Northern Ice Sheets May Have Sent a Cold Signal South That Helped the Southern Ocean Lock Away Carbon, Model Suggests

Cooling only the far northern latitudes of an idealized ocean model produced 74% of the carbon dioxide drawdown seen when researchers cooled the entire planet, a University of St Andrews-led team reports in the Journal of Climate. The result suggests a way growing ice sheets in the Northern Hemisphere could have pushed the Southern Ocean around Antarctica to store more carbon during past ice ages, according to a university summary.
