El Niño Reaches Record Levels, Global Heat Risks Rise
The El Niño phenomenon has reached record-breaking levels, with sea surface temperatures in the tropical Pacific exceeding 3°C (5.4°F) above average as of mid-September 2026. The World Meteorological Organization (WMO) predicts the event will peak by the end of the year, potentially becoming the strongest El Niño on record. This natural climate pattern is amplifying global temperatures already heightened by climate change, with severe impacts expected worldwide. A study by Climate Impact Lab estimates that 451,000 heat-related deaths could occur between September 2026 and February 2027, with the Global South bearing the brunt of the crisis. Countries like Nigeria, Sudan, and Indonesia are projected to experience the highest mortality rates due to extreme heat, while California has declared a state of emergency to prepare for potential severe weather.
