A supersized El Niño already heating the planet may become the strongest such weather pattern in at least a millennium, and its consequences are expected to extend far beyond the Pacific Ocean. The World Food Programme has warned that 50 million people are likely to be pushed into acute hunger, while researchers estimate that the extra heat from El Niño alone could cause the deaths of 450,000 people by February, from Nigeria and Indonesia to the United States.
The weather pattern, which occurs roughly every two to seven years, has already pushed Pacific Ocean temperatures past the previous record, and its peak is still ahead. Scientists describe the event in unusually stark terms, calling it a «Godzilla-level» El Niño. The result will be a massive release of heat into an atmosphere already warmed by the human-caused climate crisis, making next year almost certain to become the hottest on record globally, breaking this year's record.
The death toll from the heat itself is only part of the picture. The same phenomenon is expected to drive wildfires, droughts, and floods that will claim additional lives and destroy crops and livelihoods. Those impacts will compound the damage already being caused by global heating, creating conditions in which food systems, public health, and emergency services in vulnerable regions are stretched simultaneously.
The warnings carry particular weight because they come from eminent scientists rather than advocacy groups. Their assessments suggest that the combined effect of a natural climate cycle and human-driven warming is not simply additive but potentially catastrophic. The heat trapped by greenhouse gas emissions raises the baseline from which El Niño operates, so each event now arrives in an atmosphere less able to absorb shocks without widespread suffering.
The World Food Programme's projection of 50 million people falling into acute hunger reflects the scale of the disruption expected to food production and distribution. Acute hunger means people are unable to consume enough food to meet basic nutritional needs, often because of conflict, displacement, or sudden economic and environmental shocks. El Niño-related droughts and floods can trigger all three at once, particularly in regions where farming depends on predictable rainfall and where storage and transport infrastructure are already fragile.
Researchers estimate that the additional heat from this El Niño will cause 450,000 deaths by February. That figure spans countries as different as Nigeria, Indonesia, and the United States, underscoring that the phenomenon's health effects are not confined to the tropics. Heat stress, cardiovascular strain, respiratory illness, and waterborne disease all tend to rise during extreme temperature events, and the people most at risk are often those with the fewest resources to adapt.
The editorial framing of the crisis emphasizes that this is not merely a story about weather patterns. It is also about injustice. The countries and communities likely to suffer most from El Niño's heat, hunger, and displacement have contributed the least to the greenhouse gas emissions driving the climate crisis. That mismatch between responsibility and vulnerability is central to how the coming months are likely to be understood by scientists, humanitarian agencies, and policymakers.
With the peak of the El Niño still to come, the full extent of its effects remains uncertain. But the direction of travel is clear: more heat, more extreme weather, more hunger, and more deaths than would have occurred without human-caused warming. The warnings are grave enough that they are difficult to fully comprehend, yet they are being issued by researchers who study these systems closely. The coming year will test whether governments and international institutions can act on those warnings before the toll becomes even harder to reverse.
