Giant Whales Move Into Greenland Waters as Sea Ice Disappears

Giant whales are increasingly moving into previously inaccessible waters along Greenland’s east coast as rising temperatures cause sea ice to disappear. A decades-long study found that fin, humpback and minke whales are now feeding in ice-free coastal waters during summer, marking a major shift in the region’s marine ecosystem.

Researchers recorded a sharp rise in whale activity, with aerial surveys, satellite tracking and observations from Inuit hunters providing evidence of the change. An estimated 4,000 humpback whales, 6,000 fin whales and 6,000 minke whales visited the Greenland Sea in summer 2024. Scientists believe warmer waters and increased food availability are attracting the whales to the area.

While some whale species appear to be benefiting from the changing conditions, Arctic species such as narwhals and belugas could face growing pressure as their traditional habitat changes. Scientists say the movement represents a major ecological shift, highlighting how climate change is creating new opportunities for some marine species while threatening others.
