El Niño's impacts are expected to vary globally, with heightened risks of heatwaves, flooding, and droughts. In the U.S., the southern states may experience wetter and cooler winters, while the northern regions could see warmer-than-average conditions. The Pacific hurricane season may intensify, while the Atlantic season could see fewer storms. Globally, regions like Australia, Indonesia, and parts of Southeast Asia may face drought and heatwaves, potentially leading to wildfires and water shortages. Conversely, areas like southeastern South America and parts of Africa may experience heavier rainfall, increasing flood risks. Marine ecosystems are also at risk, with potential coral bleaching due to elevated ocean temperatures.
