Global Warming Article: Step One

Step One:
Does the Wikipedia article appear to be biased in any way or does it maintain neutrality?

Bias is when a statement reflects partiality, preference, or prejudice for or against a person, object or idea. The Wikipedia article on Global Warming is biased toward the global warming. The language within the article appeals to emotion calling for man to take action.

• What facts has the author omitted?
The author of this article omits information about differing viewpoints. While there is a section called "Global warming controversy", it mainly addresses the fact that there is a controversy. It didn't give differing opinions and states that "No scientific body of national or international standing disagrees with this view, though a few organisations have non-committal positions."

• What additional information is necessary?
Additional information on the Earth's natural temperature cycle would be important. The article mainly focuses on temperatures since the Industrial age and the 20th Century. How long have temperature records been kept? Has the Earth experienced Global warming before?

• What words create positive or negative impressions?
"Warming of the climate system is unequivocal..." Unequivocal means definite, clear, leaving no doubt. Use of this word points to no other alternates. Other words and phrases used in the article to create a negative impression of global warming include: threat and dangerous anthrogenic. Additionally, I noticed that the article referred to "expert judgement". Who are these experts?

• What impression would I have if different words had been used?
Had a word other than "unequivocal" been used, global warming may not be considered of dire importance. Had the "experts" been named, more or less credability may have been given to their opnions and research.
