A common dolphin, the most abundant cetacean in the world, surfaces from Pacific Ocean waters on July 17, 2026 off the coast of Long Beach, California, as seen from an Aquarium of the Pacific Harbor Breeze Cruise bringing visitors on a whale-watching excursion to see how warming waters off the Southern California coast are affecting marine mammals and wildlife. Surface water temperatures along the California coast are now three to four degrees C above normal, according to the US National Oceanic and Atmospheric Administration (NOAA). (Photo by Frederic J.
