Assignment Cause and Effect: Global Warming
Essay 3: Writing to Show Cause and Effect
USE THE TEMPLATE BELOW AS A GUIDE FOR THE ESSAY.. YOU CAN DEVIATE IF NECESSARY
Write an academic essay where you show a clear relationship between cause and effect, with a topic chosen from your major field of study, your work life, or your personal life. Here are some examples of topics from your textbook and from successful student papers:
• Causes of symptoms or conditions (medicine and health-autism, ADHD, cancer, sports injuries)
• Causes of student success or failure, effects of teaching methods or tools (online learning, adult learners, returning students, homeschooling)
• Causes of business growth and failure, marketing, business trends
• Causes and effects of climate change, ecological change, scientific phenomena
• (adapted from Russell 196)
You may have other ideas and are not sure how to use them in a cause and effect essay.
Feel free to ask about getting ideas to help shape your topic into a Cause and Effect framework.
• You will write your essay in the third person.
• Use the Online Library article databases, no open web sources.
• You need a minimum of three sources for your essay.
• Integrate the sources using MLA format.
• All essays should be 750-1000 words, in MLA format.

I. Introduction
II. Science Global Warming
A. Science shows that nearly 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapor, carbon dioxide (CO2), methane and ozone.
B. Greenhouse gases are those gases that contribute to the greenhouse effect. The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide.
C. When sunlight reaches Earth's surface some is absorbed and warms the earth and most of the rest is radiated back to the atmosphere at a longer wavelength than the sun light. Some of these longer wavelengths are absorbed by greenhouse gases in the atmosphere before they are lost to space. The absorption of this longwave radiant energy warms the atmosphere. These greenhouse gases act like a mirror and reflect to the Earth some of the heat energy which would otherwise be lost to space. The reflecting back of heat energy by the atmosphere is called the "greenhouse effect".
III. Causes of Global Warming
A. The reflecting back of heat energy by the atmosphere is called the "greenhouse effect". The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds)
B. Carbon dioxide CO2, which causes 9-26%
C. Methane, which causes 4-9%
D. Ozone, which causes 3-7%
E. Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons.
IV. Effects of Global Warming
F. Greenhouse gases in the atmosphere act like a mirror and reflect back to the Earth a part of the heat radiation, which would otherwise be lost to space.
G. The higher the concentration of greenhouse gases like carbon dioxide in the atmosphere, the more heat energy is being reflected back to the Earth.
H. The emission of carbon dioxide into the environment mainly from burning of fossil fuels (oil, gas, petrol, kerosene, etc.) has been increased dramatically over the past 50 years.
I. Rising sea levels, higher temperatures, droughts, and unpredictable weather patterns.
V. Solutions to Global Warming
J. Renewable energy sources such as wind and solar
K. Electric vehicles
L. CO2 capturing
Vl. Conclusion.
