What are the potential effects of global warming in terms of climate change and how can they be arrested?
Global warming is a problem that threatens the whole world. Though it has had little noticeable impact on the world so far, its potential impact could be disastrous which is why global warming has become an issue ever present in the media and for governments. Global warming is not a new phenomenon. The sun warms the Earth's surface and to stop it over-heating the heat energy is radiated back through the atmosphere and into space. Gases such as carbon dioxide and methane trap some of this heat thereby warming the lower atmosphere, which in turn warms the Earth's surface. This is the 'greenhouse effect' and is essential to life, as without it the earth would be so cold it would be uninhabitable. However global warming is attributed to the greenhouse effect as the increase in greenhouse gases being released into the atmosphere by humans slowly warm the Earth, potentially changing the world's climate to more erratic, forcing many species into extinction, and making life much harder especially for people in developing countries (Woodford, 2006).
The prime potential consequence of the global warming in the context of climate change is the rising of the sea level. It happen when more sunrays in form of infrared will be trapped in the atmosphere by the greenhouse gasses like carbon dioxide. Cores of polar ice show that carbon dioxide is much, much higher than ever before in a quarter of a million years. It was once thought that such things went in cycles but not anymore as carbon dioxide content keeps growing higher (Al Gore, 2007). Then, the ice sheets, glaciers and icecaps like Greenland and west Antarctica will melt little by little and will directly increase the volume of the sea water. The melting process of the icecaps will become faster when larger surface area of the sea is exposed to the sunrays which result to a warmer ocean. Hence, the sea level will also increase as the water expands when it being heated (Woodford, 2006). According to Al Gore in an Inconvenient Truth, the major city like Beijing and country like Netherland will entirely awash in the sea if Greenland is completely melt. The melting of either icecap could raise global sea levels by approximately 20 feet (6 m), flooding coastal areas and producing 100 million refugees (Al Gore, 2007).
As the product of the global warming, our planet experiencing the 10 hottest years in atmosphere’s records which was occurred in the last 14 years (Al Gore, 2007). With the hot temperature that keeps rising, more frequent heat waves will be produced in the air (Riebeek, 2007). Massive heat waves can be a disaster to us especially in this condition of atmosphere. It was already happen in India and the European countries in 2003 and killed thousands of people. Other than the continents in the world, the ocean also face rising of temperature in recent years. According to Al Gore, the warmer ocean will produce a stronger storm. The process is really simple. When the storm went through warmer water, the wind velocity and the moisture content will increase. So, the storm will contain much energy and become a deadliest hurricane. In 2004, big hurricane has made all time record in various countries.
Eventually, there is still hope to address this global problem if we act right now. The damage is still reversible. What to do in the face of this global threat? We must reduce the emission of carbon dioxide (Woodford, 2007). Use or support the development of alternative energy sources such as solar, wind, tidal, and, yes, nuclear. Drive only hybrid and electric cars. The government should subsidize public transit and fares. Save energy in your houses. You can start by turning off the lights when not needed. All of the citizens in the world should take a big heed before it's too late. If the vast majority of the world's scientists are right, humankind has about ten years to avert a major catastrophe that could send the entire planet's climate system into an epic destruction involving extreme weather, droughts, floods, epidemics and killer heat waves beyond anything ever experienced – a catastrophe of our doing.
MOVE over aspirin: Australian researchers may be about to pull off the next medicinal makeover, after finding "very promising" evidence that paracetamol can protect against heart disease. The preliminary findings by a Sydney-based team suggest paracetamol, first marketed for pain relief in the 1950s, could help save lives by inhibiting an enzyme already used as a sign of a patient's heart attack risk. Although the enzyme, called myeloperoxidase, plays an important role in the body's immune system, it produces hypochlorous acid, a free radical that damages tissues when produced in excess and is strongly associated with heart attacks. Searching for compounds that could block the enzyme, the researchers found that paracetamol worked remarkably well, at least when mixed with human cells in test tubes. They now plan clinical trials on patients to see if those taking paracetamol also show reduced levels of hypochlorous acid, and have better health outcomes. If the research confirms a protective effect for paracetamol, it would repeat the remarkable reinvention of aspirin, which reclaimed its place in the limelight following evidence it cut the risk of heart attacks and stroke. Since then, further research has suggested other benefits, including protection against colorectal cancer, breast cancer and Parkinson's disease. However, doubts have since resurfaced over whether the benefits of healthy people taking aspirin to prevent heart disease outweigh the risks. Aspirin has been linked to stomach bleeding and the aggravation of ulcers. Paracetamol has risks of its own, notably kidney and liver damage, if taken in overdose. Heart Research Institute deputy director Michael Davies, who led the new research, said the results were "very promising" and paracetamol had "enormous potential". National Heart Foundation chief medical adviser James Tatoulis said the research was "new and is very convincing". "There is great promise and potential for this safe, cheap and widely available medicine to contribute to the reduction of coronary heart disease in the community," he said. Summary and Critique: This article is mainly about the medical development in the country. The research of the paracetamol is been made. They found the benefit and potential of it. Paracetamol can prevent heart attack by preventing the overproduce of hypochlorous acids. It is the major factor that lead to heart attack. This article also explained how the medicine work in human body. Further research has found that it can give protection to us from many other dangerous diseases. Onthe other side,it also has it own side effect when we take it overdose. Based on my opinion,the introduction and the review of the medicine is straight to the point and easy to understand. The explaination of the reaction in human body is very specific and can be understand easily by a non-medic person.
The Richmond High Oilers have not had a good record, winning only four games last season, and it's time for a change in management. Ken Carter (Samuel L. Jackson), a record-maker when he attended Richmond, is looking into possibly taking the job as their new coach, and after watching them play his son Damien's (Robert Richard) high school St. Francis and witnessing the game almost turn into a brawl, he can see they are in dire need of some leadership. He decides to take the job, under a few conditions. The players will sign a contract agreeing to keep a minimum 2.3 grade point average, go to every class, and sit in the front row. He will have access to progress reports on all of his players from their teachers to make sure they are honoring the contract. This announcement doesn't
go over too well at the first practice, and Carter loses a few players right off the bat, including last year's high scorer Timo Cruz (Rick Gonzalez). In Carter's mind, this is only a minor setback, and he starts the team on a regiment of hustling up and down the court and game fundamentals.Needless to say, the team does a turnaround by focusing on the basics, and their progress is shown in quick-cut sequences of basketball action. Never do these sequences feel like a game, only a highlight reel, and as much a letdown these scenes are, the bulk of the movie consists of the players and their coach off the court. Here Mark Schwahn and John Gatins' script shows familiarity and simplification. Damien transfers to Richmond, and after the initial debate between he and his father, his only purpose is to be caught later with the team at party after winning a tournament. The only players' lives to have any screen time are Cruz and Kenyon Stone (Rob Brown). The former has an obscure relationship with his cousin involving money being passed underhand, while the latter tries to manage his life with pregnant girlfriend Kyra (Ashanti). Neither story effectively conveys the difficulties and perils of life outside of the school environment.
The movie finds some footing when Carter discovers that members of his team have been skipping class and failing to honor the GPA requirement of their contract. In response, Carter locks up the gym, cancels games, and sends his team to the library instead of practice, where teachers are awaiting to set the boys' academic lives straight. Carter tells them startling statistics of graduation rates, college admission denials, and prison sentences, and his logic just makes good sense. So, Cruz finds his way back, Stone's conflict with his girlfriend is relieved in an insultingly simplistic way, and there's the obligatory big game in which more of the game is shown than before, but this time it comes across as an extended highlight reel.
The movie even ends with a coda telling us what happened to the half or so of the team that did go off the college, and from Carter's reciting of statistics earlier, it doesn't seem like much of a change from the status quo.
He is actually the hero of this romance and historic movie. I believe that he is the one that brought the most influence in the whole story. He appeared to be a strong, strict but gentle and kind-hearted man in ‘Australia’. He is a very experienced in droving cattle. He has been a leader in droving thousands of cattle for Sarah Ashley. He also might be the only white man that doesn’t discriminate the aboriginal people on the land. He has had a wife from this kind of race people which is already dead. He also has a brother-in-law, name Magarri (David Ngoombujarra), the one that always with him whether in a good or a bad condition. He also never missed to back up Australian aborigine when the other people discriminate him such as when his aboriginal friend is not allowed
him to go in a bar.He was sent by Maitland Ashley to pick up his wife, Lady Sarah Ashley (Nicole Kidman). That is the first times the two people from opposite ends of the globe meet. They couldn’t be more different - yet they find their lives inextricably intertwined as they embark on a remarkable journey across hundreds of miles of the country’s most brutal terrain.
The Drover started to play his role as a hero in this movie when Sarah Ashley lost her beloved husband. He was the one that support her morally and physically. Then, a special kid name Nullah (Brandon Walters) appeared between them. They went through their journey together. The Drover acted as a partner and a father to Sarah Ashley and Nullah. He became a leader whenever they go. He was also the one that saved Nullah from the Mission Island when the Japanese attacked Australia. At the end of the movie, they were reunited and lived happily, thanks to the Drover.
All behave yourself especially syafiq!!
