Antarctica's ancient ice sheets foreshadow dynamic changes in Earth’s future

Researchers analyzed Antarctic sediment records to understand past ice sheet behavior, finding frequent and rapid growth and recession cycles over thousands of years. The study suggests that climate factors beyond Earth's orbit may trigger these changes, potentially leading to unexpected ice sheet dynamics in the coming centuries.
