Do I Believe What I Read?

After reading the two articles about global warming, I came to the conculution that I did not believe or agree with either of the two.  Actually saying that I did not agree would be a false statement because I could agree with both.  National Geographic, I personally think, is not a bias website.  On the other hand, I could not decipher whether or not the other one was bias or not.  I don't think that they both gave all the information and I think any information they had was accurate for the entire globe.
