Environmental Science Global Warming Effects on Small Melanesian Isla

Question: Discuss about the Environmental Science and describe the report for Global Warming Effects on Small Melanesian Islands. Answer: Summary The islands of Melanesia hold two of the thirty five global biodiversity hotspots with huge number of endemic species. Global warming and climate change are exacerbating the challenges faced by these biodiversity of Melanesia. In this report, the potential impacts of global warming and their harmful effects on the biodiversity of small Melanesian islands have been identified. According to the International Union for Conservation of Nature and Natural Resources(IUCN) more than 305 terrestrial species are threatened by severe climatic changes. Tropical cloud-montane forests, rainforests and dry forests of Melanesia are estimated to completely disappear by the year 2100 with resultant global damages of the endemic biodiversity. Introduction There is now plenty of evidences that climate is changing due to global warming and is impacting global biodiversity. The world is becoming warm. Over the past century, earths average temperature has amplified by more than 1Fahrenheit (0.7 Celsius). There are ten prime indicators of a warming world. If among these indicators seven are rising and three are decreasing, that means the world is becoming warmer. The seven currently rising indicators are humidity, temperature over the ocean, air temperature near troposphere, sea surface heat, ocean heat content, temperature over terrestrial and sea level. The decreasing indicators are glacier retreat, snow covers and sea ice amount. The Pacific Melanesian islands have diverse and complex biogeography history, which have led to the evolution of a unique biodiversity. East Melanesian islands and New Caledonia constitute two global hotspots. But this biodiversity is in the verge of irreversible damages and extinction as a result of global war ming and climate change. Effects on small Melanesian islands Melanesia is a sub-region of Oceania in the western side of Pacific Ocean. Melanesian topography includes the Solomon Islands, Vanuatu,Fiji,New Caledonia and Papua New Guinea. These small islands are biologically diverse and have a very high proportion of endemic species (Taylor and Kumar 2016). According to Bellard et al. (2014), Melanesian islands is in fact without a doubt one of the worlds most vulnerable lands when it comes to the risk of disasters due to global warming and climate change. Warming, El Nio and La Nia Global warming in western tropical Pacific regions will closely follow the proposed global average warming rate of 3.2-7.2Fahrenheit (1.8-4.0Celsius) by the year 2099 (Viles and Spencer 2014). Significant decline in the amount of glaciers in New Guinea has already been observed and current projected warming of 1Celsius suggests that freezing altitudes have now moved upslope with increased temperature and lessened rainfalls (Taylor and Kumar 2016). In Melanesia, El Nio results in drier and hotter terrestrial weather but relatively cold sea temperature. On the other hand, La Nia in Melanesia generates wet conditions on land and much increased temperature of sea surface. El Nio and La Nia cycles which is known as ENSO, have major effects on the climate of Melanesia. Regional climates in the Melanesian islands are strongly influenced by ocean circulation and ENSO (Kingsford et al. 2011). Studies found large-scale changes in ocean circulation patterns, increased temperature, wind direction and speed, rainfall changes, sea-level rise and increased intensity of tropical cyclones as result of global warming. (Allen 2015). Rising of sea-level A study of the International Pacific Research Centre (IPRC) revealed that sea-level in the northern portion of Melanesia have been rising quicker than the mean global sea-level increase and predictions are that sea-level will continue to rise faster than the global average. The Melanesian small landmasses are highly vulnerable to sea-level rise. Sea level rise is causing inundation of coastal habitats for flora and fauna, shoreline erosion and stronger storm surges that can destroy low-lying small islands (Barros et al. 2014). Melanesia contains some of the worlds largest remaining traces of coastal mangrove habitats. As described by Alongi (2014), mangrove ecosystem is extremely affected by the impacts sea-level rise. In unobstructed regions mangrove species zone migrate landward to maintain their suitable environmental conditions. But new colonizing rate gets affected in the presence of obstacles such as seawalls or shoreline protection structures. This causes narrow mangrove density or extirpation of the precious mangrove community. Rising sea-level is also increasing the ground water salinity and pushing salt water further upstream in these islands. This increased salinity is making water undrinkable and harming animals, plants and aquatic plants species which cannot tolerate this increased salinity. Sea level rise holds great threats to coastal ecosystem and the biota that ecosystem supports. With a projected rise of between 0.18 meter and 0.59 meter by the completion of this century, species that depend on low-lying coastal habitats of small Melanesian islands, are particularly at risk of disappearance (Taylor and Kumar 2016). Increase in SST and coral bleaching or damages The worldwide decline of coral reefs is an alarming effect of increased in sea-surface temperature. Sea surface temperature (SST) is warming faster towards the equator and less rapidly near the higher latitudes. In the ocean, temperature rising is about 0.18 Fahrenheit (0.1C). This amplified temperature has transpired from the surface to a depth of about 700 meters (2300 feet), where maximum marine life grow well (Taylor and Kumar 2016). Evidences suggest among all the marine organisms most vulnerable to temperature changes is corals.At even a slight persistent rise in temperature, corals eject their symbiotic algal community (zooxanthellae) and get bleached. It causes loss of many of coral species and reef fishes in Melanesian biodiversity hotspots are at extreme risk from coral species loss (Holbrook et al. 2015). While the entire Melanesian oceans and reefs are becoming warmer, resulting in an increase event of coral bleaching, northern part Melanesia is likely to experience more intense, frequent and persistent coral bleaching event than the southern island regions. Extensive period of La Nia condition due to climate change in Melanesia gives rise to much hotter sea surface temperatures, which results in more frequent and intense coral bleaching. Ocean acidification Ocean water naturally absorbs carbon-di-oxide, but the amount of current human-generated carbon-di-oxide emissions is so enormous that it is altering the chemistry of this planets oceans. Carbonic acid is procedures when ocean water absorbs carbon-di-oxide and thus, oceanic water surface have become more acidic in last decades, causing a reduction of 0.1 pH (Alongi 2014). This type of massive changes have not befallen on this planet for millions of eras, and never on such a short time span. Ocean water acidification decreases the obtainability of calcium carbonate essential for marine creatures like zooplanktons, corals, clams and sea urchins etc. Acidification also hampers the respiratory system in fish and also adversely influence their food source. The most recent scientific findings revealed that calcium carbonate levels in ocean of the Melanesian islands will become minimal by the year 2070 and much earlier in the higher latitudes. Catastrophic events like this will cause slowin g down or reversal of shell and coral reef formation, perhaps bring about major disturbances in marine food webs. Ocean acidification is also an adverse condition for mangrove ecosystem (Alongi 2014). Effects of climate change on terrestrial biodiversity Terrestrial plant and animal species of Melanesia are specifically vulnerable to climate change because of higher levels of endemicity in the islands (Keppel et al. 2014). Researches have evidences that Melanesian island biota are generally at higher risks of extinction and magnitude of extinction is greater than the continental rate for mammals and birds (Loehle and Eschenbach 2012). The species diversity of these islands are limited in their abilities to cope with climate change due to small geographical ranges, narrow genetic variations, reduced species richness and small colonizing population (Jupiter et al. 2014 and Loehle and Eschenbach 2012). The small land areas of these islands offers smaller realized niche pace which generally translates into very small ranges for islands organisms mainly for endemic species. As a result, harmful effects of climate change is affecting the entire habitat of island biota more readily than the continents (Harter et al. 2015). New Caledonia embraces around 3371 native vascular plat species among them 74% are endemics. Increasing atmospheric temperatures are having considerable impacts on those endemic species that are constrained in few regions. Over 20% of gymnosperms and angiosperms in New Caledonia fall into this set. Climate change associated impact like increased frequency and severity of tropical cyclones are immensely affecting the relative abundance of species and supporting disturbance-preferring species and thus, new forest turnover rates (Taylor and Kumar 2016). Species vulnerability modelling showed that organisms of tropical rainforests and dry forests are much more susceptible to climate change than species of other habitats. Tropical dry forests contain many endemic floras with very limited geographic boundaries such as Ancistrachne numaeensis and Diospyros sp. in New Caledonia and highly endangered Guettarda wayaensis and Cynometra falcate in Fiji (Iucnredlist.org 2016). In New Caledonia more than 82% of rainforest organisms are endemic and the changing rainfall regime is imposing immense adverse effects on the ecosystems. Rainforest plants with narrow geographical range such as Lavoixia macrocarpa and Pritchardiopsis jeanneneyi have higher risks of extinction due to altered ecosystem (Cahill et al. 2012). Tropical ectotherms have limited adaptability and environmental temperature has a strong influence on their physiological functions like growth, movement and reproduction. Several species of lizards, snakes and approximately 35 species of frogs of the PNG regions have small populations on islands, making them highly vulnerable to extinction due to climate change related habitat loss (Taylor and Kumar 2016). Mammals of Melanesian regions are directly affected due to changing climates, mainly increased temperature. The native mammal biodiversity of these islands is composed of marsupials, rodents and bats. Temperature elevation and sea-level rise gradually destroying the ecosystems and many vertebrates (37 to 118 endemics) facing the threat of extinction (Wetzel et al. 2013). Mountain-restricted birds with constricted elevational range are specifically vulnerable to the impacts of climate alteration as they have small zones of occupancy. A study a the freshwater and terrestrial bird species of Melanesia indicated that more than 50% were moderate to strong vulnerable species due to climate change impacts (Ã…Å ¾ekercioÄÅ ¸lu et al. 2012). Shifts in normal climatic conditions are also affecting seasonal availability of food and changes in these cycles could affect the entire population of birds. Many small islands of Melanesia provides nesting zones for reproduction and breeding to migratory birds like Numenius tahitiensis. Their nesting ground could be severely affected if increased temperature, elevated sea-level and intense cyclones destroy ecosystems of small islands (Taylor and Kumar 2016). Impacts on human beings Ocean warming, floods, tropical cyclones, droughts are expected to have intense impacts on agriculture system of these islands. Climate change and soil degradation and deterioration of soil fertility as a consequence of amplified precipitation damagingly impacting on agriculture and food security. Systematic evidences shown that due to the lack of adaptation, high islands like Fiji, could undergo damages around USD 23-52 million every year by 2050. In addition, fisheries contribute considerably to the GDP and rural livelihood on many of these islands. More frequent and intense cyclones and increase in sea level is adversely impacting inshore fisheries especially in rural zones (Allen 2015). Water resources in Melanesian island are at risk to fluctuations and changes in climate because of their availability, limited small sizes, geology and topography, specifically in rainfall. With a 2-4 Celsius increase in temperature, projected economic damages aggregated upto one billion USD in damages to water resources. Drinking and agriculture water stresses formed by climate change will have extreme impacts on poor rural society dependent on water resources for their livings (Allen 2015). Conclusion The small Melanesian islands contribute a negligible amount of global greenhouse gas emission but experiencing disastrous consequences of climate change from global warming. These islands contains many endemic species many of which are listed in the IUCN red list of data-book. New extinctions are still being recorded in this part of lands. The unique bio-geographical process on Melanesian islands have given rise to such high level of endemism and also endowed organisms with characteristic traits that make them highly vulnerable to climatic changes. The rapid frequency of weather change, restricted ability for adaptations and limited proportion of fitting habitat on these small landmasses propose that consequences of global warming could be severe for the biodiversity of Melanesian region. While it is vital to decrease the emission of greenhouse gases, it is equally significant to take radical steps to mitigate the estimated impacts of global warming on biological diversity.

Twelfth Night Essay Thesis Example For Students

Twelfth Night Essay Thesis Act II, Scene v is one of the main scenes in the play and is the scene where Malvolio is set up by Sir Toby, Sir Andrew, Sir Fabian and Maria. They place a letter for him to read pretending to be Maria. Malvolio instantly falls for this and does all of the ridiculous things in the letter such as wearing cross gartered yellow stockings. This scene has the main characters of the group; Maria, Fabian and Sir Toby while Sir Andrew is silenced at every comment he makes this builds up the personalities and helps with the powerfulness of the scene. This scene is dramatically powerful for many reasons, one of them is comedy, which is very clear in this scene, as when Malvolio is talking to himself, this is funny to the audience not only as he is talking to himself but the role-play he does and the status he gives himself married to Olivia having been three months married to her, sitting in my state and as the hero he talks about Calling my officers about me, in my branched velvet gown, having come from a day-bed, where I have left Olivia sleeping. When he is reading the letter from (he thinks) Olivia. This shows Malvolio as a daft and ridiculous character both for the fact that he fell for the letter and the way he reacts. He also gets on everyones nerves by reacting so grandly and preening himself which annoys sir Toby. This is because Toby is not entirely in the right as he does drink too much and we as an audience get both perspectives and the view on sir Toby by everyone else. Both by Malvolio telling off Toby for drinking too much and by Malvolio always telling Olivia of them to get her on his side. Another aspect of the play and this scene that makes it dramatically powerful is love, The first aspect is Malvolios which we originally think is love for Olivia, is found out just to be for money and power and not at all for Olivia herself, and in some ways this justifies what happened to Malvolio but I still think that the joke went to far and this is quite good for dramatic power, but at this point it is still a joke and has not gone to far yet it only goes to far later in the play when Malvolio is locked away for being mad. This contributes to my wider understanding a lot as it is an important scene and shows not only how everyone hates Malvolio but also how they react to him and get back at him. By using the letter and getting Maria to pretend to be Olivia, This builds up character relationships, and shows the audience that Malvolio is only interested in Olivia for the wealth and power but not for love of Olivia, tis but fortune, all is fortune.. It also shows you how the others react with each other; Maria and Sir Toby being the ring leaders, Maria writing the letter and joining in heavily with the prank, and sir Toby having reason and also contributing to the group, with Fabian in the background and Sir Andrew being shot down at every suggestion and silenced every time he tries to talk. It gives meaning to the later part of the play where Malvolio is locked up as it shows firstly why he is locked up but also that it was not his fault and we also know who is to blame. This gives us another perspective as the audience because only we and the plotters know that it was all a joke. Although this is a joke the plotters still have their strong hate for Malvolio as seen with Pistol him, Pistol him and Fie on him! Jezebel!.

History of Womens Basketball Essay Example

History of Womens Basketball Essay In the late 19th century, a thirty-one year old graduate, James Naismith, with great vision to create an indoor pastime was given that very opportunity. Inside the gymnasium of Springfield College, formally known as International YMCA training school, the sport of Basketball was created. With nothing but a few active college students, a soccer ball, two peach baskets as goals, and thirteen rules to govern thus giving birth to basketball. News of the 30 minute game began to rapidly spread and it was an instant success. Without the well-represented international background of the college, basketball would not have been introduced to many places around the world.James Naismith invented basketball in December of 1891. Less than one year later, women physical education students at Smith College were introduced to the game. Soon women were playing the new sport across the country. Fast forward to the early twenty-first century. Women and girls play basketball in parks and recreation leagues, high school, college, in the Olympics, even in the professional Womens National Basketball Association (Jenkins). The journey from Smith College to the WNBA, however, was a long and difficult one, full of false starts and broken promises. Almost from the beginning, women were constrained in their opportunities to play basketball. Physical education professionals argued that, â€Å"Athletic competition was unladylike and basketball too strenuous for females† (Jenkins). Few colleges fielded intercollegiate teams, and the sport struggled at the high school level. The women who could play were forced to compete under rules that limited their ability to run the entire court. Basketball was not always a beloved activity for women. With a successful target audience of young male athletes, basketball was faced with the issue of implementation into larger associations such as college or professional sports.

Get the Lead Out of Hunting

Get the Lead Out of Hunting The Lead Problem Throughout modern firearms’ evolution, lead has been the material of choice in the manufacture of ammunition. The high density of lead and its deformation characteristics give it desirable ballistic properties. For hunting purposes, lead is used to make the small, round shot packed in shotgun shells, and is the main component in the bullets used in rifles. What makes lead less than ideal, however, is that it is quite toxic. In 1991 in the United States (and in 1997 in Canada) lead shot was banned for waterfowl hunting. Up until that point, tons of lead shot had been raining on wetlands all over the continent each hunting season. As ducks were foraging for food in the sediments at the bottom of wetlands, they would ingest lead shot and many would eventually die of acute lead poisoning. Bird hunting upland, for example for pheasant, grouse, or quail, was not included in the 1991 ban. With upland hunting, the shot used does not become concentrated in discrete locations and it was not believed to be problematic to the degree waterfowl shot was. The same might have been believed for rifle bullets, which are to this day mostly made of lead. However, there are real environmental and health hazards associated with the use of lead for any type of hunting, and many hunters are changing their habits accordingly. How Lead Bullets Work In hunting rifles, the lead bullet is shot at high pressure into the target. At that point the collision with the flesh of the animal deforms the bullet, turning it into a wide, flat blob, killing the animal quickly if the shot is well placed. However, there is a key problem with lead bullets: when the bullet hits its target, it looses energy by deforming and breaking up, with dozens of small lead fragments ending up lodged in the entrails and the meat of the animal. These fragments can be as small as sand grains, and they are often found over a foot from the wound channel. Environmental Effects When a hunter guts a large mammal, the lungs, kidneys, digestive track, and other organs are left in the field, and with them tiny lead particles. These â€Å"gut piles† are fed upon by scavengers like foxes, coyotes, ravens, red-tailed hawks, eagles, and many other birds and mammals. The small lead bits are accidentally ingested as well. A very small lead fragment in an animal’s gut will be dissolved by the digestive juices, elevating blood lead levels to several parts per million, which is enough to kill a bird as large as a bald eagle. Anyone who has been in rural areas on opening day of a deer hunt can appreciate how many gut piles are left behind in the woods and imagine how many scavengers must have elevated lead levels in their blood.   Health Effects Traditionally, when big game hunters butcher their quarry they carve out the meat about two inches around the entry and exit wounds. When researchers used portable x-ray equipment to look at deer carcasses killed by rifle, they found very small lead fragments far away from the bullet wounds. These fragments then end up in the meat consumed by humans. Even packaged ground venison examined with x-ray technology showed a peppering of very small lead particles, small enough to be unnoticed by the unsuspecting eater, but large enough to cause dangerous health effects. Even at low concentrations, lead in adult humans interferes with renal function, affects learning and thinking, and disrupts our reproductive system. In children, nervous system development is impacted, and there is no such thing as a safe blood lead level. In communities getting a substantial proportion of their protein from wild meat, blood levels with significant lead levels are commonly found. The Solution For shotgun shells, various non-lead materials are now available for upland small game hunting, including steel, bismuth, and tungsten. For large game hunting, all-copper rifle bullets are now on the market for most calibers, and are gaining rapidly in popularity. These bullets retain their mass when entering an animal, without losing small pieces like lead does. Non-lead ballistic characteristics are very acceptable for most hunting situations, and the modern copper bullets have been field proven to be at least as lethal as conventional bullets. The only disadvantage of non-lead bullets is their cost, which is on average about 40% higher. In 2008, California banned lead ammunition in areas where California Condors live, as lead was identified as one of the major threats to that species’ existence. The ban will be extended to the entire state by 2019. For More Information Web resource discussing the science: Hunting with Non-lead. United States Geological Survey. Lead Poisoning in Wild Birds.

Essay Example mself, the particular case that would ostensibly be his most vital and characterize the heading of his future work, was that of drawing a line between the announcements, or frameworks of proclamations, of the observational sciences, and all different articulations (Keuth 2005). Popper wasnt the first researcher to consider this issue and, as we will see, his proposals contradicted what the acknowledged perspectives were encompassing the issue at the time. Here, we try to find simply why Poppers boundary was so essential. The essential system for division that Popper proposes, then, is that a hypothesis may be considered to be exploratory in the event that it can be misrepresented (Allday 2009). That is to say that a hypothesis must contain a characteristic testability; it must have the capacity to make expectations that can be gotten to through experimentation. Poppers strategy for boundary does not oblige that a hypothesis can ever be indicated, unequivocally, to be genuine, however it does oblige that through experimental testing a hypothesis can be demonstrated to be false (Popper 1974). Different theories have been formulated in explaining certain phenomenon in the world. There are distinctive perspectives of what executed the dinosaurs and different organic entities. Contention has encompassed the point and it has gotten to be troublesome for people in general (and the investigative world everywhere) to comprehend the issue because of the tangled array of information which appears to point in various bearings. Fortunately, the discussion has not hurt the investigation of mass termination causation, but instead has made it a dynamic and fascinating region. Each momentous new theory stands out as truly newsworthy in the media, and energizes scientists to dive further into the riddle.

The Aviator - Movie Review Example This article is a review of the movie looking into the themes, character, style and narratives. The information presented in this article is obtained from both primary and secondary sources. The primary source is through watching the films and trying it analyze the characters and finding out the themes. The secondary sources are the reviews that have been conducted by various authors on the movie. Different reviewers have given their views on the style and the representation of characters in the film. These sources were used to get the plot of the story and style used. The narrative style together with other techniques of film making is explored. The characters were then analyzed against each other (Marrett, 195). The different themes are then explored and the role each character played in the realization of these themes discussed. The movie starts when Hunges is a young boy where his mother tells him to take caution not to get a flue. Then in the year 1927, Hunges inherits his family fortune in California. He uses this fortune to design oil drilling bits a venture that made him a billionaire. Later when he was 22, he decided to invest in the film industry an area where he had a huge interest in. His first film was the silent Hells Angel which he works very hard to ensure that it turns out perfectly. His next film had some talking and was called The Jazz Singer. During this time, he also produced a sound version of the Hells Angel which became a major Hollywood hit. This was a key to entry into the Hollywood social network and he dated two Hollywood stars Jean Harlow and Katharine Hepburn. However, he did not quite fit into Hollywood and he decided to go back to designing aircrafts. He made new design and even risked his life trying out new aircrafts and flying around the globe. He even got into an accident ov er Beverly Hills when taking XF-11 for a test flight. He got major injuries that
