UN Under-Secretary-General Tom Fletcher on Wednesday issued a stark warning at a news conference in Geneva, describing the current El Niño as a 'wrecking ball' that will deliver 'economic shocks for the global economy' and batter Asia, Latin America, Eastern and Southern Africa, and the broader Global South with extreme heat, droughts, and floods. Fletcher, whose portfolio covers humanitarian and emergency relief, called the next two weeks a 'critical window to act' before irreversible damage sets in.

Fletcher's Warning: Scope and Scale

'This El Niño is a behemoth. It is a wrecking ball. It will tear through Latin America, Eastern and Southern Africa, Asia and the Pacific with extreme heat, droughts and floods,' Fletcher said. He stressed that the consequences will not be contained to the countries in the immediate path of the weather event. 'It will create economic shocks for the global economy and drive further conflict, displacement, migration,' he added.

Fletcher announced he is writing to countries with existing disaster response capacity — part of the UN's coordinated emergency network — asking them to place that capacity on immediate standby. He also called for a 'much wider global mobilisation of solidarity, expertise and action' spanning governments, civil society, academia, and businesses.

WMO Chief Warns of Unprecedented Intensity

World Meteorological Organisation (WMO) head Celeste Saulo, who also spoke at the Geneva briefing, said the El Niño could be 'unprecedented in strength, literally off the monitoring charts' used over the past four decades. While the phenomenon is expected to peak towards the end of this year, Saulo cautioned that 'its impacts will be felt long after that.'

For Southeast Asia, Saulo warned of warmer conditions and rainfall deficits that would heighten the risk of heat exposure and place pressure on agriculture and water supplies. She also flagged increasing wildfire and smoke hazard risks already emerging across the region. A WMO bulletin from last week indicated that normal to above-normal maximum and minimum temperatures are likely over most of the southern part of South Asia through the rest of the year. Notably, neither Fletcher nor Saulo provided country-specific impact projections at the briefing.

India's Role in Regional Disaster Preparedness

India has assumed a growing international role in weather disaster forecasting and post-disaster relief coordination. New Delhi's India–UN Development Partnership Fund has sponsored projects for early warning systems and disaster risk reduction across seven Pacific Island countries.

Additionally, India, alongside fellow Quad members — the US, Japan, and Australia — operates Humanitarian Assistance and Disaster Relief (HADR) programmes specifically designed for the Indo-Pacific region, which faces some of the most acute El Niño-related exposure.

The Stakes: Economic and Humanitarian

The UN's framing of El Niño as an economic threat — not merely a weather event — underscores the cascading second-order effects that climate disruptions now carry. Crop failures driven by droughts can trigger food price inflation globally; flooding displaces populations and disrupts supply chains; extreme heat suppresses agricultural and industrial productivity. This comes amid an already fragile global economic outlook, with several major economies contending with elevated debt and sluggish growth.

'It would be an extraordinary failure to see this crisis coming, to hear the predictions from the experts, and yet still squander the opportunity to protect people in its path,' Fletcher said, framing the window for prevention as narrow and rapidly closing. As the El Niño moves toward its peak, the adequacy — and speed — of the global response will determine how much of the projected damage can be averted.
