An extraordinarily powerful storm system is spinning across the North Atlantic
Ocean, just southeast of Greenland. Together with long-term climate change and
other transitory weather systems, it is setting the stage for a dramatic and
unusual warmup at the North Pole this week.

For the third time this winter, such a storm is likely to vault unusually warm
air toward the pole, potentially bringing temperatures across the sunless Arctic
to near the melting point for a brief period late this week.
