Climate Shift Upends Atlantic Seaweed: One Massive Patch Grows as Another Vanishes
  • A significant shift in the Atlantic Ocean's seaweed patterns has been observed, with record-breaking blooms of yellowish-brown sargassum along the Equator, while a centuries-old patch further north is disappearing. This phenomenon has led to increased beach pollution and environmental concerns, particularly in regions like Cancun, Mexico, where cleanup efforts are being undertaken by the Mexican National Guard.
  • The implications of these changes are profound, as the growth of sargassum can disrupt marine ecosystems, impact tourism, and challenge local economies dependent on clean beaches. The disappearance of older patches raises questions about the long-term health of the Atlantic marine environment.
