1. Antarctic and global climate history viewed from ice cores

Abstract

A growing network of ice cores reveals the past 800,000 years of Antarctic climate and atmospheric composition. The data show tight links among greenhouse gases, aerosols and global climate on many timescales, demonstrate connections between Antarctica and distant locations, and reveal the extraordinary differences between the composition of our present atmosphere and its natural range of variability as revealed in the ice core record. Further coring in extremely challenging locations is now being planned, with the goal of finding older ice and resolving the mechanisms underlying the shift of glacial cycles from 40,000-year to 100,000-year cycles about a million years ago, one of the great mysteries of climate science.A discussion of past Antarctic and global climate history as seen from Antarctic ice cores, with an outlook on future goals and drilling priorities., Author(s): Edward J. Brook [sup.1] , Christo Buizert [sup.1] Author Affiliations:(1) College of Earth, Ocean, and Atmospheric Sciences, Oregon State University, Corvallis, USAMain The origins of the Antarctic ice sheet [...]
