It is clear that the Earth's average surface temperature is increasing. The rate of increase has accelerated over the past 100 years and scientists predict the increase will continue to rise. This may very well mean a rise in sea levels and other weather related events ( such as droughts, the extinction of plants and animals and severe storms). Many disagree on the causes of this warming. Some believe it is a natural phenomenon while others believe it is caused by human activity. The temperature increase, scientists believe, is caused by a process called the greenhouse effect--heat trapping gasses ( especially carbon dioxide) trap the sun's heat in the Earth's atmosphere ( much like the planet Venus). Excessive heat, needless to say, would impact all life on Earth and unless curtailed either naturally or by human intervention, would have dire consequences for our home planet.

go to the Library Catalog ( www.pccc.edu/library ) Be sure to restrict your search to PCCC. You will need your PCCC ID to check out books. If you pick an electronic book, ask the librarian for the ID and password if you are off campus, or find it in Blackboard.
