Reference books can be really useful for doing background reading on a subject. Most subject encyclopedia articles have bibliographies at the end for further reading, including journal articles. Reference books are also a good place to find facts, statistics, etc. Be sure to look in the index, usually located at the end of the last volume.

Here are some Library Subject Headings that may be helpful:
If your research is going to take you into more specialized areas, I recommend going to OneSearch Advanced Search,
and selecting from among the categories and subcategories. The categories most likely to be useful for your topics are Environmental Studies, and possibly Biology -- subcategory: Ecology and Evolution. The Physics category may also be useful.
A very good, interdisciplinary science journal article database, that covers mostly peer-reviewed journals is
In addition to being able to search by topical keywords, author, etc., Web of Science has the special feature of showing you who has cited an article, and how many times it has been cited. This is useful in a couple of ways: it can lead you to more recent articles on the same topic, and it gives an indication of how influential an article or author has been on other researchers.Academic Search Premier is good for its mix of scholarly and popular articles. Here you can find easier to read articles in magazines such as Scientific American and New Scientist, as well as news articles.
See the following library guide for getting the most out of web searching:
and the sites below for how to evaluate sources for reliability.
Start with this excellent web page "Critical Evaluation of Information Sources", created by UO librarian Ted Smith. It can be applied to both printed sources (books, articles) and web sites.
You can make certain assumptions about the credibility and reliability of information based on the publication. The most reliable sources are those which are considered "scholarly" and are usually peer-reviewed. How do you know if a periodical is scholarly?
The Good, the Bad, & the Ugly, Or, Why it's a Good Idea to Evaluate Web Sources
"Peer reviewed" is often used interchangeably with "refereed" (See "Refereed", below.) Peer review is the process of review by qualified outsiders known as "peers": that is, they are experts in the same field, who identify manuscripts, proposals, grants and other works that worthy of publication. In the peer review process, authors submit their work to scholarly (including scientific) academic journals, who in turn, send manuscripts an editorial board or similar group of peers to determine the article's acceptability, validity, reproducibility of results, grammar and scholarly use of theory. Authors may then be asked to edit or revise before their work is accepted for publication.
