CURRENT AFFAIRS | 11 JULY 2026
The US National Oceanic and Atmospheric Administration (NOAA) has warned that the El Nino now building in the Pacific could become one of the strongest since 1950 — with heavy implications for India’s monsoon, food output and heat.
El Nino and La Nina are the two opposite phases of the El Nino-Southern Oscillation (ENSO), a coupled ocean-atmosphere interaction in the tropical Pacific. An El Nino is declared when sea-surface temperatures in the Nino 3.4 region run at least 0.5 degrees C above average; it is classed as “strong” once the anomaly exceeds 2 degrees C. The current anomaly is already around 1.2 degrees C, and NOAA’s monthly bulletin puts an 81% probability on a strong event during October-December 2026, with a good chance it lingers into 2027.
Why this matters for India is well documented: El Nino years are strongly associated with a weak or deficient southwest monsoon, drought and heatwaves. Roughly 90% of India’s driest years have coincided with El Nino conditions. The mechanism is the warming of the central and eastern Pacific, which disrupts the Walker circulation that normally strengthens monsoon rainfall over the subcontinent.
The comparison point is the 2015-16 “Godzilla” El Nino, one of the strongest on record. If the 2026 event matches or exceeds it, the pressure on agriculture, water reservoirs, power demand and food inflation could be severe. India’s monitoring is led by the IMD and the Indian Institute of Tropical Meteorology (IITM) Pune, where climate scientist Roxy Mathew Koll and colleagues track ENSO-monsoon linkages. For now, the message is one of watchful preparation rather than panic.
🏛️ Constitutional / Legal Framework
- ENSO: El Nino-Southern Oscillation — El Nino (warm) and La Nina (cool) phases of a Pacific ocean-atmosphere system.
- Nino 3.4 threshold: +0.5 degrees C for onset; beyond +2 degrees C for a “strong/super” El Nino.
- NOAA: US National Oceanic and Atmospheric Administration — issues the monthly ENSO bulletin.
- Indian monitoring: IMD and IITM Pune (Roxy Mathew Koll) track monsoon impacts.
⚖️ Why This Matters for CLAT
Environment and climate GK recur every year. Lock in the definitions (ENSO, El Nino vs La Nina), the temperature thresholds, and the India-specific monsoon linkage. Assertion-reason questions love the cause-effect chain: Pacific warming to weakened Walker circulation to deficient monsoon — a clean logical structure the exam rewards.
📌 Key Facts
| Warned by | NOAA (monthly ENSO bulletin) |
| Strength outlook | 81% chance of strong El Nino, Oct-Dec 2026 |
| Onset threshold | +0.5 degrees C in Nino 3.4 region |
| Current anomaly | ~1.2 degrees C (strong is beyond 2 degrees C) |
| Last super event | 2015-16 “Godzilla” |
| India link | ~90% of driest years were El Nino years |
| Monitored by | IMD, IITM Pune (Roxy Mathew Koll) |
🧠 Memory Hook
“El Nino = El No-Rain.” Threshold ladder: 0.5 = on, 2.0 = strong. Godzilla = 2015-16.
