Florida's Gulf Coast Battles Deadly And Smelly Red Tide (npr.org)

Greg Allen, writing for NPR: Florida this week declared a state of emergency because of a slow-moving natural disaster -- red tide. Red tide is toxic algae that have persisted off Florida's Gulf Coast for nearly a year. In recent weeks, the algae bloom has worsened, killing fish, turtles and dolphins and discouraging tourism on some of the state's most beautiful beaches.

Scores of dead fish were visible on the shore of Manatee Beach on a recent morning. There was a smell from the fish, but something more -- an acrid smell that can make you cough. Mary Vanswol, who was at the beach with her husband, James, said, "Uh, the smell is terrible. And it's affecting my lungs. I'm coughing, not so much him, but I am. It's just sad to see all the dead fish." The Vanswols live nearby and usually go swimming. But not today. After getting a look at the dead fish and the murky, slightly reddish-hued water, Mary Vanswols said they were leaving. "I wouldn't even walk along the edge of it. I just don't think it's safe," she said.
Robert Weisberg, an oceanographer at the University of South Florida whose lab produces seasonal and short term forecasts of red tide, told Gizmodo a confluence of ocean circulation and environmental factors are likely responsible for initiating the bloom. Others experts are pointing to the potential role of human-driven nutrient pollution in helping to maintain it.

    Red tide is natural. It's also increased by runoff containing manmade fertilizers into the ocean. The "control" part is about preventing unneeded runoff, not mucking with nature.

    Yeah - the florida governor is able to control oceanic currents. These algae blooms happen. Ever hear of the Red Sea? Yeah - it's been called that since 2500BC for the same reasons as this algae bloom, well before any Republicans got your panties in a twist. Take off your hippie hat for a few seconds and try to think rationally.

    That's not what he said. Quit the hyperbole.

    True. It's also true that dumping fertilizer runoff into the ocean increases their size and duration. The issue here isn't the red tide per se -- it's how long it has lasted.

    If you bother to read TFA (the second one, which may be a bit too much to ask), you'll see that human pollution and climate change are causing this red tide to be much worse than the "natural" events of the past.

    Algae are plants. Fertilizer feeds plants. Allowing runoff from a lake heavily contaminated with fertilizer runoff to be dumped into the ocean has a predictable result. Science, baby!

    It isn't without a shred of proof, it is a documented phenomena that fertilizer runoff worsens algae blooms. It'd be impossible for it not to occur, really... the microbes are going to eat what you give 'em. The only thing at issue is whether it exacerbated this bloom, which while I believe the evidence is currently pointed to "yes" is a harder question to answer definitively, given that they occur naturally and there were potentially other affects that may have contributed more to how bad this bloom is.
