Ancient fossils find Pacific Ocean balances itself during global warming

A recent study has made microscopic fossils messengers from a warmer world, showing that the tropical Pacific Ocean could be much more stable—and robust—than previously thought. Analyzing nitrogen isotopes locked up in the shells of ancient plankton, scientists uncovered data that ocean nutrient upwelling, a mechanism vital to marine life, was consistent even during one of Earth’s hottest periods. The results indicate that contemporary ocean pro…

USF study: Ancient plankton hint at steadier future for ocean life

St.Petersburg, FL (SPX) Oct 06, 2025 A team of scientists has uncovered a rare isotope in microscopic fossils, offering fresh evidence that ocean ecosystems may be more resilient than once feared. In a new study co-led by Patrick Rafter of the University of South Florida, researchers show that warming in the tropical Pacific - home to some of the world's most productive fisheries - may not trigger the severe declines predicte
