The Dust Veil Environmental Disaster of AD 536

According to written records and supported by dendrochronology (tree ring) and archaeological evidence, for 12-18 months in AD 536-537, a thick, persistent dust veil or dry fog darkened the skies between Europe and Asia Minor. The climatic interruption brought by the thick, bluish fog extended as far east as China, where summer frosts and snow are mentioned in historical records; tree ring data from Mongolia and Siberia to Argentina and Chile reflect decreased growing records from 536 and the subsequent decade. The climatic effects of the dust veil brought decreased temperatures, drought, and food shortages throughout the affected regions: in Europe, two years later came the Justinian plague. The combination killed perhaps as much as 1/3 of the population of Europe; in China, the famine killed perhaps 80% of people in some regions; and in Scandinavia, the losses may have been as much as 75-90% of the population, as evidenced by the numbers of deserted villages and cemeteries. Historical Documentation The rediscovery of the AD 536 event was made during the 1980s by American geoscientists Stothers and Rampino, who searched classical sources for evidence of volcanic eruptions. Among their other findings, they noted several references to environmental disasters around the world between AD 536-538. Contemporary reports identified by Stothers and Rampino included Michael the Syrian, who wrote: [T]he sun became dark and its darkness lasted for one and a half years [...] Each day it shone for about four hours and still this light was only a feeble shadow [...] the fruits did not ripen and the wine tasted like sour grapes. John of Ephesus related much the same events. Prokopios, who lived in both Africa and Italy at the time, said: For the sun gave forth its light without brightness, like the moon, during this whole year, and it seemed exceedingly like the sun in eclipse, for the beams it shed were not clear nor such as it is accustomed to shed. An anonymous Syrian chronicler wrote: [T]he sun began to be darkened by day and the moon by night, while the ocean was tumultuous with spray, from the 24th of March in this year till the 24th of June in the following year... The following winter in Mesopotamia was so bad that from the large and unwonted quantity of snow the birds perished. A Summer Without Heat Cassiodorus, praetorian prefect of Italy at the time, wrote: so we have had a winter without storms, spring without mildness, summer without heat. John Lydos, in On Portents, writing from Constantinople, said: If the sun becomes dim because the air is dense from rising moisture—as happened in [536/537] for nearly a whole year [...] so that produce was destroyed because of the bad time—it predicts heavy trouble in Europe. In China, reports indicate that the star of Canopus could not be seen in as usual in the spring and fall equinoxes of 536, and the years AD 536-538 were marked by summer snows and frosts, drought and severe famine. In some parts of China, the weather was so severe that 70-80% of the people starved to death. Physical Evidence Tree rings show that 536 and the following ten years was a period of slow growth for Scandinavian pines, European oaks and even several North American species including bristlecone pine and foxtail; similar patterns of ring size decrease are also seen in trees in Mongolia and northern Siberia. But there seems to be something of a regional variation in the worst of the effects. 536 was a bad growing season in many parts of the world, but more generally, it was a part of a decade-long downturn in climate for the northern hemisphere, separate from the worst seasons by 3-7 years. For most reports in Europe and Eurasia, there is a drop in 536, followed by a recovery in 537-539, followed by a more serious plunge lasting perhaps as late as 550. In most cases the worst year for tree ring growth is 540; in Siberia 543, southern Chile 540, Argentina 540-548. AD 536 and the Viking Diaspora Archaeological evidence described by Grà ¤slund and Price shows that Scandinavia might have experienced the worst troubles. Almost 75% of villages were abandoned in parts of Sweden, and areas of southern Norway show a decrease in formal burials—indicating that haste was required in interments—up to 90-95%. Scandinavian narratives recount possible events that might be referring to 536. Snorri Sturlusons Edda includes a reference to Fimbulwinter, the great or mighty winter that served as a forewarning of Ragnarà ¶k, the destruction of the world and all of its inhabitants. First of all that a winter will come called Fimbulwinter. Then snow will drift from all directions. There will then be great frosts and keen winds. The sun will do no good. There will be three of these winters together and no summer between. Grà ¤slund and Price speculate that the social unrest and sharp agrarian decline and demographic disaster in Scandinavia may have been a primary catalyst for the Viking diaspora—when in the 9th century AD, young men left Scandinavia in droves  and sought to conquer new worlds.   Possible Causes Scholars are divided concerning what caused the dust veil: a violent volcanic eruption—or several (see Churakova et al.), a cometary impact, even a near miss by a large comet could have created a dust cloud made up of dust particles, smoke from fires and (if a volcanic eruption) sulfuric acid droplets such as that described. Such a cloud would reflect and/or absorb light, increasing the earths albedo and measurably decreasing the temperature. Sources Arrhenius B. 2012. Helgà ¶ in the shadow of the dust veil 536-37.

MNGT 5000 May 14, 2010 Term Paper There are many issues that companies face every day that could potentially be managed in a different way. The issue that I would like to review is an issue that is in the forefront of the news these days. It is hard to say when there might be some sort of resolution to this issue, based on the size and impact to the environment and economy. We will write a custom essay sample on Mngt 5000 Term Paper or any similar topic only for you Order Now The most recent issue occurred on April 20, 2010. This was when the Deepwater Horizon oil rig exploded and sunk into the Gulf of Mexico 2 days later. Along with this explosion, there were 11 people reported missing and are assumed dead. The larger problem that British Petroleum has experienced since this explosion is a blow out preventer (BOP) that failed. This failed BOP has caused a horrible oil leak that is gushing from the ocean floor. The initial estimates were that the leak would be around 1,000 barrels or 42,000 gallons per day. This number has since skyrocketed from the initial estimates. As of May 13, this number is now thought to be as high as 70,000 barrels per day, or 2,940,000 gallons. With the amount of oil that is leaking into the Gulf of Mexico from this incident give it the potential to be the worst oil spill in US history. The previous largest oil spill in US history was the Exxon Valdez Oil Spill that occurred on March 24, 1989. As a comparison, the Valdez spill lost 250,000 barrels of oil, or 10,500,000 gallons. It was not until 1992 that the clean up from this spill was completed. From the estimated numbers, the current spill will eclipse the Valdez spill in only a matter of days. Given the fact that the Valdez spill took 3 years to clean up, we can only speculate as to how long it might take to clean up the effects of the Deepwater Horizon. The main problem that BP is immediately faced with is how to control and stop the Deepwater Horizon leak. There have been many suggestions as to what approach they should take. British Petroleum has had to utilize the planning process and try to implement several different strategies since April 22, 2010. While the typical planning process might take several weeks or months, BP had to speed this process up. Their goal is to try and minimize the impact to the Gulf of Mexico and the surrounding environment. Planning is necessary to help drive a structured process for making decisions about the goal they are trying to reach. There are 6 main steps involved in a formal planning process. The first step in the planning process is situational analysis. This first step most likely started for BP on April 20th after the explosion happened. This is when all relevant information about the plan is gathered, interpreted and summarized. For this situation, it most likely included studying past events, the current conditions and trying to forecast future events. The next step in the planning process is to review alternative goals and plans that might have been identified through the situational analysis. A goal is a certain target that is set by a manager that they hope to reach. The alternative goal that BP needs to try to achieve as quickly as possible is to stop the leak that is gushing from the ocean floor. The book Management: Leading Collaborating in the Competitive World outlines a very helpful acronym to ensure you gather certain qualities in the goals you set. The acronym identified is SMART. This stands for Specific, Measureable, Attainable, Relevant and Time-bound. There are parts of this acronym that are a little more sensitive for BP than some of the other pieces. The time bound is the part that sticks out in my mind. The longer it takes to contain the leak from the ocean floor, the larger the impact to the environment and to BP financially. As of May 13, the oil has been leaking from the Deepwater Horizon site for 24 days. It appears that BP has come up with many alternative plans to try and address and contain the oil leak that the failed BOP has created. Next we will review the different plans that BP has established and how some of them have been working so far. A plan is defined as how the management staff plans to achieve the outlined goals. BP has presented several plans that they will use to try and achieve their goal. The first plan that they will try to implement is to lower a containment box over the leak that will then funnel the oil to the surface and into an oil tanker. This will be the quickest option that they can try to put in place to stop the leak. Another option that they will try to implement at the same time is to drill a relief well, but this could take up to 3 months to complete. Once the alternatives have been reviewed, we move to step three which is to evaluate the goals and plan. All of this planning has to be completed in a very tight time frame for BP, because as the time passes, the oil continues to leak. During this step, management will review the advantages and disadvantages of the alternative goals and plan from step 2. The drilling of a relief well has a huge disadvantage due to the time frame. This step also includes prioritizing and potentially eliminating some of the goals. Step 4 is the Goal and Plan Selection. After having reviewed and prioritized the goals in the last step, this is where the decision will actually be made on which goal and plan is most feasible. After the selection has been made, the following step is to implement plans to achieve the goals that have been outlined. As of May 7, British Petroleum has started to implement their plan of lowering a container over the leaking well. Once everything is implemented, the final step is to monitor and control the work that is being done. The container was successfully lowered into place, however ice crystals started to form and blocked the pipe that would deliver the oil to the surface. BP has now had to resort to some of their back up or alternative plans. Some other ideas that have been presented in this process include using a smaller containment dome, shooting junk into the well to clog the hole, and siphoning the oil into a tanker at the surface. With these different plans in place, BP will have to ensure that they have a good strategy if another alternate fails. The definition of strategy is a pattern of actions and resource allocations designed to achieve the organization’s goals. Planning and strategy go hand in hand. BP will need to use some strategic management in dealing with this situation. Strategic management is basically a strategic planning process that has six major steps. The first step is to establish a mission, vision and goals. The mission is short statement that describes the purpose of the organization. The vision is what the organization hopes to accomplish in the future. BP has their company mission and vision statement listed on their site as their values. The sites states â€Å"BP wants to be recognized as a great company – competitively successful and a force for progress. We have a fundamental belief that we can make a difference in the world. We help the world meet its growing need for heat, light and mobility. We strive to do that by producing energy that is affordable, secure and doesn’t damage the environment. BP is progressive, responsible, innovative and performance driven. † The second step in this process is to do an analysis of external opportunities and threats. This includes understanding the different forces that might affect the company’s mission and vision. This is a unique situation for BP, due to the fact that they are trying to live up to their values, while trying to prevent an environmental disaster that could potentially tarnish their name for quite some time. After reviewing external factors, step 3 is to complete an analysis of internal strengths and weaknesses. There are many aspects to an organization that can be reviewed a couple of key parts to be reviewed would be resources available and core competencies. Resources can fall into two categories, tangible and intangible. Steps 2 and 3 provide a good foundation of information for step 4, which is SWOT Analysis and Strategy Formulation. Once the SWOT analysis is complete, there are several different strategies to consider based on the type of business that is in operation. For BP and this situation, I would think that they would need to implement a functional strategy. Once the type of strategy has been decided upon, step 5 is strategy implementation. During this step, BP would need to ensure that the strategy is being implemented efficiently and effectively. Once implemented, this takes us to the final step, which is strategic control. I believe this control will not be in place until the leak has been contained. In this final step, typically there is a system to help support management in evaluating how the organization is doing with the strategy. Overall, BP has an enormous task that they are faced with. It will take good planning and strategy to resolve the issue as quickly as possible. They are faced with having to contain one of the largest oil spills in US history. It is hard to accurately measure the true amount of oil that is leaking from the well; however there are several estimates of how much oil is leaking per day, ranging from 1000 to 70,000 barrels. As of May 13, 2010, BP has had to resort to alternate plans due to their initial attempt failing. It will be interesting to watch the news and see how BP continues to manage the situation. It is almost guaranteed that the government will intervene at some point, possibly by implementing new laws around off shore drilling. We can only hope that the impact to the environment is not too great, but there have already been reports of dead animals and tar balls washing ashore. It is hard to think that there would be no impact with so much oil leaking into the ocean. I still remember the images from the Exxon Valdez oil spill in 1989. I can only imagine we will start to see some of the same images in the future from the Deepwater Horizon spill. Let’s hope that BP’s management staff has all the tools necessary to have a strong plan in place to rectify this problem. Bibliography Robertson, C Lipton, E (2010, April 30).

Main Characteristics of Hinduism free essay sample

The majority of Hinduism is henotheistic- worship of one God while acknowledging the existence of other Gods. Hinduism concepts teach a cycle of life. From birth to rebirth can happen 84 million times because there are 84 million species. All living beings are created by God and has a soul known as Hindus. It identifies one deity and acknowledges the remaining Gods and Goddesses as part of the supreme God. Henotheistic religions are known to be very tolerant and diverse. B. G. Tilak (1995, July 2) at the Supreme Court in India quoted, the true definition of Hinduism: Acceptance of the Vedas with reverence; recognition of the fact that the means or ways to salvation are diverse; and the realization of the truth that the number of gods to be worshipped is large, that indeed is the distinguishing feature of the Hindu religion. † Hinduism is not regulated by a central institution. It welcomes other religions as one of the many paths to redemption and is not in favor of organized effort to convert someone to a religious faith. We will write a custom essay sample on Main Characteristics of Hinduism or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Throughout its history, scholars, kings and emperors, seers and sages have contributed to modifying and molding aspects to suit the social and intellectual requirements or the times.Many Hindus believe Hinduism is not a religion but more so a way of life. Religion is imbedded in the life of Hinduism. According to the Hinduism principles life and religion go hand and hand. Religion is everywhere dominating, regulating life with divine existence making for a purposeful and meaningful life. Each Hindu person is free to follow a path they would like but underneath the mind the religion remains and influences the actions and decisions made. V. Jayaram (2009, May 26) proposed that religion is: â€Å"According to Hinduism, religion is not separate from living. It is living itself. God does not exist in temples and sacred places only. Going to the temples is a good practice, but that is not the only way to worship God. God does not exist in temples alone, in some particular alter or sacred place. † The Hinduism lifestyle urges individuals to accept everyday as self-realization. As stated by (V. Jayaram, 2009) every activity that we perform while living and every aspect of life that we know and deal with becomes means to realize God. Life is a time to discover your hidden self. Hinduism has three symbolic essentials: roots, for meditation on Vedas; ethics, focusing on karma and ignorance of self.The most well-known Hindu concepts are Advaita, Samkhya, Vedanta and Yoga. The most sacred scriptures of Hinduism is the Vedas. According to the Hinduwebsite (V. Jayaram, 2009), some people say that all human knowledge is available in the Vedas in symbolic form and that the knowledge of all our discoveries and inventions is already contained in the Vedas. The Vedas are religious texts full of spiritual knowledge and often thought of as the basis of Sanatana Dharma. They are a celebrated set of ancient hymns that was not written until the first millennium B-C-E. The text contains four parts established over time: Samhitas, which are hymns of worship; Brahmanas, instructions on how to carry out ritual sacrifices to the Gods; Aranyakas, literature by inhabitants meditating in the woodlands; and Upanishads, based on teachings from superior spiritual leaders. The Vedic scriptures go beyond human time being as significant today as they were thousands of years ago. One of the most fascinating aspects of Hinduism is the yoga, that has influenced many people no matter what religion they practice. Yoga started in Indus-Sarasvati civilization in northern India about 5000 years ago.The Rig Veda contains the first original reference to yoga. Although the development of yoga basics has been a long process with many influences, the overall path of the discipline can be divided into classical, post-classical and modern periods (And Then There Was Yoga-The Yogic Story, 2009, par 4). The various types of yoga can be so different and serve different purposes . Bhakti Yoga concentrates on devotion, emotional bond and love of God. This yoga has been used prior to the fifth century BC and officially has nine forms: Sravana, Kirtana, Smarana, Padasevana, Archana, Vandana, Dasya, Sakhya and Atmanivedana.Karma (deeds) yoga, dating as far back as 800 BC promotes good behavior and positive actions. Practicing karma yoga consists of doing good, selfless deeds that allow for goodness. This yoga is performed in unity with the Devine. Around 5000 BC Ashtanga yoga was created by Patanjali Yoga Sutra. It involves paying attention to the eight limbs, that are: Yama- moral code; Niyama- disciplines; Asana- posture; Pranayama- breathing; Prayahara- removal of senses; Dharana-concentration; Dhyan-meditation; Samadhi- salvation. Top Yoga Techniques For A Healthy Life (2009) suggest Jnana yoga for the brain, which means: â€Å"Jnana yoga is yoga that focuses on knowledge. There are seven stages to Jnana, involving study, self-realization, desire, protection of the mind, developing indifference to objects, letting the world appear like a dream, non-attachment to the world, bliss and knowledge of truth. † The United States mostly practices Hatha Yoga which applies to the modern period. In the 1800’s early 1900’s Yoga masters started traveling around the world. T.
