The Heat Isn’t Over: Scientists Eye a Powerful Super El Niño

Scientists say a “super El Niño” is loading the dice for another heat spike, even though 2026 itself is not yet smashing records.

2026 Heat: Hot, But Not Yet Another Record

Global temperature data so far in 2026 show intense heat waves and above-normal warmth, but they have not clearly beaten the records set in 2024. Carbon Brief’s analysis of 667 climate model runs finds that 2026 has about a one-in-three chance of edging out 2024 as the hottest year, but the central forecast still puts it in second place. That means people feeling this year’s heat are not imagining it, yet the most likely story is “near-record” rather than “worst ever.”

Climate scientists stress that this near-record heat is happening before El Niño fully kicks in. The World Meteorological Organization says the Pacific Ocean pattern known as El Niño is expected to emerge during the summer and autumn of 2026 and may persist through the end of the year. Once that pattern strengthens, it usually adds a small temporary boost to global temperatures on top of the long-term warming trend driven by greenhouse gas emissions.

What A Super El Niño Actually Does

El Niño happens when a wide strip of the tropical Pacific Ocean becomes warmer than normal, which then disrupts weather across the globe. The Climate Prediction Center and other modeling groups now see El Niño conditions already present and likely to intensify into the winter of 2026–27, with roughly a 63 percent chance of a “very strong” event that ranks among the largest since 1950. Carbon Brief’s review of 14 models suggests sea surface temperatures in the Niño 3.4 region could peak around 3.6 degrees Celsius above average, well past the “super El Niño” threshold.

Scientists explain that this ocean heat does not translate into instant global records; instead, the effect on worldwide temperature usually lags the Pacific changes by three to five months. A National Oceanic and Atmospheric Administration meteorologist quoted by Phys.org says a typical El Niño boosts the global average by only about 0.1 to 0.2 degrees Celsius for a short time. Because the background climate has already warmed by over one degree since pre-industrial times, that small extra push can still make the difference between “near record” and “new record.”

Why Many Forecasts Point To 2027, Not 2026

Several leading experts now argue that the biggest record-breaking risk comes in 2027, after El Niño has had time to work through the system. Zeke Hausfather, a scientist with Berkeley Earth, told National Public Radio that a robust El Niño would raise temperatures slightly in 2026 but have its strongest impact in 2027, which he calls the more probable year to set a new global record. USA Today and Time echo this view, noting that headlines about a “mind-blowing” El Niño should not be confused with a guarantee that 2026 will be number one.

Carbon Brief’s own numbers support this timing shift, even as they warn about the near-term heat. Their central estimate puts 2026 at about 1.51 degrees Celsius above pre-industrial levels and gives it a 35 percent chance of beating 2024, while projecting an even higher chance that 2027 will claim the top spot once the delayed El Niño effect fully shows up. This is a classic case of a natural climate swing, El Niño, stacking on top of a human-driven warming trend and turning probabilities into headlines that can sound more certain than the data truly allow.

Shared Public Frustration: Hotter World, Little Trust

For many Americans, the details of ocean temperatures and model ensembles matter less than the daily reality of hotter summers, rising electric bills, and more extreme storms and floods. Conservatives see years of “green” policies and global climate deals as costly and ineffective, wondering why, after all the spending, the country still appears unprepared for heat waves that strain the power grid and threaten older people. Liberals see the same heat as evidence that warnings about climate risk were ignored in favor of short-term profit.

Both sides feel a common anger at a federal government that talks about climate plans while basic protections lag behind. Flood defenses fail, wildfire seasons grow longer, and the same neighborhoods face repeat disasters, yet many officials seem more focused on photo ops and reelection than on stronger infrastructure and clear, honest risk communication. The “super El Niño” story fits this pattern: real science about rising odds gets turned into drama, while working families are left to sort out how much danger they actually face and how to prepare on their own.
