Global warming Essays (1071 words) - Climate Change, Global Warming Aim To investigate how humans are contributing to climate change, the effect of this on social, environmental and political situations around the world and how organisations are trying to better manage the situation. Global warming Global warming is the term used to describe a gradual increase in the average temperature of the Earths atmosphere and its oceans, a change that is believed to be permanently changing the Earths climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming. The earth gets heat from the sun. As Carbon dioxide is a greenhouse gas, traps this heat and keeps it from escaping back to outer space. Due to burning fusil fuel such as oil, gas and coal people all around the world are adding extra carbon dioxide to the atmosphere. Thus this extra carbon dioxide is emitted in the atmosphere, the heat energy from the sun will be strongly insulated with the carbon dioxide - causing the Earth's surface to become much warmer hence "global warming." The polluting carbon dioxide can make Earth's climates warmer. http://images.theage.com.au/2014/11/02/5946209/1103GlobalCarbonEmissions3.jpg Social consequence of climate change India - 2009 There are some social consequences of climate change .Climate change will act as a multiplier of existing threats to food security: It will make natural disasters more frequent and intense, land and water more scarce and difficult to access, and increases in productivity even harder to achieve. The implications for people who are poor and already food insecure and malnourished are immense. The existing inequities in food security, food safety and nutrition are likely to be further widened by the adverse consequences of climate change. Adapting food production systems has the potential to significantly increase the resilience of poor farmers to changing climate conditions. However, the vast majority of the 1 billion undernourished people do not have sufficient capacities and resources in order to adapt to or cope with the risks posed by climate change. Loss of food, water or even job makes people to move from their place or even their country. Environmental consequence of climate change Climate change is already having an impact on biodiversity, and is projected to become a progressively more significant threat in the coming decades. Loss of Arctic sea ice threatens biodiversity across an entire biome and beyond. The related pressure of ocean acidification, resulting from higher concentrations of carbon dioxide in the atmosphere, is also already being observed. Ecosystems are already showing negative impacts under current a level of climate change which is modest compared to future projected changes. In addition to warming temperatures, more frequent extreme weather events and changing patterns of rainfall and drought can be expected to have significant impacts on biodiversity. For instance in South America, Sea turtles lay their eggs on Brazilian beaches, many of which are threatened by rising sea levels. Climate change also threatens the offspring of sea turtles, as nest temperature strongly determines the sex: the coldest sites produce male offspring, while the warmer sites produce female offspring. This nest-warming trend is reducing the number of male offspring and seriously threatens turtle populations. Political consequence of climate change There are some political consequences of climate change. At the centre of the governments policy on climate change is pricing carbon. Many commentators and politicians have referred to this as a carbon tax. The idea is that polluters will pay per tonne of carbon they release into the atmosphere. This cost will initially be set at $23, and increase gradually until 2015, when we will shift to a trading scheme that will let the market set the cost. This is widely thought of as the most effective and least costly mechanism to reduce carbon output and reduce the level of climate change that is occurring. There is a question that people often ask why should Australia act to reduce their carbon pollution when other countries are not. The reality is that many other countries have already made huge steps towards reducing their carbon output, and that includes developing nations like China. Countries have started this transformation to take advantage of the economic opportunities stemming from the next stage of global development that will be powered by clean energy. Nowadays we are starting to see the
