A recent four-year study indicates that rising sea temperatures around the UK and the north-east Atlantic may destabilize marine food webs, posing risks to ocean health and food security by 2050. The research challenges previous assumptions about increasing marine biodiversity in middle latitudes, revealing a potential imbalance between predator and prey species.
The study forecasts a 12% increase in fish and seabed invertebrate diversity, while key plankton groups may decline by 3% to 7%. This uneven shift could disrupt marine ecosystems, highlighting the need for policymakers to consider climate impacts in biodiversity management strategies.
