Global warming has increasingly become a popular topic in our society over the past couple of years. Many scientists are finding that recent years our planet is growing warmer. Global warming is described as the predictable continuation in the current increase of the temperature of the Earths Ocean and atmosphere. The interest that has generated from global warming is attributed to its effects and causative agents and factors. Scientific research that has been conducted over the years indicates that global warming is currently occurring and the human activities are the main initiators of the aspect (Boykoff,125). However, extreme weather conditions have been linked as initiators as well but the concentration is aimed at the human beings. The greenhouse effect has been one of the major concerns among the activities conducted by humans. The greenhouse gases have been detected to cause an imbalance in the atmosphere as they trap the heat emitted by the sun. However, as much as scientists have been trying to prove the existences and effects of global warming, and how it can be dangerous, there has been rising controversy which based on the results collected. The controversy is based on the arguments regarding the causes, nature and consequences. The arguments are generated by the fact that the evidence produced by the scientists working on the idea is not sufficient. Therefore, this paper aims to look at global warming and the controversy. Here is the significant question: Are the arguments presented by scientists sufficient to prove the existence, causes and consequences of global warming?
The first point is the causes of global warming. According to the scientists and professionals, human beings are the main initiators of global warming. This belief has been supported by the research which has been conducted reflecting on the human activities as one of the major concerns has centered on the greenhouse effect. This is in reflection of the gases that are emitted from the greenhouses leading to global warming. The greenhouse effect makes sure that the heat and light can have access through the atmosphere but it cannot get out. The green house gas causes a warming of about 33°C (Boykoff 126). The fact that most of the gases and water vapor further supports the warming effect that they have on the earth. After the industrial revolution, the amount of greenhouse gases in the atmosphere has been steadily increasing (Nordhaus and Boyer 26). However, despite the fact that there has been some evidence gathered to prove that the greenhouse gases have increased the temperature of the earth, some people still do not look at global warming as a threat as they do not believe in its existence.
The argument presented by the critics is based on the fact that the data collected is not clear enough to indicate that there is a measurable upward trend on global measures. Scientists have not been able to produce long term historical climate data, and this has made the data that they have collected over the years to be rendered not enough by the critics of the existence of global warming (Held and Soden 441). Some of the scientists, who do not believe in the existence of global warming claim that other scientists have collected data that is interpreted incorrectly since they want to prove that global warming is occurring, or they want people to believe in its existence. They claim that their judgment is clouded by the fact that they are worried about global warming. The statistics collected cannot be used to prove it, and they should focus on collecting evidence objectively.
Some of the scientists, who believe global warming is currently occurring, believe that it is nothing to be worried about. Therefore, the controversy is looked at based on different angles, where the causes are disputed as well as the consequences. The argument presented on the effect of the greenhouses is based on the importance of the greenhouses (Hughes 56). The belief is based on the fact that temperature can change in manner that will benefit us. For this reason, the greenhouse effect creates an appropriate atmosphere that helps in the sustenance of human life. The explanation used is that without the effect of the greenhouses, the earth would be freezing or too hot for people to survive (Hughes 56). Scientists, who believe in global warming, use this explanation provided to claim that the prolonged effect of the greenhouses, makes the earth unusually warmer and this has a negative effect on the lives of all living things (Held and Soden 445). The theory that has been developed is that with too much of the greenhouse gases in the atmosphere, the earth will trap too much heat and it will be too hot for any life to survive. Therefore, every living thing would die.
Although there has not been such an experience before, there have been some changes in the climate that can be used to support the claims of the scientists. The evidence presented by the scientists is based on the long term forecasting, but since they lack any historical evidence it has become difficult for them to prove their research (Boykoff 128). In addition, there have been global temperatures that have been linked to global warming, but the argument is based on the fact that they could be the natural occurring climate shifts of the earth or other factors other than the green houses.
The second point is the expected changes due to global warming. Scientists have not only been focusing their study on the existence of global warming, but they have also been focusing on the likely effects and the precautions that people need to take. Global warming has been detected in a number of systems that are used to monitor the temperature changes. There have been some cases of the rising sea levels and the receding ice caps in some of the mountains as well as snow quantity (Hughes 57). These changes are expected to influence a great warming over land. Other effects related to the atmosphere are: increase in levels of acidity, temperature rise, oxygen depletion and other related concepts that are related to warming of the earth.
The changes are not only based on the climate, but they are also based on the social factors as well, which revolve around the living things and how their environment and community, their surroundings in general, will be affected. The human societies are rather vulnerable to the extreme weather conditions than the climatic changes. The adverse effects of the climate changes have been evident on the small islands mainly (Held and Soden 448). This has affected human health in different ways. Malnutrition has been the leading effect on the health of the people because of the changes in climate. The unfavorable drought conditions have led to the dietary changes of the people affected and this has reduced the overall consumption (Boykoff 130). In general, this has led to micronutrients decencies, and in some extreme cases there have been reports of death due to starvation and lack of proper meals. The World Health Organization (WHO) got involved in the study as they had to research on the cases of mortality and morbidity due to a range of factors including climate change (Nordhaus and Boyer 34).
Some cases based on the climate changes were recorded as well, and the fact that was no measures taken to prepare for the changes was highly reflected on. Moreover, the research has been conducted on the suffering of the people based on the climate changes, and the results have indicated that the suffering was being caused by four reasons which are: heat waves, floods, droughts and storms among other factors (Hughes 59). These climatic conditions have additionally contributed to the spread of infectious diseases among the regions affected by these climatic conditions. These include three things which are malaria, diarrhea and dengue.
Migration and conflict are other effects of global warming triggered by the climatic conditions. They may not be considered as direct effects, but the circumstances leading to the migration are caused by the climatic changes. When the living conditions in one area become unbearable, the people are forced to migrate to better areas and this may arise in conflict as fight for space becomes the main issue.
The argument that is used to challenge these effects is based on the fact that these are natural climate shifts that are bound to happen from time to another time. The changes are quite unusual, but they cannot be used to explain global warming. These changes have already begun occurring in some particular areas, and the scientists believe that they are not to be highly worried about (Held and Soden 450). Their belief is based on the ability of the earth to withstand these climate changes than what people tend to think. The earth can be able to survive these changes and so will the plants and animals as they will have to adapt to the climatic changes. In response to these effects that the climate changes are having on the social lives of the living things, scientists claim that people and animals can be able to adapt to the adverse living conditions. Their stand is still based on the fact that nothing catastrophic will occur as a result of the global warming (Boykoff 135). If the greenhouses projects are stopped in most of the countries, then the economic damage will be more than the climatic changes which are likely to occur. However, the results collected on the effects have been providing different answers so far.
There have been increased cases of deaths and cases of malnutrition as well. There is no doubt that they have been caused by the climatic changes. The relationship between the climatic changes and global warming is very strong despite the fact that most people do not want to believe it (Root et al 58). Some of the scientists, who are against the existence of global warming, claim that technology can be used to deliver the world from any mess and its constant evolution are the hope that the world has if global warming undoubtedly does exist (Hughes 59). However, the same cannot be claimed for the people suffering from the adverse effects of the changes in the climate. Therefore, the lack of acceptance of the existence of global warming is causing other people their lives as they cannot be able to take any preventive or protective measures prior to the disaster (Held and Soden 451). This is because the decision lies within the government, and they have to weigh their economic options as well before they make any drastic decisions.
The last point is the public opinion. There has been the growing belief among the members of the public, despite the dispute among the scientists on the existence of global warming and its effects. The change in attitude is a recent factor because of the media. The media is being a key factor in communication provided very minimal coverage on global warming and its effect (Weart 55). The situation was still the same in 1988, as most governments were not convinced of its existence as they could not attribute the hot weather, they were experiencing to global warming (Held and Soden 468). However, based on the environmental changes that have been taking place and the effect they have on the social lives of the people, the attitude has changed significantly. The people lacked the knowledge that they needed to understand global warming and the fact that the media was not providing any coverage on the issue placed them in the dark (Victor 46).
Most of the environmental organizations and activists were intent on supporting global warming and its effects. Their actions got them the attention that they needed, and this also raised an interest in the media department as well. This has caused significant changes among people and governments (Held and Soden 454). This was evident in that all of the European Union member states and European countries have already taken an action to reduce the green houses operations in the country. This is the first step in controlling the situation as the climate changes are caused by the gases emitted by the projects. This is not the only causative agent but the control of the green houses will solve a major part of the problem.
Europe is rated as the top nation in taking effective measures in controlling the climatic changes is the second most serious problem that is facing the universe currently. Based on the evolution of the industries and technologies, controlling the green houses will be difficult but the fact that they are trying provides the people with hope for a better future (Hughes 60). The media has been playing an active role in supporting the existence and effects of global warming and forcing most of the governments to take action that will prevent it. However, there are still ongoing arguments that the media should be able to cover both sides of the controversy (Held and Soden 461). Despite, the ongoing debates, the fact that the people are craving more knowledge is the objective that most scientists have been trying to achieve. The number of people in the public that believe in global warming is increasing on a daily basis. Although some countries are still reluctant to control their green houses as they are still waiting for more proof, there has been significant change in the public in general. The belief of the existence of global warming is stronger than the belief that human activities are causing it. However, this is not a problem because the fact that there is action being taken is what is important.
In conclusion, global warming has been a controversial issue for a long time now, but there have also been some changes in the department. The argument that was against the existence of global warming and its effects has gradually changed as there are many different opinions now. This is attributed to the climatic changes that have been taking place, and how they are affecting the people. Therefore, although it has taken time scientists have been able to provide solid arguments that have changed the opinion of people and supported the existence of global warming. People may or may not believe the scientists. It is still reasonable for them to do whatever they can to stop this process.
