The Human Perception of Loudness Essay Example for Free

The Human Perception of Loudness Essay Aim: The aim of the experiment was to discover the difference between loudness and sound pressure level, gain knowledge of typical sound level values in common environments and to be able to make rough estimations of what sound level measurements could be in different places. Method: The CEL-440 sound level meter was used to measure sound pressure levels in dbz and loudness levels in dBA. It was decided to base the experiment on learning environments around the university, ranging from areas of study inside and outside. This was done because, as the areas that are considered in the experiement are ones that the group would use in everyday life so it would be interesting to see what loudness and sound pressure levels most people live and sit in during there every day lives. Loudness is a psychological quality which relies on human interpretation. Loudness is hard to measure as it depends on how the human ear responds to it. Sound Pressure Level is linked to loudness as it is a physical quantity which can be measured. Sound Pressure Level can be measured, when loudness cannot. Sound pressure level ranges from the smallest detectable sound which is measured in pa (pascals). Sound is heard, by air follicles vibrating on the ear. The highest sound is atmospheric pressure around 1,000,000pa that can not physically be heard. If it was any louder then there would not be any atmospheric pressure left so everything would be destroyed. Threshold of human aural perception is the pressure of the air molecules colliding with the ear drum which is close to the threshold of perception. Young people with sensitive hearing are able to hear as little as 20pa, but most people will not be able to hear this measurement. The just noticeable difference depends on factors such as overall levels and frequencies. However, it is conveniently remembered as 1dB, one decibel. When something is measured in decibels it is refering to ratio (10log power difference, 20 log voltage difference) between the amount of two levels and the level being measured. How do people hear sound? When a sound is made, it is dependant on the response of the human ear and every ear responds in a different manner. Everybody has a different individual shape to their ear. The ear canals are unique to every individual, and ear canals resonances occur at approximately 3.4khz and 13khz, but this depends on age and health. There is no accurate way of measuring sound as everybody interprets is differently. The diagram below shows the basic structure of the ear and where the ear canal is situated. Fletcher and Munson Experience 1993 was the breakthrough of an investigation that explains a great deal. They investigated the perception of loudness in human subjects. The loudness level estimated by the subject for different stimulus levels and different frequencies was recorded. Humans have a limited range of hearing whereas dogs can hear things much louder. Fletcher and Munson discovered a graph of equal loudness contours. Shown below. When the ear hears sound it is not equally sensitive to all frequencies, especially the low and high frequency ranges. Fletcher and Munson charted the response to frequencies over the entire audio range and this is shown in the graph above. The set of curves show the sound pressure level of pure tones that are percieved as being equally loud. The graph has been plotted for each 10 decibel rise in level when the reference tone is 1kHz. This is also referred to as loudness level contours. From 1 to 5kHz the curves are lowest in the range. There is a slight dip at 4kHz which probably indicates that the ear is most sensitive to frequencies in this particular range. The levels of intensity for higher and lower tones had to be raised in order to create the equal impression of loudness. The results were accurate to the predictions made for the different locations. The sound pressure level in the places such as the computer labs and lecture theatres were thought to be quieter. However there were many computers and equipment which were left on standby, appearing off and very quiet. It was thought that the the library upstairs should have been quieter than downstairs as it is where books are kept and downstairs is where groups congrigate. Although it seems fairly quiet in the upstairs section, the air conditioning fitted can effect the sound pressure level recorded. The recording booths and live room were exactly as predicted which is very good as it means they have been built correctly and are one hundred percent sound proof. The relationship between the dBa results that were collected and the dBz were more or less as expected. The measurements that stood out were the library upstairs as the sound pressure level was much higher than the loudness along with the Lecture room. The lecture room was empty until it was entered by the group and there were no lights on either. The lights turned on automatically when people entered. It was thought that in both the library and the lecture theatre there are a lot of frequencies that exist but cannot physically be heard. This would include certain machinary such as air conditioning, automated light response system, fans from computers that seem very quiet, anything that is left on standby which appears off. Loudness is a subjective quality in which is depends a huge amount on sound pressure level as well as the frequency spectrum and amplitude envelope of sound. It also depends on the environmental conditions under which it is heard and the auditory of the listener.

Feminism and its impact on society

Feminism and its impact on society Feminism is one of the basic movements for human liberty (Schneir, 1996: xi) a feminist role in society is to actively recognize the need for, and work towards creating equality for all women. Feminism is purely a movement which intends to enlighten people with a goal of improving gender equality and strengthening womens status in society. Geographers began to study feminism in the late 1970s as a resistance against sexism. Since the late 1970s to 90s, the work of many feminist geographers have explored the connections between gender and geography, and has challenged gender inequalities in both geographical discourse and knowledge about the world (Blunt, A Wills J 2000. Pg 91). Feminist geography is a more advanced approach within human geography, it addresses the various ways in which genders and geographies are mutually constituted (Pratt, 1994: 94). Feminist geography questions the patriarchal and hierarchical assumptions on which geography is based, and highlights the oppression and difficulty women face through gender inequality. The Feminist theory is concerned with analysing and explaining as well as changing gendered power relations. Our society is characterized by differences in power and status of two groups: men and women. Men inevitably have more power and status than women; this results in their interests being reinforced by patriarchy. We live in a patriarchal society that accepts as essentially unproblematic the routine beating, raping, and murder of women. (Batzell, R 2009) Feminist theories has inspired critical work across the humanities, social sciences and natural sciences that seeks to disrupt the gender imbalance of power that exists both within and beyond the academy (Alison, Blunt 2000). Feminists also claim that many cultural beliefs in contemporary society benefit men and ultimately disadvantage women. Therefore their fundamental aim is to reverse this disadvantaged role women play in society. Feminism spans all ideologies, activities, and policies whose goal it is to remove discrimination against women and to break down the male domination of society (Lovenduski and Randall, 1993: 2) Associations between gender and geography as a discipline will be further explored, illustrating how production of geographical knowledge has been gendered. Gender represents differences between womens and mens attitudes, behaviour and opportunities that depend upon socially constructed views of femininity and masculinity. The term gender is preferred to that of sex, which is restricted to the anatomical distinction between the sexes rather than social differences. (McDowell, 1986: 170) Gender is a social relation that positions men and women differently in society. Feminists may argue that there is a hierarchy of power held directly by men who are in a more advantageous position in society, because of their gender. Gender is a part of an individuals identity; it influences what we think about ourselves, people and also our relationship with other people (Blunt, A Wills, J 2000 Pg 92). To be born male or female does not imply masculinity and femininity; rather ideologies about masculinity and femininity are socially constructed. This is further supported by (de Beauvoir, 1949) One is not born but rather becomes a woman. These social constructions are very crucial in shaping the everyday lives of men and women. Socialist feminist geographers (also known as Marxist feminists) look at the way in which the structuring of space creates and continues to maintain traditional gender roles and relationships in society and how spatial variations in gender impact where an industry locates. Employers locate to areas where there is an availability of cheap female labour, and the quantity of this type of labour. However this can vary over regions and nations. Their message also emphasizes that true equality cannot be achieved and will be difficult to attain without a major revolution, in particular an economic one, as power and capital are distributed unevenly in the capitalist society we have today. Women are often stereotyped as domestic workers, consumers and care workers and these ideas are mostly associated with femininity. This type of employment is often seen to be less worthy and deserving of a high pay and less respected than traditional masculine roles. There seems to be a tendency to value and remunerate women less for their work as they enter a profession. It is not fair for women to individually work so that they can rise to powerful positions in society. It is acceptable to say that power needs to be redistributed throughout society. In contrast, ideas about full-time employment and citizenship beyond the home are often shaped by ideas of masculinity; this is reflected by the notion of men to be suitable to certain spheres of work and participation in public life rather than women. (Massey 1996, cited in Blunt Wills 1993). Gender inequality can be witnessed everywhere through the masculine spaces of mines and city workers, down to the feminized spaces of garment factories and primary teaching. However these gender roles and relations are ever changing, and to reiterate they are socially constructed as well as dynamic rather than permanent and static from birth. Inequality also lays heavily in the difference in pay between men and women. As a recent study found that simply being a woman was the most serious impediment to women in the workplace (reportageonline.com), women working full-time earn on average 16.4% less per hour than men working full-time. Other figures show women working part-time earn on average 35.3% less per hour than men working full-time (based on mean hourly pay in 2009; data from EHRC, 2010). The difference in earnings is created through the gender segregation of occupations and women being discriminated against. Furthermore the lower paid work is usually carried out by the females as there is a gender stereotype for women to take responsibility of certain jobs. There is also an under-representation of women in vocational work and in large firms. Nevertheless, Gender has come a long way, and in recent years has dynamically changed as now more women are paid fairly in employment Feminism on a whole has had a positive impact on society it has been a dramatically successful social movement. It has changed womens expectations and perspectives on their lives. In the past, women would have to marry to gain financial security and stability. Women are now working and more independent than ever, by earning their own living, they do not need to rely on a man for stability. Sue Sharpe (1976, 1994) has conducted research into this area and in the first edition of her book Just Like A Girl (1976) she interviewed girls and asked them about their future plans, which were to get married and have children. A career was not seen as important neither a high priority. She later repeated her research in the 1990s and found that the girls priorities had changed; their careers came first and marriage and children were not as important anymore. Women now have far more choice, variety and opportunities compared to the past. Feminism has also transformed what men expect from sharing their lives with women and how they will behave towards women. Children growing up now simply take for granted feminisms messages about sexual equality and justice when only 30 years ago such messages were widely opposed as extremist and threatening to the social order. No other movement has so rapidly revolutionized such deeply held patterns of behaviour (Coward, 1999: 194) Finally, in response to wider social shifts, the aspirations of girls may have also increased. Thus girls now may have their sights set on university and a career and this may translate into increased engagement with school. Recent reforms have opened opportunities to women most notably the Sex Discrimination Act 1975, which made gender discrimination in employment illegal. women still suffer many injustices, discriminations and sometimes even outrages but there is no longer a coherent picture of male advantage and female disadvantage à ¢Ã¢â€š ¬Ã‚ ¦ Gender remains a crucial division in society but in a much more fractured and inconsistent way (Coward, 1999: 192-3) The key message of feminism in the 21st century society should highlight choice in bringing a personal meaning to feminism is to recognise others right to do the exact same thing. Women all over the world nationally, regionally and globally should be able to embrace this powerful message of feminism and be able to create a positive meaning of their own womanhood and femininity. However, despite feminism being a strong successful movement, inequality and exploitation of women still exist and sadly there are women today, who are trapped in a society which doesnt value them and leaves them neither choice nor freedom to express their views and rights.

Maintaining the Audiences Interest in Talking Heads :: Talking Heads Alan Bennet Essays

Maintaining the Audience's Interest in Talking Heads One character talking to a camera for half an hour, Do you call that drama? How does Alan Bennet try to maintain the audience’s interest in his Talking Heads? In A Lady of Letters, Patricia Routledge plays the part of Irene Ruddock, who is a very lonely woman that has an obsession with writing letters to everyone to complain about the smallest of things. She lives by herself, and has done since her mother died. A Lady of Letters is a drama because it includes different amounts of lighting at certain points of the video. Routledge also acts when she is speaking to the camera, for example she gets very upset at some points e.g. when she talks about when the police told her the little boy over the road had died of leukaemia. She also expresses herself well by her actions. At first Irene seems like a very highly classed woman, very respectable and knows what is wrong and right. She also appears to be a very respectable lady. We know this because in the video, it shows her having her tea and biscuits with a napkin. However, throughout the video, we see some changes to Irene; we see that she might not be as respectable as we first thought. One of these reasons is because when she goes to the doctors, she says â€Å"I said I was getting upset, like I did before†¦Ã¢â‚¬  This indicates that she may have been ill because of certain happenings which were probably to do with the letters which she writes. Shortly after this, she lets us know about when the vicar came around, talking to her about god. She then tells us about how she is an Atheist. We do not expect this because you would have thought someone as respectable as Irene would believe in God and go to church every Sunday morning. â€Å"They don’t expect you to be an atheist when you’re a miss†¦Ã¢â‚¬  This shows that because she told the Vicar that she was an atheist, he did not know what to say, because he like us expected her to believe in God and go to church like every other respectable lady like her. Next we hear about her visit from the Police, which is where we find out what she really is like. At first, the male police man talks about the different types of letters which she had wrote in the past, and then we find out that she has been told to keep the peace by the courts. At this point, we finally realise that she isn’t that

There is one Haitian proverb that has never lost its potency, despite the atmosphere of economic adversity, numerous civil wars, and political unrest:  ¡Ã‚ °Piti, piti, wazo fe nich li. ¡Ã‚ ± Literally, the phrase means,  ¡Ã‚ °Little by little, the bird builds its nest ¡Ã‚ ±; figuratively, it represents building one ¡Ã‚ ¯s way,  ¡Ã‚ °little by little,  ¡Ã‚ ± toward one ¡Ã‚ ¯s goals in life. To further understand the saying ¡Ã‚ ¯s significance, we should first consider the nature of birds. From tailorbirds that suture leaves together to some hummingbirds and pee wee wrens that use lichen and spider webs to build their nests, we can see the resourcefulness birds demonstrate in obtaining nest-building materials. My life has been a similar process of building a metaphorical nest -- acquiring such qualities as compassion, dedication, and leadership through a variety of experiences to prepare for a successful career as a physician. As a bird builds through changing seasons, I too have prepared for the study of medicine through variously themed  ¡Ã‚ °seasons ¡Ã‚ ± in my life. During high school, for example, I focused my activities on serving the various communities of which I am a part. After joining Mt. Olivet SDA Church, I became involved with the community of Williamsville, New York -- participating in an anti-drug rally and health fair, leading local public speaking events, singing in church choirs at nursing homes, and visiting hospitalized church members. I was also a mentor and counselor for underprivileged children...

A Mexican Farmer Worker in USA Essay -- Immigration Immigrant Essays P

A Mexican Farmer Worker in USA The first immigrant I interviewed will be referred to as â€Å"Jess†. Jess is from Guanajuato which is in southern Mexico. Jess, his five brothers and sisters, and his parents were farmers. They grew corn as their main crop. Jess’s family lived in a three-bedroom brick house in Mexico. Their house surprisingly had water and electricity. He only made 100 pesos a day ($10.00 U.S.). According to Jess, this was not enough money to get by on his own. He said that the average person in Mexico needs at least 150 pesos per day to live on their own and someone raising a family needs much more than this. This is why in 1985, at the age of 18, he came to Arizona to find a better job and to help his family. Jess paid the coyotes $150.00 to get him across the border, walking through the desert for 12 hours and riding in the back of a truck for the rest of the way. The coyotes that helped him were a very nice family and they were not threatening at all. He says that cro ssing the dessert was a scary experience and that he feared they would be burglarized, but claims that he made it across without running into trouble. It only took Jess two days after arriving in Phoenix to find a landscaping job. According to the statistics in Transnational Villagers, between 1996 and 1999, 60.3% of Non-Dominican Hispanics, like Jess, were employed in the U.S. and 45.3% of them worked full time. Jess did not require the help of job agencies to find work. Of course, he was undocumented at the time but this was not a problem in the landscaping business. With the money from this job, he was able to buy his first car which he paid $300 for. Landscaping paid $4.00 per hour which was minimum wage back then. He remain... ...ct each other. Its first objective was to reduce the number of undocumented immigrants. The second objective was to provide undocumented immigrants already working in the U.S. with a chance to become legal and obtain rights. The Act established employer sanctions against businesses that knowingly employed undocumented immigrants. It also provided those immigrants who had been living illegally in the U.S. since 1982 with a chance to obtain temporary resident status. The United States is slowly realizing how important these immigrants are to the U.S. economy. There service to the United States deserves the respect and gratitude of every U.S. citizen.

Perfume Suskind

Interactive Oral: Debate Title: How was your understanding of cultural and contextual considerations of the work developed through the interactive oral? The setting of Perfume was crafted accordingly to author’s intention so that the main character would develop specific characterizations that will later on, lead him to make a decision whether to live or to die.Suskind does this by placing Grenouille, who has a keen sense of smell in the 18th century France and distinctively allowed the plot to develop and establish in a setting of a malodorous and a scent-conscious society, where people were obsessed with pleasurable scent and uses it distinguish themselves within the hierarchy. In addition, Suskind hinted that smell is depicted more than merely the ingredients of a perfume but could also be a resemblance as the scent of a person’s soul, thus he made a correlation between the existences of with the existence of a person’s soul.Hence in Perfume, scent has become the crucial factor in determining the human soul, the identity of oneself. Suskind also made a point where your own smell will give away your identity like the poor would have malodorous smell but ironically, he decided to leave the main character scentless. Grenouille was isolated simply because in the eyes of the society, he does not have the substance (body odour) that established his identity as a human being. Moreover, Grenouille also decided to detach himself away from the society because he does not have the need to establish relationships.Through isolation and detachment, Suskind have effectively molded the main character’s psychological state of mind by limiting Grenouille’s knowledge and only allowed him to gain knowledge through smell and scent rather than language itself so that Grenouille only understood that things that smells, exist. During an epiphany and Grenouille’s encounter with the â€Å"fog†, he discovered and learnt the truth that h e does not bear a smell or scent (based on his knowledge and understanding) and he belonged nowhere within the hierarchy, he felt his own personal identity is hindered almost as though he does not fully exist.The cumulated awareness has aided him to realize upon the ultimate truth that he was indeed born scentless and can never own a scent. Upon discovering and understanding the final truth, he decided that his existing life has bared no significance to himself, hence leading to his choice to die. Perfume was written in such a way that it indirectly criticizes the human’s nature – the endless greed through Grenouille, where he chooses to pursue after something that is beyond his competence. (408) Grenouille reached an epiphany when he encountered the â€Å"fog† in his dreams.The fog indirectly symbolizes as the ultimate truth which he has not explored and fully implicit. Grenouille only understood that he could not smell the fog hence the fog implies as a non-ex istent thing. This is how he had a realization that he is nonexistent. Again Suskind successfully correlate scent as identity. The moment he realized that the fog is a part of him, he had internal conflicts where he understood that he does not have an identity based on his understanding. He realized that he belonged nowhere in the hierarchy – hence only understood that his personal identity is hindered because he does not have smell of his own.When Grenouille realized that he was scentless and found himself to be nowhere within the category, he felt his own personal identity is hindered almost as though he does not fully exist. Hence such understanding has led him to an internal conflict where he realized that he was born scentless and his created scent could never be his thus leading to his choice to die. The setting was crafted in such way that it affects the main character’s psychological state of mind and its characterizations towards the choices. (332)

Climate and Polar Maritime Air Essay

To what extent is the climate of the British Isles a product of the air masses that affect it? Climate is defined as the weather averaged over a 30 year period, with weather being determined by temperature, humidity, wind and precipitation. The climate in the British Isles is described as cool temperate western maritime climate, although there are regional differences in climate across the British Isles; with average temperatures ranging from -0.2 to 20.9 degrees Celsius. The climate of the British Isles is influenced by the movement of five major air masses. However, it is also influenced by other factors, including its topography, ocean currents, latitude, and weather systems. Firstly, it can be argued that air masses play a large part in the overall climate of the British Isles. Air masses are large bodies of air with reasonably uniform temperature, pressure and humidity throughout. There are five main air masses that influence the climate: tropical maritime(TM), polar maritime (PM), tropical continental (TC), polar continental (PC) and arctic maritime (AM). The direction o f the air masses can be seen in the diagram below. Tropical Maritime brings warm moist air from the Atlantic Ocean. This warm air hits areas of high relief in western England and Wales, causing the air to rise, which means clouds form. Areas of high relief in the west of England include Dartmoor and Exmoor. The air is very moist as it is from the ocean, so there is lots of precipitation. This wind is warm, which means that is has a warming affect in the winter, however in the Summer because the land has a lower specific heat capacity, it heats up more than the Atlantic ocean. Therefore it has a cooling affect in summer. Tropical Continental air masses bring hot and dry air in summer. This causes high temperatures with very little precipitation, and is the reason for heat waves in the British Isles. For example the heat wave in July 2013, where temperatures reached 33.5 °C . Polar Maritime air masses bring cold moist winds as they originate from a north westerly direction, over the Atlantic Ocean. This therefore causes very cold wet weather in the British Isles, especially in the westerly parts of the British Isles where there is high relief causing precipitation. Polar Maritime air is dominant over the winter season. Polar Continental air masses originate from high latitudes such as Siberia so therefore bring very cold conditions with them, however as they come from land not ocean, the air masses bring dry conditions. Arctic air  masses originate over the Arctic Ocean where high pressure dominates. The air masses bring extremely cold temperatures, however is only dominant in winter, and sometimes in spring. However this air mass is more likely to affect the climate in Scotland, and northern England, as it has come from a northernly direction. Overall this shows that air masses do play a significant role in the overall climate of the British Isles, however some air masses are more dominant than others in different seasons, and some air masses are dominant in different areas of the British Isles. The climate of the British Isles is also greatly affected by weather systems such as depressions. Mid Latitude depressions are formed over the Atlantic Ocean on the Polar front. They move in an easterly direction across the British Isles. The depressions are low pressure systems that are formed when moist, warm â„ ¢ air meets drier, colder PM air. The warm, moist air is forced upwards, by the colder denser air. The Coriolis effect causes the air to rotate in an anticlockwise direction. The jet stream is also involved as it moves the depression from west to east. The climate associated with depressions is strong winds, clouds and precipitation. However the climate is dependent on which air mass is over the British Isles. Polar maritime air brings average temperatures for the season in winter, around 5 °C-8 °C in January, but cooler temperatures for the summer season, at around 16 °C to 18 °C in July. This air mass also brings lots of precipitation. Tropical maritime air brings humid and mild weather in winter, with temperatures averaging at around 12 °C-14 °C in January. Tropical maritime can also bring thunderstorms , due to the humidity and low pressure. An example of when a depression has greatly affected the British Isles was the Great Storm in 1987. This fast moving depression caused wind speeds of up to 81mph. The British Isles experienced lots of rainfall, and there was even an increase in temperature by 6 °C in places, where the warm front was situated. This shows how depressions can have great impacts on the climate of the British Isles, however this large depression is not common, so does not usually affect the climate. Overall, depressions have a great impact on the climate of the British Isles both in winter and summer, however it can be argued that air masses play an important role in the formation of depressions, so this also shows that air masses indirectly affect the climate. The British  Isles has a latitude between 50 °N and 60 °N. This has a great impact on the climate that it experiences, meaning that the latitude is another factor that will influence the climate of the British Isles. The latitude of an area will affect how much insolation it will receive. This is due to the angle of incidence, which can be see in the diagram below. A larger angle of incidence will mean that the insolation from the sun will only disperse over a small area, whereas a small angle of incidence means the same amount of insolation will be spread over a larger area. At a 30 ° angle, a one wile wide ray of insolation will be dispersed over a two mile radius, whereas an angle of incidence of 90 ° with the same ray of insolation will be dispersed over a one mile radius. Higher latitude have smaller angles of incidence, meaning that they will receive less insolation. Therefore the latitude of the British Isles means that there will be temperate conditions. It is not likely that the British Isles will experience a very hot climate due to the fact that id does not receive enough insolation to heat up the surrounding air and ground. This can be seen if you compare the average yearly temperatures of the British Isles compared to Somalia, which is found at a lower latitude of 2.03 °. The British Isles has an average temperatures ranging from 8.5-11 °C. In contrast Somalia has temperatures around 24-31 °C. This demonstrates how that latitude of an area can greatly impact the temperature, which means it affects the overall climate of the area. This shows that latitude is a factor other than air masses that will impact the climate of the British Isles. Altitude is another factor that influences the climate of the British Isles. On average the air temperature falls by 0.65 °C every 100m rise in altitude. This is due to the fall in pressure as the altitude increases, meaning molecules have less kinetic energy. For example Ben Nevis has a height f 1,344 metres, and has an average annual temperatures of -5 °C, compared to the British Isles which has an average annual temperature of around 8.5-11 °C. This shows that altitude has a direct impact on the temperature of the British Isles, so areas of high altitude in the west of the British Isles, such as Cambrian will have lower temperatures. The altitude of the British Isles will also cause precipitation, as when moist air masses move across areas of high relief, the air masses are forced upwards, where the  cool condense and form clouds. For example in Wales the Cambrian mountains receive over 100mm rainfall per month all year round. This is due to the tropical maritime and polar maritime winds bringing moist air. Overall this shows that altitude can have a large impact on the climate of the British Isles, however air masses are also involved in this, which demonstrates that air masses still play a significant role in the overall climate. Lastly, ocean currents are another factor that have a large impact on the climate of the British Isles. The most significant ocean current is the Gulf Stream, which . Gulf Streams are influenced In conclusion, the climate of the British Isles is a product of air masses so a large extent. Although there are many other factors that also affect the climate, air masses are also involved in these factors, such as the formation of depressions, or the movement of ocean currents. Therefore air masses so also indirectly influence the climate of the British Isles, meaning that they play the most significant role in affecting the climate.
