A strengthening El Nino has already broken records for intensity at its early stages and is likely to spark even more wild weather worldwide as it grows, “adding fuel to a planet already on fire”, United Nations officials have warned.
A key area of the Pacific Ocean used to measure the strength of El Nino this week reached its warmest and most intense level ever recorded for the 15th week since it formed, which is early in its lifetime, scientists at Columbia University reported.
El Nino — a natural warming of the Pacific near the equator that warps weather patterns worldwide — will not peak for several months and should last through the spring of 2027.

The World Meteorological Organisation (WMO), a UN agency, cautioned on Friday that it will likely trigger extreme heat, drought and rainfall well into next year.
“Two months ago, I warned that El Nino was arriving on our doorstep. Now it is inside the house — and turning up the heat,” United Nations secretary-general Antonio Guterres told reporters on Friday.
“We have already endured a summer of extremes — record-shattering heat domes; apocalyptic wildfires raging in Spain, France and far beyond; thousands of lives lost in the scorching conditions.”
Mr Guterres said that according to the latest science “this is only a warm-up act”, warning that as the El Nino strengthens it will be “adding fuel to a planet already on fire”.
The climate crisis is in overdrive
“We are in uncharted territory,” he said. “The climate crisis is in overdrive.”
Most computer forecast models are showing that this El Nino will probably break the all-time record for intensity when it peaks, sometime late autumn or so, but that is not guaranteed, scientists said.
It is still early in the nearly year-long life of a typical El Nino to see many direct effects yet, but they are coming, scientists said, agreeing with Mr Guterres’ warnings.
El Nino’s effects will combine with the long-term global warming from the burning of coal, oil and gas.
Columbia University climate scientist Jeffrey Shaman said: “A year from now, it’s going to be very hot in the Northern Hemisphere. And we’re going to possibly have a summer like we’ve never experienced globally.”
But before then, the strong El Nino is likely to cause changes in rainfall patterns that will bring chaotic extremes to different parts of the world in autumn and winter.
There is a strong chance of drought and wildfires in Indonesia, India and other parts of Asia, south and east Australia, chunks of South America and southern regions in Africa, the WMO warned. Other areas, including much of the United States and fire-struck southern Europe, will get above-average rain.
“This El Nino, developing against the backdrop of unprecedented ocean heat and rising temperatures, provides governments and communities with a window of opportunity to anticipate risks and act before impacts unfold,” said WMO secretary-general Celeste Saulo.
While El Nino and climate change are separate phenomena, their effects create a harmful combination — and people are not taking the connection seriously enough, Mr Guterres said.
“We hear much about record heat, drought and wildfires — but not enough about the real change that is driving these events: the accelerating climate crisis powered by fossil fuels,” Mr Guterres said.

Much of the heat from the burning of fossil fuels gets trapped in the oceans, but “during an El Nino the ocean in some sense gets to return some of the heated build-ups of global warming back to the atmosphere,” Mr Shaman said. Even though this El Nino will end, the released heat sticks around in the air, along with the higher temperatures, which will jump up again during the next El Nino, he added.
Mr Guterres called for more early warning systems and cooling systems to handle extreme heat. He said industry and governments need to make work safer, highlighting the garment industry, which has 90 million workers, most of them women.
But mostly, Mr Guterres said, “the world must stop fuelling the crisis…. more coal, oil and gas will lead to a more combustible future”.
