Super El Niño could turn weather shocks into global disruptions
The Global Story: The Super El Nino - what happens when it hits us?
The episode connects a major Pacific climate event to heat deaths, food insecurity, shipping problems and the practical choices that can limit harm.
- 1El Niño can trigger linked droughts, floods, wildfires, crop losses and water shortages across distant regions.
- 2Improved Pacific monitoring now gives governments substantially more time to forecast risks and organize early warnings.
- 3Preparation matters: emergency supplies, evacuation plans and clear public communication can turn climate information into protection.

Tom Di Liberto explains how Pacific monitoring buoys transformed El Niño from a surprise into a hazard governments can forecast and prepare for.
The brief
Climate scientist Tom Di Liberto traces El Niño from Pacific trade winds and ocean temperatures to weather disruptions spanning Australia, India, Central America and beyond.
The episode follows the domino effects: drought, weakened monsoons, wildfires and water shortages can damage crops, raise coffee prices and disrupt shipping through the Panama Canal.
A projected rise in heat-related deaths gives the phenomenon a human scale, while Tom places the risk alongside climate change and recent heat mortality in Europe.
The 1982–83 and 1997–98 events arrived with less warning; today, Pacific monitoring buoys give scientists a stronger chance to forecast danger early.
Tom’s argument is practical rather than fatalistic: governments and households can use forecasts to prepare for flooding, mudslides, outages, heavy rain and extreme heat.
