El Niño's global impacts include wetter conditions in the southern U.S., drier weather in the Pacific Northwest, and severe droughts in Southeast Asia and northern Australia. South America is experiencing a mix of heavy rains in some areas and drought in others, while Africa faces both flooding and drought risks. The Atacama Desert in Chile, one of the driest places on Earth, may see rare rainfall events, potentially causing flash floods. The event is also linked to elevated risks of heatwaves, marine heatwaves, and extreme weather globally, amplified by rising baseline temperatures due to climate change.
