For one scientist, climate change in the Northeast announces itself in the abnormal appearances of warm-water fish – an abundance of mahi-mahi and unprecedented sightings in January of Gulf Stream flounder and juvenile black sea bass in shallow waters off the New England coast.
“Nobody had ever seen that before,” said Glen Gawarkiewicz, an oceanographer from the Woods Hole Oceanographic Institution in Massachusetts.
For another scientist, the phenomenon materializes in ocean temperatures, which have been rising for more than a generation, influencing coastal weather and pushing snowfall farther inland.
