Perspectives

PALEOCLIMATE:
Climate Change Across the Hemispheres

Nicholas Shackleton

Climate records from Greenland ice cores have shown that climate has changed rapidly and drastically throughout the last glacial period on a millennial time scale. In his Perspective, Shackleton highlights the report by Blunier and Brook, who have correlated the Greenland records with an Antarctic record. There is a systematic difference in the character and timing of temperature changes in the two hemispheres, although the mechanism linking the hemispheres remains uncertain. Absolute dating is essential.
