The world is entering a prolonged period of climatic stress. The United States National Oceanic and Atmospheric Administration has officially confirmed that El Niño conditions are now established, and its forecasters warn the phenomenon could reach exceptional intensity in the coming months, altering rainfall, temperature and wind patterns across the planet. Meteorologists in Bogotá are already bracing for a “strong or very strong” event that may extend as far as 2027, piling pressure on governments from New Delhi to Washington to prepare for disruption on multiple fronts.

In South Asia, the immediate concern is respiratory health. The extreme heat associated with El Niño accelerates the formation of ground-level ozone and traps airborne particulates, irritating airways and thickening mucus. Public health specialists in India caution that dehydration further compromises the lungs’ ability to expel irritants, leaving those with asthma and chronic obstructive pulmonary disease acutely vulnerable. Simple measures—rigorous hydration, monitoring of air-quality indices and mask-wearing outdoors—are being urged as heatwaves become more frequent and intense.

Viewed from the Americas, the threat is equally stark but plays out through economic and political channels. In the United States, analysts warn that a super El Niño could slash crop yields in key foreign-supply regions, jeopardising imports of fresh fruits and vegetables at a time when grocery inflation already runs at nearly three per cent and overall food prices are projected to climb well above that. Half a continent away, Colombia faces a more fundamental reckoning. A presidential run-off has crystallised a bitter debate over energy policy: one camp advocates carefully regulated fracking pilots as a bridge fuel, while the other demands an immediate pivot away from fossil fuels and towards renewable sources, a dispute that El Niño’s impact on hydroelectric reservoirs has made urgent. Low water levels not only threaten power generation but compound the fiscal strain on a government already grappling with a deteriorating health system and surging infrastructure demands.

The risks are not confined to policy-makers and farmers. With the northern hemisphere’s summer travel season coinciding with the onset of extreme heat, medical experts are urging the public to recognise the signs of heat illness—cramps, exhaustion and the potentially fatal progression to heat stroke. They advocate the same methodical preparation that people routinely apply to winter journeys, noting that the combination of high temperatures, dry air and gusting winds can render even short outdoor exposures dangerous.

As El Niño intensifies, the interconnected nature of these threats becomes clearer. A failure of rains in one region raises commodity prices in another; a heatwave that overwhelms hospitals in India echoes the economic shocks that could destabilise policymaking in Latin America. The cautionary lesson from Bogotá to New York is that this is not merely a weather event but a stress test for public health systems, food chains and political settlements—one that, if forecasts hold, could endure far longer than a single scorching summer.
