Jellyfish stings are up this year off Georgia’s coast. 10,000 people have been treated so far, up from 7,500 last year. But that doesn’t mean there are more jellyfish in Georgia waters. University of Georgia marine scientist John Crawford says data show there are more jellyfish globally because of warmer waters, a decrease in predators, and changes to ocean chemistry. But he says a surge in stings has to do with people.
