New UH ‘Wyrtki-CSLIM’ Model Flags Potential 2026-27 Super El Niño 15 Months Ahead

Climate forecasters have chased longer-lead ENSO skill since the 1982-83 and 1997-98 super El Niños rearranged global weather and economics; in both cases warnings came barely six months out. By distilling two half-century-old ‘memories’—Wyrtki’s Pacific heat storage and Hasselmann’s global SST imprint—into a linear inverse model, UH scientists may have achieved for ENSO what the 1960s barotropic models did for mid-latitude storms: shift society from reactive to anticipatory stance. The timing is critical: greenhouse forcing has already nudged baseline temperatures ~1.5 °C above pre-industrial, so each additional El Niño pulse now rides a higher platform, amplifying heatwaves like India’s 45 °C April surge and stressing food-water systems much as the 1877-78 ENSO-linked drought triggered colonial-era famines. If the new forecasts verify, they buy governments a full planting season of warning—small in calendar terms but enormous on a 100-year trajectory where adaptation speed will define economic winners and humanitarian losses.
