Extreme El Nino Events: Impacts, Preparedness, and Climate Change Linkages
An aspirant should be able to analyze the scientific basis of extreme El Nino events, articulate their diverse global and regional impacts, and discuss comprehensive preparedness and mitigation strategies, while also linking them to the broader context of climate change.
Understand the issue · 1/2
Why now
01The WMO's warning about the unprecedented strength of the current El Nino event highlights an immediate and significant global climate challenge. This makes understanding its scientific basis, potential impacts, and necessary preparedness measures crucial for UPSC Mains, especially in the context of climate change and disaster management.
Core issue
02The World Meteorological Organization (WMO) has warned that the current El Nino event over the tropical Pacific could be unprecedented in strength, with sea surface temperatures potentially rising to 3.8 degrees Celsius above average. This extreme El Nino is expected to peak towards the end of 2026 but its impacts, including disrupted temperature and rainfall patterns, severe droughts, heavy rainfall, and increased heat, will be felt long after. Telangana has already initiated micro-level contingency plans to address potential drinking water and electricity shortages.

WMO Statement
Use to highlight the severity and scientific consensus on the current El Nino's strength ('literally off the monitoring charts').
Projected Temperature Anomaly
Use as data point: 'sea surface temperatures in the tropical Pacific may rise to 3.8 degrees Celsius above average' to illustrate the extreme nature.
El Nino Impacts
Use as a general framework: 'severe drought to some regions, heavy rainfall and flooding to others, and increased heat across large parts of the world' for discussing diverse consequences.
Telangana's Preparedness
Use as an example of proactive state-level action: 'prepare micro level contingency plans to avert drinking water, electricity shortages' for disaster management answers.
ENSO Phases
Use to explain the cyclical nature of climate phenomena: El Nino (warming), La Nina (cooling), and neutral phase, in contrast to long-term climate change.
How UPSC has tested it
PYQ connections
Discuss global warming and mention its effects on the global climate. Explain the control measures to bring down the level of greenhouse gases which cause global warming, in the light of the Kyoto Protocol, 1997.
Connection: The question directly asks for effects of global warming on global climate, and extreme El Nino events are a critical example of such effects, often exacerbated by global warming.
Examine the factors responsible for depleting groundwater in India. What are the steps taken by the government to mitigate such depletion of groundwater?
Connection: The question asks for factors responsible for groundwater depletion, and El Nino-induced droughts are a significant climatic factor.
Explain the mechanism and occurrence of cloudburst in the context of the Indian subcontinent. Discuss two recent examples.
Connection: The question asks about the occurrence of cloudbursts, and El Nino events can significantly influence the atmospheric conditions and monsoon patterns that lead to such extreme weather phenomena in the Indian subcontin...

The World Meteorological Organization (WMO) has warned of an unprecedented El Nino event with significant global impacts. Discuss the mechanisms through which El Nino influences global weather patterns and critically analyze the preparedness strategies India needs to adopt to mitigate its adverse effects, particularly in sectors like agriculture and water resources.
Introduce El Nino, explain its mechanisms and global impacts, then detail India's preparedness strategies with examples.
Write this answerThe World Meteorological Organization (WMO) has issued a stark warning regarding an unprecedented El Nino event. In this context, critically examine the role of international organizations in addressing global climate phenomena and the challenges faced by developing countries like India in building climate resilience.
Discuss the functions of international organizations in climate governance, then analyze the specific challenges for developing nations in building resilience, with India as an example.
