Now, as climate change warms the sea and melts that ice, they have adapted. Scientists describe the result as seasonal Arctic "feeding frenzies" - part of a major regime shift in the ocean environment along East Greenland.Image source, Fernando UgarteImage caption, A humpback whale feeding in coastal subarctic waters The change is dramatic: ship-based surveys in the region did not record a single humpback whale sighting there until 2006. In 2007, seven humpbacks were seen, and by 2024, there were 150 ship-based sightings of these giant whales.The first syste...
