Anti-phased changes in Antarctic Circumpolar Current strength over orbital timescales

Key Points

• Anti-phased changes in the Antarctic Circumpolar Current correlate with significant climate shifts.
• Data indicates strength fluctuations of the current aligned with 100,000-year orbital cycles.
• Analysis of sediment core records illustrates historical changes in ocean circulation patterns.
• These findings highlight the long-term impact of orbital changes on global climate systems.
