Disproving the Theories of Evolution

Disproving the Theories of Evolution Abstract Natural selection is one of the numerous theories that attempt to explain the evolution of living things from their primitive origins to the more advanced organisms existing today. At its core, this theory supports the notion that only the strongest organisms survive in a changing environment while their weak counterparts die off. Nevertheless, various circles regard the evolutionary theory by natural selection as practically impossible. Since its conception, proponents of the theory have defended it with the help of serious misinformation and propaganda. However, the theory of evolution has been discredited entirely as being scientifically invalid by such fields as paleontology, genetics, biochemistry, and microbiology. Numerous findings continue to reveal that evolution never happened, is devoid of tangible scientific evidence, and is incompatible with the truth. One such area is the creationist perspective of the origin of life and the universe. Creationism provides the indication that the universe is the work of an Omniscient Creator. Scientific communitys Opposition Evolution has been and continues to be not only one of the most widely debated issue but also one of the most controversial. Some quarters have a serious problem with calling the Darwinist evolution a theory for the reason that it lacks testable explanations for observable occurrences (Isaak). The Darwinian theory of evolution postulates the idea that the planetary species arose through descent with progression and modification from a single common ancestor by the process of natural selection. While this presumption may contain some element of truth, it has not received complete acceptance across the entire spectrum of the society since evolutionary ideas first came to prominence in the early parts of the 19th century (Luskin). The first opposition to its tenets comes mainly from the scientific community, which has not found any past or present scientific evidence to validate the claims of Darwin. Moreover, todays criticisms and denials also come from all quarters in various forms su ch as creationism, neo-creationism, and intelligent design. Even though several points exist on either side of the creationism versus evolution argument, notwithstanding the gaps on both sides of the divide, it becomes apparent that the theory of evolution has some serious fundamental flaws. Creationism is the belief that concept and design require a creator (Sarfati and Mathews). When applied to detecting design in the universe and life, this principle becomes a more reasonable explanation to believe in a higher power as the Creator or Designer of both (Sarfati and Mathews). Unlike the concept of evolution, which remains unproven and continues to lack even the slightest experimental or observational support, the creationist argument is sound because it argues against a set of misunderstandings about evolution that people are right to consider ludicrous (Fodor and Piattelli-Palmarini). For this reason, a large part of the society is likely to embrace creationism. Moreover, various religious denominations already propagate the belief in a higher power, making creationism more intellectually and socially palatable to a majority of people, both scholars and lay audiences. A related issue is the tendency of individuals to identify with things, beliefs, or concepts that exemplify the best of humanity or portray humans as special. In this regard, creationism hits the nail on the head as it conceives the advent of humankind as a deliberate, personal, well-thought out, and loving process. In contrast, evolution paints a grim picture of a random, impersonal, and d etached process that does not appeal to the moral and spiritual sensibilities of many people, hence its unpopularity. The first claim against natural selection, the central premise upon which the theory of evolution rests, is that it lacks the power to be responsible for all the variability seen in all the innumerable forms of life. A close inspection shows that neither natural selection nor mutation has any evolutionary force or gives the slightest support to the notion that living things can evolve and gradually turn into a new species (Yahya). Natural selection predicts the survival of organisms possessing the most appropriate characteristics for their natural habitats and the extinction of those that lack the advantages (Rennie). For instance, in a herd of deer threatened by wolves, those who run fastest survive and those who do not run swiftly are hunted down and eliminated resulting in a herd of swift-running deer. However, no matter how long the process lasts, the deer will a lways remain a deer and never another species. For that reason, natural selection cannot cause the development of a new species, much less new life forms (Yahya). Competition for survival The second criticism of evolution driven by the process of natural selection concerns the assertion that the living world is in a perpetual competition for survival, something Darwinism calls the survival of the fittest (Yahya). Several reliable observations continue to reveal that organisms, particularly those at more advanced levels such as humans and dolphins display solidarity and social behavior that can be defined as cooperation. Therefore, the survival of the fittest might not be any more superior or significant than the survival of the luckiest (Yahya). The weakness of evidence The third criticism against evolution is that several lines of evidence for Darwinian evolution and common ancestry are weak. Firstly, there is the failure of development of biology in explaining why vertebrate embryos start diverging from the very beginning of development. Secondly, DNA and molecular evidence paint conflicting pictures about the grand tree of life (Luskin). Lastly, available fossil records do not provide proof for the Darwinian evolution (Luskin). The evidence of small-scale changes commonly paraded by evolutionists such as the slight variations in the color of wings of peppered moths or the size of finch beaks are isolated cases of microevolution and are not evidential proof for macroevolution (Rennie). Conclusion Even though evolutionists portray the theory of evolution as a scientific fact, various findings for the several years separating Charles Darwin and the present day has utterly disapproved this theory. Darwinism is inconsistent with the truth, and its principles of natural selection and mutation have been shown to lack any evolutionary power to create new species. The more the details of nature and scientific studies have been revealed, the more extraordinary characteristics of life in its diversity have been discovered that can never be explained in terms of natural selection.

Kalkstein Department of Geography and Environmental Engineering, United States Military Academy, West Point, NY, USA records (1975–2004) were examined for 11 first- and second-order weather stations in and around Shanghai.Additionally, automatic weather observation data recorded in recent years as well as daily all-cause summer mortality counts in 11 urban, suburban, and exurban regions (1998â₠¬â€œ 2004) in Shanghai have been used. The results show that different sites (city center or surroundings) have experienced different degrees of warming as a result of increasing urbanization. In turn, this has resulted in a more extensive urban heat island effect, causing additional hot days and heat waves in urban regions compared to rural locales. An examination of summer mortality rates in and aroundShanghai yields heightened heat-related mortality in urban regions, and we conclude that the UHI is directly responsible, acting to worsen the adverse health effects from exposure to extreme thermal conditions. Keywords Global warming . Urban heat island . Heat wave . Human health Introduction In recent years, the impact of weather on human health has become an issue of increased significance, especially considering the potential impacts of global warming and an increased urban heat island effect due to urbanization (Kunst et al. 1993; Kalkstein and Greene 1997; Guest et al. 1999; Sm oyer et al. 2000).Warming of the climate system is unequivocal. The IPCC Fourth Assessment Report (AR4) clearly indicates that the updated 100-year linear trend (1906–2005) of global surface temperature is 0. 74 K. The warming trend over the last 50 years has averaged 0. 13 K per decade and 11 of the last 12 years (1995–2006) rank among the 12 warmest years since 1850 (IPCC 2007). A Int J Biometeorol (2010) 54:75–84 76 warming climate will likely result in an increase in the frequency and intensity of heat waves (McMichael et al. 1996; Meehl et al. 2001; Patz and Khaliq 2002). The urban heat island (UHI) has become one of the largest roblems associated with the urbanization and industrialization of human civilization, as the increased temperatures associated with the UHI tend to exacerbate the threats to human health posed by thermal stress. As a result, the UHI has been a central theme among climatologists, and it is well documented in many metropolitan areas a round the world (Oke 1973; Katsoulis and Theoharatos 1985; Balling and Cerveny 1987; Lee 1992; Saitoh et al. 1996; Yamashita 1996; Bohm 1998; Figuerola and Mazzeo 1998; Klysik and Fortuniak 1999; Kim and Baik 2002; Wilby 2003). The UHI experienced by many cities is larger at night than uring the day, more pronounced in winter than in summer, and is most apparent when winds are weak. For example, in Beijing, the difference in mean air temperature between the city center and surrounding fields can be as much as 4. 6 K (Zhang et al. 2002; Song and Zhang 2003). This results in additional hot days in urban locales, which can directly influence the health and welfare of city residents. As UHIs are characterized by increased temperature, they can potentially increase the magnitude and duration of heat waves within cities. Scientists have also discovered that the impacts of heat waves on humans vary among ifferent regions within a city. As early as 1972, Buechley et al. (1972) investigated the relationship between the heat island and â€Å"death island† and found that the mortality rate during a heat wave increases exponentially with the maximum temperature, an effect that is enhanced by the UHI. Clarke (1972) revealed that the nighttime effect of UHIs can be particularly harmful during a heat wave, as it deprives urban residents of the cool relief found in rural areas during the night. Thus, during heat waves, death rates are often much higher in cities than in outlying environs (Henschel et al. 1969; Buechley et al. 972; Clarke 1972; Jones et al. 1982; Smoyer 1998). An epidemiologic study of mortality during the summer 2003 heat wave in Italy also illustrated that those living in urban regions have an elevated risk of death compared to those living in suburban or rural areas as a result of heightened urban temperatures (Conti et al. 2005). Unlike purely tropical regions that remain warm all year round, Shanghai experiences a subtropical climate with cold, dry winters and wet, hot summers, as well as a pronounced UHI (Ding et al. 2002; Zhou et al. 2002). Shanghai has been found to be prone to heat-related ortality (Tan et al. 2004, 2007), although few studies have quantitatively or qualitatively examined the impact of the UHI on the frequency or the intensity of heat waves along with its corresponding impact on heat-related mortality among the urban and suburban populations. Thus, the goal of this paper is to determine the influence of the Shanghai UHI on heat waves and human health within both urban and rural locales. Materials and methods The study was carried out over the region of Shanghai, China, which encompasses approximately 6,300 km2, and contains a population listed as slightly over 18 million in 006. In order to capture the effects of urban areas on local climate, 30 years (1975–2004) of daily maximum temperature were compiled covering only the summer months, defined here as May through October. These data were examined for 11 first- and second-order weather stations (Fig. 1) and were obtained from the Shanghai Meteorological Bureau. The specific sites in this study are: the urban site (XuHui-58367), suburban sites (MingHang-58361, BaoShan58362, PuDong-58470, JiaDing-58365), and exurban sites (ChongMing-58366, NanHui-58369, JinShan-58460, QinPu58461, SongJiang-58462, FengXian-58463).For each year throughout the 30-year research period, we first examined the yearly extreme maximum temperature (the single hottest day in each year), the mean daily maximum temperature in midsummer (defined as July through August), and the number of hot days (defined as days exceeding 35 °C in Tmax) for each of the 11 stations. Simple linear regression was used to discern overall trends in the data, and the statistical significance of these trends was assessed (Table 1). The number of hot days, as well as heat wave duration at urban, suburban, and exurban sites, are listed in Table 2.The UHI intensity is typically de fined as the temperature difference (? T) between the urban (u), suburban (s), and exurban (e) locations. This is described in terms of the difference in daily maximum temperature between the urban center and suburban sites (? Tu-s), and that between urban center and the exurban stations (? Tu-e). The observed values of urban, suburban, and exurban sites were represented by the temperature from the urban site (XuHui station), the average of four suburban stations (MinHang, BaoShan, PuDong, JiaDing), and the average temperature from the exurban stations (ChongMing,NanHui, JinShan, QingPu, SongJiang and FengXian), respectively. The UHI intensity of each site (? Ti) is calculated by the temperature difference between the urban site (XuHui station) and each suburban or exurban site as follows: $Ti ? Tmax0 A Tmaxi While Tmax0 is the daily maximum temperature at the urban site, Tmaxi is the daily maximum temperature at the suburban or exurban site. In order to investigate the diurnal Int J Biometeorol (2010) 54:75–84 77 Fig. 1 Shanghai within China and the spatial distribution of 11 weather stations across Shanghai variation of the UHI intensity, the temperature difference etween the urban (XuHui), suburban (JiaDing), and exurban (ChongMing, FengXian, JinShan, SongJiang) sites are calculated from automatic weather stations from June through August, 2005–2007. The observed variations in the urban heat island effect have been plotted in Figs. 2, 3, and 4. Here, a â€Å"hot day† is defined as a day with a daily maximum temperature exceeding 35 °C in at least 1 of the 11 sites in Shanghai. Days below this threshold were categorized as â€Å"non-heat days. † Additionally, a heat wave is defined as a period with at least three consecutive hot days. Although this definition is somewhat arbitrary, it was hosen to correspond with the Chinese Meteorological Administration heat warnings, which are issued when maximum temperatures are forecast to e xceed 35 °C. Furthermore, with the assumption that each meteorological Table 1 The rates of increase and linear regression results by year for annual extreme maximum temperature, mean maximum temperature in mid-summer (Jul–Aug), and hot days at urban, suburban, and exurban sites Sites Yearly extreme maximum temperature Mean maximum temperature in mid-summer (Jul–Aug) Hot days Rate of increase (K / year) Urban Suburban Exurban XuHui MinHang BaoShan PuDong JiaDing QingPuChongMing NanHui JinShan SongJiang FengXian R2 p Rate of increase (K / year) R2 p Rate of increase (days / year) R2 p 0. 085 0. 049 0. 066 0. 067 0. 062 0. 051 0. 035 0. 029 0. 013 0. 034 0. 009 0. 389 0. 172 0. 271 0. 204 0. 241 0. 158 0. 090 0. 053 0. 013 0. 076 0. 004 0. 0001 0. 0181 0. 0022 0. 0095 0. 0043 0. 0244 0. 0918 0. 2053 0. 5409 0. 1276 0. 7196 0. 073 0. 051 0. 054 0. 054 0. 049 0. 045 0. 038 0. 028 0. 024 0. 034 0. 020 0. 240 0. 150 0. 136 0. 158 0. 128 0. 112 0. 082 0. 064 0. 042 0. 070 0 . 030 0. 0044 0. 0282 0. 0376 0. 0240 0. 0448 0. 0609 0. 1138 0. 1623 0. 2603 0. 1442 0. 3408 0. 64 0. 29 0. 40 . 34 0. 41 0. 28 0. 10 0. 09 0. 07 0. 20 0. 08 0. 388 0. 168 0. 278 0. 279 0. 272 0. 161 0. 070 0. 074 0. 026 0. 090 0. 036 0. 0001 0. 0197 0. 0019 0. 0018 0. 0021 0. 0229 0. 1427 0. 1305 0. 3817 0. 0952 0. 2950 Statistically significant slopes at 95% confidence level (p ? 0. 05) are in bold Int J Biometeorol (2010) 54:75–84 78 Table 2 The average number of hot days and the occurrence of different heat wave durations at urban, suburban, and exurban sites in Shanghai (1975–2004) Sites Hot days (days / year) Heat wave duration ?3 days XuHui MinHang BaoShan PuDong JiaDing QingPu ChongMing NanHui JinShan SongJiangFengXian Exurban observation site represents its entire area or district, we classify days in which more than eight of the sites experienced maximum temperatures above 35 °C as â€Å"largescale hot days†, thus covering 59. 6–82. 6% of the total area of Shanghai. The consistency of hot day occurrence among the 11 sites has been plotted in Fig. 5. All deaths recorded between 1998 and 2004 for all regions of Shanghai were obtained from the Shanghai Municipal Center for Disease Control and Prevention. These data consist of the daily mortality totals of each district for all causes of death and cover the summer study period.Excess deaths are calculated by subtracting a baseline death rate from the observed daily mortality value. Numerous methods have been identified in the literature for calculating the baseline mortality (Gosling et al. 2009), and here, we adopt a 30-day moving average for the same year (Rooney et al. 1998; Dessai 2002, 2003; Gosling et al. 2007). >10 days 18 12 11 8 9 9 5 2 6 8 2 9 4 8 1 5 4 2 1 3 4 2 5 1 1 0 1 0 0 0 0 0 0 Results Warming trends at the urban, suburban and exurban sites As demonstrated in Table 1, there are different linear arming trends in the different areas (city center, suburban, an d exurban areas) of Shanghai over the last 30 years (1975–2004), covering the yearly extreme maximum temperature, the average maximum temperature from July through August, and the number of hot days during the 2 Tu-s 1. 5 1 0. 5 0 May Tu-s ?7 days 39 25 22 18 27 26 9 7 14 21 8 11. 2 7. 4 7. 5 5. 2 7. 6 7. 7 3. 1 2. 7 5. 2 6. 4 3. 7 Heat Island Intensity ( K ) Urban Suburban ?5 days Tu-e June July 1. 4 Tu-e 1. 2 1 0. 8 0. 6 0. 4 y = -0. 001x 2 + 0. 0523x + 0. 1132 R2 = 0. 6951 0. 2 0 1975 October 2. 00 y = 2E-05x 2 + 0. 0411x + 0. 147 R2 = 0. 7704 1979 1983 987 1991 Year 1995 1999 2003 Fig. 2 The variation of urban heat island intensity [in terms of the difference of daily maximum temperature between the urban center and suburban sites (?

Tu-s), and that between the urban center and the exurban sites (? Tu-e) Fig. 2). From the 1970s to the mid-1980s, the UHI was much less pronounced, with an average difference in daily maximum summer temperature o f 0. 2–0. 4 K between the city center and its surroundings. However, these temperature differences increased during the period of study, particularly between the city center and the exurban locations. In fact, beginning in the mid-1980s, there is a distinct deviation between the UHI intensities of the exurban and the suburban sites. While the temperature difference of urban-exurban areas rose further to 1. 6 K, differences between the urban and suburban sites remained at approximately 0. K. This disparity is likely due to the rapid expansion of Shanghai into the suburban regions beginning in the mid-1980s. The UHI intensity was strongest in July during the summer months, where the average UHI intensity reached 0. 9 K between urban and exurban areas (? Tu-e), and 0. 6 K between urban and suburban areas (? Tu-s) (Fig. 3). Furthermore, the diurnal variation of the heat island intensity derived from the six automatic weather stations located in the urban (XuHui), suburban (JiaDin g), and exurban sites (ChongMing, FengXian, JinShan, SongJiang) in summer (June through August), 2005–2007, shows that he heat island intensity is more pronounced in the daytime than that in the night (Fig. 4). The highest value in the region of 0. 5–2. 0 K occurs at noon or in the afternoon, corresponding approximately to the time in which the daily maximum temperature is reached. The urban heat island and heat waves As a result of increased temperatures within the urban locales, the UHI may affect the number of hot days as well as the duration of heat waves, potentially increasing the risk of mortality from heat stress. The yearly average number of hot days and the total number of heat waves with different urations over the research period (1975–2004) at different locations in Shanghai are listed in Table 2. Not surprisingly, the largest average value of annual hot days is 11. 2 days per year in the urban site (XuHui), while fewer hot days occur in the exurban sites such as ChongMing, NanHui, or FengXian. Similarly, heat wave duration is also impacted by the UHI, so that the longest duration heat waves (for example, a heat wave with at least 10 consecutive hot days) usually occurred in the urban area. There were five such events at the urban location (XuHui) with only one event recorded t the suburban stations (MinXing, BaoShan, JiaDing). In order to discern whether increasing numbers of hot days are attributable to a regional climate warming or to an expanding UHI, we examined the five hottest years (1978, 1983, 1988, 1998, and 2003) and analyzed the consistency of hot day occurrence among the 11 sites. This was done to 80 determine the frequency of â€Å"large-scale hot days† in the investigation area during these years. Figure 5 illustrates a decreasing trend of the proportion of the large-scale hot days corresponding with an increasing number of hot days. For example, at least 1 of the 11 stations in Shanghai eported a hot day 16 times in 1983, and among these there were 13 large-scale hot days, accounting for 81. 3%. In 2003, however, there were 45 hot days reported but only 29. 5% of these were large-scale hot days. Thus, it seems that the growing UHI increases the number of hot days around the city center, but large-scale hot days are not increasing. This provides strong evidence that the warming is local in nature, caused almost entirely by the UHI, and not as a result of a larger, regional warming pattern. The urban heat island and excess death The relationships between heat and human health are ummarized in Table 3, which illustrates the excess mortality rate, the number of heat waves, and the average maximum temperature for each heat wave from 1998 to 2004 in each region. Population-adjusted excess mortality in each region, along with UHI intensity, has been plotted for each year in Fig. 6. The excess deaths in the central urban region are higher than those in the suburban and exurban sites, which coincide well with heat island intensity, especially in the two severe heat waves in 1998 and 2003 (Tan et al. 2004, 2007). For example, with the 1998 heat wave, the excess mortality rate in the urban area is about 27. /100,000, compared to only 7/100,000 in the exurban districts. Furthermore, a comparison between excess deaths and the spatial coverage of the two heat waves in 1998 and 2003 (Fig. 7) shows that the extent of high temperatures played an important role in the number of excess deaths. In general, the more stations that reported hot days, the higher the number of excess deaths. In 1998, Shanghai experienced long duration, large-scale hot days with more than nine districts experiencing temperatures above 35 °C for nine consecutive days from August 8 to 16. As a result, excess deaths increased sharply with a maximum value of 53 deaths observed on August 16. On the other hand, in 2003, there were frequent hot days, often with a large number of consecutive days, but these heat waves were not often experienced by a large number of stations. Thus, the spatial coverage of the 2003 event was much smaller than that observed in 1998, resulting in fewer deaths. Discussion The urban heat island effect is among the most welldocumented impacts of human activity on local climate. As Int J Biometeorol (2010) 54:75–84 large-scale climate change continues, the UHI is very likely to exacerbate the warming, resulting in more frequent and ore intense heat waves (Wilby 2003). Research on the UHI has typically focused on tropical or mid-latitude cities for the dual purposes of understanding the dynamics of the energy balance in the urban boundary layer and its application to issues related to urban pollution, energy conservation, and the prevention of heat-related health problems or deaths (Buechley et al. 1972; Smoyer 1998). Here, the comparison between meteorological monitoring stations both inside and around the city of Shanghai revealed the large impact of the urban heat island effect on temperature, heat waves, and human health.The results demonstrate that the meteorological sites (city center and its surroundings) have experienced different degrees of warming over the period of record as a direct result of increasing urbanization and a more pronounced heat island. Additionally, we find that the hottest days (above 35 °C), as well as prolonged heat waves, are more likely to occur in urban locales. The UHI is often referred to as a nighttime phenomenon with the highest values of the UHI intensity occurring between midnight and early morning, especially in winter. This has been documented in the United States, Italy, and eyond (Basu and Samet 2002; de’Donato et al. 2008), highlighting that the major differences between urban and rural areas were measured during the night. However, for Shanghai, our results show that the heat island is often more pronounced in the daytime during the summer, with the highest urban–rural d ifferences ranging from 0. 5 to 2. 0 K at noon or in the afternoon, coinciding with the timing of maximum daily temperature. The increased thermal loads found in urban areas may be a direct factor for heightened levels of human mortality (Clarke and Bach 1971; Jones et al. 1982; Conti et al. 2005).Additionally, previous studies note that virtually all causes of mortality increase during extreme heat waves, including respiratory failure and circulatory system failure from heart attack or stroke. The results of this study demonstrate that heat-related mortality (all-cause deaths above the baseline) is often much higher in the inner city than in outlying environs during heat waves, coinciding with heat island intensity. Inhabitants of urban areas may experience sustained thermal stress both day and night as city surfaces often heat up quickly during the day but are slow to cool at night (Sheridan and Dolney 2003).There is emerging evidence that the urban population shows greater sensit ivity to heat compared to those in rural regions. For example, analyses of the 1995 Chicago heat wave have shown that the relative risk for a heat-related hospital admission in the city was nearly two times higher compared to the suburbs (Rydman et al. 1999). Similar results were found in 2003, where heat wave mortality was greater in 2 20/7– 24/7 36. 1 ?2. 51 2 19/7– 31/7 36. 5 0. 93 4 22/8– 26/8 36. 1 2. 57 4 19/7– 6/8 36. 6 4. 32 2 16/7– 31/7 36. 2 3. 33 Heat waves Longest duration Tmax( °C) Excess mortality rate (1/100,000)Heat waves Longest duration Tmax( °C) Excess mortality rate (1/100,000) Heat waves Longest duration Tmax( °C) Excess mortality rate (1/100,000) Heat waves Longest duration Tmax( °C) Excess mortality rate (1/100,000) Heat waves Longest duration Tmax( °C) Excess mortality rate (1/100,000) 2000 2004 2003 2002 2001 1999 3 7/8–17/8 36. 8 27. 30 0 Heat waves Longest duration Tmax( °C) Excess mortality rate (1/100 ,000) Heat waves Longest duration Tmax( °C) Excess mortality rate (1/100,000) 1998 Urban Item Year 36 5. 60 36. 1 6. 39 2 19/7– 31/7 4 28/7– 3/8 2 20/7– 24/7 35. 3 2. 29 3 25/7– 29/7 35. 7 ?0. 89 0 2 8/8– 17/8 6. 9 18. 20 0 MinHang 35. 8 ?0. 23 36. 9 5. 85 3 17/7– 7/30 2 21/7– 29/7 1 20/7– 23/7 36. 8 ?0. 25 1 28/6– 2/7 36. 1 2. 29 0 2 7/8– 15/8 36. 4 18. 99 1 9/9– 11/9 35. 3 0. 40 BaoShan 35. 9 1. 00 36 1. 64 3 20/7– 25/7 2 20/7– 24/7 35. 7 0. 91 2 28/6– 2/7 36. 1 0. 95 1 14/7– 16/7 36. 4 0. 41 4 19/7– 25/7 1 8/8– 16/8 37 15. 82 0 PuDong 36. 2 2. 89 36. 3 17. 39 3 17/7– 1/8 4 19/7– 4/8 1 20/7 – 23/7 36 0. 41 3 28/6– 2/7 36. 2 4. 82 0 1 8/8– 16/8 36. 4 13. 08 0 JiaDing 35. 8 ?0. 57 35. 7 1. 42 2 20/7– 25/7 1 25/7– 29/7 0 0 0 1 8/8– 15/8 35. 9 9. 21 0 ChongMing 0 0 0 0 0 2 10/8– 16/8 36. 2 12. 81 0 NanHu iTable 3 Summary statistics of excess mortality rate and mean maximum temperature in heat waves, broken down by region and year 36. 2 3. 41 0 2 28/7– 30/7 1 21/7– 24/7 35. 4 0. 94 1 29/6– 2/7 36. 1 1. 89 0 1 8/8– 17/8 36. 3 8. 01 0 JinShan 36 0. 22 36. 6 5. 89 2 17/7– 31/7 4 28/7– 3/8 1 21/7– 23/7 35. 9 1. 09 2 28/6– 3/7 36. 4 2. 85 0 2 7/8– 16/8 36. 5 12. 51 0 QingPu 36. 5 ?0. 39 27/8– 30/8 35. 9 0. 00 1 23/7– 25/7 36. 2 1. 56 1 28/7– 4/8 36. 2 3. 16 2 17/7– 31/7 0 0 0 2 9/8– 16/8 35. 8 7. 00 0 FengXian 3 1 21/7– 24/7 35. 8 0. 20 1 29/6– 1/7 36. 1 3. 82 0 1 8/8– 17/8 36. 4 18. 15 0 SongJiang Int J Biometeorol (2010) 54:75–84 1 Int J Biometeorol (2010) 54:75–84 82 30 exposure to heat in the city center, resulting in elevated levels of heat-related mortality in urban regions. This study was subject to several limitations. First, many approaches such as absolute threshold temperature (Huynen et al. 2001), relative threshold temperature (Hajat et al. 2002), and synoptic climatological approaches (Sheridan 2002; Sheridan and Kalkstein 2004) can also be used to define heat waves. Although our definition is somewhat arbitrary, it was chosen to correspond with the Chinese Meteorological Administration’s heat warnings, which are ssued when maximum temperatures are forecast to exceed 35 °C. Thus, Chinese residents are more familiar with the definition used here. Second, the effects of the UHI on heat-related mortality are multifaceted, and we did not examine data measuring air pollution, other meteorological factors such as cloud cover or humidity, or the potential impacts of socioeconomic status or other social variables. Therefore, no confounding effects were evaluated. Previous research indicates that human mortality is impacted by both ambient meteorological conditions and atmospheric pollutant levels.The stagnant atmospheric conditions common during heat waves can trap pollutants in urban areas, exacerbating the negative impacts of the heat wave 1998 2000 2001 20 2003 15 2004 10 5 0 -5 3. 5 4 4. 5 Fig. 6 The excess mortality rate and the heat island intensity for heat waves in Shanghai urban regions compared to suburban areas in Switzerland (Grize et al. 2005). Our previous investigation revealed that observed differences in heat-related mortality between two severe heat waves in 1998 and 2003 could be traced to the longevity of the heat; prolonged exposure to heat is more stressful to human health than isolated hot days (Tan et al. 007). Here, we confirm that the UHI serves to enhance the prolonged (a) 1998 20 500 The number of the sites with Tmax? 35 °C The number of the sites with Tmax? 35 °C 16 400 excess deaths 300 8 200 4 100 0 0 9-8 9-12 9-4 8-31 8-27 8-23 8-19 8-15 8-7 8-11 8-3 7-30 7-26 7-22 7-18 7-14 6-28 -200 6-24 -8 6-20 -100 6-16 -4 excess deaths 12 Date (b) 2003 500 20 The number of t he sites with Tmax? 35 °C 16 The number of the sites with Tmax? 35 °C 400 excess deaths 300 8 200 4 100 0 0 Date 9-12 9-8 9-4 8-31 8-27 8-23 8-19 8-15 8-11 8-7 8-3 7-30 7-26 7-22 -200 6-28 -8 6-24 -100 6-20 -4 excess deaths 12 6-16 Fig. 7 The number of excess eaths versus the number of stations reporting hot days during the summers of 1998 (a) and 2003 (b) 7-18 3 7-14 2. 5 7-6 2 7-10 1. 5 Urban Heat Island Intensity(K) 7-10 1 7-2 0. 5 7-6 0 7-2 excess mortality(1/100000) 25 Int J Biometeorol (2010) 54:75–84 (Anderson et al. 1996; Piver et al. 1999; Johnson et al. 2005). Air pollution such as ozone and PM10 compound the heat–mortality relationship, and previous research suggests that between 21 and 38% of the excess deaths observed during the summer 2003 European heat wave were attributable to these pollutants (Stedman 2004). However, it remains difficult to separate the impacts of eat and pollution on human health, and it is possible that some of the heightened urb an mortality totals in this study were partially a result of elevated concentrations of airborne pollutants found in the city center. Conclusion There is no doubt that the urban heat island (UHI) has a profound impact on human health. The UHI serves to enhance the intensity of heat waves, which in turn adversely affects human health due to an increased exposure to extreme thermal conditions. As a result, heatrelated mortality is found to be higher in the city center compared to suburban locales. This research provides vidence that Shanghai local officials should be cognizant of the increased thermal loads experienced in urban regions and take appropriate action to help reduce the impact of heat on the population.

Social Media – A Blessing or a Curse Good [time] everybody. Today, I am going to discuss the benefits of social media but I shall also address the issues, as you would ve seen if you have added me as a Facebook friend. The idea of social media is a new one; The first recognisable one was created in 1997 but it was 2 years later that the first blogging sites became truly popular. From here, the social media tree has branched out, allowing us to develop new meanings for words such as follow or tweet and to gather newer terms like reblog and has given us access to instant messaging, allowing all users to connect easily. Sounds rather great, doesn t it? Connecting with friends and family or blogging about your fancy dinner that your partner took you out to is not the only thing that happens on these websites. Cyberbullying is an issue that plagues our world, and it is estimated that 22 million students experienced it in 2011. 3.9% of these people reported being cyberbullied every single day. 1 in 6 teens say they have been contacted online by someone they did not know in a way that made them scared or uncomfortable. With 95% of all teenagers on social media, there are millions of targets for these online bullies. A couple of you might be surprised to hear that this goes on. I m sure you weren t aware that whilst you were catching up with Geraldine who you haven t spoken to since secondary school, a teenager is possibly being bullied to literal

Aging, Death, And Dying - 1746 Words

The goal of a research paper is to obtain different views and facts about a certain topic. Aging, death, and dying is an extremely broad topic with ample of books, movies, pieces of art, and even television shows. Edgar Allan Poe s For Annie happens to be one piece that relates to the topic of aging, death, and dying. An analysis opens up the background of Edgar Allan Poe, the meaning of the piece as a whole, and the different views of the piece. Edgar Allan Poe was born January 19, 1809 in Boston, Massachusetts. His parents were both known actors. Poe was a fiction writer, a critic, and a poet. He writes in a unique and dark way with emotion and drama. His works have a theme that occurs continuously with death, lost love or both (Silverman). He is different from other poets. Poe is very well-known by people all over the world. When people think of Poe, they think of a mad man or someone that is insane. Poe is known for his troubled mind, afflicted by alcoholism and bipolar affective disorder (De Oliveira 84). Events in his life are more than likely the reason he writes in the style he does. His works are unlike many others. Poems by Poe have strange characters and even more strange story lines. Stories by Poe are more terror and his poems are more haunting or odd (Silverman). While reading this poem you have to take into consideration the type of writer Poe is. He is known for his gloomy or dark writing. It is a different writing style.
