Mechanism of Intensity

• This event is being monitored using both surface and sub-surface Pacific temperatures, with predictions that waters will warm by more than 2°C by year-end, effectively functioning as an energy-storing battery.2:34
• The global climate baseline—currently 1.4°C above pre-industrial levels—means an El Niño can push temperatures up by an additional 0.2°C to 0.3°C, heightening the intensity of existing climate extremes.3:33

Economic Transmission

• Historical data from the 1998 El Niño, which caused approximately $5.7 trillion in damages and rippled for five years, suggests that the macroeconomic consequences of these events are multi-year and severe.1:07
• Panama Canal traffic, a vital artery for global energy, already saw a plunge in 2024; the Canal Authority is currently enforcing cargo limits to manage drought conditions that threaten to increase liquid natural gas shipping costs.8:05
• Agricultural volatility in tropical regions like West Africa—where yield impacts in cocoa are already being observed—is expected to drive up consumer prices for goods like chocolate and hot cocoa going into 2027.5:45
• Recent extreme weather, such as India’s fifth driest June followed by a month’s worth of rain in one week, highlights how agricultural-heavy economies face high volatility that risks global food supply chains.5:11
