Notable Quotes
- When this part of the Pacific catches a cold, the whole world has a fever.
— Chico Harlan, on the global impact of El Niño.
- This event unintentionally gives us a sneak preview of where we're already going — a glimpse into the norm of the 2030s.
— Chico Harlan, on how El Niño foreshadows future climate conditions.
- The UN predicts an extra 50 million people will face food shortages because of this El Niño — almost tantamount to a war in terms of human suffering.
— Chico Harlan, on the humanitarian toll.
🌊 What Is El Niño?
- El Niño is a natural climate phenomenon in the tropical Pacific Ocean that disrupts global weather patterns.
- Normally, winds push warm water from South America toward Asia, but during El Niño, these winds weaken or reverse, causing warm water to build up near South America.
- This warming triggers atmospheric changes, reorganizing global weather systems and intensifying storms, droughts, and rainfall.
- A Super El Niño
occurs when ocean temperatures rise 2°C above normal; this year, temperatures could exceed a 3°C increase, an unprecedented level.
📜 Historical Context and Devastation
- El Niño's impacts have been observed for centuries, with Spanish colonists in the 1600s naming it El Niño de Navidad
after noticing unusual fish patterns.
- A severe El Niño in 1877 caused a famine that killed 50 million people, making it one of the worst environmental disasters in history.
- Only in the mid-20th century did scientists begin to understand El Niño as a global phenomenon.
🔥 Current Impacts of the 2026 Super El Niño
- Already affecting three continents:
- Panama: Lack of storms threatens the Panama Canal, which relies on rain-fed lakes.
- Africa: Ethiopia and Kenya face record droughts, leading to poor harvests.
- India: The country experienced its fifth driest June, raising concerns about food security.
- The UN predicts 50 million additional people will face food shortages due to this event.
🌡️ El Niño and Climate Change
- Climate change amplifies El Niño's effects, making droughts, floods, and heatwaves more severe.
- While there’s no consensus on whether climate change increases the frequency or intensity of El Niño events, recent decades suggest stronger occurrences compared to the past 600 years.
- This year's El Niño offers a sneak preview
of the extreme weather expected in the 2030s due to global warming.
📅 What Lies Ahead
- El Niño typically lasts 12–15 months, but its effects, especially heat, linger.
- Historically, the year following an El Niño is the hottest on record. Scientists predict 2027 will break global temperature records by a significant margin.
- The current event underscores the urgent need for global climate action as it accelerates the timeline for experiencing extreme climate conditions.

📋 Episode Description
The global chaos agent known as El Niño is back, and this year it’s already on track to be, by far, the strongest and most severe on record, wreaking havoc on weather across the world.
Today, Chico Harlan, the global climate reporter for The New York Times, goes over El Niño’s history, its inner workings and its increasingly destructive fallout.
Guest: Chico Harlan, the global climate correspondent for The New York Times.
Background reading:
- El Niño, the Pacific climate shift that comes around once or twice a decade, is back, warming tropical oceans and setting off consequences worldwide.
- It’s expected to peak later this year but is already causing dry spells and crop failures on three continents.
