Chronic Ocean Heating Fuels 'Staggering' Loss of Marine Life, Study Finds

A recent study reveals significant marine life decline linked to chronic ocean heating. Researchers analyzed 33,000 populations in the northern hemisphere from 1993 to 2021, isolating the impact of seabed warming. They found a 7.2% decline in fish levels for every 0.1°C of warming per decade, with some areas experiencing up to 19.8% loss in a single year. The study emphasizes that even small temperature increases over time lead to a substantial and concerning loss of marine biomass.
