Climate Change link - It's a good article. It does seem neutral, because it talks about climate change in general, not specifically anthropogenic global warming. However, those who deny athropogenic global warming may find it biased. Several statements had two references citing the same sentence, which shows that it is well supported with literature. It went through causes of climate change and the ways we know the climate is changing. It seemed like a balanced article. However, there was no mention of any deniers of climate change, their reasoning, or even mention of the controversy. It's probably a semi-protected article for this reason. A lot of people deny it and their claims are pretty baseless, they would definitely try to get on the cite and delete or deny many of the facts that are supported.

A.W. Kuchler - This is very sparse article. I could add information about his education, or general details of his life. Since there is only two or so sentences, there isn't much editing I can really do.
