I was posting that link in response to this:

I feel compelled to point out that an "igloo" is a cartoon invention, as far as I can tell. I would LOVE to see a link to any indigenous people using an igloo as a normal part of their daily lives. I found lots of variations on the practice of making a temporary shelter out of ice/snow, but none of them are what I'd consider an igloo.
We don't have such an igloo, we have the iconic cartoon like structure, but yes, i realize we need something to block up the door to provide some heat... and I think the heat source on the interior (assuming everything is sealed properly) shouldn't need to be dramatic to provide noticeably higher temp than the exterior.
