WMO Warns of Intensifying El Niño Phenomenon
Key Points
The World Meteorological Organization (WMO) has issued a warning about the intensifying El Niño phenomenon, which could have profound impacts on global climate and food security. This is crucial for UPSC aspirants, particularly for GS Paper 1 and GS Paper 3, as it relates to climate change and agricultural issues. Last Updated: 05-09-2026
Key Facts About El Niño
- El Niño is a naturally occurring climate phenomenon characterized by the abnormal warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean.
- It results from changes in ocean-atmosphere interactions, including weakening trade winds, and typically occurs every 2 to 7 years.
- The ongoing El Niño is projected to reach the “very strong” category, with Pacific Ocean temperatures exceeding 2°C above normal.
- A strong El Niño can disrupt global climate patterns, increasing the risk of droughts, floods, storms, and typhoons.
- It can adversely affect agriculture, food security, water availability, and energy systems due to rainfall variability.
- The strong 2023-24 El Niño is expected to lead to 2024 becoming the warmest year on record.
- El Niño can influence the Indian summer monsoon, often correlating with below-normal rainfall.
Global Climate Implications
El Niño's intensification has macro-level significance as it can alter global climate patterns, impacting economic and strategic goals. It can lead to increased global temperatures, with the 2023-24 El Niño potentially making 2024 the warmest year on record. Comparisons with past events highlight the need for international cooperation in climate resilience.
UPSC Relevance
For GS Paper 1, El Niño is relevant under climate change and its effects. In GS Paper 3, it connects to agriculture, food security, and disaster management. Prelims questions could focus on the definition and effects of El Niño, while Mains could explore its impact on agriculture and climate policy. It also links to essay topics on environmental challenges.
