Climate change: The south–north connection
Eric J. Steig1
Abstract
A new ice-core record from Antarctica provides the best evidence yet of a link between climate in the northern and southern polar regions that operates through changes in ocean circulation.
Over the past 20 years, the analysis of ice cores has been transforming our understanding of past climate. Most notably, the Vostok core from Antarctica1 provided remarkable evidence of the correspondence between temperature and atmospheric carbon dioxide concentrations over the past 420,000 years.
