Government data revealed that sea surface temperatures in the waters around South Korea and across East Asia reached some of the highest levels on record last year. This acceleration of climate risks poses a significant threat to marine ecosystems and the region's fishing industry. The near-record heat in East Asia's seas is part of a larger trend of global oceans storing more warmth, emphasizing the urgent need for comprehensive climate action to mitigate the impact on marine life and the livelihoods of communities relying on fishing. This story underscores the pressing need for sustainable practices to combat the escalating climate risks in marine environments.
