I made a three minute video about lakes disappearing from Google Maps satellite photos and a rainy day in Copenhagen for Climate Change TV. Check it out.
If you like it, head over to the competition website and vote for it, please.
I haven't had the time to watch all of the other videos yet. But among those I have seen I'd mention The world has malaria and What happened at COP16? Got another favorite? Let me know and I'll check it out.
