Summary:
- Researchers utilized geochemical analysis of long-lived coral skeletons to reconstruct El Niño-Southern Oscillation (ENSO) patterns over the past 400 years.
- The study provides robust evidence that anthropogenic climate change has intensified the frequency and severity of extreme El Niño events compared to pre-industrial baselines.
- The findings bridge a critical data gap in paleoclimatology, demonstrating that current equatorial Pacific climate volatility is unprecedented in the context of the last four centuries.
