New high-resolution speleothem records from China and India, together with isotope-enabled climate models, show that abrupt glacial ocean circulation recoveries took centuries, not decades—a finding with important implications for how we assess future Atlantic circulation change. The work is published in the journal Science.

📋 Key Takeaway
A new study reveals that abrupt climate shifts during the ice age occurred over centuries rather than decades, based on high-resolution speleothem records from China and India. This research has implications for understanding future changes in Atlantic circulation, which could affect global climate patterns. For Iran, this could influence agricultural and water resource management amid climate change.
