> If Greenland ruled the world we would all be discussing some nonsense about how easily sleds glide over ice. This criticism only makes sense if you believe that Greenland could realistically have ruled the world with no significant differences in geography or technology to our real world. If we stumbled upon some alternative universe where Greenland in fact was the dominant empire, the idea that something was different enough in their universe such that colder climates were an advantage would absolutely be the first thing investigated. > Nevermind that this supposes a geographic explaination [...] But an economist examines it through economic policy, an anthropologist through culture.. I don't know if you read the first article in this series, but the author definitely touches on those factors, particularly with regards to the Silk Road, and how empires can thrive through competition if they're close (but not too close).
