Humpback whale resurgence: Climate change or population recovery?
Scientists are surprised by the increasing presence of humpback whales in the waters off the coast of Great Britain. Experts are pondering whether this is a sign of the recovery of the whale population or the impact of climate change.
In recent weeks, scientists have noted an increase in the number of humpbacks in British waters, from the Scilly Isles to the eastern coasts. Between 29 December 2024 and 8 January of this year, 17 individuals of this species were observed near the archipelago. One of them is known to scientists from the distinctive markings on its tail fin. Intriguingly, humpbacks were also seen in the eastern part of the English Channel, suggesting they might be restoring old migration routes.
Hypotheses formulated
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 British coast. Ruth Williams from Wildlife Trusts also indicates 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 are food for humpbacks, which could explain their presence.
Threats to humpbacks
Scientists are concerned that humpbacks may be prone to 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 examined for their impact on marine ecosystems. "Renewable energy is necessary, but not at the cost of wildlife," notes Waller, as quoted by "The Guardian."
Observations of humpbacks in Britain are fascinating but require further research to understand their causes and effects on the ecosystem. Scientists will continue monitoring these phenomena to better understand changes in the behaviours of these majestic mammals.
