August 2026 marked a pivotal month for climatologists. Forecasts from all leading models, ranging from the American NOAA to the European ECMWF, point to a single conclusion: the current El Niño is developing at a pace unprecedented even during the record events of 1997–1998 and 2015–2016.
Models predict that by the end of 2026, this phenomenon could surpass even the most powerful event in the history of instrumental observations—the 1877–1878 El Niño.
The physics of El Niño are straightforward, but its consequences are extensive. The phenomenon begins when warm waters in the western Pacific start to shift eastward, suppressing the usual upwelling—a flow of cold, nutrient-rich deep waters along the coasts of South America. This disrupts global atmospheric circulations: some regions experience torrential rains, while others face droughts. The core of the 2026 El Niño has already progressed through its peak phase at a speed that has outpaced the development of even the 1997 and 2015 events by several months.
What makes 2026 particularly special? It is because this super-strong El Niño coincides with a period when the planet's baseline temperatures are already at historically unprecedented levels. While the world was a full one and a half degrees Celsius cooler in 1878 than it is today, the current phenomenon is unfolding against a backdrop of an overheated ocean. This creates an exponential effect: more energy in the system translates to more extreme weather conditions, more severe droughts, and more devastating downpours.
On the ground, this manifests in concrete statistics of natural disasters. In Australia and Indonesia, wildfires have reached record scales—partly due to the positive Indian Ocean Dipole, which is also intensifying concurrently with El Niño. In Peru and Ecuador, floods and landslides are destroying infrastructure. Fish stocks off the coast of Peru, which underpin one of the world's most important fishing fleets, are declining by tens of percent because the cold water that typically rises to the surface remains in the depths.
Climatologists have long debated whether El Niño is becoming more intense due to anthropogenic climate change, or if global warming simply creates conditions under which natural fluctuations become more powerful. New research suggests the answer is likely both. An overheated ocean amplifies El Niño peaks, enabling them to reach extreme values. Thus, climate change acts not as an independent factor, but as an amplifier of existing oscillations.
When a giant heat wave forms in the western Pacific, its effects do not remain localized. They spread globally, reflected in shifted wind patterns and atmospheric circulation changes. The result is altered precipitation patterns from Africa to South America, and from Asia to Australia. This could mean drought in areas that typically receive rainfall, or unexpected downpours in deserts. Tropical forests, coral reefs, and bird migration routes—all come under simultaneous pressure.
History serves as a reminder of the importance of monitoring. The 1877–1878 event occurred during an era when meteorological networks were primitive and marine observations were scarce. Today, we possess satellites, ocean buoys, and supercomputers that enable real-time tracking of El Niño's development.
International observation programs, such as TOGA (Tropical Ocean-Global Atmosphere), launched back in 1983, provide us with the ability to understand and forecast these catastrophic events. This represents a window of knowledge and early warning that humanity lacked in 1876.
