Global warming can be defined as the increase in average temperature of the Earth's near surface air and oceans in recent decades and its projected continuation. (Wikipedia, 2007) Global warming is closely correlated with the increase of greenhouse gases in the atmosphere. This increase in global temperature will eventually have extreme repercussions on the earth. Greenhouse gases are the gases, such as water vapor and carbon dioxide, in the atmosphere which hold heat, contributing to the greenhouse effect. Some greenhouse gases occur naturally, while others result from human activities such as the burning of fossil fuels. (Wikipedia, 2007) By man made means, these greenhouse gases have become excessive in our atmosphere. This will cause the earth to over heat, which will lead to problems that will lead to the end of the Northern Hemisphere.
With the increase of global warming, Earth can expect consequences such as flooding in costal areas due to melting glaciers causing the sea level to rise, an increase in storms, droughts and heat waves, changes in precipitation and even an...
