This article is all over the place. Skyscrapers are one thing, but your run-of-the-mill residential (not-so-)highrise is not one, and every study I've ever seen indicates that it's environmentally much more friendly to live in high-density housing: less heating/cooling costs that a single-family home (yes, even with those glass windows), cheaper construction and maintenance, less transport externalities, etc etc.
