EL NIÑO READY

Forecast peak DECEMBER 2026

The costliest El Niño in history is forming right now.

NOAA puts the odds at 69% that this becomes the strongest El Niño ever measured — and it peaks in three months. Hundreds of millions of people will feel it in their power, their water, their livelihoods. El Niño Ready is a volunteer effort with one idea at its core: to save lives through communication. Forecast disasters are preventable ones. Warnings reach people. Money moves early. Systems hold.

We intend to leverage Climate Week to point at the storm already on the horizon: to underscore that it's here and growing in strength, and to alert the world that we can prepare, in the hope of saving lives.

Our only ask: have the host of your Climate Week event address the crowd for two minutes, from the main microphone, about El Niño. Include your email above and we'll send you five talking points. That's it.

“The models are forecasting something outside the envelope of anything we have ever observed.” — Zeke Hausfather · climate scientist, Berkeley Earth · The Climate Brink, July 2026

How bad? Here’s what the forecasts actually say.

  • The Pacific is forecast to hit +3.9 °C or more — nearly a full degree beyond anything ever measured. 91 of every 100 model runs break the all-time record.
  • 49 million more people won’t have enough to eat by the end of next year — joining 225 million already going hungry.
  • Central America gets hit hardest: the number of hungry people there nearly doubles — the fastest deterioration anywhere on Earth.
  • $17.6 trillion — what economists project this costs the world over the five years that follow. Most of it is still preventable.
  • Indonesia is already burning — more fires so far this year than any year ever recorded. Last time a super El Niño dried out the peat, an estimated 100,000 people died from the smoke.
  • Then come the epidemics — malaria, dengue, cholera. They have followed the shifted rains of every major El Niño.
  • And 2027 is forecast to be the hottest year humans have ever lived through — by a wide margin.

Power

Heat waves, storms, and drought-strained hydropower push grids past their limits — exactly when people need cooling, pumping, and communication most.

💧

Water

El Niño redraws the rain map: drought where communities expect rain, floods where they don't. Reservoirs, wells, and crops all sit downstream of that shift.

🏠

Livelihoods

Fisheries collapse, harvests fail, supply chains snarl. The people hit hardest are the ones who never attend a climate conference.

New York Climate Week is three months before the peak.

Every September the climate community gathers in New York. This year the world's largest climate gathering lands three months before the strongest El Niño ever measured reaches its peak.

Imagine Climate Week pointed at the storm: what the science says, what's already happening, and what we can still do about power, water, and communication before the peak.

Imagine coming out the other side of El Niño with something different to say — because of what we did together.

Together we can save lives.

Between Climate Week and the El Niño peak there are roughly three months. That's not long enough to stop it — it's exactly long enough to prepare for it, and to prove that a climate event can be met with a plan instead of a shrug.

Power systems

Harden grids for heat and storms, stage backup power for critical services, and get demand-response plans in place before the stress arrives.

Water systems

Pre-position storage and treatment where drought and flood risk is elevated, and get reservoir and well contingency plans out of the drawer.

Communication

Forecasts only matter if they reach people in time, in their language, with something actionable attached. Build the channels now.

The conversation

Use a live, global climate event to expand who talks about climate — from the people already at the conference to the people living the impacts.
