Why scientists warn super El Niño Could trigger extreme weather across the world?

Scientists are warning that a rapidly intensifying El Niño could become one of the strongest on record, raising fears of extreme heatwaves, weaker monsoons and climate disruptions across the India and other parts of the world.

New Delhi: Climate scientists across the world are closely monitoring a rapidly strengthening El Niño event in the Pacific Ocean that could develop into one of the most powerful warming episodes recorded in recent history. Forecast agencies, including the National Oceanic and Atmospheric Administration, have warned that ocean temperatures are rising faster than earlier projections.

Several climate models now indicate the developing event could rival the major Super El Niño episodes of 1982-83, 1997-98 and 2015-16. Experts expect the phenomenon to intensify through the second half of 2026, with peak strength likely between October 2026 and February 2027.

According to NOAA’s Climate Prediction Center, there is now a strong possibility that El Niño conditions could become “strong or very strong” in the coming months.

What exactly is El Niño?

El Niño-Southern Oscillation, commonly known as ENSO, is a natural climate cycle linked to warming ocean temperatures in the central and eastern Pacific Ocean. During an El Niño phase, warmer waters alter global wind patterns and atmospheric circulation, influencing rainfall, storms, droughts and temperatures across many regions of the world.

Scientists classify El Niño conditions when sea surface temperatures remain at least 0.5 degrees Celsius above average for a sustained period. A “Super El Niño” generally refers to warming exceeding 2 degrees Celsius above normal.

The current warming trend has raised concern because global oceans are already experiencing unusually high temperatures due to long-term climate change.

Why India is watching closely

For India, the development carries major implications because of the country’s dependence on the southwest monsoon. Weather experts have warned that a powerful El Niño could weaken seasonal rainfall, trigger prolonged dry spells and increase the risk of heatwaves across several regions.

The India Meteorological Department has also cautioned that rainfall may become uneven, with some states experiencing drought-like conditions while others face sudden heavy downpours and flooding.

A weaker monsoon could impact agriculture, reduce crop yields and place pressure on food prices, water availability and electricity demand. Nearly half of India’s population still depends directly or indirectly on farming for income and livelihood.

Rising heatwave concerns

Scientists say El Niño events often amplify global warming by releasing additional heat from the ocean into the atmosphere. The previous El Niño event between 2023 and 2024 was linked to record-breaking global temperatures.

Experts now fear that northern, central and eastern India could face longer and more severe heatwave conditions if the current warming intensifies further.

Researchers also caution that climate change is making El Niño patterns harder to compare with historical events, increasing uncertainty around future weather extremes.

Better forecasting offers some relief

Despite growing concerns, scientists note that modern forecasting systems have improved significantly over recent decades. Governments and disaster management agencies now have months of advance warning to prepare for possible climate disruptions, reducing the risk of large-scale humanitarian crises.
