The Threat Of Global Warming

As the threat of climate change continues to grow the world is desperately looking for an alternative source of energy. There are numerous promising replacements, but nuclear energy is by far the most opposed. Despite the fact that Australia has never contained any nuclear power plants, uranium produced energy and mining have been a highly debated topic in the continent for decades due to the concern over safety and economics. If the aim is to reduce the climate impact of electric power generation in Australia, there are less expensive and hazardous ways to attempt it than expanding nuclear power. Although nuclear energy does not produce air pollution, it is a danger to human health, damaging to the environment, exorbitantly expensive and extremely time-consuming, proving that it is not a suitable alternative to coal power for Australia.

Intergovernmental Panel on Climate Change (IPCC) highlighted in its 5th Assessment Report both the unequivocal warming and apparent human influence on the climate system. Anthropogenic (human-induced) climate change was proven by the increasing atmospheric concentration of the greenhouse gases, radiative forcing, and observation over warming and the climate system. It is also emphasized that to reduce changes in the climate system will require substantial and continuous reductions of greenhouse gas emissions (IPCC, 2014).

Global climate change is a topic that had been hotly debated across the country for years. Though not many people believe it, scientists have proved the global warming is in fact partly caused by man. The greenhouse effect is gradually increasing the temperature of the earth because humans are constantly burning natural gases and oils, greenhouse gases being trapped in the atmosphere, deforestation, and the lower-level atmosphere is expanding exponentially. These every day routines may not seem as if they are effecting anything, but in the end this change in the global climate could harm the lives of all people and living organisms.

According to the International Panel on Climate Change (IPCC) there is a scientific consensus that the earths climate id being affected by human activities. The IPCC 's conclusion is that most of the observed warming of the last 50 years is likely to have been due to the increase in greenhouse gas concentrations. (McCarthy 2001, p.21) . “Greenhouse gases are accumulating in Earth 's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise” (National Academy Press 2001, p. 1).

When the issue of global warming comes up in conversations, people usually groan and avoid conversation, and many roll up their sleeves and prepare for a heated debate. Some people feel culpable and concerned; others simply do not care. There exist many contrasting viewpoints which yield very distinctive stances on the subject. While many people may claim disregard on the issue, the media has broadcasted substantial data showing gradual rise in global temperature and the topic has been discussed in schools and seminars around the globe (Santhanam).While there may be developing countries that do not understand or recognize global warming or how humans contribute to it, developed countries are very educated about the situation yet, they are sadly the world’s largest contributors to global warming. The big question for everybody is will those who can act to preserve and maintain the planet do so, or will they remain careless and irresponsible as the world crumbles beneath their feet?

Global warming has been one of the most challenging problems our society has encountered and people don't acknowledge that our climate change is becoming worse as the time goes by. Climate change which is said to be the regular or ordinary weather in an environment consists of patterns like seasons and temperature. Climate patterns play such an important role in constructing an essential ecosystem, human economies and cultures that rely on them has raised the surface of the world's oceans in recent decades by melting glaciers and causing seawater to expand as it warms. In addition, thermal expansion from current and future greenhouse gas desolation and increasing mass losses from the glaciers and ice sheets due to warming oceans and

The IPCC define climate change as “change in the state of the climate that can be identified (e.g. using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer. It refers to any change in climate over time, whether due to natural variability or as a result of human activity” ( “Observed”). In today’s society, there are various opinions over whether humans are contributing to climate change or if natural causes are contributing to climate change. Some people believe that humans are the main contributor to climate change, whilst others believe that natural causes are playing a substantially bigger role in contributing to climate change. Both human and natural causes play a role in contributing to climate change.

Have you ever wondered why people tell you not to drink water when it is raining outside? Well the answer is simple pollution has affected our water source by ground and in air. This is rain is most likely to be in high population cities called acid rain. This acid rain not just harms people, but also harms animals and plants. According to British Broadcast Company (BBC), In Rio de Janeiro, Brazil, over 50 tons of dead fish were taken from the lagoon the scientist have figured that they fishes were deprived of oxygen because of a phenomenon called algae bloom which was caused by pollution of sewage during this period of time. Pollution is our worst enemy, but it is also a lesson that we can learned and conquered with our new technology and with the help of society.

Previously, climate change was believed to happen naturally. However, over the years, scientists have started to argue that anthropogenic factors are the main contributor. Scientists have also been more confident and forthright in informing the public that climate change is caused by human activities. The IPCC Fifth Assessment Report mentions that “human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history” (2013). In addition, most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic Green House Gas (GHG) concentrations (IPCC AR4 2007). In fact, there are many other anthropogenic impacts that cause climate change.

Global Warming is a long term increase in earth’s average surface temperature. Because global warming does not cause uniform warming in all locations and because many other changes in climate are occurring, scientists often prefer to speak of ‘’Global Climate Change’’ rather than of global warming when referring to the whole complex of climate changes caused by Human activities. Global climate changes, including episodes of global cooling and warming, have occurred many times throughout earth’s history as a result of natural variations in solar radiation, volcanic eruptions and other factors. The atmospheric concentration of greenhouse gases have increased because of human activities, primarily due to the combustion of fossil fuels, deforestation and agricultural practices.

The most authoritative and objective source of information on climate change (or global warming, as some prefer to use) is the Intergovernmental Panel on Climate Change (IPCC), a group that began researching climate change in 1992. The IPCC was launched by the United Nations Environment Programme (UNEP) and the World Meteorological Organizations (WMO) in order to "…provide an objective source of scientific information" (UN.org). It was clear by the middle of the 20th century, the UN explains, that as a "…side effect of the industrial age…human action had significantly increased the production of…carbon dioxide" one of the main greenhouse gases that contributes to global climate change.

This paper deciphers the risks and damages associated with global warming. All the hazards are discussed in detail along with living and nonliving factors that causes or are affected by global warming. Measures to attain sustainability are also discussed thoroughly. Benefits and challenges to attain sustainability are also argued.

For decades, scientists have been warning world governments about the threat that global warming poses to life on Earth. The scientists have raised the alarm numerous times, even as the effects become noticeable today. But why then, as the effects of global warming are becoming more obvious as time passes, have countries like the US, Australia, and Canada done nothing to address the problem? As Kiribati, the Solomon Islands, Fiji, and other pacific island nations sink due to rising seas perpetuated by global warming, these countries have been accelerating the demise of these small island nations by not only refusing to address the problem of climate change, but by throwing gasoline at the fire as they embrace dirtier sources of fossil fuels. The answer to why there’s inaction on global warming lies on the internal situation of these nations, which have similar things in common, such as concern that taking action to mitigate global warming would have devastating effects on their respective country’s economies, but most importantly, because of the lack of interest by the public to deal with the problem, which is only being worsened by a disinformation campaign being led by fossil fuels companies.

With the increasingly serious problem of global warming, Australia’s climate has warmed since 1950. ("State of the Climate 2014: Bureau of Meteorology", 2016) Compared with air conditioners which required for high cost, electricity expense and health hazard (under an enclosed environment, there has poor air circulation and air quality which would have negative effect for human body. Moreover, without appropriate maintenance, some particulate matter such as bacterial, pesticides and allergens can enter houses from outside environment which will cause health problems.) (McCarthy, Ludwig, Brown, Vaughn, & Roberts, 2013)

Human activities have been identified as the most significant cause of recent climate change; it is often referred to ‘Global Warming’. The main cause of global warming is emission of greenhouse gases .The main source of energy today - coal, gases and oil produce greenhouse gases, in particular carbon dioxide. Nuclear energy can reduce the dependence on fossil fuels. It is used to generate electric power but unlike fossil fuels it does not emit greenhouse gases. Therefore, the best possible solution to limit the emission of greenhouse gases and to control change in climate .The major reasons to challenge the above thesis are reliability and efficiency of nuclear power, low greenhouse gas emissions and low cost electricity production from nuclear energy.
