FACT #2- Global Warming


1. http://www.livescience.com/globalwarming/

• LiveScience
• Scientists from the Intergovernmental Panal on Climate
• I think the source looks really credible.
• This site explainswhat global warming is. Scientists predict that by the year 2100, average global temperatures will increase 1.4 to 5.8 degrees.
• I do believe this source becuase, i feel that the world is really pollutioning the environment which may cause global warming.

2. http://earthobservatory.nasa.gov/Features/GlobalWarming/

• Earth Observatory
• Holli Riebeek
• this source is credible
• They are saying that global warming is happening right now. For over the the last century, cars and factories have spewed billions of tons of greenhouse gases into the atmosphere, and these gases caused temperatures to rise between 0.6°C and 0.9°C (1.08°F to 1.62°F).
• I do believe this because this is the second source in a row that has said the same thing.

3. http://globalwarmingdatabase.blogspot.com/

• Global Warming Articles Database
• no author
• i think this source is very credible
• many expect the new climate deal to be reached by the end of this year.
• I do not believe this site becuase, even though it is not the end of the year, i highly doubt that the temperature rate will be reached.

I do believe this fact! First, because this winter was hotter than all the other winters we've had for awhile. Second is because, forecasters are saying this summer is going to reach temperatures that will go on record.
