The current rates show that there is a large region of low accumulation to the northeast of central Greenland with drops in accumulation rate of 25% 150 km, and 50% 300 km from Summit. Relatively large variations in accumulation rate over time are seen in ice cores. The resulting accumulation-rate record, which should be related to changes in local air temperature over northern Greenland, has been compared with Scandinavian tree-ring records and the data shows an early Medieval Warm Epoch, but no pronounced "Little Ice Age' and no unequivocal greenhouse warming effect as yet in northern Greenland. -from Authors
