• http://scienceline.org/2009/04/06/environment-bond-sea-level-rise-north-america/
• The source is Scienceline.
• The source credentials include Jerry X. Mitrovica, a geophysicist at the University of Toronto in Canada.
• The source is very credible because Jerry X. Mitrovica is the lead author of the predictive study.
• The source says that the ocean bordering North American coastal cities like New York, Washington, D.C. and Los Angeles may rise by more than 20 feet if the West Antarctic ice sheet melts due to global warming.
• Yes
• I believe the source because Mitrovica is the lead author of the predictive study of global warming and is one of the most credible sources out there.

• http://news.mongabay.com/2006/0323-sea_levels.html
• The source is Mongabay
• The source credentials include researchers from the U.S. National Center for Atmospheric Research (NCAR), the University of Arizona, the University of Colorado, and the University of Calgary.
• The source is very credible because it has multiple researchers that reply on this topic from many different well known universities.
• The source says "unless something is done to dramatically reduce human emissions of greenhouse gas pollution," said Peck "we're committed to four-to-six meters (13 to 20 feet) of sea level rise in the future."
• Yes
• I believe the source because it has a lot of research backing up the information and good data that supports it as well.

• http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2006/03/24/MNG22HTITV1.DTL
• The source is SFGate.
• The source credentials include many scientists one in particular is John R. Christy, a noted atmospheric scientist at the University of Alabama.
• The source is very credible because it has scientist from universities that study this subject and have accurate information on it.
• The source says that Glaciers and ice sheets on opposite ends of the Earth are melting faster than previously thought and could cause sea levels around the world to rise as much as three feet by the end of this century and 13 to 20 feet in coming centuries.
• Yes
• I believe the source because the information provided is written by top scientists and have facts and models in the article that back up the reason why they believe this.

4. I believe that Global sea levels could rise by more than 20 feet if global warming continues because of the rate of greenhouse gases being produced in the atmosphere and as a result icecaps are melting which cause an overall rise in the sea levels.
