The BBC has useful climate change pages with a dropdown glossary for anyone muddling 'CFC', 'CO2' and 'COP15'.

National Geographic has an excellent graphic that explains CO2 in terms of a carbon bathtub.

In its guide getting up to speed on the climate talks, Tcktcktck links to Grist's Copenhagen section and the Ecologist's Copenhagen in 60 seconds.
