Why A Record-Hot Ocean Is Supercharging The El Niño Effect
A strengthening El Niño over record-hot oceans could reshape weather worldwide. Here’s what it means, how it affects us, and what we can still do.
- Global sea surface temperatures reached a record 21.2°C in early 2026, the highest since satellite records began in 1979, according to NOAA.
- The current El Niño, declared strong in June 2026, is projected to persist through February 2027, with peak intensity expected in December 2026.
- During the 2015–16 El Niño, agricultural losses exceeded $10 billion globally; the current event could surpass that due to higher baseline ocean heat.
