The issues are: whether global warming is actually occurring, what are the causes of global warming and how it is affecting our world. Lastly, what types of actions should be taken. Some people would call it a hoax, but there are several people who truly believe this is happening and actions need to be quickly taken. The two terms, climate change, and global warming are interchangeable. However, some people will say they have two completely different meanings. Both of these terms follow one from the other. According to the U.S Environmental Protection Agency, global warming is defined as: “An average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere, which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes, both natural and human induced. In common usage, “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities.” While climate change is more local, it measures the effects of the continual warming trend by temperature, rainfall, snow and wind patterns over the past decades. This paper will be viewed from a public health professional standpoint on the effects of global warming such as actions that should be taken towards prevention, and ways to inform and communicate to the public on this subject matter. The author will also canvass, Communication for Persuasion Theory, Cultivation Theory of Mass Media, Mass Community Theory, and how they apply in getting the message out regarding global warming. 3 Chapter 2 The Concern Global warming resulting into climate change has numerous impacts in our communities such as water resources, forests, agriculture, coastal areas, and wildlife. Additionally, major health effects regarding humans. The concern with global warming is our planet is slowly increasing in temperature. The Intergovernmental Panel on Climate Change (IPCC) estimates that our earth has warmed 1.2 to 1.4 degrees over the past century and projects a further 3 to 7 degrees over the 21st century (EPA, 2009). This is causing several noticeable environmental problems within the earth. The (NRDC) Natural Resources Defense Council (2005) lists some of these particular issues in brief detail: Melting glaciers, early snowmelt and severe droughts will cause more dramatic water shortages in the American West. Rising sea levels will lead to coastal flooding on the Eastern seaboard, in Florida, and in other areas, such as the Gulf of Mexico. Warmer sea surface temperatures will fuel more intense hurricanes in the southeastern Atlantic and Gulf coasts. Forests, farms and cities will face troublesome new pests and more mosquito-borne diseases. Disruption of habitats such as coral reefs and alpine meadows could drive many plant and animal species to extinction. It has been known that the greatest concern is human-caused impacts towards the climate. The growth of the human population is constantly increasing. People are continuously burning fossil fuels such as oil, gas, and coal, which release a tremendous amount of greenhouse gas, subsequently trapping more heat near the earth’s surface. The greenhouse effect is a natural occurrence that helps regulate the temperature of our planet (EPA, 2009). The greenhouse gas emissions cause the warming trend are likely to continue into the future. The levels of these gases are increasing at faster rates then at any time in history. New technology, alternative energy sources, and carbon markets have been developed to help reduce 4 greenhouse gas emissions. However, among these developments it does not quickly solve the issue at state here. It is very important to be educated regarding science behind global warming, politics, and lifestyle choices, which influence trend in reducing emissions in the future. 5 Chapter 3 Actions to be pursued There are several ways to minimize emissions contributing to global warming. It is as simple as using energy-efficient products within a home. Energy-efficient products classified as Energy Star are becoming more popular without sacrificing features or functionality. Though it may be an investment upfront, an individual and/or family will save money in the long run. Energy Star is a government-backed program helping businesses and individuals protect the environment through superior energy efficiency. Appliances such as refrigerators, freezers, furnaces, air conditioners and water heaters utilize a great deal of energy. According to the Union of Concerned Scientists (2012) “If each household in the United States replaced its existing appliances with the most efficient models available, we would save $15 billion in energy costs and eliminate 175 million tons of heattrapping gases.” Exchanging light bulbs with energy-saving light bulbs such as compact fluorescents will tremendously decrease heat-trapping pollution and increase savings on electric bills. “If every household in the United States replaced one regular light bulb with an energy-saving model, we could reduce global warming pollution by more than 90 billion pounds over the life of the bulbs; the same as taking 6.3 million cars off the road” notes Union of Concerned Scientists (2012). The Union of Concerned Scientists (2012) mentions, “Each gallon of gas utilized is responsible for 25 pounds of heat-trapping gases in the atmosphere.” Based on a full 20-gallon tank, that is approximately 500 pounds of gases being emitted per vehicle. This is why carpooling, walking, riding a bicycle, or public transportation are highly encouraged in 6 communities because they are much more friendly towards the environment. Electric vehicles are in production; electric cars provide a clean and safe alternative to internal combustion engines. There are many pros and cons regarding electric cars. Electric vehicles are known for faster acceleration but shorter-range distance. They produce no exhaust but require long charging time. When it comes to purchasing a vehicle, it is wise to look into a variety of vehicles. To name a few, Honda Civic Hybrid, Toyota Prius, and the Kia Soul are extremely great on gas mileage and will greatly cut down on contributing to global warming. Another economical alternative is to expand the amount of plants and trees. Plants and trees absorb CO2 as they grow carbon naturally, which then increases the amount of gases we take out of the atmosphere. According to the Arbor Day Foundation, planting not only benefits the climate, but also provide cooling shade, block cold winter winds, attract birds and wildlife, purify our air, prevent soil erosion, clean our water, and add grace and beauty to homes and communities. If each person in the world was to partake in one or several of these actions listed above, it would drastically cut down on the amount of emissions humans contribute towards global warming. Each step would create a healthier world, as well as slow down the global warming process. 7 Chapter 4 Communicating to the public Health communication is crucial to the field of public health in effecting behavior change. The most important concept is to deliver the message to the public. There are several effective tools for distribution of information such as: pamphlets, brochures, newsletters, webpages, social networking, media, news stations, newspapers, flyers, radio stations and mobile devices. The utmost essential is to ensure wide distribution to the public. From a public health professional’s perspective, the target audience would be anyone who has a home or business and utilizes electricity. It would be sensible to send emails, flyers, brochures, pamphlets or new letters to local organizations, businesses, homes, schools as well as public health facilities to guarantee information is being widely distributed across the community. For educational purposes, professional speakers can go out to schools and present knowledge and information on global warming. Some individuals and/or families within communities who may be considered lowincome may not have access to numerous forms of technology. Broadcasting the message in other forms such as delivering newspapers, pamphlets and distribution of flyers. While global warming is a universal issue, it would be appropriate to reach out to communities across the United States, as well as other countries if possible. Reaching out to community centers, as well as local and state officials would be useful into connecting with higher organizations such as the World Health Organization and Environmental Protection Agency whom are extremely experienced. A majority of people benefit greatly from a visual perspective when referring to behavior change such as, attitudes, motivation and people's beliefs about their capabilities. For this reason 8 being, the author believes it would be wise to utilize several types of visual resources. People then become informed on how to assist the community as well as our nation, by partaking in simple habits to cut down on the use of energy. Good communication can rally support, calm a nervous public, provide much needed information, encourage cooperative behaviors and help save lives. Poor communication can fan emotions, disrupt economies and undermine confidence (WHO, 2005). Good communication also consists of accurate, honest, credible and appropriate information. Without these features it could lead to inaccurate and misunderstood information and responses. Incorporating facts, statistics and pictures is also beneficial to receive the visual perspective. Another factor would be to seek feedback on how well the message was delivered from which source the person had read or heard. Be willing to be open for suggestions as well as criticism and pay attention to your audience. Though the topic of global warming is a concern to people, it has been relevant for several decades and will continue throughout the future. The author believes that global warming would not be considered an emergency action message compared to an emergency, such as, an outbreak of a new unheard disease or main water source contaminatation in a community. However, it would be necessary to send out periodic public messages and information so people are reminded and are up-to-date. 9 Chapter 5 Theories The first theory regarding communication is the Communication for Persuasion Theory. Persuasion is a process by which people use messages to influence others. McGaan (2010) believes there are terms for persuasion, they list: Belief, value, motive, attitude, and behavior. By incorporating each of these terms into a message it can help persuaders analyze the situation and effectively create the message. Next is the Cultivation Theory, which was developed by George Gerbner, a professor of the University of Pennsylvania in the 1970’s. According to Shrum & Bischak (2001) “The Cultivation theory is based on the premise that both the ubiquity and consistency of television portrayals in American society have made it the primary source of information about the social world.” Though this theory can have negative and positive impacts on how people comprehend information, in this case regarding global warming, it would be positive. Viewers would benefit from watching programs such as National Geographic and the Discovery Channel, as well the local and national news. These stations are reliable and very informational which would aid in carrying the message out. The final theory is the Mass Communication Theory. The concept is, “when a source, typically an organization, employs a technology as a medium to communicate with a large audience” (Baran & Davis, 2010). Large, well-known organizations such as World Health Organization (WHO) or Center for Disease Control and Prevention (CDC) are more likely to grab the attention of viewers due to their quality and reliable material. An example of applying mass communication would be the WHO using newsletters, flyers, or webpages to reach out to a 10 large population on the topic of global warming. Once these types of organizations receive information, they have the necessary tools and proper technology to successful deliver messages. 11 Chapter 6 Summary In conclusion, global warming and climate change are certainly affecting our world as well as all the way down to us individuals. The world can truly benefit from people partaking in many actions to prevent furthering global warming from occurring. Worthy, effective communication is what can truly deliver a message towards the audience and will likely result in the message being heard and understood. What would the viewer what to hear and see? Will the information truly benefit them? The more you pay attention to your audience, the more chance you have of getting them to hear the message you want. Recommendation The author of this paper recommends recognizing the resources that are available. Though technology has and will always keep expanding, people should not only rely on new developments to cut down on energy, humans have become a major contribution towards global warming. There are several ways to reduce energy usage such as: using energy-saving light bulbs, purchasing Energy Star appliances, carpooling or taking other ways of transportation. Inn addition, tree and plants are a great benefit towards the community and atmosphere. When communicating a message on global warming to the public, it is key to emphasis the habits people can develop and continue through out their lives. If every household were to gain one positive habit to reduce emission, it would significantly decrease the amount of pounds we release to the atmosphere, which in turn will make it a much safer and healthier world to live in. 12 References Baran, J.S., & Davis, K.D.
