El Nino strengthened rapidly, firmly established, may intensify further: WMO

The World Meteorological Organization (WMO), the United Nations' authoritative voice on weather, climate, and water resources, has confirmed that the El Niño phenomenon has rapidly strengthened and is now firmly established across the tropical Pacific. This declaration, made in mid-2024, carries profound implications for global climate systems, with near certainty that the event will persist until February 2027 and peak by the end of 2024 — though its exact magnitude remains uncertain. To understand the gravity of this announcement, one must first grasp what El Niño truly is: a naturally occurring climate pattern characterized by the unusual warming of surface waters in the central and eastern equatorial Pacific Ocean, disrupting normal atmospheric circulation. It is the warm phase of the El Niño-Southern Oscillation (ENSO) cycle, alternating with La Niña (cool phase) and neutral conditions. Historically, El Niño events occur every 2–7 years and typically last 9–12 months, but this current episode has shown accelerated development, raising concerns among climate scientists. The key stakeholders involved include the WMO, national meteorological agencies like the India Meteorological Department (IMD), agricultural ministries, disaster management authorities, and international bodies such as the FAO and UNDP. For India, the stakes are exceptionally high. The Indian monsoon, which delivers over 70% of the country's annual rainfall, is highly sensitive to ENSO phases. Past strong El Niño years — such as 1982–83, 1997–98, 2009–10, and 2015–16 — have frequently coincided with below-normal monsoon rainfall, droughts, and agricultural distress. The 2015–16 event, one of the strongest on record, led to a 14% rainfall deficit and severe water crises in Maharashtra, Telangana, and Bundelkhand. With the current El Niño expected to peak in late 2024, the 2024 southwest monsoon (June–September) and the subsequent rabi season are under close watch. Constitutionally, while there is no specific article on climate phenomena, the responsibility for disaster management and agriculture falls under the State List (Entry 14, 18, 28) and Concurrent List (Entry 20A for disaster management inserted by the 42nd Amendment, 1976). The Disaster Management Act, 2005, establishes the National Disaster Management Authority (NDMA) under the Prime Minister, enabling coordinated response. Additionally, Article 48A (Directive Principles) mandates the State to protect and improve the environment, and Article 51A(g) imposes a fundamental duty on citizens to protect natural resources. The National Action Plan on Climate Change (NAPCC), 2008, and State Action Plans further guide adaptation. The Pradhan Mantri Fasal Bima Yojana (PMFBY) and the recently restructured Weather-Based Crop Insurance Scheme (WBCIS) are critical policy instruments to cushion farmers against climate-induced losses. Economically, a weak monsoon can reduce GDP growth by 0.2–0.5 percentage points, spike food inflation, and strain rural demand — impacting sectors from FMCG to automobiles. Politically, droughts often trigger farmer protests and influence electoral outcomes in agrarian states. Internationally, India's role in the International Solar Alliance (ISA) and Coalition for Disaster Resilient Infrastructure (CDRI) positions it as a leader in climate resilience. The WMO's forecast also underscores the urgency of implementing the Sendai Framework for Disaster Risk Reduction (2015–2030) and achieving SDG 13 (Climate Action). Looking ahead, the uncertainty in magnitude means India must prepare for multiple scenarios. The IMD's dynamic and statistical models, coupled with real-time data from the Indian National Centre for Ocean Information Services (INCOIS) and buoy networks like RAMA and TAO/TRITON, will be vital. Long-term, climate change is increasing the frequency and intensity of extreme ENSO events, as noted in IPCC AR6. Thus, investing in climate-resilient agriculture, groundwater recharge (Atal Bhujal Yojana), and early warning systems (Common Alerting Protocol) is not optional — it is imperative for food security and sustainable development.
