Hurricanes can trigger toxic spills. Many Mass. chemical sites lack a key safeguard

Experts say climate change is increasing the risk of a “double disaster” — a large-scale chemical spill caused by extreme weather. Massachusetts is especially vulnerable, as a coastal state with industrial ports.

WBUR's senior investigative reporter Patrick Madden took a closer look at this risk in New Bedford, a city with a high concentration of warehouses that use chemicals for cold storage in the fishing industry. He joined Radio Boston to discuss his reporting.
