> All the while, fiercer heat waves will require more energy-hungry air conditioning to keep people healthy. (Though ideally, everyone would get a heat pump instead.) An air conditioner is a heat pump. I'm not sure the distinction they're trying to make here. What we normally call heat pumps can provide efficient heating as well, but that's not relevant in summer. Modern heat pumps can be more efficient than older ones, but so can modern air conditioners that don't have a heating cycle.
