Strong El Niño Event Forecasted to Cause Trillions in Global Economic Losses
An El Niño event has officially formed over the Pacific Ocean, with early forecasts indicating it could be particularly intense. The National Oceanic and Atmospheric Administration (NOAA) has predicted a 63% chance of sea surface temperatures surpassing 2.0°C, a threshold for a "very strong" El Niño. This climatic phenomenon is anticipated to bring significant economic repercussions, potentially leading to trillions of dollars in global income losses.

An El Niño event has officially formed over the Pacific Ocean, and early forecasts suggest it will be an intense one. El Niño, a natural pattern associated with warmer temperatures, can significantly influence global weather patterns, leading to conditions such as drought and heavier precipitation worldwide.
NOAA announced a 63% chance of sea surface temperatures in the Pacific surpassing 2.0°C, which would signal a “very strong” El Niño. The World Meteorological Organization also projected an event that will be “at least moderate—and possibly strong,” comparable to past El Niños that accompanied substantial warming.
Historically, strong El Niño events have incurred considerable economic costs. A 2023 paper published in Science analyzed the impacts of the 1982 and 1997 El Niños, finding global income losses of $4.1 trillion and $5.7 trillion, respectively. These losses primarily stemmed from damages caused by extreme weather, including reduced agricultural output due to heatwaves and flooding. The study also projected that the cumulative economic losses from El Niño events throughout the 21st century could amount to $84 trillion.
Robert Muggah, a political scientist, highlighted the potential severity of the situation, stating that the latest outlook should serve as an early warning for governments, companies, and aid agencies to prepare for what could be a “major systemic shock.” The economic impact is expected to be particularly severe in poorer countries.
