Air Pollution and Global Warming SCI 275 Cheryl Wilson September 30‚ 2012 Tori Robinson Air pollution causes global warming through the greenhouse effect‚ according to the United States Environmental Protection Agency. The greenhouse effect occurs when greenhouse gases trap and heat energy from the sun and prevent it from escaping Earth’s atmosphere and entering space.” (EPA‚ 2012) Atmospheric pollutions are caused by gasses and solid particulates released into the atmosphere. The most hazard atmospheric

Title: Global Warming Specific Purpose: To inform the audience about three issues of how global warming is affecting our weather‚ animals‚ and our future. Thesis: According to National Geographic Average temperatures have climbed 1.4 degrees Fahrenheit around the world since 1880 and by 2050‚ rising temperatures could send more than a million of Earth’s land-dwelling plants and animals down the road to extinction. Introduction I. Open with Impact: Is the climate warming? The impacts of global

Is global warming due to human actions? Introduction Global warming refers to the increase in the average temperature of both the earth’s near surface air and the oceans. The temperature increase began in mid twentieth century and is predicted to continue into the future. For example‚ during the last hundred years ending in 2005‚ the earth’s surface air temperature has increased drastically (Thomas‚ C. D‚ 2004). Basically‚ global warming is the recent increase in the average air and ocean

A notorious controversy surfacing nationwide consists of global warming. Chemistry plays a vital role in studying the chemicals involved in the greenhouse effect. It is critical for chemists to be informed about substances that contribute to climate change which subsequently allows them to take action. Statistics regarding the global warming theory remain an issue in that scientists disagree about the causes and effects. However‚ the Earth has indeed risen in temperature. Scientists supporting the

Global Warming: Causes‚ Effects‚ and Solutions. Global Warming is the rise in the average temperature of Earth ’s atmosphere and oceans since the late 19th century and its projected continuation. Many people do not see this as a problem. However‚ it is currently a huge issue that is often talked about among scientists and many other people. Global Warming is caused by many different things. Greenhouse gases‚ deforestation‚ and solar activity are three different proven facts that cause global warming

Introduction A. Attention Getter: Think of a world where more hurricanes and tropical storms causing massive destruction in different areas around the world and more animal species losing their habitats and becoming extinct just due to B. Relevance: The human activity of using too much of fossil fuel from mobile vehicles to the electric energy in outlets is affecting our planet C. Propositional Statement: Global Warming is still an ongoing problem‚ because it’s degrading of the world. I propose that

Global warming is a major issue in society. It has entered political speeches‚ agendas‚ pop culture‚ and sparks scientific debate. Global warming has been said to be responsible for heat waves‚ the rise of sea levels‚ flooding‚ drought‚ malnutrition‚ water pollution‚ and spread of disease. There is proof that the Earth’s temperature has risen‚ but is that really a threat? According to Jonathon Patz‚ with the John Hopkins Bloomberg School of Public Health‚ and Sari Kovats‚ with the London School

Global Warming: Causes‚ Effects and Solutions "’The future is here. Greenhouse warming is no longer just a possibility‚ it is happening now‚’ said Dr. Michael Oppenheimer‚ a senior scientist with the Environmental Defense Fund" ("Greenhouse Warning"). Representatives from more than 160 countries met together in the first ten days of December this year to come to an agreement on a treaty to slow down global warming by setting the limits on the countries’ greenhouse gases emissions‚ which include

Putting Global Warming on Ice What makes the earth’s temperature rise and fall? Do greenhouse gases block solar heat from leaving the earth‚ or is it only a product of solar activity? Many people have theorized on what causes temperatures to change. A catch phrase named Global Warming came to popularity. Environmentalists from all walks of life joined the ’global warming’ fight. According to Thomas O’Connell the global warming debate wasn’t accepted in the 60’s and 70’s when he studied it. It only

Global warming is the greatest challenge facing our planet. It is‚ in fact‚ the increase in the temperature of the earth’s neon- surface air. It is one of the most current and widely discussed factors. It has far-reaching impact on biodiversity and climatic conditions of the planet. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels‚ the melting of ice caps and significant worldwide climate changes. In short‚ global warming represents a fundamental
