Igloos were the original geodesic dome. With all due respect to Bucky Fuller, the Inuit's had this figured out long ago. You know, like Columbus discovered America? Hello, there were people already here, ok?

If you think snow is cold, then what's with this Wikipedia explanation of igloo insulation: snow is an insulator (due to its low density). On the outside, temperatures may be as low as -50 degrees Fahrenheit (-46°C), but on the inside, the temperature is much more moderate and can support life.

Life, dude! Snow's not cold! Throw on a little light, whistle for the Siberian Huskie, grab your main squeeze, tune in Leno, chew on some blubber, open some fine wine… this winter thing cool hot!
