Iain Stewart on the Carbon Cycle

I shared a BBC Taster 'experimental website' where you could choose an adventure for Simon Reeve a few months ago, and the latest website in the series of trials features Professor Iain Stewart talking about the Carbon Cycle - a special revision resource for 'A' level Geographers especially.
Check it out !

Did I tell you about the time Iain presented me with a medal ? I don't like to talk about it though....
