Critical Overview of the Climate Change for Global Warming

Question: Discuss about theCritical Overview of the Climate Change for Global Warming. Answer: Introduction The aim of this paper is to discuss the issue of global warming as examined by Davidson. It documents and expounds the aspects of the factors that contribute to the factors that propel and exacerbate climate change, an assessment of climate change on our everyday lives and the planet and finally a range of recommendations that would be helpful in mitigating climate change. Causes of climate change Climate change is a burning issue and demands immediate attention. The temperature of Earth is contingent on the equipoise between entering and exiting the system of Earth. The energy from the sun known as the incoming energy keeps the surface of the Earth warm. Earth avoids warming when the energy from the sun is reflected back into the space. The Earth cools when the absorbed energy is liberated back into the space. Scientists have found that there has been a variation in the climate for a long time range (Redshaw et al., 2013). Climate change is also triggered. During the epoch of industrliazation, climate change was attributed to mostly natural factors like volcanic eruptions, solar energy and green house emissions. The Green House gases comprise of carbon dioxide (CO2), methane (CH4) and water vapour (H2O). The problem with greenhouse is that it makes the Earth warmer that the usual temperature of the Earth which is commonly known as the greenhouse effect. The composition of gre enhouse has severe implications on the environment. The absorption of carbon dioxide and its liberation is part of the natural carbon cycle through the respiration of animals and plants (Aldy Pizer, 2015). Apart from this, the plethora of human activities like combusting the fossil fuels and the transformations in the usage of land also liberate a wide amount of carbon dioxide into the atmosphere. It has been found that there has been an increase for carbon dioxide in the atmosphere. Another cause that triggers the presence of carbon dioxide is the volcanic eruption. It is estimated that the multifarious activities of human beings is responsible for the presence of over 30 billion tons of CO2 (Anderson, Hawkins Jones, 2016). Impact of climate change on our lives and the planet Davidson is of the view that scientists have not reached a consensus regarding the temperature sensitivity of the soil. The drastic change in the climate can pose pernicious health risks to the future generation as has been envisaged by the environmentalists and moral philosophers. One less discussed aspect of the change in climate is damage to properties. Pollution of the global atmosphere would portend to be damaging anything for the future generations (Davidson Janssens, 2006). Davidson believes that the present generation has the responsibility of not encroaching on the resources of the future generation. The environmental factors due to global warming is the melting of ice like the glaciers, mountains, ice sheets stretching over Greenland and West Antarctica and also the ice sheets on the Arctic sea. There has been a rise in the sea level due to the melting of icebergs and ice sheets. There has been a complete metamorphosis in the climatic conditions an increase in precipitatio n on the global level. The rise in global temperature has been detrimental for important species of fauna whereas beneficial for invasive species. For example, there has been a decline of Adelie penguins in the Antarctic region-their numbers have fallen from 32,000 to 11,000 over the last decade (Constable et al., 2014). On the other hand, there has been a proliferation in the growth of spruce bark beetles in Alaska that are known for consuming up spruce trees. It is predicted that there will an increase in natural disasters due to the effects of climate change. For example, floods, droughts, storms and hurricanes will become stronger if climate change is not mitigated. There is the prognosis that there will be a spread of malaria and the revival of the Zika virus (Global Climate Change, 2018. )Since there will be an alteration in the ecosystems, species that would not be able to migrate to compatible regions as a response to the climate change will extinct. Our power to combat climate change Human beings have the agency and the power to act sensibly to climate change. There needs to be a change in orientation in our everyday interaction with the environment. The first step is to subscribe to environment-friendly vehicles that would save and conserve energy. Cycling and walking can be a small step but it can go a long way in this initiative. In 2013, it was estimated that 44 per cent of the electric generation is an outcome of the renewable (Change, 2014). One can opt for battery chargers that can save $100 million of electricity bill and at the same time prevent the rise in greenhouse gases into the atmosphere. Human beings should ensure that their activities have minimal effect on the environment. The use of low-carbon sinks is one such step. People can use renewable power alternatives generated from the natural energy. Improper method of garbage disposal in the landfills will trigger the production of methane gas (Greaver et al., 2016). Therefore, human beings need to judiciously dispose their waste may be through the composting of kitchen scraps or through garden trimmings. Travelling via air has pernicious effects on the environment and therefore, it is sensible to cut down on air travel. There is also a need to change the consumption pattern whether in terms of automobiles or food. Purchasing products in bulk amount can be useful in lowering the amount on plastic wrapping or other associated packaging materials. Conclusion The factors contributing to climate change is the concentration of greenhouse gases in the atmosphere. Carbon dioxide is one of the most important reason for the rise in global temperature and so as methane gas. The drastic change in climate poses threat to the destruction of various species on the planet. In the Antarctic and Greenland regions, there has been a massive melting of ice sheets and icebergs that will rise the sea level. The need of the hour is to adopt a sustainable lifestyle and reduce the adversities of climate change and will be beneficial for the future generations. References Aldy, J. E., Pizer, W. A. (2015).
