There are different people groups that inhabit the arctic regions of Canada, Siberia, Alaska, and Greenland. And none of them refer to themselves as "Eskimos". It's an outsider term which may be considered "racist" or "offensive". Rather the proper name for these people groups is "Inuit" though there are also various Arctic groups apart from the Inuits such as the Aleut, Nunavut, and Yupik. So where does the term "Eskimo" come from and why has it been used to refer to people who live in the Arctic regions? Read more on Popula.

As to the rest of the article, if anyone is interested in work on the Sapir–Whorf hypothesis with far less baggage than names for snow, I have seen a lot of popsci stuff now written on research into color terminology across cultures. There are other topics like names for cardinal directions that are interesting too, but the work on color seems to be much better for broad collection of data. Wikipedia at least has a dry summary of some of the work on color naming and in particular blue green distinctions.
