The anticipated record-breaking El Niño could have profound global impacts. In the U.S., southern regions may face increased flooding, while northern areas could experience heatwaves and drier conditions. Internationally, droughts and wildfire risks are expected in Indonesia, Australia, and parts of Africa, while South America and East Africa may see heavy rainfall. The event could worsen food insecurity and disrupt energy supply chains, particularly in vulnerable regions. Scientists warn that the combination of El Niño and ongoing climate change could lead to unprecedented weather extremes.
