Marine heatwaves fuel storms, toxic algae and mental health crisis in coastal communities

Researchers warn that marine heatwaves are a growing threat to human health, not just to coral reefs and fisheries. Unusually hot oceans can fuel stronger storms, trigger harmful algal blooms and reduce seafood supplies, disrupting the livelihoods of coastal communities. The phenomenon is also linked to anxiety, grief and depression among people who depend on the sea.
