Coral records show stronger recent eastern Pacific ENSO variability
Geochemical measurements from Galápagos corals spanning the past millennium show a large recent increase in interannual eastern equatorial Pacific sea-surface temperature variability, associated with stronger El Niño events. The increase exceeds simulated natural variability in the study's comparisons and parallels rising global temperatures. The authors provide long-term context but do not establish a definitive human-warming attribution for the trend.

What if a thousand-year coral record could change one harbor's calendar?
Part one
The Warm Current
At dawn, Lale weighed the first fish baskets and marked each one for the smokehouse or the market. Years after Galápagos coral records revealed stronger recent eastern-Pacific swings, the harbor's planning calendar stopped promising a single El Niño window. The long record widened the range of seasons the local model had to consider; it could not tell Lale exactly when the next warm current would arrive.
Her mother ran the smokehouse and trusted the calendar she had used for thirty years. Lale had promised the school a steady supply for the wet months, but the fishers were bringing in their catch earlier than expected. The climate service had issued two possible windows and one uncertain tide report. The smokehouse had a single working rack, and her mother's hands were already sore from the first batch.
Lale could dry the whole catch now or hold half in cold storage until the next report. She divided the baskets and moved the first row into the kiln. A buoy alert arrived before the doors closed: the current had turned warm on the outer reef.
What’s real
- The Galápagos coral record spans the past millennium.
- Recent eastern-Pacific variability exceeded simulated natural variability in comparisons.
- The study does not settle human-warming attribution.
What’s invented
- Lale, her mother, and the harbor calendar are fictional.
- The local forecast, smokehouse choice, and buoy alert are invented.
- The paper does not predict this harbor’s fishing schedule.
