Pacific Ocean warming fuels fears of powerful 'super El Nino'

Forecasters warn of a potentially powerful El Nino developing in the Pacific, with an 80% chance by July. Sea temperatures could surge 2.5°C above average, potentially breaking records and affecting global weather and coral reefs.

Lead

Forecasters are closely monitoring a rapidly warming Pacific Ocean, which they say could give rise to a powerful El Nino event with significant global consequences. According to reports from multiple sources, including the US National Oceanic and Atmospheric Administration (NOAA), there is an approximately 80 percent chance that El Nino conditions will develop by July. Sea surface temperatures in key regions of the equatorial Pacific are climbing quickly, and a large pool of unusually warm water is building below the surface, setting the stage for what some experts describe as a potentially "super" El Nino.

Coverage Comparison

Coverage from Dawn (Pakistan) and RFI (France) aligns on the core facts: rising Pacific temperatures, the 80 percent probability of El Nino by July, and projections that sea temperatures could exceed 2.5 degrees Celsius above average later this year. Both outlets note that only three El Nino events since 1877-78 have crossed the 2-degree threshold—1982-83, 1997-98, and 2015-16. However, Dawn places greater emphasis on the possibility of a record-breaking event, quoting Adam Scaife of the UK Met Office, who said this El Nino could be the strongest in decades or "even be of record strength." RFI, in contrast, underscores the potential for record global heat and chaotic weather, also highlighting the impact on coral reefs.

Key Claims

NOAA has stated there is an 80 percent chance of El Nino developing by July, as reported by both Dawn and RFI.
Sea temperatures in the equatorial Pacific are rising rapidly, with forecasts from several weather services predicting an increase of 2.5 degrees Celsius or more above average later this year, according to both sources.
Only three El Nino events since the first major one in 1877-78 have exceeded 2 degrees Celsius: 1982-83, 1997-98, and 2015-16, as noted by both outlets.
Adam Scaife, head of long-range prediction at the UK Met Office, told AFP that "there's definitely something coming" and it could be a big event, possibly of record strength. This quote appeared in both Dawn and RFI reports.
Michelle L'Heureux, NOAA's El Nino-Southern Oscillation lead, cautioned that the event's final strength depends on low-level winds that are difficult to predict months in advance, as reported by both sources.
RFI reported that El Nino tends to peak around December, and ocean heat released slowly can push global temperatures higher in subsequent years, contributing to record-breaking years.
Coral reefs have already suffered repeated bleaching as oceans warm, and every global coral bleaching event has occurred during an El Nino year, according to RFI.
Dawn reported that climate scientists interviewed by AFP said global heat records could fall in 2026, though this projection is attributed to a single outlet and remains unverified.

Perspectives

NOAA and Scientific Community

Forecasters express high confidence that an El Nino will form, but they remain cautious about its strength. NOAA's Michelle L'Heureux emphasized the role of unpredictable winds: "When that happens, it pauses the growth of El Nino or even reverses it." The one-in-three chance of reaching 2 degrees Celsius or above indicates significant uncertainty.

UK Met Office and Expert Optimism

Adam Scaife of the UK Met Office is more bullish, suggesting this El Nino could be the strongest in decades or "even be of record strength." His confidence stems from observed ocean conditions, though he acknowledges atmospheric factors are still evolving.

Environmental Concerns

RFI's coverage highlights the impact on coral reefs, noting that every global coral bleaching event has occurred during an El Nino year. With oceans already under stress from climate change, a powerful El Nino could exacerbate bleaching, posing fresh threats to marine ecosystems.

Climate Change Nexus

Both sources note that it remains unclear whether Earth's warming is influencing El Nino's intensity. While El Nino is a natural climate pattern, the underlying warming trend could amplify its effects, a question that scientists continue to investigate.

Temporal Context

The last El Nino event in 2023/24 was weaker than episodes in 1982/83 and 1997/98, according to Dawn. If a strong event develops, it could follow a period of record global temperatures, potentially leading to new heat records in 2026, as some scientists told AFP. However, these projections are preliminary, and the event's evolution will depend on atmospheric conditions in the coming months.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
