A supercharged El Niño could arrive this summer, experts predict – pushing global temperatures to record highs. 'If a strong El Niño develops, it would push up 2026 global temperatures and particularly 2027 temperatures. During a typical event, ocean water is at least 0.5°C (0.9°F) hotter than the long–term average. A 'super El Niño', meanwhile, occurs when sea surface temperatures reach at least 2°C (3.6F) above normal. A separate study, published earlier this year, revealed that ocean warming has more than quadrupled over the past 40 years.
