Warming North Sea May Invite Great White Sharks Back to British Waters
Record‑high temperatures in the North Sea have revived interest in ancient marine predators, with n…
Executive Overview: A Warming Sea Signals a Predator ComebackLast year the North Sea hit an average surface temperature of 11.6°C, the warmest since records began in 1969, and researchers now argue that such conditions could lure great white sharks back to British coasts.Record‑Breaking Temperatures and Fossil DiscoveriesScientists led by Olivier Lambert of the Royal Belgian Institute of Natural Sciences examined 5‑million‑year‑old whale fossils from North Sea sediments. The fossils contained shark tooth fragments, identifying a bluntnose sixgill shark and the extinct mako shark Cosmopolitodus hastalis, a close relative of today’s great white.Temperature Data and Historical Climate Context1969‑present: long‑term monitoring shows a steady rise in sea‑surface temperature.2025: average surface temperature reached 11.6°C, the highest on record.5 million years ago: North Sea waters were warmer, supporting diverse whale and shark species.Ecological Implications: Apex Predators on the HorizonModern North Sea habitats are too shallow for large whales, yet warming waters are already attracting more dolphins and seals. Lambert’s team predicts that these prey species could, in turn, draw great white sharks and other large marine predators into UK waters, reshaping the food web.Looking Ahead: Scenarios for a Changing Marine LandscapeIf the warming trend continues, the North Sea could become a seasonal corridor for great whites, potentially increasing human‑shark interactions and prompting new management strategies for fisheries and coastal safety. Ongoing monitoring will be crucial to anticipate and mitigate ecological and socio‑economic impacts.
