West Palm Beach

South Florida beaches faced a sargassum assault this summer that some scientists believe is part of the largest spread of the nomadic marine weed on record, and one that could continue through September.

Heavy mats of seaweed are washing up on South Florida beaches, creating thick barriers to the ocean.

Cold temperatures have started the Fall of the Iguanas and the immobilization of sea turtles, whose bodies have a hard time adjusting to the change in water temperature.

'Frozen,' or cold-stunned, green iguanas have been falling out of trees across South Florida as record-breaking cold temperatures persist. These are an invasive species and the FWC issued a new executive order allowing people to remove the cold-stunned creatures without a permit and bring them directly to outlined FWC offices.
