Marine heatwaves amplify the risks of extreme weather, such as hurricanes, which can lead to devastating storm surges, infrastructure damage, and widespread physical trauma. Toxic algal blooms triggered by warm waters contaminate seafood, posing risks of paralytic and neurotoxic shellfish poisoning. Coastal communities reliant on fisheries face economic and food security challenges as fish stocks migrate to cooler waters. Beyond physical health, the psychological toll is significant, with increased eco-anxiety, chronic stress, and depression among residents whose livelihoods and cultures are tied to the sea. These risks are escalating faster than public health systems can adapt.
