A new study appeared examining Arctic air and thermal temperature changes. The Arctic Report Card found that air temperatures there are rising higher faster than the rest of the world’s warmer areas. It could be that warm air rises and moves north to gather near the pole. That idea can’t be blamed on the scientists who did the study, it was what occurred to me. That and the fact that the pole is at the center of the world’s spin rather than at the outside, so warm air would tend to remain there better.
In my opinion the situation will remain that way just until the Arctic nears a saturation point for melting. Then it will have excess warmth to spill back south to rapidly increase world temperature outside the Arctic.
