UN Secretary-General António Guterres on Friday, 1 August issued an urgent call for worldwide action to combat extreme heat, warning that the worst effects of El Niño are still ahead. Speaking at a press encounter in New York, Guterres cited a fresh update on El Niño forecasts released by the World Meteorological Organization (WMO), describing current conditions as merely a prelude to greater danger.

El Niño Is Strengthening, Warns Guterres

According to the WMO outlook, this summer's extremes — record-shattering heat domes, catastrophic wildfires, thousands of deaths in scorching conditions, and record-high global sea-surface temperatures — represent only the opening act of a more severe crisis. Guterres stated that Pacific waters driving El Niño have never been this warm this early in the phenomenon's cycle, and temperatures continue to climb. The WMO outlook projects that through October, nearly every land area on Earth is expected to record above-normal temperatures.

Notably, El Niño's reach extends well beyond heat. India's monsoon is already running well below average, according to Guterres, while hotter and drier conditions are forecast across Central America, the Caribbean, parts of South America, South Asia, the Southwest Pacific, Europe, and Africa.

Four-Point Action Plan

The UN chief outlined action on four fronts: protect people before heat becomes deadlier; make workplaces safer; build and retrofit infrastructure for rising temperatures; and halt the practices fuelling the climate crisis. He called for every city and country to establish heat-health action plans, early warning systems, and public health measures that reach communities in time. Guterres also stressed that access to sustainable cooling must expand urgently and equitably.

On labour protections, he urged governments and employers to set enforceable heat standards, adjust working hours, and safeguard incomes when work must stop due to dangerous temperatures. He added that protection from extreme heat must be built into the design of cities, homes, schools, and hospitals, and incorporated into every public plan and budget.

Fossil Fuels in the Crosshairs

Guterres issued a pointed warning on new fossil fuel development, arguing that every new project approved today makes tomorrow's heatwaves more dangerous and the world less secure. 'The verdict is clear: the climate crisis is in overdrive,' he said. He added: 'Today's findings show that extreme heat is not a future threat. It is here. It is becoming more dangerous. And unless we act — to protect people and tackle the root cause of the crisis — it will become deadlier still. The warm-up act is over. We cannot afford to wait for the main event.'

What This Means for India and South Asia

South Asia faces a compounded risk: El Niño is simultaneously driving above-normal temperatures and suppressing monsoon rainfall, threatening agricultural output and water security. India has experienced repeated heat emergencies in recent years, and the WMO's projection of sustained above-normal temperatures through October raises concern for public health systems already under strain. This comes amid a broader pattern of worsening climate extremes that scientists have consistently linked to rising greenhouse gas concentrations.

The international community's response to Guterres's call — and how quickly nations translate heat-action plans from policy to implementation — will determine whether lives are spared in the months ahead.
