The new one is on climate change and it has excellent climatology and economics (although there are no economists speaking) in the video. The economics is primarily statements about externalities, that what you do doesn't just affect you it affects lots of other people. They didn't give the complete story, of course - they didn't really go into what good social science predicts human beings will do in such a situation. But it's still great to see that in there.
The music in this one is not my favorite (believe it or not, sometimes remixing science lectures isn't melodious), but I still enjoy listening to new products of the project.
