Air India Flight Makes Safe Return To Delhi Following Technical Snag As El Niño 2026 Threat Intensifies

Scientists are warning that the Pacific Ocean is rapidly warming, with a potential “monster” El Niño forming that could match the deadly 1877 event, while India also saw separate travel disruption when an Air India San Francisco-bound flight with 230 passengers returned to Delhi after a technical snag on its Boeing 777-300 ER aircraft.

“The aircraft landed safely and will now undergo a technical inspection in accordance with Air India’s safety protocols,” the airline said in a statement.

Air India said alternative arrangements were being made to help passengers continue their journey to their destination.

“In the meantime, our ground teams are providing all necessary assistance to passengers, including refreshments, hotel accommodation, or rescheduling options based on their preference,” the airline said, adding that the safety and well-being of passengers and crew remained its highest priority.

The World Meteorological Organization (WMO) now estimates a 61% chance that El Niño conditions will appear between May and July 2026. Forecast models suggest sea surface temperatures in key Pacific zones could spike around +3.0°C above normal, placing El Niño 2026 among the strongest events recorded, on top of oceans already about 1.2°C warmer than the pre-industrial era.

El Niño 2026 science, ENSO cycle and global signals

El Niño is part of the El Niño–Southern Oscillation, or ENSO, a climate system where Pacific sea surface temperatures rise or fall from average and shift weather worldwide. In an El Niño phase, trade winds weaken and warm water moves east towards South America, raising sea surface temperatures by more than +0.5°C; “super” events cross +2°C and can disturb monsoons and trigger floods together.

The opposite phase, La Niña, brings stronger trade winds and colder waters near South America, often boosting monsoon rainfall over South Asia and Australia. La Niña episodes can last one to three years and may follow El Niño as a rebound. The 2020–2023 “triple-dip” La Niña, the longest since 1974, coincided with strong Indian monsoons, severe drought in parts of the Americas and major flooding in Australia.

El Niño 2026 history, past extremes and impact scale

Four major El Niño episodes since 1877 define the scale used to judge El Niño 2026. The 1877–1878 “monster” El Niño, with a Niño‑3 anomaly near +3.5°C, coincided with famine that killed more than 50 million people across India, China, Brazil, Egypt and sub‑Saharan Africa, an estimated 3–4% of the global population at that time, equivalent to around 250 million deaths today.

The 1982–1983 event reached about +2.2°C, causing drought across Australia, India, Africa and the Andean region, while Peru and Ecuador suffered damaging floods worth about 13 billion dollars. In 1997–1998, another super El Niño peaked near +2.8°C, bringing severe drought to South and Southeast Asia, extensive coral bleaching, wildfires and about 23,000 deaths, along with roughly 45 billion dollars in losses.

From 2015 to 2016, a further super El Niño with a +2.6°C anomaly helped drive record global temperatures at that time. Around 60 million people needed humanitarian aid and mass coral bleaching hit many reefs. While the 2026 El Niño 2026 projections are slightly below the 1877 record, they still approach +3.0°C, and WMO notes that some models even edge close to the historic +3.5°C peak.

El Niño 2026 regional risks, monsoon impact and food security

A strong El Niño 2026 would not strike every region in the same way. India and much of South Asia usually see weaker June–September monsoon rains, affecting key kharif crops such as rice and pulses. Hotter conditions often accompany this rainfall deficit, raising heat stress and irrigation demand across already water-stressed districts and heightening food price risks.

Indonesia, Malaysia and the Philippines typically become drier during El Niño, especially if strength is high. Extended dryness increases peat fire risk in Borneo and Sumatra, often causing widespread haze. In Australia, especially eastern and southern regions, El Niño phases usually bring drier winters and springs and a higher bushfire threat, as seen during 1982–1983 and 1997–1998.

Different parts of Africa face contrasting El Niño 2026 impacts. East Africa often experiences heavier “short rains” from October to December, and floods can strike Kenyan highlands and Somali river basins. In contrast, southern African countries like Zimbabwe and Zambia tend to endure drought, affecting maize harvests and hydropower, with knock-on effects for electricity supply.

South America, especially Brazil and the Amazon basin, also sits in a danger zone. Central and northern Brazil often receive less wet-season rain, driving drought and forest fires. Northeast Brazil has previously suffered multi‑year drought during strong El Niño phases. Along the Pacific coast of Peru and Ecuador, warmer coastal waters raise flood risk and can disrupt fisheries.

In China and neighbouring East Asian regions, El Niño 2026 can alter rainfall timing and heat patterns. Northern China tends to see milder winters, while the Yangtze basin may receive heavier summer rain, increasing flood risk. During the 1877 event, northern China experienced one of its deadliest famines, with millions of deaths in Shanxi and Henan linked to crop failure and policy responses.

"Simultaneous multi‑year droughts similar to those in the 1870s could happen again." — Deepti Singh, Washington State University, quoted in The Washington Post, May 2026. Experts emphasise that modern forecasting gives earlier warnings, but exposure is far greater, with 8.2 billion people today compared with about 1.4 billion during the 1877 crisis.

El Niño 2026 outlook, 1877 comparison and warming oceans

The world of 2026 differs sharply from 1877, yet some dangers persist. Then, about 1.4 billion people lived on a largely pre‑industrial planet without climate forecasting, and there was no coordinated international aid system. Colonial food policies sometimes exported grain while local populations starved, worsening famine impacts in India and other territories.

Now, global population stands near 8.2 billion, and agencies such as the UN, World Food Programme and national governments can respond ahead of shocks. Advanced models from NOAA, ECMWF and Japan’s JMA provide several months of warning. However, oceans are roughly 1.2°C warmer than in 1877, so comparable Pacific anomalies can produce stronger heatwaves, heavier downpours and more intense drought.

Forecasts also suggest that 2027 could become the hottest year on record, as El Niño 2026 warmth layers onto long‑term climate change. WMO projects “nearly global dominance of above-normal temperatures” between May and July 2026, which would influence six inhabited continents. Risk assessments rank Indonesia, India, South Africa and Brazil among areas facing the greatest pressure on food, water or infrastructure.

Current estimates assign risk scores out of ten, with Indonesia at 9, India 8, South Africa 8, Brazil 8, Australia 7, East Africa 7, Peru 8, the southern United States 4 and China 5. These scores draw on historic El Niño impacts, projected 2026 strength and local vulnerability. The combination points to a busy period ahead for disaster agencies and planners.

"After a period of neutral conditions, climate models are now strongly aligned, and there is high confidence in the onset of El Niño, followed by further intensification in the months that follow." — Wilfran Moufouma Okia, Chief of Climate Prediction, World Meteorological Organization (WMO), April 2026. Officials stress that governments should already be adjusting water, crop and emergency plans.

India’s national weather office, the India Meteorological Department (IMD), and the National Disaster Management Authority (NDMA) are monitoring the developing El Niño 2026 signal, with a focus on possible monsoon shortfalls. Planning includes drought readiness, crop advisories and heatwave response. Researchers note that while early warning helps, housing, health care and irrigation access will decide how serious impacts become.

The Pacific’s sea surface temperatures are rising at their fastest rate since the 1877 event, according to analysis from the Washington Post, WMO, NOAA and peer‑reviewed work in the Journal of Climate. Although the physical signal may be stronger, today’s world also has better data, more diversified food supplies and faster aid deployment, factors that could limit the human toll compared with past disasters.

Separate from the climate outlook, Indian aviation saw an incident involving Air India on 27 May 2026. A Boeing 777-300 ER operating a Delhi–San Francisco service turned back to Indira Gandhi International Airport after staying airborne for more than eight hours, following a technical snag detected during the long-haul flight, the airline said.

The flight was carrying 230 passengers when the issue emerged en route to the United States west coast. "The aircraft landed safely and will undergo a technical inspection in line with Air India's safety standards", Air India said in a statement. The airline added that engineers would examine the aircraft before it returned to commercial service.

Air India confirmed that alternative travel options were being arranged to carry passengers onward to San Francisco. "In the mean time, our ground teams are providing all necessary assistance to the passengers, including refreshments, hotel accommodation or rescheduling as opted by them", the airline said, noting that the safety and well-being of passengers and crew remained the airline's "highest priority".

Both developments highlight different kinds of risk now under watch: the gradual build-up of a possible record El Niño 2026 with wide economic and humanitarian implications, and the more contained disruption of a long-haul flight returning safely to Delhi, where technical checks, passenger support and established safety procedures continue to guide aviation responses.
