Global Warming: How Does it Really Happen?
Thank you everyone for attending today. My name is John Smith and I am majoring in Environmental Science at the Harvard. The University has asked me to conduct a presentation on global warming and the effects on the planet. Combining the knowledge gained through coursework and the research I have conducted, I will be presenting you with information on global warming and how global warming has been affecting the Earth well before humans could make an impact.
Lets look at what global warming actually is. A definition of global warming pulled from dictionary.com defines global warming as, “an increase in the earth 's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect” (Dictionary.com). Looking at the definition of global warming many may ask, well what is the greenhouse effect? The green house effect is,
An atmospheric heating phenomenon, caused by short-wave solar radiation being readily transmitted inward through the earth 's atmosphere but longer-wavelength heat radiation less readily transmitted outward, owing to its absorption by atmospheric carbon dioxide, water vapor, methane, and other gases; thus, the rising level of carbon dioxide is viewed with concern (Dictionary.com).
After looking at that long and complex definition of greenhouse effect to try and understand global warming a little better, many of you are probably puzzled. To help you, here is a much simpler definition that you don’t need to be a scientist to understand; “Global warming is a significant increase in the Earth 's climatic temperature over a relatively short period of time as a result of the activities of humans (Strickland, and Grabianowski). In this definition a relatively short period of time means, “an increase of 1 or more Celsius degrees in a period of one hundred to two hundred years would be considered global warming” (Strickland,
