Credibility: It is very credible because our school and many other schools use this as a resource site.
What It Says About the Fact: The source says that the climate is warming because of the greenhouse effect. The levels of built of heat gases are increasing which causes the natural cycle to be off balance. As the gases build up, temperature is rising all around the world.
Do I Believe the Source: Yes I do believe it.
Why or Why Not?: I believe it because this website was designed to have only the correct information for students because we use it as a research site. If this is not true then all the creators of this website who are doctors with degrees are wrong. So I do believe this source.

Credentials: It doesn't have any but I'm pretty sure that the people who wrote this article are all specialists in this field.
Credibility: It is very credible because the website has .gov at the end and people can't fake a .gov because a .gov makes it an accurate website.
What It Says About the Fact: It says that the CO2 traps the infrared rays and keeps the Earth warm but there has been so much CO2 that the infrared rays are warming the Earth.

Credibility: It is very credible because this website was most likely written by teachers because it has a .edu.
What It Says About the Fact: It says that CO2 contributes the most to global warming and because humans are using so much CO2 , global warming is happening.
Do I Believe the Source: I do.
Why or Why Not?: I believe this website because it seems very accurate. It has graphs that was posted by Phil Jones who is a researcher in Climatic Research Unit, UK. This website also won an award and it also has the .edu which means it is an educational website.


Believing: I really believe this website because all three of the websites I have found are all very offical and the fact that I was researching on was in these websites and they have stated in each website that the increasing CO2 is causing global warming which is a tempertaure increase around the world in certain areas and a temperture decreases in other parts of the world.
