Ocean temperatures are reaching a boiling point with marine heatwaves wreaking havoc across the Pacific, a disaster for marine ecosystems.

Rising ocean temperatures are sweeping the seas, breaking records and creating problematic conditions for marine life. Unlike heatwaves on land, periods of abrupt ocean warming can surge for months or years. Around the world these ‘marine heatwaves’ have led to mass species mortality and displacement events, economic declines and habitat loss. New research reveals that even areas of the ocean protected from fishing are still vulnerable to these extreme events fueled by climate change.

The vast majority of global marine food supplies are threatened by climate change, according to a new study. 

MInimizing risk to the aquatic and marine environment is crucial to feeding a growing global population

Many of the world’s largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark study has shown.
