El Niño 80% Likely, Will Trigger Extreme Temperature and Rainfall: WMO Warning
Summary
The World Meteorological Organization (WMO) has warned that there is an 80% probability of El Niño developing by mid-2026, posing significant risks of extreme temperatures and erratic rainfall globally.
●El Niño is a periodic warming of the central and eastern tropical Pacific Ocean that disrupts normal atmospheric circulation patterns, leading to droughts in some regions and floods in others.
●The last major El Niño event (2023–24) was the strongest on record and contributed to record-breaking global temperatures.
●For India, El Niño typically suppresses the southwest monsoon, threatening agricultural output, water security, and food inflation.
●The WMO warning underscores the compounding effect of climate change on natural climate variability, making El Niño events more intense and their consequences more severe.
●India must urgently strengthen early warning systems, drought-proofing of agriculture, and inter-ministerial climate resilience frameworks to mitigate socioeconomic disruptions.
Core Arguments
- 1
El Niño events are natural climate phenomena, but their intensification under anthropogenic climate change represents a compounding risk that demands integrated policy responses beyond traditional disaster management frameworks.
- 2
India's agricultural economy, which supports nearly 45% of the workforce, is acutely vulnerable to El Niño-induced monsoon deficits; historical data shows that major drought years (1987, 2002, 2009, 2023) coincide with El Niño events, causing GDP contractions and food inflation spikes.
- 3
The WMO's 80% probability forecast reflects advances in seasonal climate prediction, yet India's translation of such forecasts into actionable agricultural advisories, water reservoir management, and drought contingency plans remains institutionally fragmented.
- 4
Climate change is altering the baseline upon which El Niño operates — superimposed warming means even moderate El Niño events now produce record temperatures, threatening human health, energy demand, and ecosystem stability simultaneously.
- 5
India's commitments under the Paris Agreement and its National Action Plan on Climate Change (NAPCC) must be operationalized through sub-national climate resilience plans that specifically account for ENSO variability, integrating meteorological forecasting with economic planning.
Dimensional Angles
Environmental
El Niño's 80% probability forecast signals a convergence of natural climate variability and anthropogenic warming that threatens ecosystems globally. Coral bleaching events, forest fires, and glacial melt accelerate during El Niño phases. India's Western Ghats biodiversity hotspot and Himalayan glaciers face compounded stress. The WMO warning reinforces the urgency of ecosystem-based adaptation strategies, including restoration of wetlands and forests that buffer hydrological extremes, as part of India's broader climate resilience architecture.
Economic
El Niño-driven monsoon deficits directly impact India's kharif crop output, particularly rice, pulses, and oilseeds, triggering food inflation and rural income shocks. The 2023 El Niño contributed to tomato and vegetable price spikes exceeding 200%. Beyond agriculture, hydropower generation declines, industrial water use is constrained, and rural demand for FMCG goods contracts. Fiscal pressures mount as the government deploys MGNREGS, crop insurance payouts, and food subsidy expansions — underscoring El Niño's macroeconomic transmission channels.
Governance
India's institutional response to El Niño forecasts involves multiple agencies — IMD, NDMA, Ministry of Agriculture, state governments — but coordination gaps persist. The National Contingency Action Plan for Agriculture provides a framework, but its implementation varies across states. Strengthening the District Disaster Management Authority's capacity to translate seasonal forecasts into local agricultural and water management decisions is critical. The WMO warning is an opportunity to stress-test India's early warning-to-action pipeline and identify institutional bottlenecks before the monsoon season peaks.
International Relations
El Niño is a global phenomenon with asymmetric regional impacts — while India faces drought risks, East Africa and South America face floods, and Australia experiences severe bushfires. This creates opportunities for South-South climate cooperation, shared early warning data, and coordinated humanitarian preparedness. India's leadership in the Coalition for Disaster Resilient Infrastructure (CDRI) and its voice in UNFCCC negotiations gain added relevance when it can demonstrate proactive domestic El Niño preparedness as a model for developing nations facing similar vulnerabilities.
Value-Adds for Answers
- ◆
Data: The 2023–24 El Niño was the strongest on record; global average temperatures in 2024 exceeded 1.5°C above pre-industrial levels for the first time, with El Niño contributing approximately 0.2°C of additional warming above the climate change baseline.
- ◆
Concept: The Walker Circulation is the key atmospheric mechanism linking Pacific SST anomalies to Indian monsoon variability — El Niño weakens it, reducing moisture transport; La Niña strengthens it, enhancing monsoon rainfall. Understanding this mechanism is essential for UPSC Geography and Environment questions.
- ◆
Comparison: India's 2009 El Niño year saw monsoon rainfall at 77% of the Long Period Average (LPA), causing a 6.6% decline in agricultural GDP. In contrast, the 2019 El Niño was partially offset by a strong positive IOD, resulting in above-normal monsoon rainfall — illustrating how multiple climate indices interact.
- ◆
Quote: WMO Secretary-General Celeste Saulo stated: 'El Niño and La Niña are natural climate phenomena, but climate change is supercharging their impacts, leading to more extreme heat, more intense rainfall and drought' — directly linking ENSO variability to anthropogenic climate change for policy purposes.
