Shark sightings off New York's coast are linked to climate change, scientists say

Repeated shark sightings off New York's Atlantic coastline are causing concerns this summer, especially after another sighting at Long Island's popular Jones Beach State Park on Thursday morning. Scientists say warming waters, caused by climate change, are helping to drive the sharks farther north.

Just a day before a shark was spotted at Jones Beach, a neighboring beach was closed after multiple sharks were seen about 20 yards off the coast. "Our guards spotted numerous — not just one, but numerous blacktip reef sharks," said Hempstead town supervisor Don Clavin. "These are really unique sharks…they're Caribbean sharks. They're known to come close to the shoreline in feeding areas. So the concern is obviously with swimmers."
