Scientific and Policy Preparedness for Imminent Super El Nino
Source:The Hindu ↗
Why It Matters
Understanding phenomena like El Niño and its amplified 'super' variants is crucial for UPSC aspirants because ENSO cycles directly influence India's monsoon patterns, agricultural economy, food security, and disaster management strategies.
Summary
Ecologists and scientists have called upon policymakers and the research community to closely monitor and study the imminent arrival of a 'Super' El Niño. Recognizing the severe ecological and socio-economic risks—such as intense droughts, catastrophic floods, crop failures, and coral bleaching—experts emphasize the need for robust early-warning systems and proactive adaptation frameworks to manage climate extremes.
Key Points
- Ecologists and climate scientists are urging policymakers to study and prepare for an imminent 'Super' El Niño event.
- Super El Niños can trigger severe global consequences, including extreme weather patterns, droughts, floods, and severe heatwaves.
- The phenomenon heavily impacts agricultural productivity, water security, and ecosystem stability (such as coral reefs and forests).
- Proactive scientific modeling and policy preparedness are emphasized to mitigate socio-economic and ecological damage.
Prelims Trap
El Niño is solely an atmospheric wind pattern change across the Indian Ocean basin.
Aspirants often confuse El Niño with atmospheric pressure swings alone; it is fundamentally an ocean-atmosphere coupled phenomenon involving sea surface temperature anomalies in the central/eastern tropical Pacific.
Static Concepts Connected
What are the key oceanic and atmospheric indicators used to define an El Niño event?
- SST Warming: SST Anomalies: Abnormal warming of sea surface temperatures in the central and eastern tropical Pacific Ocean (Nino 3.4 region).
- Pressure Swing: SOI Shift: A sustained drop in the Southern Oscillation Index, reflecting weakened trade winds across the Pacific.
- Circulation Shift: Walker Circulation: The normal Walker circulation cell weakens or reverses, shifting rainfall patterns eastward.
Cross-Topic Patterns
El Niño + Agricultural Food Security & Inflation
El Niño-induced agricultural distress and food inflation directly trigger proactive food security interventions, MSP adjustments, and buffer stock management by the government.
Climate Extremes + Disaster Management & Fiscal Federalism
Severe droughts and floods linked to climate anomalies strain state disaster relief funds (SDRF/NDRF) and require climate-resilient rural livelihood planning under MGNREGA.
El Niño impact on Indian monsoon + agricultural output + inflation is a recurring multi-statement perennial candidate.

With reference to 'Indian Ocean Dipole (IOD)' sometimes mentioned in the news while forecasting Indian monsoon, which of the following statements is/are correct? 1. IOD phenomenon is characterised by a difference in sea surface temperature between tropical Western Indian Ocean and tropical Eastern Pacific Ocean. 2. An IOD phenomenon can influence an El Nino's impact on the monsoon. Select the correct answer using the code given below:

La Nina is suspected to have caused recent floods in Australia. How is La Nina different from El Nino? 1. La Nina is characterised by unusually cold ocean temperature in equatorial Indian Ocean whereas El Nino is characterised by unusually warm ocean temperature in the equatorial Pacific Ocean. 2. El Nino has adverse effect on south-west monsoon of India, but La Nina has no effect on monsoon climate. Which of the statements given above is/are correct?

The World Bank warned that India could become one of the first places where wet-bulb temperatures routinely exceed 35 °C. Which of the following statements best reflect(s) the implication of the above-said report? I. Peninsular India will most likely suffer from flooding, tropical cyclones and droughts. II. The survival of animals including humans will be affected as shedding of their body heat through perspiration becomes difficult. Select the correct answer using the code given below.
