GoKawiilEl Nino Pacific Temperature Anomaly Hits Record 3.05C, Months Before Peak
Current El Nino conditions have pushed the Pacific temperature anomaly to 3.05C above the 1991-2020 average, surpassing the previous record of 3.02C set in 2015, according to NOAA data. The ONI metric, which uses a rolling 30-year baseline, is within 0.01C of its own 2015 record, and forecasters cited by The Guardian project the event could peak near 4.0C by November or December.
GoKawiil's interpretation of the reporting above, not reported fact.
An El Nino of this magnitude, combined with existing human-caused warming, could push global temperatures to unprecedented highs, with climate scientist Zeke Hausfather calling the projected peak 'mind-blowing' and describing it as potentially the largest such event in a millennium. This suggests 2027 may set a new record for hottest year on record, though such forecasts depend on how the event evolves through its remaining months.
- Pacific temperature anomaly has already broken the 2015 record at 3.05C, months before the typical El Nino peak.
- Forecast models average a peak of about 4.0C later this year, which scientists say would be historically extreme.
- The combination of El Nino heat and background global warming is expected to make future years, including 2027, likely record-breaking for global temperatures.
