Harvests rose nearly 30%

02/05/2026 Go to Evidence

Nearly 30% was the year-on-year increase in grain harvests during intense El Niño events, such as 1997 and 2014-2016, due to productivity gains.

Super Niño may push global temps to +2°C

21/04/2026 Go to Evidence

Climate models indicate the 2026 El Niño could be the strongest on record. It is estimated 50% chance of a "strong" or "very strong" event during the upcoming Northern Hemisphere winter. Some models project global temperature anomalies exceeding +2°C (Alessi,2026)

3 years above 1.5°C sharpen agriculture risk

21/04/2026 Go to Evidence

The years 2023–2025 averaged more than 1.5°C above preindustrial levels, with 2024 being the hottest year on record. A super El Niño on top of this baseline worsens crop yield impacts in the Caribbean, where El Niño historically generates droughts, heatwaves, and water stress that reduce production of key crops such as maize, beans, and sugarcane.

LAC: 50% hydro energy at risk from El Niño drought

20/04/2026 Go to Evidence

50% of Latin America's energy comes from hydroelectric sources, making the region highly exposed to El Niño; droughts force reliance on costlier thermal plants, raising agricultural production costs (Castellanos, 2026).

Dry Corridor and Caribbean face drought risks

20/04/2026 Go to Evidence

26% of climate disaster damages in LAC are absorbed by the agricultural sector on average, rising to 82% during droughts; equatorial Pacific warming also severely impacts Caribbean coastal fisheries (Castellanos, 2026).

Caribbean: 61% El Niño probability threatens crops

13/04/2026 Go to Evidence

61% probability is estimated by WMO that El Niño will bring severe droughts to Belize, Guyana, Suriname, Jamaica, and Trinidad and Tobago, threatening crops and water supplies in countries already facing high imported food prices due to the Iran conflict (The Guardian, 2026).
