LONDON, June 4, 2026 — Scientists have issued a fresh warning about the possible arrival of a “Super El Niño,” saying there is a 90 percent likelihood that the powerful climate phenomenon will develop in the coming months and intensify extreme weather conditions worldwide.
According to reports citing climate experts, the event could trigger severe heatwaves in many countries, while others may experience unusually heavy rainfall and flooding. Scientists believe the impacts could persist through November.
The warning comes as the world continues to face record-breaking temperatures and increasingly frequent natural disasters linked to climate change. Experts caution that the emergence of a Super El Niño could further worsen these conditions.
United Nations Secretary-General Antonio Guterres stressed the seriousness of the threat, saying that scientific evidence points to a high probability of El Niño developing in the near future.
The science is clear. There is a 90 percent chance that El Niño will arrive in the coming months. The world must treat this as an urgent weather warning,” Guterres said.
He warned that El Niño would add further pressure to an already warming planet, amplifying climate-related disasters across borders with increasingly destructive force.
Guterres also emphasized the need for stronger climate action, including reducing dependence on fossil fuels, expanding renewable energy use, protecting vulnerable communities, and ensuring universal access to early warning systems.
Scientists have begun raising concerns about the potential humanitarian and economic consequences of the phenomenon. They warn that El Niño could disrupt global food production, contribute to rising food prices, and increase the risk of severe droughts and devastating floods in different regions of the world.
Climate experts also suggest that 2026 could set a new global temperature record if the expected El Niño event reaches full strength.
