Credentials: A senior editor of Discover, a staff writer for the Los Angeles Times, and a senior writer at Science Digest. Mr. Revkin has a biology degree from Brown and a Master's degree in journalism from Columbia. He has taught environmental reporting as an adjunct professor at Columbia's Graduate School of Journalism.
Credibility: It is very credible because Mr. Revkin has a degree in biology and he also has a Master's degree in journalism which means that the information that he writes about is very accurate because he is a specialist in this field.
What It Says About the Fact: "the prospect that global warming from emissions of greenhouse gases would continue to erode the sheath of Arctic sea ice that the half-ton bears roam in pursuit of seals....The animals are resilient, eating walrus, grasses and even snow goose eggs when they cannot hunt their preferred prey, bearded and ringed seals....last year the United States Interior Department granted the bears threatened status under the Endangered Species Act."Do I Believe the Source: I do believe this source.
Why or Why Not?: I do believe this because the author has a degree in biology and he is also a journalist. This article would not be published if it were not true because it is published under the New York Times. This article also has quoted a doctor saying some of these things about polar bears being affected by global warming.

What It Says About the Fact: "Concluding that it is "highly likely" that mankind is to blame for climate change, it talks of more droughts, torrential rains, shrinking Arctic ice and glaciers, and rising sea levels for the next century...studies of polar bears have revealed that not only have their numbers declined by nearly one quarter in just 20 years to around 25,000 but so has their physique...but the scientists have observed that in the struggle for survival, the bears - and females especially - are now much thinner...scientists believe that four bears which recently drowned off the coast of Alaska had simply been unable to cope with a violent storm."Do I Believe the Source: I do believe this source.
Why or Why Not: I do believe this source, because it has a lot of information that are similar to the other websites I have found. It also has a picture showing what is happening, this source also quotes a doctor.
