EXERCISE 1 -- WEB RESEARCH (Annotated Bibliography)
(Due Tuesday Sept. 22)
Today we're learning about resources for studying Global Change on the web. In this exercise, I'd like you to try your hand at finding and evaluating information on specific topics on the web. There is a huge amount of scientific material published on a range of topics related to global change on the web. I'd like you to pick one topic, perhaps one of the following suggested topics, and search for six web sites that give you specific information on your chosen topic. Then, for each web site, you should describe and evaluate what is available. Please critique each page, using guidelines as we discussed in class. Check out the Library site on Evaluating Information. Be sure to cite the web site using proper web page referencing form. (All Geog courses are asked to use APA citation style.)You may use the Web Links page for this class, or a regular search engine or both.

Significant climatic anomalies over past several years, 1998-2008
