Impact of climate change on tropical fisheries would create ripples across the world

Seafood is the most highly traded food commodity globally, with tropical zone marine fisheries contributing more than 50% of the global fish catch, an average of $USD 96 billion annually. Available scientific evidence consistently shows that tropical marine habitats, fish stocks and fisheries are most vulnerable to oceanic changes associated with climate change. However, telecoupling, or linkages between distant human-natural systems, could generate cascades of climate change impacts from the tropics that propagate to other ‘extra-‘ tropical natural systems and human communities globally.
