Humpback resurgence off UK coast sparks climate debate

In recent weeks, scientists have noticed an increase in the number of humpbacks in the waters of Great Britain, from the Scilly Archipelago to the eastern coasts. Between December 29, 2024, and January 8 of this year, 17 individuals of this species were observed near the archipelago. One of them is known to scientists because of the distinctive markings on its tail fin. Interestingly, humpbacks were also spotted in the eastern part of the English Channel, suggesting they might be restoring old migration routes.

The presence of humpbacks may be related to the increased availability of food, such as krill and small fish, which are moving closer to the coasts of Great Britain. Ruth Williams from Wildlife Trusts also highlights that climate change is affecting the migration of these fish.

Carl Chapman, a tour guide, noticed a humpback near minke whales off the eastern coast of England. According to him, the higher water temperature is attracting fish that serve as food for humpbacks, which could explain their presence.

Scientists are concerned that humpbacks may be at risk of collisions with ships. Specialists also worry about the impact of new underwater power cables on marine mammals. Emma Waller from Kent Wildlife Trust emphasizes that energy projects should be thoroughly assessed for their impact on marine ecosystems. "Renewable energy is necessary, but not at the expense of wildlife," notes Waller, as quoted by "The Guardian."

Observations of humpbacks in Great Britain are fascinating but require further research to comprehend their causes and effects on the ecosystem. Scientists will continue monitoring these phenomena to better understand changes in the behaviours of these majestic mammals.
