the width of a human hair. They form when tiny particles of dust- possibly from bits of micro-meteors in the upper atmosphere- are coated with water vapor and frozen high in the atmosphere, in a region called the mesosphere. During local summer, that region of the atmosphere can be quite cold, and the crystals form at about -100 ° C. Noctilucent cloud formation seems to vary as the solar cycle does. In particular, as the Sun emits more ultraviolet radiation, it interacts with water molecules in the upper atmosphere and breaks them apart. That leaves less water to form the clouds during times of increased activity. Solar physicists and atmospheric scientists are tracking solar activity and noctilucent cloud formation to better understand the connection between the two phenomena. In particular, they are interested in learning why changes in these peculiar clouds dont show up until about a year after UV levels change. Interestingly, when NASAs space shuttles were flying, their exhaust plumes (which were nearly all water vapor) froze high in the atmosphere and created very short-lived mini noctilucent clouds. The same thing has happened with other launch vehicles since the shuttle era. However, launches are few and far between. The phenomenon of noctilucent clouds predates launches and aircraft. However, the short-lived noctilucent clouds from launch activities provide more data points about the atmospheric conditions that help them form. Noctilucent Clouds and Climate Change There may be a connection between the frequent formation of noctilucent clouds and climate change. NASA and other space agencies have been studying Earth for many decades and observing  the effects of global warming. However, the evidence is still being gathered, and the link between the clouds and warming remains a relatively controversial suggestion. Scientists are following up on all the evidence to see if there is a definite link. One possible theory is that methane (a greenhouse gas implicated in climate change) migrates to the area of the atmosphere where these clouds form. Greenhouse gases are thought to force temperature changes in the mesosphere, causing it to cool down. That cooling would contribute to the formation of ice crystals that make up the noctilucent clouds. An increase in water vapor (also due to human activities that produce greenhouse gases) would be part of the noctilucent cloud connection to climate change.
