… abrupt shifts of northern hemisphere atmospheric circulation resulting in 2-4°K changes in Greenland moisture source temperature from one year to the next.
The article concludes that
… polar atmospheric circulation can shift in 1-3 years resulting in decadal to centennial scale changes from cold stadials to warm interstadials/interglacials associated with astounding Greenland temperature changes of 10°K. Neither the magnitude of such shifts nor their abruptnesses are currently captured by state of the art climate models.
