How El Niño shapes the world’s weather trends
Summary
Science Friday explores the potential for a "super El Niño" this year with NOAA research scientist Dr. Dylan Amaya. He explains how warming Pacific waters shift global weather patterns, bringing wetter conditions to the U.S. Southwest but exacerbating marine heat waves. The discussion covers impacts on ecosystems, such as coral bleaching, and clarifies that while El Niño is certain, its intensity remains uncertain until fall.
