On the basis of a unique global comparison of data from core samples extracted from the ocean floor and the polar ice sheets, researchers have now demonstrated that, though climate changes have indeed decreased around the globe from glacial to interglacial periods, the difference is by no means as pronounced as previously assumed. Until now, it was believed that glacial periods were characterized by extreme temperature variability, while interglacial periods were relatively stable.
