Something Is Brewing in the Pacific That Nobody in Washington Wants to Talk About

SS: Meteorologist Chris Gloninger breaks down ECMWF model guidance showing a potential super El Niño forming this summer / fall, with sea-surface temperature anomalies of ~2.5°C in the Niño 3.4 region which would exceed the 1997 and 2015 events and potentially be the strongest in 140 years.

The critical difference this time is the baseline: global warming has nearly doubled its pace since 2015, meaning this El Niño would land on top of temperatures already 1.4–1.5°C above preindustrial rather than the 0.6–1.0°C baselines of previous super events.

Implications include compounding drought and flood risks across global food-producing regions, intensified atmospheric rivers hitting an already snowpack-depleted California, and potential commodity price shocks.

Meanwhile, the EPA is moving to repeal the Endangerment Finding that underpins all federal climate regulation in the US in the same week these forecasts are emerging.
