A strong El Niño event intensifying through 2026, layered on long-term greenhouse gas-driven warming, has driven January–August global surface temperatures to the second-highest levels on record behind only 2024, with August 2026 setting a new monthly record across NOAA, NASA, and Copernicus datasets. El Niño’s ocean-to-atmosphere heat release typically peaks the calendar year after onset, supporting the high implied probability that 2026 finishes first or second; historical analogs show the post-peak year often claims the annual record. NOAA’s year-to-date analysis places 2026 among the top five with near-certainty while assigning lower odds to a new record without fully weighting the current El Niño strength, whereas climate analysts such as Zeke Hausfather estimate roughly 75% odds for 2026 topping the list. Final rankings hinge on September–December anomalies and agency syntheses.
