  • Abrupt disruptions to Earth’s climate thousands of years ago that caused extreme sea-level rise and mass ice cap melting can serve as an early warning system for today’s planetary tipping points.
  • Climate tipping points – which are irrevocable over centuries or longer – are thresholds past which large and rapid changes to the natural world may occur.
  • In a review of past climate events published in the journal Nature Geoscience, an international team of scientists examined two major instabilities in the Earth system, caused by changes in ice, oceans, and rainfall patterns.
