I'm glad Zach brought that up, but honestly it's really old news. The "official" weather stations were usually in the oldest parts of cities, e.g. at the civic center and now surrounded by cars and pavement, or at airports because weather is important to planes. Anyway, early on in the warming hysteria, the urbanization of weather stations was pointed out. Then drowned out, apparently.
