Maybe the morons who wrote the article don't know the difference between 5 and 0.5 C (which is about the reported average temp increase over the last century, and some people even question that).

No, I am sure they know they are saying "5 C" on purpose. It is a mantra, a holy talisman, to find 5 C somewhere. They undoubtedly mean to imply that temperature change was much higher at the poles, or at least at one of them, than elsewhere (like, zero elsewhere? Colder? Not all regions can be above average, any more than all children in Lake Woebegone). Part of an epicycle hunt. A tiny temperature change overall is supposed to melt the ice caps, remember? Since it is tiny, that is completely implausible. So they need an untiny one, at least there.
