The United Nations has declared that the El Niño climate phenomenon is significantly intensifying, with projections indicating it will likely break historical temperature records. Experts assert that this event could be the most substantial occurrence in over a millennium, contributing to an already warming atmosphere. Consequently, the year 2027 is anticipated to become the hottest on record.
The effects of the rising temperatures associated with El Niño are already evident, exacerbating wildfires in Indonesia and diminishing critical monsoon rains in India. The repercussions are expected to be felt worldwide, leading to heightened fire hazards in Australia and more severe flooding across South America. In August, the World Food Programme warned that nearly 50 million individuals could face acute hunger due to the impacts of El Niño.
The ongoing climate crisis, driven by fossil fuel pollution, has already been amplifying extreme weather conditions, resulting in significant fatalities. This summer, Europe experienced its most extreme heatwave on record, claiming at least 35,000 lives. The intensification brought on by El Niño is predicted to worsen these effects, with its magnitude described as “truly astonishing” and akin to a “Godzilla-level” event.
El Niño represents a natural climate cycle characterized by changes in wind patterns over the Pacific, which lead to elevated ocean temperatures and the transfer of substantial heat to the atmosphere. Recent data indicates that ocean temperatures central to El Niño have risen 2.6°C above the 30-year average, nearing the highest recorded anomaly of 3.1°C from 2015, with several months remaining before a peak is expected.
Forecasts suggest that this peak could reach approximately 4°C by November, based on an analysis of 14 different climate models. Research involving coral, tree rings, and historical records indicate that no El Niño event has reached such levels in the past thousand years, according to climate analyst Zeke Hausfather. An El Niño is categorized by any temperature anomaly exceeding 0.5°C.
Further complicating matters, recent studies reveal that global warming is intensifying El Niño cycles, which in turn exacerbate the effects of the climate crisis.
UN Secretary-General António Guterres emphasized the urgency of the situation, stating, “El Niño is being supersized before our eyes. The scientific evidence is clear: we are navigating unchartered waters, and these waters are warming. The planet is now in a precarious zone concerning extreme weather. We must act swiftly to mitigate these risks and safeguard communities.”
Celeste Saulo, Secretary-General of the UN’s World Meteorological Organization (WMO), noted, “El Niño could have devastating effects on communities and economies globally. We are already witnessing disruption due to droughts and floods, and we expect these challenges to escalate as El Niño intensifies.”
She added, “This is the first time in the WMO’s 50-year history that we have initiated such extensive mobilization with national meteorological and hydrological services, who are essential in providing life-saving forecasts and services. We are out of time.”
The WMO’s updates on El Niño are regarded as the most authoritative forecasts available, derived from a consensus of climate prediction models from various global centers. The latest update, released on Thursday, confirmed that El Niño is firmly established and is expected to escalate into a “very strong event” over the coming months, with significant implications, including floods, droughts, and extreme heat persisting into 2027.
In certain regions, subsurface ocean temperatures were reported to be an extraordinary 8°C above the average during July and early August.
Chris Jaccarini from the Energy and Climate Intelligence Unit in the UK remarked, “Extreme weather patterns worldwide have led to increased food prices, disproportionately affecting the most vulnerable populations. This is impacting not only imported food but also domestic crops.”
He continued, “After enduring five heatwaves and widespread drought, British arable farmers are bracing for the worst harvest on record in 2026. Without decisive action, these conditions may only worsen. If we do not significantly reduce emissions and enhance resilience, the effects of climate change will continue to escalate, with El Niño exacerbating these trends every few years.”
