California faces highest shark numbers in years as great whites head north

California is experiencing an unusual surge in shark populations, particularly juvenile great whites, as they migrate north from Mexico's warmer waters due to the El Niño climate phenomenon. While encounters with humans are still rare, the increased presence of these marine predators has heightened awareness and concern among coastal communities and surfers. This shift underscores broader environmental changes and highlights the need for ongoing monitoring and conservation efforts to protect both marine life and public safety.
