The world’s leading weather organization is sounding the alarm about this year’s super El Niño, issuing its most certain forecast in the history of the organization.
asserted
organization → lead → organization
In an update issued early Thursday, the World Meteorological Organization predicted a “nearly 100% likelihood” that the El Niño will last through February.
asserted
Niño → issue → February
The strong language from the WMO—the UN’s weather and climate agency—underlies just how historic this El Niño is shaping up to be.
asserted
Niño → underlie → WMO
“This is the first time that a WMO El Niño/La Niña Update has been so unequivocal,” the agency says, noting that certainty reflects “the strong agreement within WMO’s extensive network.”
El Niño is a naturally occurring weather phenomenon defined by warmer-than-normal ocean temperatures in the eastern tropical Pacific, a pattern that disrupts weather patterns around the world.

Scientists have been warning since the start of the year that a particularly strong El Niño was set to develop.
asserted
Niño → warn → year
The latest forecasts indicate it will be the strongest on record by a wide margin, and impacts are already being felt throughout the world—and they’re likely to intensify in the coming months.
asserted
they → indicate → months
“El Niño is being supersized before our eyes,” UN Secretary-General António Guterres said in a statement.
asserted
Guterres → supersize → statement
“The science leaves no room for doubt: The planet is in uncharted waters, and those waters are heating up.
asserted
waters → leave → waters
Sea surface temperatures are rising, temperatures keep climbing, and the world is in the danger zone of extreme weather.”
asserted
world → rise → weather
In addition to affecting regional weather, El Niño also tends to bump up the global average temperature by roughly 0.1 to 0.2 degrees Celsius (0.2 to 0.4 degrees Fahrenheit) by releasing heat into the atmosphere.
asserted
Niño → affect → atmosphere
But this year’s iteration could provide an even bigger boost.
uncertain
iteration → provide → boost
The intensity of this El Niño means this year is likely to be the hottest on record; because it takes a while for the added heat to work through the climate system, 2027 is forecast to be even hotter.
asserted
2027 → mean → system
This extra warming is a red alert when compounded on top of the warming caused by manmade climate change.
asserted
warming → compound → change
The UN warned in a separate report this week that the world will likely cross 1.5 degrees C of warming over the next few years.
asserted
world → warn → years
Daniel Swain, a climate scientist with the University of California Agriculture and Natural Resources research network, says this El Niño will be so big, “with consequences that are so large, I’m not sure we fully understand them.”
asserted
we → say → them
The intensity of the El Niño, Swain says, means that it may cause unexpected and extreme weather, and he cautions against making certain predictions about what, exactly, is going to happen over the next year.
uncertain
what → say → year
But the impacts, he says, will almost certainly be massive.

“This is probably one of the larger, if not the largest, climate events—aside from long-term warming, which really isn’t a singular event—that anybody alive is potentially ever experiencing,” he says.
asserted
he → experience → that
“That’s a very big deal.
asserted
That → ’ → ?
And I think there’s certainly going to be dramatic outcomes from this.
asserted
I → think → this
While the El Niño won’t reach its full strength for another few months, the world has already seen some impacts: The US just lived through the hottest summer on record, and the heat was almost certainly juiced up by El Niño.
asserted
heat → reach → Niño
Regions that are typically dry during El Niño have also seen drought emerge.
asserted
drought → see → Niño
In Sudan, low water levels in the Nile are exacerbating a yearslong hunger crisis, while Puerto Rico has turned to water rationing due to dry conditions and infrastructure failures.
asserted
Rico → exacerbate → conditions
Fisheries in the eastern Pacific have also been thrown into disarray by the hotter-than-normal waters there.
asserted
Fisheries → throw → waters
“The race now is between rising risks and our commitment to take climate action and protect people,” Guterres said in the release.
asserted
Guterres → rise → release
“We must win that race.”
