Links to 'global warming' dictionaries/glossaries

Here are some links to three global warming glossaries
(a glossary is like a dictionary)
1. http://www.epa.gov/climatechange/kids/glossary/index.html
This may be a site for kids, but it does provide good definitions that are easy to find.

2. http://www.globalwarming.org/article.php?uid=123
This is a more serious site, but it is not as easy to use. Scroll down until you reach the initial letter of the term you want to understand.
Ie. G for Greenhouse Effect

3. http://en.wikipedia.org/wiki/Glossary_of_climate_change#G
This is the wikipedia glossary, which provides links to the words you want to understand. Scroll down to the initial letter, or use Control + F and type in the word, and then click Find Next
