El Niño forms early, raising stakes for insurer catastrophe models
Ocean temperatures in the Niño 3.4 region were about 2.0°C above average in mid-July, and some forecasts point to a peak near 3.6°C.
A powerful El Niño has developed months ahead of schedule, and climate scientists cited by CBC News and The Economist say it could surpass all previous events on record, creating fresh urgency for insurers' catastrophe models.
According to the reporting, ocean temperatures in the Niño 3.4 benchmark region were already running close to 2°C above average in mid-July, even though the event has not peaked. Most forecasts place the peak between October and December, and Berkeley Earth climate scientist Zeke Hausfather said some forecasting models are pointing to a possible peak around 3.6°C above average, which would exceed the 2015-2016 record near 2.75°C.
Researchers also highlighted how unusual the speed of the transition appears to be. NOAA meteorologist Nat Johnson said last winter’s conditions were still consistent with a La Niña, and the shift from that baseline to a potentially record-setting El Niño within roughly a year is unusually rapid, though it remains unclear why the swing is so pronounced or what role climate change may be playing.
For insurers, the concerns span tropical and higher-latitude exposures. The reporting notes that El Niño-linked drought risks could affect food security and spill into agricultural lines and economic stability, while Canada and other higher-latitude regions may see milder but drier winters that raise wildfire concerns into the following spring and summer.
