Configuration of circum-Antarctic circulation at the last green- to icehouse climate transition
drawdown, and Southern Hemisphere gateway opening alone were insufficient to establish a strong ACC [Formula: see text]34 Ma. Only the later alignment of westerly winds with open oceanic gateways enabled the enhancement of interhemispheric overturning circulation, promoted carbon uptake, and the long-term stabilization of Earth's icehouse climate.
