ScienceCorals as climate archives: Are El Niños intensifying?

Recent records show frequent and often extreme El Niño events, but it remains unclear whether this is natural variability or a result of climate change. By examining living and fossil corals near the Galápagos Islands, researchers reconstructed ocean temperatures over 1,000 years and found that El Niños have become markedly stronger than in the pre-industrial period. Other scientists remain cautious about the study’s significance.
