El Niño 2027: A Climate Crisis Preview
TL;DR
A record-breaking El Niño expected in 2027 could push global temperatures to unprecedented levels, offering a preview of climate conditions in 2035 while highlighting vulnerabilities in disaster response and adaptation.
Key Takeaways
- 1A 'Godzilla El Niño' arriving in late 2026 could set global temperature records and disrupt weather patterns worldwide, with cascading impacts on crops, monsoons, and extreme weather.
- 2Despite political opposition to renewables, 90%+ of new US energy infrastructure in 2024 was green energy, driven by dramatic cost declines in solar, wind, and battery technology.
- 3Climate anxiety in America is at historic highs, yet political discourse has largely abandoned climate action as a priority, creating a disconnect between public concern and elite policy.
- 4The most vulnerable populations will bear the brunt of El Niño impacts through food insecurity and climate disasters, while wealth provides only imperfect protection against extreme events.
- 5Rapid green energy adoption in developing nations like Pakistan and Nepal suggests decarbonization is economically driven rather than policy-dependent, offering some cause for optimism.
Notable Quotes
“For every unit of new fossil fuel infrastructure we were building, we built 9 times as much green energy.”
— David Wallace-Wells
“Privilege is not a perfect protection against these impacts.”
— David Wallace-Wells
“We are heading towards a future that we defined as unacceptable.”
— David Wallace-Wells
“The green transition is proceeding at a breakneck pace, much faster than even its biggest boosters said was possible 10 or 15 years ago.”
— David Wallace-Wells
Chapters
1. Understanding El Niño and Its Global Impact
David Wallace-Wells explains that El Niño is a recurring climatic event occurring every 3-7 years, characterized by warmer-than-normal Pacific temperatures off South America with global teleconnections. This particular El Niño is unprecedented in size and intensity, with scientists calling it a 'Godzilla El Niño.'
2. Historical Context and Catastrophic Potential
Historical El Niños, particularly in the 1870s, caused famines killing tens of millions. While modern infrastructure may prevent similar death tolls, significant crop failures across multiple regions could trigger political instability, bread riots, and civil unrest, especially given current fertilizer shortages from geopolitical conflict.
3. Regional Effects and Uneven Distribution
El Niño effects will vary by region: the US Gulf Coast and Florida will see fewer hurricanes; California faces intense rainfall and potential mudslides; the American West risks severe wildfires followed by flooding. Less privileged communities will experience disproportionate impacts despite some regions seeing temporary relief from water scarcity.
4. Climate Goals and Inevitable Warming
The world has already reached 1.5°C warming and is heading toward the 2°C threshold, which the Paris Agreement deemed unacceptable. This inevitable future contradicts the urgency and fear that motivated global climate action 6-8 years ago, including Greta Thunberg's activism and the Green New Deal.
5. The Disconnect Between Anxiety and Action
Despite Americans being more worried about climate change than at any previous point, elite discourse and policy have largely abandoned climate as a priority. However, surveys show sustained anxiety levels, suggesting political failure to channel public concern into meaningful action.
6. Economics of Renewable Energy Transition
Solar, wind, and battery costs have dropped so dramatically that renewable power is now cheaper than fossil fuel alternatives, even accounting for system-wide infrastructure. The levelized cost of electricity continues to decline for renewables while remaining flat for fossil fuels, making the economic case for transition overwhelming.
7. Green Energy Progress Despite Political Headwinds
Despite Trump's opposition to renewables, over 90% of new US energy infrastructure built in 2024 was green, with 2025 expected to reach 93%. Globally, countries like Pakistan doubled solar capacity within years, and developing nations are adopting EVs and solar power faster than wealthy nations, driven by economic logic rather than policy mandates.
8. Disaster Response and Federal Preparedness
FEMA reorganization and the Trump administration's push to shift disaster response to states raises vulnerability concerns, as states cannot deficit-spend for crises like the federal government can. This creates risk heading into 2027 if the El Niño produces major extreme weather events.
9. Geopolitical Instability and Energy Security
Trump's fossil fuel-focused foreign policy, including attempts to control Venezuelan oil and escalating Iran conflict, has paradoxically accelerated global renewable adoption as countries seek energy independence. However, erosion of international cooperation institutions may hinder coordinated climate response.
10. Adaptation Uncertainty and Grounds for Measured Hope
While adaptation capacity remains uncertain given the scale of climate disruption ahead, major progress in renewable energy transition, electrification efficiency, and air pollution reduction provides grounds for cautious optimism. Future outcomes will likely be mixed—manageable in some domains, catastrophic in others—requiring continued innovation and political evolution.

Glossary
- El Niño
- A climatic event occurring irregularly (every 3-7 years) characterized by warmer-than-normal ocean temperatures in the coastal Pacific off South America, producing global weather disruptions through teleconnections.
- Teleconnections
- Scientific relationships between weather events in different parts of the world, where patterns observed in one region correlate with patterns in distant regions, even when the exact causal mechanisms are not fully understood.
- Godzilla El Niño
- An exceptionally large and intense El Niño event with temperature increases potentially larger than any recorded in modern history (since the 1870s-1880s).
- Levelized Cost of Electricity (LCOE)
- An industry standard measure of electricity generation costs that accounts for marginal production costs, though it does not capture full system costs including energy storage and distribution infrastructure.
- Teleconnections
- Scientific relationships between weather events in different parts of the world where patterns in one region correlate with patterns in distant regions, even when exact causal mechanisms remain unknown.
- Paris Agreement
- A 2015 international treaty committing nations to limit global warming to well below 2°C and pursue efforts to limit it to 1.5°C above pre-industrial levels.
- Atmospheric Rivers
- Narrow bands of concentrated moisture in the atmosphere that can produce intense precipitation events and flooding, increasingly common during El Niño years in the western US.
