In Northern Italy - where the weather can be bad, if not ugly - they developed the Portico, where the buildings overhang the sidewalks and provide protection from rain and wind (see http://cdn.c.photoshelter.com/img-get/I00007AaJoUp4oKU/s/750...)

Sure, they don't completely isolate humans from weather conditions but these solutions significantly improve the livability and prolonged usability of an urbanization, without burning bathtubs of gasoline to keep running.

Humans are not obliged to colonize every single corner of the planet...
