The Boon Or Bane Of Global Warming Environmental Sciences Essay

The Boon Or Bane Of Global Warming Environmental Sciences Essay The stratosphere ozone (o3) is a product of billions of years of the photochemical process catlalyzed by the solar radiation . The ozone screen provides a shield for living creatures by filtering out dangerous ultra-violet rays from sunlight . ultra violet radiation causes sun burn , skin cancer , cataracts and can suppress the immune system . Since 1973 it has been increasingly recognized that the ozone umbrella is being ripped off by the industrial activities of man which release chemicals like chlorofluorocarbons (CFCs) The main problem with the CFCs is their long life in the atmosphere ranging from 75 to 125 years . Also one molecule of CFC can destroy 1,00,000 molecules of ozone . Also rockets which take off vertically carry ozone killers (Chlorine containing chemicals and nitrogen oxides ) Eg : The American Delta booster, the authors rate it as a second ozone killer which destroys 8 million tonnes of the earth shielding gas during every take-off SOLUTION Coming to the question of stopping launchings of space ships to obviate thinning of the ozone layer , the soviet experts are of the view the problem can be tackled by taking positive steps like minimizing production of ozone-killing chemicals , banning solid fuel fired rockets , and setting international restrictions for the frequency of launches . A BRITISH ORGANIZATION , Ozone Help (OH ) has come out with a programme to produce ozone in the upper atmosphere . A solar powered machine is carried to high altitudes by balloons over the antartica , where the ozone depletion has reached its highest . This ozonator is a simple electronic unit about the size of a large microphone and generates a charge of more than 15,000 volts . When this charge is emitted into the air , it produces a significant amount of ozone by converting the oxygen of the air. GLOBAL WARMING (due to greenhouse gases ) The large scale burning of fossil fuels in modern industry and transport systems increases the concentration of greenhouse gases such as CO2 , O3 , CH4, CFC3 and N2O in the atmosphere . These greenhouse gases allow suns rays to penetrate the earth surface but retard the return flow of the infra-red radiation. Thus the suns heat would be trapped near the earths surface, raising the earths surface temperature over a period of time. Among all the gases CO2 alone plays a major role in creating greenhouse effect. There are many reasons to be cautious about accepting CO2 as the causative agent if there really is warming. This is highlighted by 2 papers published in March 2008. Scafetta and West showed that up to 69% of observed warming is from the sun and Ramanathan and Carmichael show that soot has 60% of the warming power of CO2 The fluctuations in the composition of the atmosphere and changes in the temperature over the past two lakh years can be determined by analysis of tiny air bubbles trapped in ice that has accreted year by year in arctic and Antarctic. All scenarios on global warming show that significant climate change will occur over a period of time. There are many other issues of environmental concern too like radioactive fallouts , phenomenon of acid rain , large scale deforestation and large scale use of pesticides and chemical fertilizers in modern agriculture and so on . Here are some ways for the prevention of global warming Clean or replace filters on your furnace and air conditioner Cleaning a dirty air filter can save 350 pounds of carbon dioxide a year.. Do not leave appliances on standby Use the on/off function on the machine itself. A TV set thats switched on for 3 hours a day (the average time Europeans spend watching TV) and in standby mode during the remaining 21 hours uses about 40% of its energy in standby mode Plant a tree A single tree will absorb one ton of carbon dioxide over its lifetime. Shade provided by trees can also reduce your air conditioning bill by 10 to 15%. Encourage the switch to renewable energy Successfully combating global warming requires a national transition to renewable energy sources such as solar, wind and biomass. These technologies are ready to be deployed more widely but there are regulatory barriers impeding them Try car sharing Need a car but dont want to buy one? Community car sharing organizations provide access to a car and your membership fee covers gas, maintenance and insurance. Is Global Warming Bad? The IPCC 2007 Reports Suggest There Will be More Losers than Winners with Warming. The IPCC process includes many unlikely scenarios. These worst-case estimates also have associated impacts, from benign to worst-case. Thus we get the 5% worst impacts that have a 5% chance of happening (a combined 0.25% likelihood) equally discussed with benign changes that are reasonable to expect. By the time summaries are written, and press releases, only the bad effects are presented.   This leads to a gross exaggeration of the problems. Global Warming Will Actually Have More Winners then Losers. Throughout the history of human life, the Earths livability has always been better when the climate has been warmer than cooler. Human populations have expanded the most when the Earth warmed and turned greener, whether during the middle ages or during the last 2 decades. Whether it is a   fish in the ocean, a shrimp in an aquaculture pond, or a bean on a   vine, it will grow faster when it is warmer, all things being equal. Humans will   be quick to take advantage of a warmer climate and to adjust if it gets too warm in an area. More crops grow where it is warm or hot than in frozen ground, and CO2 is a primary food of plants basic facts that   seem forgotten. Even now, NASA satellites show that the Earth has become 6% greener as the world has warmed over the past 20 years (In the laymans approach, ozone depletion and global warming is mostly the same thing . However if you take a closer look youll know they are completely different . Although the two are different, activities leading to one always have some impact on the other ) Read more: Difference Between Ozone Depletion and Global Warming | Difference Between | Ozone Depletion vs Global Warming http://www.differencebetween.net/science/nature/difference-between-ozone-depletion-and-global-warming/#ixzz1AiNbKbQO Facts about climate change This chart looks ominous until put into the context that the average temperature for 1901-2000 is 13.9C (57.0F), so we are talking about a change from about 13.5 to 14.3 C or 56.3 to 57. 7 F. Not only is Earths surface warming, but the troposphere the lowest level of the atmosphere, where weather occurs is heating up too, U.S. and British meteorologists reported The EPA is set to regulate greenhouse gases next year for the first time, after the Supreme Court ruled in 2007 that it could treat heat-trapping gases such as carbon dioxide as pollutants.EPA spokesman Brendan Gilfillan responded: The commonsense and transparent steps weve taken are already proving doomsayers wrong, as evidenced by the fact that 98 percent of states have stated theyre in a position to comply (times of india) Democrats established the committee in 2007, after taking control of the House. At the time, House Speaker Nancy Pelosi, a Democrat, called global warming possibly the greatest challenge of our time, setting at risk our economy, environment and national security. Scientists across the globe are toiling to perfect newer sources of energy that would end reliance on fossil fuels and threat of global warming. Those at citybased National Environmental Engineering Research Institute (Neeri) have joined the pack. They have developed a process of producing biofuel from four different species of micro-algae (plants that cant be seen with naked eye). The climate is changing. The earth is warming up, and there is now overwhelming scientific consensus that it is happening .. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. Many have agreed that climate change may be one of the greatest threats facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities in weather patterns. Climate change, in the absence of mitigation policies would in all likelihood lead to: 1 Possible disappearance of sea ice by the latter part of the 21st century 2 Increase in freqency of hot extremes, heat waves and heavy precipitation 3 Increase in tropical cyclone intensity 4 Decrease in water resources due to climate change in many semi-arid areas, such as the Mediterranean Basin, western United States, southern Africa and north-eastern Brazil. 5 Possible elimination of the Greenland ice sheet and a resulting contribution to sea level rise of about 7 metres. Without mitigation future temperatures in Greenland would compare with levels estimated for 125,000 years ago when palaeoclimate information suggests 4 to 6 m of sea level rise. 6 Approximately 20 to 30% of species assessed so far are likely to be at increased risk of extinction if increases in global average warming exceed 1.5 to 2.5 degrees C. In Africa, by 2020, between 75 and 250 million people are projected to be exposed to water stress due to climate change, and in some countries yields from rainfed agriculture could be reduced by up to 50%. The impacts of climate change would be disproportionately severe on some of the poorest regions and communities of the world. My own analysis suggests that at least 12 countries are likely to tend towards becoming failed states and communities in several other states would show potential for serious conflict due to scarcity of food,, water stress and soil degradation. UN Summit on Climate Change, 22 September 2009 STATEMENT OF DR. R. K. PACHAURI Chairman, IPCC Director General, The Energy and Resources Institute Director, Yale Climate and Energy Institute Warming of the climate system is unequivocal as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global sea level, and that Most of the observed increase in temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG concentrations. In the twentieth century average global temperature increased by 0.740 C while sea level rise resulting from thermal expansion of the ocean and melting of ice across the globe amounted to 17 cms. With this increase the Maldive Islands with land surface barely a metre or two above sea level, every storm surge and major upwelling of the seas represents a major danger to life and property. But this is not all. Climate change is already resulting in an increase in the frequency, intensity and duration of floods, droughts and heat waves. Precipitation has increased significantly in eastern parts of North and South America, north ern Europe and northern and central Asia, whereas it declined in the Sahel, the Mediterranean, southern Africa and parts of south Asia. Globally the area affected by drought has increased since the 1970s If we take no action to stabilize the concentration of greenhouse gases in the atmosphere, then average temperature by the end of this century would increase anywhere from 1.1 degrees to 6.4 degrees C. The world is increasing its emissions at a rate that may take us to the upper end of the range projected, which implies a total increase in these two centuries of over 7 degrees C, that is, over 12 degrees Fahrenheit. Yet between 1970 and 2004 global GHG emissions increased by 70% and carbon dioxide by 80%. We must halt this unacceptable trend. It is heartening that the G8 leaders have recognized the broad scientific view of limiting increase in global average temperature to 2 ° C. But, we have clearly specified that if temperature increase is to be limited to between 2.0 and 2.4 ° C, global emissions must peak no later than 2015. That is only six years from now. And the 2.0 ° ceiling too would lead to sea-level rise on account of thermal expansion alone of 0.4 to 1.4 meters. This increase added to the effect melting of snow and ice across the globe, could submerge several small island states and Bangladesh. CONCLUSION Like Michael Jackson said Heal the world make it a better place for you and for me and the entire human race . There are people dying if we care enough for the living , make it a better place for you and for me While this is just the tip of the iceberg, many, many issues need addressing regarding the extinction of plant and animal species, polar bears and their natural habitat and as times of india has mentioned that the lakes are heating faster than the air There are many such questions that need to be answered. .It is more important now than ever before to pull heads out of the sand and make a change for the better to our mother earth before it becomes too late. The earth is something we borrowed from our future generation hence we must do what we can in our capacity to preserve it . where the question of global warming arises it is seen as a detriment to us hence we should take measures to counter its growth or to our peril .

Three Mile Island Case :: essays research papers

5a) If I were on the School Board I would not have agreed to the issue framed for the arbitrator. I believe that the issue was not neutral, rather that it favored the association and Ms. Kimball. Statements in the issue such as, â€Å"...when the grievance absented herself from work for illness...†, support Kimball’s argument. In the Position of the School District section of the handout, the School Board states that when Kimball called in to report the absence she simply informed the district â€Å"that she would not be in.† In my opinion, this should have replaced the prior statement of her calling out â€Å"due to illness†.   Ã‚  Ã‚  Ã‚  Ã‚  I also think that the School Board should not have agreed to the issue starting with the question â€Å"Was the School District wrong...† this automatically influences the arbitrator to question the School Board’s decision. The issue could have either been changed to impose the question of Kimball being wrong, or to a question of a neutral sort.   Ã‚  Ã‚  Ã‚  Ã‚  If I were the School Board I would have proposed this issue to the arbitrator:   Ã‚  Ã‚  Ã‚  Ã‚   Should Denise Kimball be paid for Tuesday and Wednesday, April 3 and 4, after   Ã‚  Ã‚  Ã‚  Ã‚  calling to inform her place of employment â€Å"that she would not be in† due to the   Ã‚  Ã‚  Ã‚  Ã‚  Three Mile Island Incident of March 30, 1979? I feel that this issue is not only factual but puts weight in the School Board’s argument.   Ã‚  Ã‚  Ã‚  Ã‚  5b) Although I do not believe that the issue to the arbitrator was fair to the School Board, if I were the arbitrator, I would have ruled for the association and Ms. Kimball. I feel based on the severity of The Three Mile Incident and the fact that Kimball had a legitament note from a physician with a diagnosis of â€Å"environmental stress, emotional stress, and anxiety†, that she should be paid for the days missed. This right is upheld by the Applicable Pennsylvania Statutes: School Laws of Pennsylvania under Section 1154, which is covered in the handout.   Ã‚  Ã‚  Ã‚  Ã‚  The School Board’s argument of â€Å"she was not sick on the days in question† covered in the Position of the School

How Does Architecture Create Memories?

Memory AND ARCHITECTURE How does architecture make memories? Should it non be the most of import undertaking of it beyond signifier and map? Introduction Architects from rather some clip have started speaking about making â€Å"a sense of a place† by supplying an environment which is experiential and has a sense of belonging. â€Å"Sense of a topographic point goes manus in manus with making memories† ( Lehmon, 2008-2010 ) as written by Maria Lerena Lehmon in her article â€Å"sensing architecture† . Further lucubrating on the subject she says our memory of events may depend upon a strong sense of topographic point, and by extension, our sense of topographic point may be influenced by the unity of memories formed at that place. The memory of an event or a occurrence ever has a environing background or a physical built around it. If this background has a peculiar character or a sense attached to it so it helps the memory of that event/experience grow stronger. The term â€Å"physical background† is non limited to the difficult physical stuffs used but besides to the infinites they generate and the manner our senses respond towards these assorted elements and the manner these stuffs and infinites alter and determine our centripetal perceptual experience. Why is it easier to retrieve certain paths as compared to the others, is it because they have less figure of bends or is it merely because one can tie in with them more easy? I live in Jasola Vihar in New Delhi and why is it so that every clip I guide person to my place I end up stating them that I stay in the â€Å"grey DDA flats near Appolo Hospital† ? It’s an unnoticed attempt of making a sense of association with the milieus, be it a land grade or a curious character of a topographic point ( sense of a topographic point ) . It is now in the universe of globalization that we, in the name of braking boundaries have decided to allow travel of our individualities as good.With the planetary architecture picking up its gait it is going hard to separate between topographic points and hence the formation of a strong association and an irremovable memory of topographic point is being put at serious hazard. Here is an illustration of Tokyo ( left ) and Chicago ( right ) , two metropoliss from the opposite corners of the universe yet difficult to separate. Fig. 1 Fig. 2 ( Anon. , 2014 ) ( Anon. , 2014 ) Here is another illustrations of Venice ( left ) and Banaras ( right ) , two metropoliss holding certain characteristics in common but yet they stand with independent individualities and honest to the memories and associations attached to them. Fig. 3 Fig. 4 ( ( ALAMY, 2014 ) ) ( Sharma, 2010 ) NEED IDENTIFICATION Human memory has been the reply bank to some basic inquiry related to our being every bit good as to some complex inquiries related to our journey through ages. â€Å"Memory† has ever been of import in the universe of treatments non merely because it is the â€Å"record keeper† of events but besides because it is a supplier of individuality. It is our memory that tells us where we belong and where we come from. Architecture on the other manus has ever been one of the strongest defenders and projectors of a certain individuality ( belonging to a certain clip and topographic point ) . Therefore this survey is meant to place and convey out the elements of the built that really formulate a certain association and a sense of perceptual experience amongst the experiencers, taking us to admit the strength of architecture in traveling beyond signifier and map and arousing our centripetal perceptual experiences for supplying us with a memory of the â€Å"self† . Scope The survey shall cover the usage of the centripetal variety meats in the apprehension of different infinites both at the colony degree and at single infinite degree. It shall be a comparative survey between different places/spaces on the personal interview footing sing topographic points in India. Restriction Memories of topographic point are normally subjected to personal perceptual experiences and readings and hence to generalize a decision is in uncertainty. A figure personal interviews will be the best possible agencies to average out a sense of a topographic point and to enter how certain characters of the same topographic point are in common in the memories of different people. Methodology The bing literature predominating on memory and architecture shall be identified, gathered and reviewed. The reappraisal shall with an armory of theories and thoughts that have been contemplated on the topic in the yesteryear. The survey shall so be applied to the Indian context. The acquired cognition through the literature study shall be used to place peculiar instances in India taking an illustration of an old town of Bilgram and the metropolitan Delhi. A close survey of both the colony shall be done at the macro and micro degree saying illustrations that can clearly reflect the theories derived from the literature study. The instance surveies shall so be closely looked upon and scrutinised and be written about. Finally the subject of memory and architecture shall be discussed with a practicing designer and his/her positions shall be acknowledged and documented. All consequences learnt shall so be compiled with a successful effort to deduce to a decision in the terminal. HUMAN MEMORY AND ITS WAYS WHAT IS MEMORY? The mental module entering the past experiences based on the mental procedure of acquisition, retaining and remembering ( Oxford lexicon ) . But is this it? Let us get down with a brief apprehension of the types of memories that exist and the procedure of their formation. Fig. 5 ( mastin, 2010 ) What we by and large perceive as memory in our twenty-four hours to twenty-four hours lives is really the long term memory but there besides exist the centripetal memory and the short term memory, which normally go unnoticed by us in the haste of our mundane lives. Every event/incidence goes through a enrollment procedure in our sensory and short term memory foremost, before being stored for good in our long term memory. Therefore the stronger the impact of an event on our sensory and short term memory the better are the opportunities of that event being remembered for a life time ­Ã‚ ­ . SENSORY MEMORY Centripetal memory is what we relate to ‘perception in an instance’ . It is the shortest signifier of memory generated at a automatic rate through any of our five senses of odor, sight, hearing, gustatory sensation and touch. The clip span of such memory is non more than 300-500 msecs and upper limit to a 2nd ( rare instances ) and therefore it is more of an inherent aptitude based memory. Our encephalon is trained to register merely a selected portion of the information which has the opportunities of being utile in future and therefore most of the clip our centripetal memory goes live. For an event or an experience to hold an impact on our memory at the sensory ( instantaneous ) gait it needs to hold a really strong contact with our either of our five senses. ( mastin, 2010 ) Like for illustration: when you do a trek to Kheerganga through those thick woods and the soft slippery Shivalik mountains of Himachal Pradesh you can ne'er think what will come next and so all of a sudden you enter into this huge vacant vale perfectly untasted and pure, surrounded with immense mountains all about and you stand in the in-between lick a pinpoint of dust. Or when in the metropolis of Ajmer, you decide to go all the manner up to the Taragarh garrison, off from the pandemonium and the hustle hustle of the metropolis. You reach the top and so you look back, down onto all the flashing visible radiations and a immense nothingness ( the lake ) amongst them, the contrast and the astonishment, can non be ignored. Or when you enter the edifice of the National Institute Design ( Ahmedabad ) through its low tallness reception/gallery/display country and you all of a sudden happen yourself into this immense courtyard where the edifice merely opens itself to you, the courtyard filled with cold visible radiation and a immense tree turning right in the center of it. Or for that affair the same edifice pull offing to keep the sensitiveness towards the natural environment to an extent that we can happen alien birds like Inachis ios rolling in the campus like pigeons in Delhi. Such experiential topographic points do non necessitate a long procedure of recollection and acquaintance to develop an association and a lasting topographic point in 1s memories. These brushs generate a sudden daze, opening themselves as a surprise box and acquire absorbed by 1s centripetal perceptual experience, immediately lodging to his/her memory. But the restriction of such a memory is that it can merely be generated with a first-hand experience as it requires the response of our senses in the purest signifier which can merely be generated when we ourselves are physically involved in the event ( shabeeb, 2014 ) Short-run MEMORY ( WORKING MEMORY ) The following phase of our memory procedure is the short-run memory or the on the job memory, working on the footing of impermanent callback. It is the memory formation working analogue with the apprehension of the event. We can take reading as an illustration. When we read, in order to understand the sentence we are reading we need to retrieve the old sentence we merely read. Brain is fundamentally remembering the prequel and understanding the subsequence at the same clip, but the encephalon can be forced to switch the sentences to the slot for long term memory be insistent readings or by calculated effort to consciously retrieve the reading through concentration and apprehension. ( mastin, 2010 ) This is how our encephalon processes pilotage, be it through pages or through roads. So why is it that we remember certain paths clearly and be given to bury certain once more and once more? There can be two replies to this inquiry: Either we travel a certain path more often so the repeat or the timely reoccurrence of the same event makes it stick to our long term memory. Or while going through certain paths we witness such landmarks which merely can non travel unnoticed and they at the same time form a mental map of our path. Metro Stationss in Delhi are a perfect illustration of this. They non merely ease the users of the tube but besides end up steering many going on the roads. The cut to Preet Vihar where my uncle corsets is right opposite the pillar figure 100 of Anand Vihar metro line. Now how do I retrieve this? Equally shortly as I made the bend into Preet Vihar through that dense, confounding route of Anad Vihar my encephalon tried to at the same time remember the most high and the closest thing around which my sense of sight absorbed. The pillar figure 100, written with black in a xanthous circle on a gray concrete pillar. Long-run Memory Long-run memory is, evidently plenty, intended for storage of information over a long period of clip. Despite our mundane feelings of forgetting, it seems likely that long-run memory really decays really small over clip, and can hive away a apparently limitless sum of information about indefinitely. Indeed, there is some argument as to whether we really of all time â€Å"forget† anything at all, or whether it merely becomes progressively hard to entree or recover certain points from memory. Short-run memories can go long-run memory through the procedure of consolidation, affecting dry run and meaningful association. Unlike short-run memory ( which relies largely on an acoustic, and to a lesser extent a ocular, codification for hive awaying information ) , long-run memory encodes information for storage semantically ( i.e. based on significance and association ) . However, there is besides some grounds that long-run memory does besides encode to some extent by sound. For illustration, when we can non quite retrieve a word but it is â€Å"on the tip of the tongue† , this is normally based on the sound of a word, non its significance. Long-run memory is frequently divided into two farther chief types: explicit ( or indicative mood ) memory and implicit ( or procedural ) memory. Declarative memory ( â€Å"knowing what† ) is memory of facts and events, and refers to those memories that can be consciously recalled ( or â€Å" declared † ) . It is sometimes called expressed memory, since it consists of information that is explicitly stored and retrieved, although it is more decently a subset of expressed memory. Declarative memory can be farther sub-divided into episodic memory and semantic memory. Procedural memory ( â€Å"knowing how† ) is the unconscious memory of accomplishments and how to make things, peculiarly the usage of objects or motions of the organic structure, such as binding a shoe lace, playing a guitar or siting a motorcycle. These memories are typically acquired through repeat and pattern, and are composed of automatic sensorimotor behavior that are so profoundly embedded that we are no longer cognizant of them. Once learned, these â€Å" organic structure memories † allow us to transport out ordinary motor actions more or less automatically. Procedural memory is sometimes referred to as inexplicit memory, because old experiences assistance in the public presentation of a undertaking without explicit and witting consciousness of these old experiences, although it is more decently a subset of inexplicit memory. 1|Page

Gender and Societal Norms Free Essay Example, 1500 words

Socialization and moral development are features that vary between the female and male gender, thus, they can influence the development of these individuals into criminals. In diverse societies, there is the teaching of young girls to emulate the good morals of their parents. This predisposes them to an ethic of care (Qureshi, 2014). Thus, this kind of ethic bars women from engaging in violent acts and other related behaviors that can harm others. Society teaches girls at the tender age to be afraid of separating or losing their loved ones. Such apprehensions deter females from involving in criminal activities. On the contrary, society teaches young men to be status-seeking, which compels them to have a varied view of the world in which autonomy is crucial. Socialization of young men emphasizes independence, separation, and autonomy as well as much goal-oriented and assertive than girls. Thus, this increases the chances of men behaving violently. Social control, gender norms and o ther related factors discourage and prevent women from any access to criminal opportunities. For instance, there is less chance of employing women in particular jobs that can offer opportunities for them to engage in criminal activities such as theft and drug dealing (Lemelle, 2013). We will write a custom essay sample on Gender and Societal Norms or any topic specifically for you Only $17.96 $11.86/pageorder now Examples of such jobs include carpentry and truck driving. It is noteworthy that certain jobs offer women the chance to engage in petty offenses. For instance, attempts to make a commission on sales can render a female employ into prison. A considerable disparity in crimes originates from the variation in the risk-taking styles and motivation of women and men. Women usually take profound risks to maintain treasured relationships, while men take risks based on competitive advantage or status (Dodge et al. , 2013). For instance, women may engage in crimes that involve embezzlement of funds on account that they want to protect their relationships or families financially. On the contrary, men can engage in crimes constituting embezzlement on grounds that they want to protect their financial and social status.
