The Next El Niño Could Lock Earth Into a Hotter Climate
Scientists project a strong El Niño event in the next 12-18 months, potentially pushing the global average temperature past the 1.5°C warming threshold. A strong El Niño could lead to abrupt, lasting changes in heat, rainfall, and drought patterns, amplifying climate impacts.
The Pacific Ocean is a significant climate driver, with El Niño events affecting global temperatures and weather patterns. Scientists predict a strong El Niño in the next 12-18 months, potentially pushing the global average temperature past 1.5°C above pre-industrial levels. El Niño events release stored ocean heat, influencing weather patterns, and can lead to climate regime shifts. In 2015, an El Niño event helped raise the global temperature past 1°C above pre-industrial levels. Climate scientist James Hansen warns that even a moderately strong El Niño could drive the average global temperature to 1.7°C above pre-industrial levels. Passing the 1.5°C threshold may lead to rapid changes in relatively stable climate systems.
