Summary:
- Researchers utilized geochemical analysis of long-lived coral skeletons to reconstruct historical sea surface temperature data, providing a high-resolution look at El Niño-Southern Oscillation (ENSO) patterns over the past 400 years.
- The study concludes that the intensity of El Niño events has significantly increased since the mid-20th century, suggesting that anthropogenic climate change is altering the frequency and severity of these global weather phenomena.
