Global warming is an average increase in the earth’s overall temperature. Increased temperatures affect climate and human dependence on earth’s resources. The enormous increase in greenhouse gasses (GHGs) since the 
beginning of the industrial age is believed to be the causation of increasing global warming at an alarming rate. Without a global effort to quickly reverse the trend, the potential for food shortages, wars over water, and displaced habitats in this century is very possible.
