Well written and informative, presents the facts in an unbiased way. While there was a good use of sources, it might benefit the story to add some additional sources who could provide a different perspective
This story gives a lot of background information to support the arguments made. Although more than one side of the story is conveyed, the author comes off biased which discredits the story and leads me to choose not to recommend it to other readers.
This article uses Barack Obama's visit as a ploy to gain additional readers. There is not much relevance to Obama's visit with the discussion of illegal immigrants. Also the anecdote about the car accident portrays immigrants in a bad light for most of the article before it is revealed that the accident was not the immigrant driver's fault.
This article has a lot of supporting facts for both sides of the global warming argument. There are relevant articles linked which adds more depth to the article as well as increases the reliability of the information in the article. It was easy to come away with an informed opinion of the issue without feeling as though one side of the issue was pushed without reason.
I think this is a good article but I personally have not followed this story and while there was some background information, I would like to have seen a little bit more as well as some citations or sources.
